Constraints from dwarf galaxies on black hole seeding and growth models with current and future surveys
Urmila Chadayammuri, Akos Bogdan, Angelo Ricarte +1
Dwarf galaxies are promising test beds for constraining models of supermassive and intermediate-mass black holes (MBH) via their black hole occupation fraction (BHOF). Disentanglin…
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…
Line Emission Mapper (LEM): Probing the physics of cosmic ecosystems
Ralph Kraft, Maxim Markevitch, Caroline Kilbourne +107
The Line Emission Mapper (LEM) is an X-ray Probe for the 2030s that will answer the outstanding questions of the Universe's structure formation. It will also provide transformative…
X-ray Halos around Massive Galaxies: Data and Theory
Akos Bogdan, Mark Vogelsberger
The presence of gaseous X-ray halos around massive galaxies is a basic prediction of all past and modern structure formation simulations. The importance of these X-ray halos is fur…
The X-ray Angular Power Spectrum of Extended Sources in the eROSITA Final Equatorial Depth Survey
Erwin T. Lau, Akos Bogdan, Urmila Chadayammuri +3
The eROSITA Final Equatorial Depth Survey (eFEDS), with a sky area of 140 square degrees with depth equivalent to the equatorial patch of the final eROSITA all-sky survey, represen…
Testing galaxy feedback models with the first resolved profiles of the circumgalactic medium
Urmila Chadayammuri, Akos Bogdan, Benjamin Oppenheimer +3
The hot ( K) phase of the circumgalactic medium (CGM) contains a large fraction of baryons in galaxies. It also retains signatures of the processes that shaped the galaxies,…
