A New Transient Ultraluminous X-ray Source in NGC 7090
D. J. Walton, M. Heida, M. Bachetti +17
We report on the discovery of a new, transient ultraluminous X-ray source (ULX) in the galaxy NGC 7090. This new ULX, which we refer to as NGC 7090 ULX3, was discovered via monitor…
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…
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…
Spectral evolution of the ultraluminous X-ray sources M82 X-1 and X-2
Murray Brightman, Dominic J. Walton, Yanjun Xu +5
M82 hosts two well-known ultraluminous X-ray sources (ULXs). X-1, an intermediate-mass black hole (IMBH) candidate, and X-2, an ultraluminous X-ray pulsar (ULXP). Here we present a…
