531. Massive discs in cosmological simulations
ID:
ivo://CDS.VizieR/J/A+A/640/A70
Title:
Massive discs in cosmological simulations
Short Name:
J/A+A/640/A70
Date:
21 Oct 2021
Publisher:
CDS
Description:
We investigate the disc-halo connection in massive (M*>5x10^10^M_{sun}_) disc galaxies from the cosmological hydrodynamical simulations EAGLE and IllustrisTNG, and compare it with that inferred from the study of HI rotation curves in nearby massive spirals from the Spitzer Photometry and Accurate Rotation Curves (SPARC) dataset. We find that discrepancies between the simulated and observed discs arise both on global and on local scales. Globally, the simulated discs inhabit halos that are a factor 4 (in EAGLE) and 2 (in IllustrisTNG) more massive than those derived from the rotation curve analysis of the observed dataset. We also use synthetic rotation curves of the simulated discs to demonstrate that the recovery of the halo masses from rotation curves are not systematically biased. We find that the simulations predict dark-matter dominated systems with stellar-to-total enclosed mass ratios that are a factor of 1.5-2 smaller than real galaxies at all radii. This is an alternative manifestation of the `failed feedback problem', since it indicates that simulated halos hosting massive discs have been too inefficient at converting their baryons into stars, possibly due to an overly efficient stellar and/or AGN feedback implementation.
532. Massive galaxies in CANDELS-UDS field
ID:

Title:
Massive galaxies in CANDELS-UDS field
Short Name:
J/MNRAS/427/1666
Date:
21 Oct 2021
Publisher:
CDS
Description:
We have used high-resolution, Hubble Space Telescope, near-infrared imaging to conduct a detailed analysis of the morphological properties of the most massive galaxies at high redshift, modelling the WFC3/IR H_160_-band images of the =~200 galaxies in the CANDELS-UDS field with photometric redshifts 1<z<3, and stellar masses M_*_>10^11^M_{sun}_. We have explored the results of fitting single-Sersic and bulge+disc models, and have investigated the additional errors and potential biases introduced by uncertainties in the background and the on-image point spread function.
533. MASSIVE Survey. VII.
ID:
ivo://CDS.VizieR/J/MNRAS/471/1428
Title:
MASSIVE Survey. VII.
Short Name:
J/MNRAS/471/1428
Date:
21 Oct 2021
Publisher:
CDS
Description:
We analyse the environmental properties of 370 local early-type galaxies (ETGs) in the MASSIVE and ATLAS^3D^ surveys, two complementary volume-limited integral-field spectroscopic (IFS) galaxy surveys spanning absolute K-band magnitude - 21.5>=M_K_>=-26.6, or stellar mass 8*10^9^<~M*<~2*10^12^M{sun}. We find these galaxies to reside in a diverse range of environments measured by four methods: group membership (whether a galaxy is a brightest group/cluster galaxy, satellite or isolated), halo mass, large-scale mass density (measured over a few Mpc) and local mass density (measured within the Nth neighbour). The spatially resolved IFS stellar kinematics provide robust measurements of the spin parameter {lambda}_e_ and enable us to examine the relationship among {lambda}_e_, M* and galaxy environment. We find a strong correlation between {lambda}_e_ and M*, where the average {lambda}_e_ decreases from ~0.4 to below 0.1 with increasing mass, and the fraction of slow rotators f_slow_ increase from ~10 to 90 per cent. We show for the first time that at fixed M*, there are almost no trends between galaxy spin and environment; the apparent kinematic morphology-density relation for ETGs is therefore primarily driven by M* and is accounted for by the joint correlations between M* and spin, and between M* and environment. A possible exception is that the increased f_slow_ at high local density is slightly more than expected based only on these joint correlations. Our results suggest that the physical processes responsible for building up the present-day stellar masses of massive galaxies are also very efficient at reducing their spin, in any environment.
