A dense, metal-rich absorber driven by a heavily dust-obscured galaxy: The direct evidence of CGM enrichment at
Qinyue Fei, Seiji Fujimoto, Gabriel Brammer +23
We report the serendipitous discovery of a dense, metal-enriched circumgalactic medium (CGM) absorber at z=7.03, together with its host galaxy, identified along the sightline towar…
Strongest constraints on dark acoustic oscillations from the Lyman-alpha forest
Zhihan Yuan, Caleb Gemmell, Keir K. Rogers +4
We set the first constraints on a small-scale dark acoustic oscillation (DAO) in the linear matter power spectrum arising from dark sector interactions, with a full forward model o…
Active Galactic Nuclei-driven Metallicity Enrichment in the Interstellar Medium of Mrk 573
D. Ł. Król, P. Zhu, G. Fabbiano +5
We present the first spatially resolved at pc scale application of AGN-specific metallicity diagnostics for the nearby Compton-thick Seyfert 2 galaxy Mrk 573 ()…
The Two Component Circumgalactic Medium Emission around z~2 Radio-loud Quasars
Sanchit Sabhlok, Shelley A. Wright, Andrey Vayner +7
We present Ly, He II and C IV observations of 7 redshift ~ 2 radio-loud quasars observed using the Keck Cosmic Web Imager (KCWI) and compare it to observed radio jet emission us…
Very Massive Stars and High N/O: A Tale of the Nitrogen-enriched Super Star Cluster in the Sunburst Arc
Yanlong Shi, Liang Dai, Norman Murray +3
The lensed Sunburst Arc () hosts a young (--), massive (), compact () Lyman-continuum (LyC) le…
Oxygen Abundance Throughout the Dwarf Starburst IC 10
Maren Cosens, Shelley A. Wright, Karin Sandstrom +5
Measurements of oxygen abundance throughout galaxies provide insight to the formation histories and ongoing processes. Here we present a study of the gas phase oxygen abundance in…
Probing and resolving AGN disks with ultrafast photon counters
Neal Dalal, Marios Galanis, Charles Gammie +2
Intensity interferometry is a technique developed many decades ago, that has recently enjoyed a renaissance thanks in part to advances in photodetector technology. We investigate t…
Circumgalactic Environments around Distant Quasars 3C 9 and 4C 05.84
Sanchit Sabhlok, Shelley A. Wright, Andrey Vayner +6
We present results from the ``Quasar hosts Unveiled by high Angular Resolution Techniques" (QUART) survey studying the Circumgalactic Medium (CGM) by observing rest-frame UV emissi…
Dissipative Dark Substructure: The Consequences of Atomic Dark Matter on Milky Way Analog Subhalos
Caleb Gemmell, Sandip Roy, Xuejian Shen +4
Using cosmological hydrodynamical zoom-in simulations, we explore the properties of subhalos in Milky Way analogs that contain a sub-component of Atomic Dark Matter (ADM). ADM diff…
Binary Stars Can Provide the "Missing Photons" Needed for Reionization
Xiangcheng Ma, Philip F. Hopkins, Daniel Kasen +4
Empirical constraints on reionization require galactic ionizing photon escape fractions fesc>20%, but recent high-resolution radiation-hydrodynamic calculations have consistently f…
A Stellar Feedback Origin for Neutral Hydrogen in High-Redshift Quasar-Mass Halos
C. -A. Faucher-Giguere, R. Feldmann, E. Quataert +3
Observations reveal that quasar host halos at z~2 have large covering fractions of cool dense gas (>~60% for Lyman limit systems within a projected virial radius). Most simulations…
Mapping the Outer Edge of the Young Stellar Cluster in the Galactic Center
Morten N. Støstad, Tuan Do, Norm Murray +3
We present new near-infrared spectroscopic observations of the outer edges of the young stellar cluster around the supermassive black hole at the Galactic center. The observations…
Neutral hydrogen in galaxy halos at the peak of the cosmic star formation history
C. -A. Faucher-Giguere, P. F. Hopkins, D. Keres +3
We use high-resolution cosmological zoom-in simulations from the FIRE project to make predictions for the covering fractions of neutral hydrogen around galaxies at z=2-4. These sim…
Resolving The Generation of Starburst Winds in Galaxy Mergers
Philip F. Hopkins, Dusan Keres, Norman Murray +3
We study galaxy super-winds driven in major mergers, using pc-resolution simulations with detailed models for stellar feedback that can self-consistently follow the formation/destr…
Self-Regulated Star Formation in Galaxies via Momentum Input from Massive Stars
Philip F. Hopkins, Eliot Quataert, Norman Murray
Feedback from massive stars is believed to play a critical role in shaping the galaxy mass function, the structure of the interstellar medium (ISM), and the low efficiency of star…
