Environmental Dependence of Different Colors for the Apparent Magnitude-Limited Main Galaxy Sample of the SDSS DR7

Open Astronomy, 2013
The apparent magnitude-limited Main galaxy sample of the Sloan Digital Sky Survey Data Release 7 is used to investigate the environmental dependence of u–r, u–g, g–r, r–i and i–z colors.

CHILES. VIII. Probing the Evolution of Average H I Content in Star-forming Galaxies over the Past 5 Gyr

The Astrophysical Journal
Utilizing the COSMOS H I Large Extragalactic Survey (CHILES) data set, we investigate the evolution of the average atomic neutral hydrogen (H I ) properties of galaxies over the continuous redshift range 0.09

The Thickness of Galaxy Disks from z = 5 to 0 Probed by JWST

The Astrophysical Journal Letters
Although a thick disk is a structure prevalent in local disk galaxies and also present in our home Galaxy, its formation and evolution are still unclear.

Discovery of Local Analogs to JWST’s Little Red Dots

The Astrophysical Journal Letters
Recently, the James Webb Space Telescope has revealed a new class of high-redshift (high- z , z  > 4) compact galaxies that are red in the rest-frame optical and blue in the rest-frame UV with V-shaped spectral energy distributions (SEDs), referred to as

On the Very Bright Dropouts Selected Using the James Webb Space Telescope NIRCam Instrument

The Astrophysical Journal
The selection of candidate high-redshift galaxies using the dropout technique targeting the Lyman-break signature sometimes yields very bright objects that are too luminous to be easily explained if they are indeed at the expected redshifts.
