Photoionized emission and absorption features in the high-resolution X-ray spectra of NGC 3783
Junjie Mao, M. Mehdipour, J. S. Kaastra +14
Our Swift monitoring program triggered two joint XMM-Newton, NuSTAR and HST observations on 11 and 21 December 2016 targeting NGC 3783, as its soft X-ray continuum was heavily obsc…
An X-ray spectroscopic search for dark matter and unidentified line signatures in the Perseus cluster with Hitomi
Takayuki Tamura, Andrew C. Fabian, Poshak Gandhi +14
We present results of a search for unidentified line emission and absorption signals in the 2-12keV energy band of spectra extracted from Perseus Cluster core region observations o…
NuSTAR reveals the hidden nature of SS433
M. J. Middleton, D. J. Walton, W. Alston +25
SS433 is the only Galactic binary system known to persistently accrete at highly super-critical (or hyper-critical) rates, similar to those in tidal disruption events, and likely n…
Detection of polarized gamma-ray emission from the Crab nebula with Hitomi Soft Gamma-ray Detector
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +191
We present the results from the Hitomi Soft Gamma-ray Detector (SGD) observation of the Crab nebula. The main part of SGD is a Compton camera, which in addition to being a spectrom…
Nitrogen abundance in the X-ray halos of clusters and groups of galaxies
Junjie Mao, J. de Plaa, J. S. Kaastra +6
Chemical abundances in the X-ray halos (also known as the intracluster medium, ICM) of clusters and groups of galaxies can be measured via prominent emission line features in their…
A stratified ultrafast outflow in 1H0707-495?
P. Kosec, D. J. K. Buisson, M. L. Parker +3
Ultrafast outflows (UFOs) have recently been found in the spectra of a number of active galactic nuclei (AGN) and are strong candidates for driving AGN feedback. 1H0707-495 is a hi…
