Ultraluminous X-ray source 1E 0953.8+6918 (M81 X-9): an intermediate-mass black hole candidate and its environs
binaries bubbles
2014/12/26
We present a ROSAT and ASCA study of the Einstein source X-9 and its relation to a shock-heated shell-like optical nebula in a tidal arm of the M81 group of interacting galaxies. Our ASCA observation ...
Nonnuclear Hyper/Ultraluminous X-Ray Sources in the Starbursting Cartwheel Ring Galaxy
VV 784 Cartwheel
2014/12/24
We report the Chandra/ACIS-S detection of more than 20 ultraluminous X-ray sources (ULXs; L0.5-10 keV 3 × 1039 ergs s-1) in the Cartwheel collisional ring galaxy system, of which over a dozen are loca...
An Optical Study of Stellar and Interstellar Environments of Seven Luminous and Ultraluminous X-Ray Sources
M81 NGC 1313
2014/12/24
We have studied the stellar and interstellar environments of two luminous X-ray sources and five ultraluminous X-ray sources (ULXs) in order to gain insight into their nature. Archival Hubble Space Te...
A Large Catalogue of Ultraluminous X-ray Source Candidates in Nearby Galaxies
X-rays binaries black hole physics
2010/11/9
Since their discovery, Ultraluminous X-ray sources (ULXs) have attracted attention due to their combination of extreme luminosities and extra-nuclear locations. However, they are a fairly rare phenome...
Optical variability of the ultraluminous X-ray source NGC 1313 X-2
stars individual (NGC 1313 X-2) – X-rays binaries – X-rays individuals (NGC 1313 X-2)
2010/11/12
We analyzed the longest phase-connected photometric dataset available for NGC 1313 X-2,looking for the 6 day modulation reported by Liu et al. (2009). The folded B band light curve shows a 6 days per...
