Unraveling the Mysteries of Galaxy Clusters: Recurrent Inference Deconvolution of X-ray Spectra
Carter Rhea, Julie Hlavacek-Larrondo, Ralph Kraft +3
In the realm of X-ray spectral analysis, the true nature of spectra has remained elusive, as observed spectra have long been the outcome of convolution between instrumental respons…
LEM All-Sky Survey: Soft X-ray Sky at Microcalorimeter Resolution
Ildar Khabibullin, Massimiliano Galeazzi, Akos Bogdan +23
The Line Emission Mapper (LEM) is an X-ray Probe with with spectral resolution ~2 eV FWHM from 0.2 to 2.5 keV and effective area >2,500 cm at 1 keV, covering a 33 arcmin diamet…
Mapping the Intracluster Medium in the Era of High-resolution X-ray Spectroscopy
Congyao Zhang, Irina Zhuravleva, Maxim Markevitch +24
High-resolution spectroscopy in soft X-rays will open a new window to map multiphase gas in galaxy clusters and probe physics of the intracluster medium (ICM), including chemical e…
Probing extreme black-hole outflows on short timescales via high spectral-resolution X-ray imagers
Ciro Pinto, James F. Steiner, Arash Bodaghee +7
We investigate outflows and the physics of super-Eddington versus sub-Eddington regimes in black hole systems. Our focus is on prospective science using next-generation high-resolu…
Revolutionary Solar System Science Enabled by the Line Emission Mapper X-ray Probe
William R. Dunn, Dimitra Koutroumpa, Jennifer A. Carter +27
The Line Emission Mapper's (LEM's) exquisite spectral resolution and effective area will open new research domains in Astrophysics, Planetary Science and Heliophysics. LEM will pro…
UNCOVER: The growth of the first massive black holes from JWST/NIRSpec -- spectroscopic redshift confirmation of an X-ray luminous AGN at z=10.1
Andy D. Goulding, Jenny E. Greene, David J. Setton +27
The James Webb Space Telescope is now detecting early black holes (BHs) as they transition from "seeds" to supermassive BHs. Recently Bogdan et al. (2023) reported the detection of…
X-ray metal line emission from the hot circumgalactic medium: probing the effects of supermassive black hole feedback
Nhut Truong, Annalisa Pillepich, Dylan Nelson +15
We derive predictions from state-of-the-art cosmological galaxy simulations for the spatial distribution of the hot circumgalactic medium (CGM, ) through its…
Painting baryons onto N-body simulations of galaxy clusters with image-to-image deep learning
Urmila Chadayammuri, Michelle Ntampaka, John ZuHone +2
Galaxy cluster mass functions are a function of cosmology, but mass is not a direct observable, and systematic errors abound in all its observable proxies. Mass-free inference can…
A high black hole to host mass ratio in a lensed AGN in the early Universe
Lukas J. Furtak, Ivo Labbé, Adi Zitrin +34
Early JWST observations have uncovered a new population of red sources that might represent a previously overlooked phase of supermassive black hole growth (Kocevski et al. 2023; M…
First Detection of an Over-Massive Black Hole Galaxy UHZ1: Evidence for Heavy Black Hole Seed Formation from Direct Collapse
Priyamvada Natarajan, Fabio Pacucci, Angelo Ricarte +3
The recent Chandra-JWST discovery of a quasar in the z = 10.1 galaxy UHZ1 reveals that accreting supermassive black holes (SMBHs) were already in place 470 million years after the…
Properties of the Line-of-Sight Velocity Field in the Hot and X-ray Emitting Circumgalactic Medium of Nearby Simulated Disk Galaxies
J. A. ZuHone, G. Schellenberger, A. Ogorzalek +16
The hot, X-ray-emitting phase of the circumgalactic medium of massive galaxies is believed to be the reservoir of baryons from which gas flows onto the central galaxy and into whic…
Resonant scattering of the OVII X-ray emission line in the circumgalactic medium of TNG50 galaxies
Dylan Nelson, Chris Byrohl, Anna Ogorzalek +15
We study the impact of resonantly scattered X-ray line emission on the observability of the hot circumgalactic medium (CGM) of galaxies. We apply a Monte Carlo radiative transfer p…
Circumgalactic Medium on the Largest Scales: Detecting X-ray Absorption Lines with Large-Area Microcalorimeters
Akos Bogdan, Ildar Khabibullin, Orsolya Kovacs +22
The circumgalactic medium (CGM) plays a crucial role in galaxy evolution as it fuels star formation, retains metals ejected from the galaxies, and hosts gas flows in and out of gal…
Evidence for heavy seed origin of early supermassive black holes from a z~10 X-ray quasar
Akos Bogdan, Andy Goulding, Priyamvada Natarajan +9
Observations of quasars reveal that many supermassive black holes (BHs) were in place less than 700 million years after the Big Bang. However, the origin of the first BHs remains a…
