An Improved UV–Optical Diagnostic for Rejuvenating Galaxies in the Local Universe and Implications for Galaxy Evolution

The Astrophysical Journal
Rejuvenating galaxies are important probes of galaxy evolution, yet identifying them observationally is challenging, as constraining recent star formation histories requires both photometric and spectroscopic data.

The Massive and Distant Clusters of WISE Survey 2: Detection of Splashback Radii in Galaxy Cluster Total Light Stacks

The Astrophysical Journal
The splashback radius, the radius of the apocenter of the first orbit of infalling material, is a measurable quantity marking the boundary between a galaxy cluster and its infalling region.

Luminosity Function of Galaxies in Voids: A Modification Inspired by Excursion Set Theory

The Astrophysical Journal
In the standard picture of cosmology, the galaxies reside in dark matter (DM) halos. DM halos are distributed in the cosmic web in different environments.

Virgo Filaments. IV. Using WISE to Measure the Modification of Star-forming Disks in the Extended Regions Around the Virgo Cluster

The Astrophysical Journal
Recent theoretical work and targeted observational studies suggest that filaments are sites of galaxy preprocessing. The aim of the WISESize project is to directly probe galaxies over the full range of environments to quantify and characterize extrinsic ...

The effects of merging and environment on galaxies and clusters of galaxies

, 2008
This thesis addresses two fundamental questions in astrophysics: (i) To what extent is environment a driver of galaxy evolution? And (ii) How does hierarchical structure formation affect the galaxy environment? The former is addressed by examining the environments of starburst galaxies, the latter by examining clusters undergoing major mergers with ...
