Abstract:
We present a catalogue of dynamical properties for 2368 late-type
galaxies from the MaNGA survey. The latter complements the catalogue
of photometric properties for the same sample based on deep optical
dark energy sky instrument legacy imaging survey (DESI) photometry
processed with AUTOPROF . Rotation curves (RCs), extracted by
model-fitting H α velocity maps from the MaNGA Data Analysis
Pipeline, extend out to 1.4 (1.9) Re for the primary (secondary)
MaNGA samples, respectively. The RCs and ancillary MaNGA Pipe3D data
products were used to construct various fundamental galaxy scaling
relations that are also compared uniformly with similar relations from
numerical investigation of a hundred astrophysical object (NIHAO)
zoom-in simulations. Simulated NIHAO galaxies were found to broadly
reproduce the observed MaNGA galaxy population for
log(M*/M☉) > 8.5. Some discrepancies remain, such as those
pertaining to central stellar densities and the diversity of RCs due
to strong feedback schemes. Also presented are spatially resolved
scatters for the velocity-size-stellar mass (VRM*) structural
relations using MaNGA and NIHAO samples. The scatter for these
relations in the galaxian interiors is a consequence of the diversity
of inner RC shapes, while scatter in the outskirts is dictated by the
large range of stellar surface densities, which is itself driven by
sporadic star formation. The detailed, spatially resolved scatter
analysis highlights the complex interplay between local and global
astrophysical processes and provides a strong constraint to numerical
simulations.
Description:
Given their importance for constraining galaxy formation and evolution
models, studies of galaxy scaling relations have enjoyed a rich
historyThe slope, zero-point, and scatter of scaling relations encode
critical information about the structure of galaxies and provide
stringent constraints to galaxy formation models . Such data-model
comparisons require large, unbiased, multiband observed galaxy data
and modern, state-of-the-art galaxy formation simulations.The advent
of galaxy surveys with large-scale integral field spectroscopy, such
as MaNGA, ATLAS3D, and CALIFA has opened up new areas of investigation
with high-quality, spatially resolved dynamical and chemical
properties of galaxies. For instance, the coupling of IFU data with
deep multiband photometric observations allows detailed studies of
different astrophysical processes, such as star formation interactions
between baryon and dark matter, impact of environment, chemical
evolution, angular momentum distributions and more.
In our case we focus on providing the most recent, up-to-date, and
uniform comparison between simulations and observations of galaxies is
the motivation for this study. Combining the MaNGA photometric
catalogue (Arora et al. 2021MNRAS.505.3135A 2021MNRAS.505.3135A, A21) and auxiliary data from
Pipe3D (Sanchez et al. 2018RMxAA..54..217S 2018RMxAA..54..217S) with robust rotation
curves yields an extensive catalogue of inferred galaxy structural
data which is ideal for comparison with galaxy formation models as
NIHAO one.
Our photometrc data is firstly composed of non-parametric multiband
photometric and environmental properties for ∼4500 MaNGA galaxies as
in A21 relying on DESI grz-band images and WXSC catalog (Jarrett et
al. 2019ApJS..245...25J 2019ApJS..245...25J, Cat. J/ApJS/245/25). SB profiles parameters
were extracted with autoprof whcih also finds an accurate galaxian
centre for each galaxy image before fitting elliptical isophotes. The
centre, position angle (PA), and ellipticities of each isophote are
fit to the DESI r-band images for MaNGA galaxies (i.e. more details in
section 2). Also, due to lowest sensitivity to dust extinction, all
photometric properties were calculated using the DESI z-band surface
brightness profiles. Next, we used SDSS dr17 data (Abdurro'uf et al.
2022ApJS..259...35A 2022ApJS..259...35A, Cat. III/286) and DESI yielding to 5166 LTGs as
classified in Dominguez Sanchez et al. (2018MNRAS.476.3661D 2018MNRAS.476.3661D, Cat.
J/MNRAS/476/3661). Then, RCs were obtained by fitting the following
model to the MaNGA Hα velocity map as described in section
2.2. Quality cuts are applied to retain 2368 galaxies that have robust
photometry and RCs. Their fit output kinematic results are presented
in table.dat.
The study continues to photometric parameters extractions as dynamical
masses following to computations of structural scaling relations,
projected size-stellar mass relation and size-velocity relation,
stellar Tully-Fisher relation, selection functions of observed and
simulated galaxy for comparison work in section 3 and 4. Finally, in
section 5 and section 6, the study focus on multiple galaxy physical
scaling relations and spatially resolved properties.
