Searching for the Highest-z Dual AGN in the Deepest Chandra Surveys
Brandon Sandoval, Adi Foord, Steven W. Allen +9
We present an analysis searching for dual AGN among 62 high-redshift () X-ray sources selected from publicly available deep Chandra fields. We aim to quantify the fr…
Hot Gas Outflow Properties of the Starburst Galaxy NGC 4945
Natalia Porraz Barrera, Sebastian Lopez, Laura A. Lopez +5
We analyze 330 ks of {\it Chandra} X-ray imaging and spectra of the nearby, edge-on starburst and Seyfert Type 2 galaxy NGC 4945 to measure the hot gas properties along the galacti…
AGN in overdense environments at high- with AXIS
Fabio Vito, Paolo Tozzi, Roberto Gilli +3
Overdense regions at high redshift () are perfect laboratories to study the relations between environment and SMBH growth, and the AGN feedback processes on the surrou…
Uncovering the First AGN Jets with AXIS
Thomas Connor, Eduardo Bañados, Nico Cappelluti +1
Jets powered by AGN in the early Universe () have the potential to not only define the trajectories of the first-forming massive galaxies but to enable the accelerated…
Detecting Wandering Intermediate-Mass Black Holes with AXIS in the Milky Way and Local Massive Galaxies
Fabio Pacucci, Bryan Seepaul, Yueying Ni +2
This white paper explores the detectability of intermediate-mass black holes (IMBHs) wandering in the Milky Way (MW) and massive local galaxies, with a particular emphasis on the r…
Prospects for AGN Studies with AXIS: AGN Fueling -- Resolving Hot Gas inside Bondi Radius of SMBHs
Ka-Wah Wong, Helen Russell, Jimmy Irwin +2
Hot gas around a supermassive black hole (SMBH) should be captured within the gravitational "sphere of influence", characterized by the Bondi radius. Deep Chandra observations have…
X-ray Redshifts for Obscured Active Galactic Nuclei with AXIS Deep and Intermediate Surveys
Alessandro Peca, Nico Cappelluti, Stefano Marchesi +2
This study presents the capabilities of the AXIS telescope in estimating redshifts from X-ray spectra alone (X-ray redshifts, XZs). Through extensive simulations, we establish that…
Surveying the onset and evolution of supermassive black holes at high-z with AXIS
Nico Cappelluti, Adi Foord, Stefano Marchesi +8
The nature and origin of supermassive black holes (SMBHs) remain an open matter of debate within the scientific community. While various theoretical scenarios have been proposed, e…
Tracking Supermassive Black Hole Mergers from kpc to sub-pc Scales with AXIS
Adi Foord, Nico Cappelluti, Tingting Liu +8
We present an analysis showcasing how the Advanced X-ray Imaging Satellite (AXIS), a proposed NASA Probe-class mission, will significantly increase our understanding of supermassiv…
