Output Analysis¶

Class providing on-the-fly analysis of Galacticus model outputs, computing statistics such as stellar mass functions, luminosity functions, size–mass relations, and other observational comparisons during the simulation run rather than as a post-processing step. Analyses are finalized (e.g. accumulated across trees and MPI tasks) after all trees have been processed, and results are written to the output HDF5 file. A log-likelihood method enables use within posterior sampling frameworks.

Default implementation: outputAnalysisNull

Methods¶

analyze → void

Extract properties from the given node at output index iOutput and accumulate them into the analysis statistic (e.g. histogram bin counts or likelihood contributions).

type (treeNode), intent(inout) :: node
integer(c_size_t), intent(in ) :: iOutput

newTree → void

Perform any initialization or bookkeeping required at the start of analyzing a new merger tree at output index iOutput, for example resetting per-tree accumulators.

type (mergerTree), intent(inout) :: tree
integer(c_size_t ), intent(in ) :: iOutput

finalize → void

Finalize the analysis after all trees and MPI tasks have been processed, computing derived statistics and writing results to the output HDF5 group specified by groupName.

type(varying_string), intent(in ), optional :: groupName

reduce → void

Reduce (aggregate) this analysis object’s accumulated statistics onto the reduced object, typically used for MPI reduction to combine results from multiple processes.

class(outputAnalysisClass), intent(inout) :: reduced

logLikelihood → double precision

Return the log-likelihood of the model predictions compared to the target observational data, summed over all bins or data points included in this analysis.

`outputAnalysisBlackHoleVsHaloMassRelation`¶

A black hole vs. halo mass relation output analysis class. Target data is read from an HDF5 file specified by the [fileNameTarget] parameter. This file must contain one or more groups named redshiftIntervalN where N is an integer. Each such group specifies the black hole mass–halo mass relation in one redshift interval, and must contain the following datasets and attributes:

dataset massHalo: halo mass in units of \(\mathrm{M}_\odot\);
dataset massBlackHole: black hole mass in units of \(\mathrm{M}_\odot\);
dataset massBlackHoleError: uncertainty in black hole mass in units of \(\mathrm{M}_\odot\);

dataset massBlackHoleScatterError: uncertainty in scatter in black hole mass in units of dex;
attribute redshiftMinimum: the minimum redshift associated with this redshift interval;
attribute redshiftMaximum: the maximum redshift associated with this redshift interval.

While not required, it is recommended that each of these datasets has attributes description and unitsInSI that provide a description of the dataset, and the multiplicative factor needed to convert them to SI standard units, respectively.

Additionally, the file must contain a cosmology group that specifies the cosmological model assumed in constructing the dataset, and which has attributes:

OmegaMatter: the matter density in units of the critical density, \(\Omega_\mathrm{M}\);

The file must have an attribute haloMassDefinition which specifies the halo mass definition assumed in constructing the dataset. Allowed values are:

'spherical collapse' or 'virial': halos are defined as have mean density contrasts given by spherical collapse calculations, e.g. Percival (2005);
'Bryan & Norman (1998)': halos are defined as have mean density contrasts given by the fitting formula of Bryan and Norman (1998);
'X * mean density': halos are defined as having mean densities equal to ;X times the mean density of the universe;
'X * critical density': halos are defined as having mean densities equal to ;X times the critical density of the universe;

Lastly, the file must have two attributes used to identify and level the dataset:

label: a space-free label that will be appended to the analysis group in the output, e.g. Leauthaud2012;
reference: a reference for the dataset suitable for inclusion in figures, e.g. Leauthaud et al. (2012).

`outputAnalysisCorrelationFunction`¶

A generic two-point correlation function output analysis class.

For constraints corresponding to (possibly, projected) correlation functions, the model expectation is computed using the halo model Cooray and Sheth (2002). For each model halo, each galaxy (satellite and central) is assessed to see if it meets the criteria for inclusion in the sample. Where the sample includes mass limits (either just a lower limit, or lower and upper limits) each galaxy is assigned a probability of inclusion in the sample based on its mass and the random error in mass. Thus, each halo is characterized by the probability of having a central galaxy in the sample, \(p^\mathrm{(c)}\), and \(N\) probabilities, \(p_i^\mathrm{(s)}\), of each satellite galaxy being in the sample. We assume binomial statistics for each galaxy’s probability of inclusion, and further assume that these probabilities are uncorrelated. Therefore, the contribution of the halo to the one- and two-halo terms of the power spectrum in the halo model are:

