Isolating Sgr A East: The First Uncontaminated X-ray Maps of a Galactic Center Supernova Remnant
Mayura Balakrishnan, Adrien Picquenot, Lia Corales +3
The central few parsecs of the Milky Way host a complex X-ray-emitting environment in which several extended plasma components are blended along the line of sight, complicating att…
Candidate intermediate-mass black hole discovered in an extremely young low-metallicity cluster in the tadpole galaxy KUG 1138+327
Q. Daniel Wang, Juergen Ott
We explore what unusual products a starburst of about 6% solar metallicity and a mean estimated age of ~0.5 Myr can produce in KUG 1138 + 327 at a distance of 24.5 Mpc. Chandra X-r…
Overionized plasma in the supernova remnant Sagittarius A East anchored by XRISM observations
XRISM Collaboration
Sagittarius A East is a supernova remnant with a unique surrounding environment, as it is located in the immediate vicinity of the supermassive black hole at the Galactic center, S…
Multistructured accretion flow of Sgr A* II: Signatures of a Cool Accretion Disk in Hydrodynamic Simulations of Stellar Winds
Mayura Balakrishnan, Christopher M. P. Russell, Lia Corrales +8
Hydrodynamic simulations of the stellar winds from Wolf-Rayet stars within the Galactic Center can provide predictions for the X-ray spectrum of supermassive black hole Sgr A*. Her…
Multistructured accretion flow of Sgr A* I: Examination of a RIAF model
Mayura Balakrishnan, Lia Corrales, Sera Markoff +8
The extreme low-luminosity supermassive black hole Sgr A* provides a unique laboratory in which to test radiatively inefficient accretion flow (RIAF) models. Previous fits to the q…
Spectral Energy Distribution of the inner accretion flow around Sgr A* -- Clue for a weak outflow in the innermost region
Ren-Yi Ma, Shawn R. Roberts, Ya-Ping Li +1
Sgr A* represents a unique laboratory for the detailed study of accretion processes around a low-luminosity supermassive black hole (SMBH). Recent X-ray observations have allowed f…
Modelling the thermal X-ray emission around the Galactic centre from colliding Wolf-Rayet winds
Christopher M. P. Russell, Q. Daniel Wang, Jorge Cuadra
The Galactic centre is a hotbed of astrophysical activity, with the injection of wind material from 30 massive Wolf-Rayet (WR) stars orbiting within 12" of the super-massive…
Modelling the thermal X-ray emission around the Galactic Centre from colliding Wolf-Rayet winds
Christopher M. P. Russell, Q. Daniel Wang, Jorge Cuadra
The Galactic Centre is a hotbed of astrophysical activity, with the injection of wind material from 30 massive Wolf-Rayet (WR) stars orbiting within 12 arcsec of the supermas…
Confronting the jet model of Sgr A* with the Faraday rotation measure observations
Ya-Ping Li, Feng Yuan, Q. Daniel Wang
Sgr A* is probably the supermassive black hole being investigated most extensively due to its proximity. Several theoretical models for its steady state emission have been proposed…
