How Gas Accretion Feeds Galactic Disks

Stephanie H. Ho, Crystal L. Martin, Monica L. Turner

Numerous observations indicate that galaxies need a continuous gas supply to fuel star formation and explain the star formation history. However, direct observational evidence of g…

Heavy Element Absorption Systems at : Metal-Poor Neutral Gas and a Diminishing Signature of Highly Ionized Circumgalactic Matter

T. J. Cooper, R. A. Simcoe, K. L. Cooksey +5

Ratios of different ions of the same element encode ionization information independently from relative abundances in quasar absorption line systems, crucial for understanding the m…

An 800-million-solar-mass black hole in a significantly neutral Universe at redshift 7.5

E. Bañados, B. P. Venemans, C. Mazzucchelli +15

Quasars are the most luminous non-transient objects known and as a result they enable studies of the Universe at the earliest cosmic epochs. Despite extensive efforts, however, the…

The Sunburst Arc: Direct Lyman α escape observed in the brightest known lensed galaxy

T. Emil Rivera-Thorsen, Håkon Dahle, Max Gronke +6

We present rest-frame ultraviolet and optical spectroscopy of the brightest lensed galaxy yet discovered, at redshift z = 2.4. This source reveals a characteristic, triple-peaked L…

A comparison of observed and simulated absorption from HI, CIV, and SiIV around star-forming galaxies suggests redshift-space distortions are due to inflows

Monica L. Turner, Joop Schaye, Robert A. Crain +4

We study HI and metal-line absorption around star-forming galaxies by comparing an analysis of data from the Keck Baryonic Structure Survey to mock spectra generated fr…

Mg II Absorption at 2<z<7 with Magellan/FIRE, III. Full Statistics of Absorption Towards 100 High-Redshift QSOs

Shi-Fan S. Chen, Robert A. Simcoe, Paul Torrey +12

We present final statistics from a survey for intervening MgII absorption towards 100 quasars with emission redshifts between and . Using infrared spectra from Mag…
