THE EVOLUTION OF STAR FORMATION HISTORIES OF QUIESCENT GALAXIES [PDF]

The Astrophysical Journal, 2016
ABSTRACT Although there has been much progress in understanding how galaxies evolve, we still do not understand how and when they stop forming stars and become quiescent. We address this by applying our galaxy spectral energy distribution models, which incorporate physically motivated star formation histories (SFHs) from cosmological ...

The GALEX Extended Mission: Surveying UV Tracers of the Hidden Side of Galaxy Evolution [PDF]

, 2010
The Galaxy Evolution Explorer (GALEX) continues its surveys of the ultraviolet sky. GALEX surveys have supported the following galaxy evolution investigations: calibrating UV as a star formation rate tracer, using wide and deep surveys to measure star ...

The Physics of Galaxy Formation and Evolution

, 2016
The theoretical studies about galaxy formation and evolution are the subject of this Chapter. They started with the recognition that the Hubble sequence is not a simple morphological description of galaxies, but a possible scheme separating and characterizing the physical processes that bring galaxies to their present form.

Morphological Demographics of Galaxies at z ∼ 10–16: Log-normal Size Distribution and Exponential Profiles Consistent with the Disk Formation Scenario

The Astrophysical Journal
We homogeneously investigate the morphological properties of 169 galaxies at z  ∼ 10–16 with deep JWST NIRCam images employing our established techniques of GALFIT modeling and uncertainty evaluation (systematics+statistics).

The History of Galaxy Mergers in IllustrisTNG

Universe
The process of galaxy evolution over cosmic time is not yet fully understood, since there is a debate on the impact of galaxy collisions on the star formation and metallicity.

A Simple Technique for Predicting High-Redshift Galaxy Evolution

, 2015
We show that the ratio of galaxies' specific star formation rates (SSFRs) to their host halos' specific mass accretion rates (SMARs) strongly constrains how the galaxies' stellar masses, specific star formation rates, and host halo masses evolve over ...

The time-evolution of bias [PDF]

, 1998
We study the evolution of the bias factor b and the mass-galaxy correlation coefficient r in a simple analytic model for galaxy formation and the gravitational growth of clustering. The model shows that b and r can be strongly time-dependent, but tend to

And the winner is: galaxy mass

, 2011
The environment is known to affect the formation and evolution of galaxies considerably best visible through the well-known morphology-density relationship.

Evolution of the Physical Properties of the Most Massive Galaxies in Clusters and Their Protohalos

The Astrophysical Journal
We investigated the evolution of the physical properties of the brightest galaxies in clusters and their protohalos from z = 4 to z = 0. Galaxy clusters and groups are identified using a halo-based group finder applied to the COSMOS2020 galaxy catalog ...

Merger Induced Globular Cluster Formation and Galaxy Evolution [PDF]

, 2008
Based on the earlier work of Gunn and McCrea we model the formation of globular clusters in merging galaxies. Neutral hydrogen observations of dwarf irregular galaxies as well as more luminous systems are used to provide the key parameters of the model ...
