Swift monitoring of the central X-ray source in RCW 103
pulsars: general – stars: neutron – X-rays: individual: 1E 161348–5055
2011/10/11
The X-ray source 1E 161348-5055 lies at the centre of the 2-kyr-old supernova remnant RCW 103. Owing to its 24-ks modulation, orders-of-magnitude flux variability over a few months/years, and lack of ...
Large-scale radio nebula around the Ultra-Luminous X-ray Source IC 342 X-1
Large-scale radio nebula the Ultra-Luminous X-ray Source IC 342 X-1
2011/1/10
We present discovery of a radio nebula associated with the ultraluminous X-ray source (ULX) IC 342 X-1 using the Very Large Array (VLA). Taking the surrounding nebula as a calorimeter, one can constra...
Discovery and follow-up studies of the extended, off-plane, VHE gamma-ray source HESS J1507-622
follow-up studies off-plane VHE gamma-ray source HESS J1507-622
2011/1/10
Context: The detection of gamma-rays in the very-high-energy (VHE) range (100 GeV-100 TeV) offers the possibility of studying the parent population of ultrarelativistic particles found in astrophysica...
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...
Exploring the Nature of the Brightest Hyper-luminous X-ray Source
accretion accretion disks – X-rays binaries – X-rays individual (ESO 243-49 HLX-1)
2010/11/11
The small subset of hyper-luminous X-ray sources with luminosities in excess of 1041 erg s−1 are hard to explain without the presence of an intermediate mass black hole, as significantly super-...
