SMSS J130522.47-293113.0: a high-latitude stellar X-ray source with pc-scale outflow relics?
G. S. Da Costa, R. Soria, S. A. Farrell +17
We report the discovery of an unusual stellar system, SMSS J130522.47-293113.0. The optical spectrum is dominated by a blue continuum together with emission lines of hydrogen, neut…
Optical variability of the accretion disk around the intermediate mass black hole ESO 243-49 HLX-1 during the 2012 outburst
N. A. Webb, O. Godet, K. Wiersema +5
We present dedicated quasi-simultaneous X-ray (Swift) and optical (Very Large Telescope (VLT), V- and R-band) observations of the intermediate mass black hole candidate ESO 243-49…
Investigating slim disk solutions for HLX-1 in ESO 243-49
O. Godet, B. Plazolles, T. Kawaguchi +7
The hyper luminous X-ray source HLX-1 in the galaxy ESO 243-49, currently the best intermediate mass black hole candidate, displays spectral transitions similar to those observed i…
The X-ray Transient 2XMMi J003833.3+402133: A Candidate Magnetar at High Galactic Latitude
Joseph R. Callingham, Sean A. Farrell, Bryan M. Gaensler +2
We present detailed analysis of the transient X-ray source 2XMMi J003833.3+402133 detected by XMM-Newton in January 2008 during a survey of M 31. The X-ray spectrum is well fitted…
Further Observations of the Intermediate Mass Black Hole Candidate ESO 243-49 HLX-1
S. A. Farrell, M. Servillat, S. R. Oates +4
The brightest Ultra-Luminous X-ray source HLX-1 in the galaxy ESO 243-49 currently provides strong evidence for the existence of intermediate mass black holes. Here we present the…
