Virtual UniverseMachine sheds light galaxy evolution
2019/10/21
How do galaxies such as our Milky Way come into existence? How do they grow and change over time? The science behind galaxy formation has long been a puzzle, but a University of Arizona-led team of sc...
WVU astrophysicists part of gravitational wave search that provides insights into galaxy evolution and mergers
WVU astrophysicists gravitational wave search galaxy evolution and mergers
2016/4/13
On the heels of their participation in the historic research that resulted in the detection of gravitational waves, West Virginia University astrophysicists continue to plow new ground ...
A Deep Radio Survey of Abell 2125. II. Accelerated Galaxy Evolution during a Cluster-Cluster Merger
Abell galaxies
2014/12/24
Using our extensive radio, optical, near-IR, and X-ray imaging and spectroscopy, we consider the reason for the unusually large number of radio-detected galaxies, mostly found outside the cluster core...
Galaxy evolution in Hickson compact groups: the role of ram-pressure stripping and strangulation
evolution interactions
2014/12/23
Galaxies in compact groups tend to be deficient in neutral hydrogen compared to isolated galaxies of similar optical properties. In order to investigate the role played by a hot intragroup medium (IGM...
A complete view of galaxy evolution: panchromatic luminosity functions and the generation of metals
typical galaxies galaxies
2014/12/22
When and how did galaxies form and their metals accumulate? Over the last decade, this has moved from an archeological question to a live investigation: there is now a broad picture of the evolution o...
Galactic Bulge Feedback and its Impact on Galaxy Evolution
galactic feedback hydrodynamics intergalactic medium Intestellar Medium supernova remnants X-ray
2014/12/9
Galactic bulges of early-type spirals and elliptical galaxies comprise primarily old stars, which account for more than half of the total stellar mass in the local Universe. These stars collectively g...
Galaxy evolution at high-redshift: Millimeter-wavelength surveys with the AzTEC camera
Pure sciences Dust Galaxy evolution Galaxies Star formation Submillimeter
2014/12/9
Galaxies detected by their thermal dust emission at submillimeter (submm) and millimeter (mm) wavelengths comprise a population of massive, intensely star-forming systems in the early Universe. These ...
The Role Of Stellar Feedback In Galaxy Evolution
Pure sciences Galaxies X-ray Stellar feedback Galaxy evolution
2014/12/9
Aiming at understanding the role of stellar feedback in galaxy evolution, I present a study of the hot interstellar medium in several representative galaxies, based primarily on X-ray observations as ...
Galaxy evolution in groups and clusters: star formation rates, red sequence fractions, and the persistent bimodality
methods: statistical-galaxies: groups: general-galaxies: clusters:general-galaxies: haloes-galaxies: evolution-galaxies: star formation
2011/10/17
Using galaxy group/cluster catalogs created from the Sloan Digital Sky Survey Data Release 7, we examine in detail the specific star formation rate (SSFR) distribution of satellite galaxies and its de...
A modified star formation law as a solution to open problems in galaxy evolution
galaxies: evolution – galaxies: formation – galaxies: stellar content –galaxies: haloes
2011/10/13
In order to reproduce the low mass end of the stellar mass function, most current models of galaxy evolution invoke very efficient supernova feedback. This solution seems to suffer from several shortc...
Surveying the Agents of Galaxy Evolution in the Tidally-Stripped, Low Metallicity Small Magellanic Cloud (SAGE-SMC). I. Overview
Surveying Agents Galaxy Evolution Tidally-Stripped Small Magellanic Cloud
2011/10/13
The Small Magellanic Cloud (SMC) provides a unique laboratory for the study of the lifecycle of dust given its low metallicity (~1/5 solar) and relative proximity (~60 kpc). This motivated the SAGE-SM...

Galaxy: halo Galaxies: evolution Magellanic Clouds Hydrodynamics Instabilities
2010/10/29
The Magellanic Stream (MS) is the nearest example of a gaseous
trail formed by interacting galaxies. While the substantial gas masses in these kinds
of circumgalactic structures are postulated to re...
Proposed cosmological surveys will make use of photometric redshifts of galaxies that are significantly fainter than any complete spectroscopic redshift surveys that exist to train the photo-z methods...
