AstroSat Observations of the first Galactic ULX Pulsar Swift J0243.6+6124
Aru Beri, Sachindra Naik, K. P Singh +11
SwiftJ0243.6+6124, the first Galactic ultra-luminous X-ray pulsar, was observed during its 2017-2018 outburst with \emph{AstroSat} at both sub- and super-Eddington levels of accret…
The (re)appearance of NGC 925 ULX-3, a new transient ULX
Hannah P. Earnshaw, Marianne Heida, Murray Brightman +8
We report the discovery of a third ULX in NGC 925 (ULX-3), detected in November 2017 by Chandra at a luminosity of erg s. Examination…
Blueshifted absorption lines from X-ray reflection in IRAS 13224-3809
A. C. Fabian, C. S. Reynolds, J. Jiang +17
We explore a disc origin for the highly-blueshifted, variable absorption lines seen in the X-ray spectrum of the Narrow Line Seyfert 1 galaxy IRAS13224-3809. The blueshift correspo…
The Ultraluminous X-ray sources population of the galaxy NGC 7456
F. Pintore, M. Marelli, R. Salvaterra +28
Ultraluminous X-ray sources (ULXs) are a class of accreting compact objects with X-ray luminosities above 1e39 erg/s. The ULX population counts several hundreds objects but only a…
A dynamic black hole corona in an active galaxy through X-ray reverberation mapping
William N. Alston, Andrew C. Fabian, Erin Kara +18
X-ray reverberation echoes are assumed to be produced in the strongly distorted spacetime around accreting supermassive black holes. This signal allows us to spatially map the geom…
