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…
Towards Self-Consistent Modelling of the Sgr A* Accretion Flow: Linking Theory and Observation
Shawn R. Roberts, Yan-Fei Jiang, Q. Daniel Wang +1
The interplay between supermassive black holes (SMBHs) and their environments is believed to command an essential role in galaxy evolution. The majority of these SMBHs are in the r…
X-ray Emission from Charge Exchange in the Cygnus Loop SNR
Shawn R. Roberts, Q. Daniel Wang
The Cygnus Loop has been the focus of substantial debate concerning the contribution of charge exchange (CX) to supernova remnant (SNR) X-ray emission. We take advantage of a disti…
