Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory

Courtney D. Dressing, Danica Adams, Evelyne Alecian +324

The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…

Learning the Universe with the 2nd Generation of CAMELS: Varying 35 parameters of the IllustrisTNG model in (50Mpc/h)^3 boxes

Shy Genel, Yongseok Jo, Boon Kiat Oh +10

We present a new set of 1,192 cosmological simulations as part of the CAMELS project, in which a space of 35 cosmological, astrophysical, and numerical parameters is explored aroun…

Implications of the nanoHertz Gravitational-Wave Background for Galactic Feedback and Massive Black Hole Growth

Megan Taylor Tillman, Blakesley Burkhart, Chiara M. F. Mingarelli +5

We investigate how pulsar timing array (PTA) measurements of the nanoHertz gravitational-wave background (GWB) can constrain models for the growth history of supermassive black hol…

Exploring the impact of AGN feedback model variations on the Lyman- Forest Flux Power Spectrum

Megan Pirecki, Megan Taylor Tillman, Blakesley Burkhart +2

We study the effects of varying different Active Galactic Nuclei (AGN) feedback parameters on the Lyman- (Ly) forest 1D transmitted flux power spectrum (P1D). We use the Cosm…

How does feedback affect the star formation histories of galaxies?

Kartheik G. Iyer, Tjitske K. Starkenburg, Greg L. Bryan +20

Star formation in galaxies is regulated by the interplay of a range of processes that shape the multiphase gas in the interstellar and circumgalactic media. Using the CAMELS suite…

Reconstructing galactic feedback history via the Lyman- forest with Habitable Worlds Observatory

Megan T. Tillman, Joseph N. Burchett, Blakesley Burkhart +2

Recent studies have focused on the low- Ly forest as a potential constraint on galactic feedback, as different AGN and stellar feedback models in hydrodynamic simulations pro…

The Effects of AGN Feedback on the Lyman- Forest Flux Power Spectrum

Megan Taylor Tillman, Blakesley Burkhart, Stephanie Tonnesen +2

We study the effects of AGN feedback on the Lyman- forest 1D flux power spectrum (P1D). Using the Simba cosmological-hydrodynamic simulations, we examine the impact that adding…

An Exploration of AGN and Stellar Feedback Effects in the Intergalactic Medium via the Low Redshift Lyman- Forest

Megan Taylor Tillman, Blakesley Burkhart, Stephanie Tonnesen +9

We explore the role of galactic feedback on the low redshift Lyman- (Ly)~forest () statistics and its potential to alter the thermal state of the intergalactic…

X-ray Absorption Lines in the Warm-Hot Intergalactic Medium: Probing Chandra observations with the CAMEL simulations

Amanda Butler Contreras, Erwin T. Lau, Benjamin D. Oppenheimer +5

Known as the "Missing Baryon Problem", about one-third of baryons in the local universe remain unaccounted for. The missing baryons are thought to reside in the warm-hot intergalac…

Efficient long-range AGN feedback affects the low redshift Lyman- forest

Megan Taylor Tillman, Blakesley Burkhart, Stephanie Tonnesen +5

Active galactic nuclei (AGN) feedback models are generally calibrated to reproduce galaxy observables such as the stellar mass function and the bimodality in galaxy colors. We use…

Running Late: Testing Delayed Supermassive Black Hole Growth Models Against the Quasar Luminosity Function

Megan Taylor Tillman, Sarah Wellons, Claude-André Faucher-Giguère +2

Observations of massive galaxies at low redshift have revealed approximately linear scaling relations between the mass of a supermassive black hole (SMBH) and properties of its hos…
