The DESI PRObabilistic Value-added Bright Galaxy Survey (PROVABGS) Mock Challenge

The Astrophysical Journal, 2023
The PRObabilistic Value-added Bright Galaxy Survey (PROVABGS) catalog will provide measurements of galaxy properties, such as stellar mass ( M _* ), star formation rate (SFR), stellar metallicity ( Z ), and stellar age ( t _age ), for >10 million ...

Two-phase galaxy formation: the evolutionary properties of galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2010
We use our model for the formation and evolution of galaxies within a two-phase galaxy formation scenario, showing that the high-redshift domain typically supports the growth of spheroidal systems, whereas at low redshifts the predominant baryonic growth mechanism is quiescent and may therefore support the growth of a disc structure.

CEERS Key Paper. V. Galaxies at 4 < z < 9 Are Bluer than They Appear–Characterizing Galaxy Stellar Populations from Rest-frame ∼1 μm Imaging

The Astrophysical Journal Letters, 2023
We present results from the Cosmic Evolution Early Release Survey on the stellar population parameters for 28 galaxies with redshifts 4 < z < 9 using imaging data from the James Webb Space Telescope (JWST) Mid-Infrared Instrument (MIRI) combined with ...

Properties of the Environment of Galaxies in Clusters of Galaxies CL 0024+1654 and RX J0152.7−1357

Journal of Mathematical and Fundamental Sciences, 2021
We report the results of combined analyses of X-ray and optical data of two galaxy clusters, CL 0024+1654 and RX J0152.7−1357 at redshift z = 0.395 and z = 0.830, respectively, offering a holistic physical description of the two clusters.

K-band luminosity–density relation at fixed parameters or for different galaxy families

Open Physics, 2020
Using the apparent magnitude-limited Main galaxy sample of the Sloan Digital Sky Survey Data Release 10, we examine the K-band luminosity–density relation at fixed parameters or for different galaxy families.

Photometric Objects Around Cosmic Webs (PAC) Delineated in a Spectroscopic Survey. IV. High-precision Constraints on the Evolution of the Stellar–Halo Mass Relation at Redshift z < 0.7

The Astrophysical Journal, 2023
Taking advantage of the Photometric objects Around Cosmic webs method developed in Paper I, we measure the excess surface density ${\bar{n}}_{2}{w}_{{\rm{p}}}$ of the photometric objects around spectroscopic objects down to stellar masses 10 ^8.0 M _ ...

A multiscale approach to environment [PDF]

, 2009
Physical processes influencing the properties of galaxies can be traced by the dependence and evolution of galaxy properties on their environment. A detailed understanding of this dependence can only be gained through comparison of observations with ...

Properties of Primitive Galaxies

Proceedings of the International Astronomical Union, 2022
AbstractWe report on a study of 9 nearby primitive galaxies observed by Hubble’s COS far-UV spectrograph that can serve as templates of high-z galaxies to be observed by JWST. By “primitive galaxies,” we mean galaxies having a low stellar mass, and low gas metallicity, , whether they are local or at high redshift.
