Evolution of the Mass-Metallicity Relation from Redshift to the Local Universe
Danial Langeroodi, Jens Hjorth, Wenlei Chen +17
A tight positive correlation between the stellar mass and the gas-phase metallicity of galaxies has been observed at low redshifts. The redshift evolution of this correlation can s…
Flashlights: More than A Dozen High-Significance Microlensing Events of Extremely Magnified Stars in Galaxies at Redshifts z=0.7-1.5
Patrick L. Kelly, Wenlei Chen, Amruth Alfred +23
Once only accessible in nearby galaxies, we can now study individual stars across much of the observable universe aided by galaxy-cluster gravitational lenses. When a star, compact…
Low Metallicity Galaxies from the Dark Energy Survey
Yu-Heng Lin, Claudia Scarlata, Vihang Mehta +6
We present a new selection of 358 blue compact dwarf galaxies (BCDs) from 5,000 square degrees in the Dark Energy Survey (DES), and the spectroscopic follow-up of a subsample of 68…
A spatially resolved analysis of star-formation burstiness by comparing UV and H in galaxies at z1 with UVCANDELS
Vihang Mehta, Harry I. Teplitz, Claudia Scarlata +30
The UltraViolet imaging of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey Fields (UVCANDELS) program provides HST/UVIS F275W imaging for four CANDELS fields. We…
The Origin of the Observed Lyman alpha EW Distribution of Dwarf Galaxies at z~2
C. Snapp-Kolas, B. Siana, T. Gburek +5
We present a rest-UV selected sample of 32 lensed galaxies at observed with joint Keck/LRIS rest-UV and Keck/MOSFIRE rest-optical spectra behind the clusters Abell 1689,…
On the triggering of extreme starburst events in low-metallicity galaxies: a deep search for companions of Green Peas
Lauren Laufman, Claudia Scarlata, Matthew Hayes +1
Green pea galaxies are starbursting, low-mass galaxies that are good analogues to star-forming galaxies in the early universe. We perform a survey of 23 Green Peas using the MUSE I…
