Figuring Out Gas & Galaxies in Enzo (FOGGIE). XV. Examining the Spatial and Kinematic Relationship between Circumgalactic Mg II and O VI

Mackenzie Ticoras, Brian W. O'Shea, Claire Kopenhafer +9

Understanding the thermodynamic properties of the circumgalactic medium (CGM) is key to uncovering the baryon cycle in galaxies. Here we present spatial and kinematic relationships…

Metagalactic Ultraviolet Background Tables for Calculating Diffuse Astrophysical Plasma Properties

Elias Taira, Claire Kopenhafer, Brian W. O'Shea

In developing a deeper understanding of the Circumgalactic Medium, one feature that is poorly understood is the nature of the ultraviolet background (UVB) and its impact on observe…

Impacts of the Metagalactic Ultraviolet Background on Circumgalactic Medium Absorption Systems

Elias Taira, Claire Kopenhafer, Brian W. Oshea +5

Among the many different pieces of physics that go into simulations of the circumgalactic medium (CGM), the metagalactic ultraviolet background (UVB) plays a significant role in de…

Seeking Self-Regulating Simulations of Idealized Milky Way-Like Galaxies

Claire Kopenhafer, Brian W. O'Shea, G. Mark Voit

Precipitation is potentially a mechanism through which the circumgalactic medium (CGM) can regulate a galaxy's star formation. Here we present idealized simulations of isolated Mil…

Figuring Out Gas & Galaxies In Enzo (FOGGIE) VI: The Circumgalactic Medium of Galaxies is Supported in an Emergent, Non-Hydrostatic Equilibrium

Cassandra Lochhaas, Jason Tumlinson, Molly S. Peeples +9

The circumgalactic medium (CGM) is often assumed to exist in or near hydrostatic equilibrium with the regulation of accretion and the effects of feedback treated as perturbations t…

KODIAQ-Z: Metals and Baryons in the Cool Intergalactic and Circumgalactic Gas at 2.2<z<3.6

Nicolas Lehner, Claire Kopenhafer, John O'Meara +8

We present the KODIAQ-Z survey aimed to characterize the cool, photoionized gas at 2.2<z<3.6 in 202 HI-selected absorbers with 14.6<log N(HI)<20, i.e., the gaseous interface betwee…

The breakBRD Breakdown: Using IllustrisTNG to Track the Quenching of an Observationally-Motivated Sample of Centrally Star-Forming Galaxies

Claire Kopenhafer, Tjitske K. Starkenburg, Stephanie Tonnesen +1

The observed breakBRD ("break bulges in red disks") galaxies are a nearby sample of face-on disk galaxies with particularly centrally concentrated star formation: they have red dis…

What Is Inside Matters: Simulated Green Valley Galaxies Have Centrally Concentrated Star Formation

Tjitske K. Starkenburg, Stephanie Tonnesen, Claire Kopenhafer

In spatially resolved galaxy observations, star formation rate radial profiles are found to correlate with total specific star formation rates. A central depletion in star formatio…
