Compact Size, High SFR: Defining Morphological Features of Ly-Emitters
Keunho Kim, Anahita Alavi, Christopher Snapp-Kolas +7
The mechanisms of Ly photon escape are key to understanding galaxy evolution and cosmic reionization, yet remain poorly understood. We investigate the UV-continuum sizes of 23 L…
The Rest-UV Spectral Properties of Dwarf Galaxies at
Christopher Snapp-Kolas, Brian Siana, Timothy Gburek +4
Rest-UV spectroscopy can constrain properties of the stellar populations, outflows, covering fractions, and can indirectly constrain the Lyman continuum escape fraction of galaxies…
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,…
The Detection of [O III]4363 in a Lensed, Dwarf Galaxy at = 2.59: Testing Metallicity Indicators and Scaling Relations at High Redshift and Low Mass
Timothy Gburek, Brian Siana, Anahita Alavi +6
We present Keck/MOSFIRE and Keck/LRIS spectroscopy of A1689-217, a lensed (magnification ), star-forming (SFR 16 ), dwarf (log($M_\ast/M_\odot…
