VizieR Online Data Catalog: The synthetic Emission Line COSMOS catalogue (Saito+, 2020)
Abstract
Laigle et al. (2016ApJS..224...24L, Cat. J/ApJS/224/24) provide the most updated photometric catalogue in the COSMOS field. 31 photometric bands nearly uniformly cover a wide range of wavelength from near ultraviolet (2000Å) to mid-infrared (105Å). The COSMOS2015 catalogue includes a homogeneous population of galaxies essentially selected in near-infrared (Ks=<24.7 in ultra-deep field).
In this paper, we select 518404 objects over 1.38deg2 [corresponding to AUVISTA&A!OPT&ACOSMOS in Table 7 of Laigle et al. (2016ApJS..224...24L, Cat. J/ApJS/224/24)] that are classified as 'galaxies' in the catalogue. Note that, even though X-ray sources are removed in this classification, active galactic nuclei (AGNs) can be still included. In order to calibrate our method, we make use of two data sets of EL fluxes from the zCOSMOS-Bright (Lilly et al. 2007ApJS..172...70L, Cat. J/ApJS/172/70) and the 3D-HST (Brammer et al. 2012ApJS..200...13B; Momcheva et al. 2016ApJS..225...27M, Cat. J/ApJS/225/27) surveys. The wavelength coverage of zCOSMOS and 3D-HST is 5500<λ<9600Å and 11000<λ<17000Å, respectively. We use an empirical but physically motivated approach to model the galaxy EL fluxes in the COSMOS field, where deep multiband photometric data sets are available. We perform a SED fitting to COSMOS2015 galaxies including a careful EL flux modelling based on the number of photoionizing photons predicted by the stellar continuum template.
