HI study of the environment around ESO 243-49, the host galaxy of an intermediate mass black hole
A. Musaeva, B. S. Koribalski, S. A. Farrell +9
The lenticular galaxy ESO 243-49 hosts the ultraluminous X-ray source HLX-1, the best candidate intermediate mass black hole (IMBH) currently known. The environments of IMBHs remai…
NuSTAR and XMM-Newton observations of the extreme ultraluminous X-ray source NGC 5907 ULX1: A Vanishing Act
D. J. Walton, F. A. Harrison, M. Bachetti +15
We present results obtained from two broadband X-ray observations of the extreme ultraluminous X-ray source (ULX) NGC5907 ULX1, known to have a peak X-ray luminosity of ~5e40 erg/s…
On the radio properties of the intermediate-mass black hole candidate ESO 243-49 HLX-1
D. Cseh, N. A. Webb, O. Godet +8
We present follow-up radio observations of ESO 243-49 HLX-1 from 2012 using the Australia Telescope Compact Array (ATCA) and the Karl G. Jansky Very Large Array (VLA). We report th…
An Ultraluminous X-ray Source Powered by An Accreting Neutron Star
M. Bachetti, F. A. Harrison, D. J. Walton +21
Ultraluminous X-ray sources (ULX) are off-nuclear point sources in nearby galaxies whose X-ray luminosity exceeds the theoretical maximum for spherical infall (the Eddington limit)…
No Time for Dead Time: Timing analysis of bright black hole binaries with NuSTAR
Matteo Bachetti, Fiona A. Harrison, Rick Cook +20
Timing of high-count rate sources with the NuSTAR Small Explorer Mission requires specialized analysis techniques. NuSTAR was primarily designed for spectroscopic observations of s…
Broadband X-ray Spectra of the Ultraluminous X-ray Source Holmberg IX X-1 observed with NuSTAR, XMM-Newton and Suzaku
D. J. Walton, F. A. Harrison, B. W. Grefenstette +16
We present results from the coordinated broadband X-ray observations of the extreme ultraluminous X-ray source Holmberg IX X-1 performed by NuSTAR, XMM-Newton and Suzaku in late 20…
