Galactic Populations of LISA DWD Binaries

These COSMIC simulation outputs and assembled galactic populations of    Double White Dwarf (DWD) binaries    represent the work published by V. Delfavero et al,    in https://arxiv.org/abs/2409.15230

The COSMIC version used in these simulations is 3.4.10

The git repository for the accompanying code which built this dataset    will be available at https://gitlab.com/xevra/basil-cosmic    upon the publication of our article.

Also useful is the fork of ldasoft used in this pipeline:    https://github.com/xevra/ldasoft

Please cite this work if you use the included data in a publication.

-------------------------------------------------------------------------------Summary-------------------------------------------------------------------------------Params_[MODEL].ini    This initialization file was used for COSMIC,        for the runs tagged with [MODEL].

[MODEL]_[KSTAR1]_[KSTAR2]_[METALLICITY_BIN].tar.gz    This tarball contains the outputs from one run of COSMIC,        using Params_[MODEL].ini, for a type of binary indicated by        [KSTAR1] and [KSTAR2] according to COSMIC syntax,        and for the [METALLICITY_BIN]'th metallicity bin.

[MODEL]_COSMIC.hdf5    This hdf5 database holds the DWD population outputs for all 60        COSMIC simulations in a compressed format.    It only holds information about binary systems at the end        of evolution (conv, according to COSMIC syntax).    It does not contain the evolutionary history of individual binaries        (the bpp information, according to COSMIC syntax).

[MODEL]_m12i-000_LISA.nal.hdf5    This hdf5 database holds the LISA "resolved" population of DWD binaries        for a single realization of a Milky-Way-like galaxy.    It also stores many attributes indicating assumptions and various        population statistics.    The "nal" extension indicates that this database contains        truncated Gaussian likelihood models for the resolved population        of LISA DWDs,        which can be loaded by the gwalk code (https://gitlab.com/xevra/gwalk).    This database can also be explored by any hdf5 library (such as h5py).

[MODEL]_m12i-000_LISA.hdf5    This hdf5 database holds all of the LISA-band binaries (f_GW > 10^-4 Hz)        for a single galaxy realization.

[MODEL]_m12i-000_LISA.txt.gz    This text file stores the inputs for ldasoft gbfisher analysis,        for a specific galaxy realization under assumptions        broadly described by [MODEL]See README.txt for full description-------------------------------------------------------------------------------Funding-------------------------------------------------------------------------------VD is supported by an appointment to the NASA Postdoctoral Program at the NASA Goddard Space Flight Center administered by Oak Ridge Associated Universities under contract NPP-GSFC-NOV21-0031.
