The BRIDGE Survey. I. Metallicities and Physical Properties of Gas Probing the Circumgalactic Medium at Cosmic Noon
Saloni Deepak, Nicolas Lehner, J. Christopher Howk +3
We present BRIDGE-I, a metallicity survey of \HI-selected absorbers probing ``CGM-like'' gas () at Cosmic Noon (), the epoch of peak…
The GOLIATH Survey: OVI Absorption Reveals CGM Evolution through the Starburst-to-Quiescent Transition in Massive Galaxies
Derick Flores, Rongmon Bordoloi, Jason Tumlinson +12
We present the GOLIATH survey (Galaxies, Outflows, and the Lifecycle of Immense, Active, Transforming Halos), a study of the multiphase circumgalactic medium (CGM) of massive ($\la…
Predicted Capabilities of the SPRITE SmallSat for a Low-Redshift Lyman Continuum Emission Survey
Yi Hang Valerie Wong, Brian Fleming, Elena Carlson +13
Ionizing Lyman continuum (LyC; ) radiation from low-redshift () galaxies provides crucial insight into the processes that contributed to cosmi…
Push-broom Mapping of Galaxies and Supernova Remnants with the SPRITE CubeSat
Elena Carlson, Brian Fleming, Yi Hang Valerie Wong +12
Supernovae (SNe) enrich and energize the surrounding interstellar medium (ISM) and are a key mechanism in the galaxy feedback cycle. The heating of the ISM by supernova shocks, and…
Evolution of the Ionizing Photon Luminosity Function
Stephan R. McCandliss, Swara Ravindranath, Sangeeta Malhotra +6
Counting the number and brightness of ionizing radiation sources out to a redshift of z ~ 1.2 will revolutionize our understanding of how the ionizing background is created and sus…
Project AMIGA: The Inner Circumgalactic Medium of Andromeda from Thick Disk to Halo
Nicolas Lehner, J. Christopher Howk, Lucy Collins +22
The inner circumgalactic medium (CGM) of galaxies, where disk and halo processes intersect, remains poorly characterized despite its critical role in regulating galaxy evolution. W…
Tilsotua: Reproducing Slitmask Sky Positions for use with the LRIS Multislit Archive
Jessica Sullivan, J. Christopher Howk, Nicolas Lehner +2
We present tilsotua, a code that calculates sky positions of the slits from Low-Resolution Imaging Spectrograph (LRIS) slitmasks used in multislit observations. Raw data for the Ke…
Spatially Resolved Circumgalactic Medium around a Star-Forming Galaxy Driving a Galactic Outflow at
Ahmed Shaban, Rongmon Bordoloi, John M. O'Meara +6
We report the small-scale spatial variation in cool () Mg II absorption detected in the circumgalactic medium (CGM) of a star-forming galaxy at . The CG…
FOGGIE X: Characterizing the Small-Scale Structure of the CGM and its Imprint on Observables
Ramona Augustin, Jason Tumlinson, Molly S. Peeples +11
One of the main unknowns in galaxy evolution is how gas flows into and out of galaxies in the circumgalactic medium (CGM). Studies observing the CGM in absorption using multiple or…
The COS CGM Compendium V: The Dichotomy of OVI Associated with Low- and High-Metallicity Cool Gas at z < 1
Sameer, Nicolas Lehner, J. Christopher Howk +3
We analyze the \ovi\ content and kinematics for 126 {\hi}-selected absorbers at for which the metallicities of their cool photoionized phase have be…
The Nature of Ionized Gas in the Milky Way Galactic Fountain
Jessica K. Werk, Kate H. R. Rubin, Hannah V. Bish +6
We address the spatial scale, ionization structure, mass and metal content of gas at the Milky Way disk-halo interface detected as absorption in the foreground of seven closely-spa…
Figuring Out Gas & Galaxies in Enzo (FOGGIE). II. Emission from the z=3 Circumgalactic Medium
Lauren Corlies, Molly S. Peeples, Jason Tumlinson +4
Observing the circumgalactic medium (CGM) in emission provides 3D maps of the spatial and kinematic extent of the gas that fuels galaxies and receives their feedback. We present mo…
Figuring Out Gas & Galaxies in Enzo (FOGGIE). I. Resolving Simulated Circumgalactic Absorption at 2 < z < 2.5
Molly S. Peeples, Lauren Corlies, Jason Tumlinson +7
We present simulations from the new "Figuring Out Gas & Galaxies in Enzo" (FOGGIE) project. In contrast to most extant simulations of galaxy formation, which concentrate computatio…
The COS CGM Compendium (CCC). I: Survey Design and Initial Results
Nicolas Lehner, Christopher B. Wotta, J. Christopher Howk +3
