Abstract:
The morphology of galaxies provide us with a unique tool to connect
and understand other related physical properties and their changes
over the course of cosmic time. Only recently, thanks to big and/or
deep surveys, we have access to a wealth of data for unprecedented
number galaxies. The morphological catalogue of the OTELO survey
galaxies detected in Hubble Space Telescope (HST)-ACS F814W images is
presented. We explore various methods from previous works to separate
early-type (ET) and late-type (LT) galaxies classified via spectral
energy distribution (SED) fittings using galaxy templates. Together
with this article we release the catalogue containing main
morphological parameters in F606W and F814W bands derived for more
than 8000 sources. The morphological analysis is based on the
single-Sersic profile fit. The GALAPAGOS-2 software was used in order
to provide multi-wavelength morphological parameters fitted
simultaneously in two HST-ACS bands. GALAPAGOS-2 detects, prepares
guess values for GALFIT-M, and provides the best-fitting single-Sersic
model in both bands for each source. Stellar masses were estimated
using synthetic rest-frame magnitudes recovered from SED-fitting of
galaxy templates. The morphological catalogue is complemented with
concentration indexes from a separate SExtractor dual, high dynamical
range mode.
A total of 8812 sources were successfully fitted with single-Sersic
profiles. The analysis of a carefully selected sample of ∼3000 sources
up to z_phot=2 is presented in this work, from which 873 sources were
not detected in previous studies. We found no statistical evidence for
the evolution of low-mass end of mass-size relation for ET and LT
since z=2. Furthermore, we found a good agreement on the median size
evolution for ET and LT galaxies, for a given stellar-mass, with data
in the literature. Compared to previous works on faint field galaxies,
we found similarities regarding rest-frame colours, Sersic and
concentration indices.
Description:
The catalogue contain basic morphological parameters derived using
GALAPAGOS-2 software. The galaxy sample is derived from the OTELO
survey. See also Bongiovanni et al. (2019A&A...631A...9B 2019A&A...631A...9B) for the