534. MASSIV I. Sample properties
ID:
ivo://CDS.VizieR/J/A+A/539/A91
Title:
MASSIV I. Sample properties
Short Name:
J/A+A/539/A91
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present the global properties (redshift, SED-based stellar mass and star formation rate, [OII]3727 flux and equivalent width) of the MASSIV sample. It contains 84 star-forming galaxies in the redshift range 0.9<z<1.8 selected from the VVDS and observed with the SINFONI/VLT integral-field spectrograph. The main aims of the MASSIV survey is to probe the kinematics and chemical properties of a significant and representative sample of high-redshift galaxies with star formation rate >5M_{sun}_/yr.
535. 2MASS-selected Flat Galaxy Catalog (2MFGC)
ID:
ivo://CDS.VizieR/J/other/BSAO/57.5
Title:
2MASS-selected Flat Galaxy Catalog (2MFGC)
Short Name:
J/other/BSAO/57.
Date:
21 Oct 2021
Publisher:
CDS
Description:
An all-sky catalog of 18020 disc-like galaxies is presented. The galaxies are selected from the Extended Source Catalog of the Two Micron All-Sky Survey (XSC 2MASS) basing on their 2MASS axial ratio a/b>=3. The Catalog contains data on magnitudes of a galaxy in the J, H, Ks bands, its axial ratio, positional angle, index of luminosity concentration, as well as identification of the galaxy with the LEDA and the NED databases. Unlike the available optical catalogs, the new 2MFGC catalog seems to be more suitable to study cosmic streaming on a scale of z~0.1. The dipole moment of distribution of the bright (K<11mag) 2MFGC objects (l=227{deg}, b=41{deg} or SGL=90{deg}, SGB=-43{deg}) lies within statistical errors (+/-15{deg}) in the direction of the IRAS dipole and the optical RFGC dipole.
536. 2MASS-selected Isolated Galaxies (2MIG)
ID:
ivo://CDS.VizieR/VII/257
Title:
2MASS-selected Isolated Galaxies (2MIG)
Short Name:
VII/257
Date:
21 Oct 2021
Publisher:
CDS
Description:
We undertook searches for isolated galaxies based on automatic selection of infrared sources from the Two Micron All-Sky Survey (2MASS, Cat. II/246) followed by a visual inspection of their surrounding. Using a modified criterion by Karachentseva (1973SoSAO...8....3K), we compiled a catalog of 3227 isolated galaxies (2MIG) containing 6% of 2MASS Extended Sources (2MASX, Cat. VII/233) brighter than K_s_=12mag with angular diameters a_K_<=30". The most isolated 2493 galaxies among them enter in the 2MASS Very Isolated Galaxy Catalog, 2MVIG. Being situated in the regions of extremely low mass density, the 2MVIG galaxies can serve as a reference sample for investigation the influence of environment on structure and evolution of galaxies.

Space Telescope Science Institute Archive
Description:
3D-HST is a near-infrared spectroscopic survey with the Hubble Space Telescope designed to study the physical processes that shape galaxies in the distant Universe (GO-12177 and GO-12328; PI: Pieter van Dokkum). This Treasury program was allocated 248 orbits of HST time during Cycles 18 and 19. 3D-HST is surveying ~600 square arcminutes of well-studied extragalactic survey fields (AEGIS, COSMOS, GOODS-S, UKIDSS-UDS) with two orbits of primary WFC3/G141 grism coverage and two to four orbits with ACS/G800L coverage. 3D-HST now provides the critical third dimension - redshift - for ~10,000 galaxies at z>1. This is the epoch when ~60% of the star formation in the Universe took place, the number density of quasars peaked, the first galaxies stopped forming stars and the structural regularity that we see in galaxies today emerged. The 3D-HST project details can be found in "3D-HST: A Wide-Field Grism Spectroscopic Survey with the Hubble Space Telescope", Brammer et al., 2012, ApJ, 758L. The survey is optimally designed for the study of galaxy evolution over 1 < < 3.5. The science objectives include: disentangling the processes that regulate star-formation in massive galaxies, evaluating the role of environment and mergers in shaping the galaxy population, and resolving the growth of disks and bulges, spatially and spectrally.
