Constraints on Hyperluminous QSO Lifetimes via Fluorescent Lya Emitters at Z~2.7
Ryan F. Trainor, Charles C. Steidel
We present observations of a population of Lya emitters (LAEs) exhibiting fluorescent emission via the reprocessing of ionizing radiation from nearby hyperluminous QSOs. These LAEs…
The Mass-Metallicity Relation Of A Z~2 Protocluster With MOSFIRE
Kristin R. Kulas, Ian S. McLean, Alice E. Shapley +7
We present Keck/MOSFIRE observations of the role of environment in the formation of galaxies at z~2. Using K-band spectroscopy of H-alpha and [N II] emission lines, we have analyze…
Narrowband Lyman-Continuum Imaging of Galaxies at z ~ 2.85
Robin E. Mostardi, Alice E. Shapley, Daniel B. Nestor +3
We present results from a survey for z~2.85 Lyman-Continuum (LyC) emission in the HS1549+1933 field and place constraints on the amount of ionizing radiation escaping from star-for…
The halo masses and galaxy environments of hyperluminous QSOs at z~2.7 in the Keck Baryonic Structure Survey
Ryan F. Trainor, Charles C. Steidel
We present an analysis of the galaxy distribution surrounding 15 of the most luminous (>10^{14} L_sun; M_1450 ~ -30) QSOs in the sky with z~2.7. Our data are drawn from the Keck Ba…
The Gaseous Environment of High-z Galaxies: Precision Measurements of Neutral Hydrogen in the Circumgalactic Medium of z ~ 2-3 Galaxies in the Keck Baryonic Structure Survey
Gwen C. Rudie, Charles C. Steidel, Ryan F. Trainor +7
We present results from the Keck Baryonic Structure Survey (KBSS), a unique spectroscopic survey designed to explore the connection between galaxies and intergalactic baryons. The…
