A Novel Framework for Modeling Weakly Lensing Shear Using Kinematics and Imaging at Moderate Redshift
Brian DiGiorgio, Kevin Bundy, Kyle B. Westfall +2
Kinematic weak lensing describes the distortion of a galaxy's projected velocity field due to lensing shear, an effect recently reported for the first time by Gurri et al. based on…

A precise extragalactic test of General Relativity
Thomas E. Collett, Lindsay J. Oldham, Russell J. Smith +7
Einstein's theory of gravity, General Relativity, has been precisely tested on Solar System scales, but the long-range nature of gravity is still poorly constrained. The nearby str…

Measurement of the small-scale structure of the intergalactic medium using close quasar pairs
Alberto Rorai, Joseph F. Hennawi, Jose Oñorbe +6
The distribution of diffuse gas in the intergalactic medium (IGM) imprints a series of hydrogen absorption lines on the spectra of distant background quasars known as the Lyman-…
The Stacked Lyman-Alpha Emission Profile from the Circum-Galactic Medium of z~2 Quasars
Fabrizio Arrigoni Battaia, Joseph F. Hennawi, Sebastiano Cantalupo +1
In the context of the FLASHLIGHT survey, we obtained deep narrow band images of 15 quasars with GMOS on Gemini-South in an effort to measure Ly emission from circum- an…
On the connection between the metal-enriched intergalactic medium and galaxies: an OVI-galaxy cross-correlation study at

We present new results on the auto- and cross-correlation functions of galaxies and OVI absorbers in a comoving volume at . We use a sample of 51,29…
Shadow of a Colossus: A z=2.45 Galaxy Protocluster Detected in 3D Ly-a Forest Tomographic Mapping of the COSMOS Field

We present and make publicly available the first data release (DR1) of the Keck Observatory Database of Ionized Absorption toward Quasars (KODIAQ) survey. The KODIAQ survey is aime…
Can AGN feedback break the self-similarity of galaxies, groups, and clusters?
M. Gaspari, F. Brighenti, P. Temi +1
It is commonly thought that AGN feedback can break the self-similar scaling relations of galaxies, groups, and clusters. Using high-resolution 3D hydrodynamic simulations, we isola…
A cosmic web filament revealed in Lyman-alpha emission around a luminous high-redshift quasar
Sebastiano Cantalupo, Fabrizio Arrigoni-Battaia, J. Xavier Prochaska +2
Simulations of structure formation in the Universe predict that galaxies are embedded in a "cosmic web", where the majority of baryons reside as rarefied and highly ionized gas. Th…

We compare the predictions of three independently developed semi-analytic galaxy formation models that are being used to aid in the interpretation of results from the CANDELS surve…