\[\Delta P^\mathrm{1h}(k) = {w \over n_\mathrm{gal}^2} \left[ p^\mathrm{(c)} \sum_{i=1}^N p^\mathrm{(s)} u(k|M) + \sum_{k=0}^N k(k-1) P\left(p_i^\mathrm{(s)},\ldots,p_N^{(s)}\right) u(k|M)^2 \right]\]

and

\[\Delta \sqrt{P^\mathrm{2h}}(k) = {w \over n_\mathrm{gal}} \sqrt{P^\mathrm{lin}}(k) b(M) u(k|M) \left[ p^\mathrm{(c)} + \sum_{i=1}^N p_i^\mathrm{(s)} \right],\]

respectively, where \(w\) is the weight of the halo (i.e. the number of such model halos expected per unit volume), \(b(M)\) is the bias of halos of mass \(M\), \(u(k|M)\) is the Fourier-transform of the halo density profile, and \(P_\mathrm{lin}(k)\) is the linear theory power spectrum, and \(P(p_1,\ldots,p_N)\) is the Poisson binomial distribution for \(N\) events with probabilities \(p_1,\ldots,p_N\). The contribution of the halo to the galaxy density, \(n_\mathrm{gal}\), is simply \(\Delta n_\mathrm{gal} = w \left[ p^\mathrm{(c)} + \sum_{i=1}^N p_i^\mathrm{(s)} \right]\).

`outputAnalysisMassFunctionHIALFALFAMartin2010`¶

An ALFALFA HI \(z\approx 0.0\) mass function output analysis class measured by Martin et al. (2010). HI mass estimates can be affected by HI self-absorption for highly inclined galaxies. Zwaan et al.

dataset massStellar: stellar mass in units of \(\mathrm{M}_\odot\);
dataset radiusEffective: effective radius in units of Mpc;
dataset radiusEffectiveError: uncertainty in effective radius in units of Mpc;
dataset radiusEffectiveScatter: scatter in effective radius in units of dex;
dataset radiusEffectiveScatterError: uncertainty in scatter in effective radius in units of dex;
attribute redshiftMinimum: the minimum redshift associated with this sample;
attribute redshiftMaximum: the maximum redshift associated with this sample.

Additionally, the file must contain a cosmology group that specifies the cosmological model assumed in constructing the dataset, and which has attributes:

OmegaMatter: the matter density in units of the critical density, \(\Omega_\mathrm{M}\);
OmegaDarkEnergy: the dark energy density in units of the critical density, \(\Omega_\Lambda\);
OmegaBaryon: the baryon density in units of the critical density, \(\Omega_\mathrm{b}\);
HubbleConstant: the Hubble constant in units of km/s/Mpc.

Each sampleN group must have an attribute selection which specifies the selection criterion used in constructing the dataset. Allowed values are:

'none': no selection criterion will be applied;
'star forming': only galaxies on or above the star forming main sequence are included;
'quiescent: only galaxies below the star forming main sequence are included.

For the “star forming” and “quiescent” options, a dataset mainSequenceSFR must be specified in the sampleN group which specifies the mean (of the logarithm of star formation rate in units of \(\mathrm{M}_\odot/\hbox{yr}^{-1}\)) of the star forming main sequence at the center of each bin, and an attribute offsetMainSequenceSFR which specifies an offset below the mean of the star forming main sequence below which galaxies are considered to be quiescent. That is, a galaxy will be classified as quiescent if

\[\log_{10} ( \dot{\phi} / \mathrm{M}_\odot \hbox{yr}^{-1}) < \log_{10} ( \dot{M}_{\star,ms} / \mathrm{M}_\odot \hbox{yr}^{-1}) - \Delta_{\star},\]

where \(\log_{10} ( \dot{\phi} / \mathrm{M}_\odot \hbox{yr}^{-1})\) is the star formation rate in the galaxy, \(\log_{10} ( \dot{M}_{\star,ms} / \mathrm{M}_\odot \hbox{yr}^{-1})\) is the mean of the star forming main sequence (as specified by mainSequenceSFR and interpolated to the stellar mass of the galaxy, and \(\Delta_{\star}\) is offsetMainSequenceSFR,

Lastly, the file must have two attributes used to identify and level the dataset:

label: a space-free label that will be appended to the analysis group in the output, e.g. vanDerWel2014;
reference: a reference for the dataset suitable for inclusion in figures, e.g. van der Wel et al. (2014).

