Selected properties of galaxy and SMBH populations (Spinoso et al. 2023)
Description
This record presents the catalogs of galaxy and Black Holes properties associated to the two runs of the modified version of the L-Galaxies Semi-Analytic Model (SAM) presented in Spinoso et al. 2023. These catalogs are aimed at providing the basic properties to study the population of Black Holes (BHs) and their host galaxies across cosmic times, obtained by running the L-Galaxies SAM over the whole Millennium-II box (see Boylan-Kolchin et al. 2009). The L-Galaxies SAM outputs summarized in these catalogs were obtained at several redshifts/snapshots, for two different runs which differ for the initial occupation fraction of BHs at the time of their formation. This initial occupation fraction is parametrized by the Gp parameter(see Spinoso et al. 2023 for details), with the two runs being characterized by Gp=1 and Gp=0.01. The catalogs are organized in two group of files, one group for each run. Each of these groups is composed by 18 different files, one per each availablle redshift, roughly corresponding to: z = 0, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15. The two group of files can be easily distinguished by their names: indeed, the strings "Gp1" and "Gp001" are referred to the runs corresponding to the Gp=1 and Gp=0.01 values, respectively. In addition, every file includes a string of the form: "z[x.yz]" which specifies its redshift.
The content of these catalogs is as follows: each redshift-file contains the same collection of arrays, each array being a galaxy or BH property. At each redshift, L-Galaxies outputs properties for the number 'NGAL' of galaxies identified in the Millennium-II box, at that specific redshift/snapshot. Therefore, most of the arrays have length equal to 'NGAL' (i.e. one value per each galaxy). Few of the arrays have a length of N * NGAL (i.e. N values per each galaxy). The content, units and data type of these arrays are as follows:
- "StellarMass" - Total stellar mass of each galaxy - [10^10 Msun / h] - array[NGAL]
- "Sfr" - Star formation rate of each galaxy - [Msun / yr] - array[NGAL]
- "SeedMass" - BH-seed mass. 7 values per galaxy; one value for each of the 7 possible BH-seed "flavors" modeled - [10^10 Msun / h] - array[NGAL, 7]
- "Rvir" - Virial radius of the DM halo hosting each galaxy - [Mpc / h] - array[NGAL]
- "Pos" - X, Y and Z position of each galaxy - [Mpc / h] - array[NGAL, 3]
- "Mvir" - Virial mass of the DM halo hosting each galaxy - [10^10 Msun / h] - array[NGAL]
- "Lbol" - Bolometric luminosity associated to the central AGN (==0 if the BH is not active) - [10^40 erg / s] - array[NGAL]
- "HotGas" - Mass of the hot-phase of each galaxy's gas component - [10^10 Msun / h] - array[NGAL]
- "fEDD" - Eddington ration (defined as Lbol/L_Edd, with L_Edd being the Eddington luminosity) for each AGN (==0 if the BH is not active) - [adim] - array[NGAL]
- "ColdGas" - Mass of the cold-phase of each galaxy's gas component - [10^10 Msun / h] - array[NGAL]
- "BlackHoleMass" - Mass of the central massive BH hosted by each galaxy (==0 if the galaxy does not host a central BH) - [10^10 Msun / h] - array[NGAL]
- "SeedType" - Identifier of the type of BH-seed which originated each BH (see below for details) - array[NGAL]
- "Redshift" - Redshift of each galaxy (within a single file, this is an array of identical values) - array[NGAL]
NOTE:
The model presented in Spinoso et al. 2023 follows 7 different types of BH-seeds. The "SeedMass" array contains 7 mass values (one for each of these types of BH-seeds) for each galaxy in the Millennium-II box.This is the reason why the data type of "SeedMass" is [NGAL, 7]. Each of these 7 values is the sum, across the whole evolution of each galaxy, of the contributions to the total BH mass coming from each BH-seed who merged to form the final BH. In the vast majority of cases, BHs are associated to only one type of BH-seed. In those cases, 6 out of the 7 "SeedMass" values would be zero. Each element of "SeedMass" corresponds to one type of BH seed according the following scheme:
SeedMass[0] : total seed mass of light-seeds inherited from the GQd model (see Spinoso et al. 2023 for details)
SeedMass[1] : total seed mass of heavy-seeds inherited from the GQd model (see Spinoso et al. 2023 for details)
SeedMass[2] : un-resolved mass-growth driven by gas-accretion before the halo hosting the BH was resolved
SeedMass[3] : total seed mass formed as light-seeds in L-Galaxies
SeedMass[4] : total seed mass formed as Direct-Collapse BHs (DCBHs)
SeedMass[5] : total seed mass formed as intermediate-mass BH originated via Runaway Stellar Mergers (RSM)
SeedMass[6] : total seed mass formed as Merger-Induced Direct-Collapse BH (miDCBH)
NOTE:
Similarly to "SeedMass", also the "Pos" array has more than one element per galaxy. These are the three cartesian positions of each galaxy.
NOTE:
The possible values of the "SeedType" array are as follows (see Spinoso et al. 2023 for details):
-1 - No BH seed (the galaxy never hosted a BH)
1 - light seed (PopIII remnant)
6 - Direct-Collapse BH (DCBH)
7 - intermediate-mass BH originated via Runaway Stellar Mergers (RSM)
8 - Merger-Induced Direct-Collapse BH (miDCBH)
9 - mixed type: light+DCBH (the BH is the result of hierarchical mergers between light and DCBH seeds)
10 - mixed type: light+RSM (the BH is the result of hierarchical mergers between light and RSM seeds)
