LATIS: Constraints on the Galaxy-halo Connection at from Galaxy-galaxy and Galaxy-Ly Clustering
Andrew B. Newman, Mahdi Qezlou, Nima Chartab +6
The connection between galaxies and dark matter halos is often quantified using the stellar mass-halo mass (SMHM) relation. Optical and near-infrared imaging surveys have led to a…
Boosting Line Intensity Map Signal-to-Noise with the Ly- Forest Cross-Correlation
Mahdi Qezlou, Simeon Bird, Adam Lidz +6
We forecast the prospects for cross-correlating future line intensity mapping (LIM) surveys with the current and future Ly- forest data. We use large cosmological hydrodynamic s…
LATIS: The Ly Tomography IMACS Survey
Andrew B. Newman, Gwen C. Rudie, Guillermo A. Blanc +15
We introduce LATIS, the Ly Tomography IMACS Survey, a spectroscopic survey at Magellan designed to map the z=2.2-2.8 intergalactic medium (IGM) in three dimensions by observing…
Inflation and Dark Energy from spectroscopy at
Simone Ferraro, Michael J. Wilson, Muntazir Abidi +140
The expansion of the Universe is understood to have accelerated during two epochs: in its very first moments during a period of Inflation and much more recently, at , when D…
Metal-line absorption around 2.4 star-forming galaxies in the Keck Baryonic Structure Survey
Monica L. Turner, Joop Schaye, Charles C. Steidel +2
(Abridged) We study metal absorption around 854 2.4 star-forming galaxies taken from the Keck Baryonic Structure Survey (KBSS). The galaxies examined in this work lie in…
A measurement of galaxy halo mass from the surrounding HI Lyα absorption
Olivera Rakic, Joop Schaye, Charles C. Steidel +3
We measure the dark matter halo masses of z~2.36 UV color-selected star-forming galaxies by matching the observed median HI Lyα absorption around them, as observed in the spectra o…
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…
The Column Density Distribution and Continuum Opacity of the Intergalactic and Circumgalactic Medium at Redshift <z>=2.4
Gwen C. Rudie, Charles C. Steidel, Alice E. Shapley +1
We present new high-precision measurements of the opacity of the intergalactic and circumgalactic medium (IGM, CGM) at <z>=2.4. Using Voigt profile fits to the full Lyman alpha and…
The explosion energy of early stellar populations: The Fe-peak element ratios in low metallicity damped Lyman-alpha systems
Ryan Cooke, Max Pettini, Regina A. Jorgenson +3
The relative abundances of the Fe-peak elements (Ti-Zn) at the lowest metallicities are intimately linked to the physics of core-collapse supernova explosions. With a sample of 25…
The Temperature-Density Relation in the Intergalactic Medium at Redshift <z>=2.4
Gwen C. Rudie, Charles C. Steidel, Max Pettini
We present new measurements of the temperature-density (T-rho) relation for neutral hydrogen in the 2.0 < z < 2.8 intergalactic medium (IGM) using a sample of ~6000 individual HI a…
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…
Neutral hydrogen optical depth near star-forming galaxies at z~2.4 in the Keck Baryonic Structure Survey
Olivera Rakic, Joop Schaye, Charles C. Steidel +1
[Abridged] We study the interface between galaxies and the intergalactic medium by measuring the absorption by neutral hydrogen in the vicinity of star-forming galaxies at z~2.4. O…
The most metal-poor damped Lyman-alpha systems: Insights into chemical evolution in the very metal-poor regime

We present a high spectral resolution survey of the most metal-poor damped Lyman-alpha absorption systems (DLAs) aimed at probing the nature and nucleosynthesis of the earliest gen…
A Carbon-enhanced Metal-poor Damped Lyman alpha System: Probing Gas from Population III Nucleosynthesis?
Ryan Cooke, Max Pettini, Charles C. Steidel +2
We present high resolution observations of an extremely metal-poor damped Lyman-alpha system, at z_abs = 2.3400972 in the spectrum of the QSO J0035-0918, exhibiting an abundance pa…
Calibrating Galaxy Redshifts Using Absorption by the Surrounding Intergalactic Medium
Olivera Rakic, Joop Schaye, Charles C. Steidel +1
Rest-frame UV spectral lines of star-forming galaxies are systematically offset from the galaxies' systemic redshifts, probably because of large-scale outflows. We calibrate galaxy…

The sightline to the brighter member of the gravitationally lensed quasar pair UM 673A,B intersects a damped Lyman-alpha system (DLA) at z = 1.62650 which, because of its low redsh…