`outputAnalysisVolumeFunction1D`¶

A generic 1D volume function (i.e. number density of objects binned by some property, e.g. a mass function) output analysis class.

In addition to the volume function itself, the covariance matrix, \(\mathbf{C}_\mathrm{model}\), of the mass function is also computed. The assumptions used when constructing the covariance matrix are controlled by the parameter [covarianceModel]. If set to binomial, then to construct \(\mathbf{C}_\mathrm{model}\) we make use of the fact that Galacticus works by sampling a set of tree “root masses” from the \(z=0\) dark matter halo mass function. From each root, a tree is grown, within which the physics of galaxy formation is then solved. Root masses are sampled uniformly from the halo mass function. That is, the cumulative halo mass function, \(N(M)\), is constructed between the maximum and minimum halo masses to be simulated. The number of root masses, \(N_\mathrm{r}\), to be used in a model evaluation is then determined. Root masses are then chosen such that

\[N(M_i) = N(M_\mathrm{min}) {i-1 \over N_\mathrm{r}-1}\]

for \(i=1\ldots N_\mathrm{r}\) (noting that \(N(M_\mathrm{max})=0\) by construction).

Consider first those galaxies which form in the main branch of each tree (i.e. those galaxies which are destined to become the central galaxy of the \(z=0\) halo). Suppose that we simulate \(N_k\) halos of root mass \(M_k\) at \(z=0\). In such halos the main branch galaxies will, at any time, have property values drawn from some distribution \(p_k(M_\star|t)\). The number of such galaxies contributing to bin \(i\) of the mass function is therefore binomially distributed with success probability \(p_{ik} = \int_{M_{i,\mathrm min}}^{M_{i,\mathrm max}} p_k(M_\star|t) \d M_\star\) and a sample size of \(N_k\).

Generalizing to consider all bins in our volume function, the number of galaxies in each bin will jointly follow a multinomial distribution. The contribution to the covariance matrix from these main branch galaxies is therefore:

\[\begin{split}\mathcal{C}_{ij} = \left\{ \begin{array}{ll} p_{ik}(1-p_{ik}) N_k w_k^2 & \hbox{ if } i = j \\ -p_{ik} p_{jk} N_k w_k^2 & \hbox{ otherwise,} \end{array} \right.\end{split}\]

where \(w_k\) is the weight to be assigned to each tree. To compute this covariance requires knowledge of the probabilities, \(p_{ik}\). We estimate these directly from the model. To do this, we bin trees into narrow bins of root mass and assume that \(p_{ik}\) does not vary significantly across the mass range of each bin. Using all realizations of trees that fall within a given bin, \(k\), we can directly estimate \(p_{ik}\). Similarly, \(N_k w_k^2\) is found by accumulating squared weights in bins of root mass. In computing \(p_{ik}\) and \(N_k\), the range of halo masses considered and the fineness of binning in halo mass are determined by the parameters [covarianceBinomialMassHaloMinimum], [covarianceBinomialMassHaloMaximum], and [covarianceBinomialBinsPerDecade].

If instead, [covarianceModel]\(=\)Poisson, the main branch galaxies are modeled as being sampled from a Poisson distribution (and so off-diagonal terms in the covariance matrix will be zero).

In addition to the main branch galaxies, each tree will contain a number of other galaxies (these will be “satellite” galaxies at \(z=0\), but at higher redshifts may still be central galaxies in their own halos). Tests have established that the number of satellites in halos is well described by a Poisson process. Note that, as described above, each galaxy contributes a Gaussian distribution to the mass function due to modeling of random errors in property value determinations. For main branch galaxies this is simply accounted for when accumulating the probabilities, \(p_{ik}\). For satellite galaxies, off-diagonal contributions to the covariance matrix arise as a result, \(C_{ij} = w_k f_i f_j\), where \(f_i\) is the fraction of the galaxy contributing to bin \(i\) of the mass function.

Methods

results — Return the results of the volume function operator.
finalizeAnalysis — Finalize the analysis of this function.
setReporting — Activate/deactivate reporting.
logLikelihoodWrite — Write the log-likelihood of this analysis to the output group. Child classes that compute their own log-likelihood should override this to avoid evaluating the parent-class logLikelihood method.
metadataWrite — Write class-specific metadata to the analysis output group. The default implementation does nothing; child classes may override it to add further attributes or datasets.
