GRBAlpha: A 1U CubeSat mission for validating timing-based gamma-ray burst localization
András Pál, Masanori Ohno, László Mészáros +26
GRBAlpha is a 1U CubeSat mission with an expected launch date in the first half of 2021. It carries a 75 x 75 x 5 mm CsI(Tl) scintillator, read out by a dual-channel multi-pixel ph…
Correlations between supermassive black holes and hot gas atmospheres in IllustrisTNG and X-ray observations
Nhut Truong, Annalisa Pillepich, Norbert Werner
Recent X-ray observations have revealed remarkable correlations between the masses of central supermassive black holes (SMBHs) and the X-ray properties of the hot atmospheres perme…
Hot gaseous atmospheres of rotating galaxies observed with XMM-Newton
A. Juráňová, N. Werner, P. E. J. Nulsen +6
X-ray emitting atmospheres of non-rotating early-type galaxies and their connection to central active galactic nuclei have been thoroughly studied over the years. However, in syste…
Multiwavelength classification of X-ray selected galaxy cluster candidates using convolutional neural networks
Matej Kosiba, Maggie Lieu, Bruno Altieri +15
Galaxy clusters appear as extended sources in XMM-Newton images, but not all extended sources are clusters. So, their proper classification requires visual inspection with optical…
Properties of the Hot Ambient Medium of Early-type Galaxies Hosting Powerful Radio Sources
Rachel L. S. Frisbie, Megan Donahue, G. Mark Voit +6
We present an archival analysis of Chandra X-ray observations for twelve nearby early-type galaxies hosting radio sources with radio power at 1.4…
X-ray spectra of the Fe-L complex II: atomic data constraints from EBIT experiment and X-ray grating observations of Capella
Liyi Gu, Chintan Shah, Junjie Mao +14
The Hitomi results for the Perseus cluster have shown that accurate atomic models are essential to the success of X-ray spectroscopic missions, and just as important as knowledge o…
