X-ray Variability and Hardness of ESO 243-49 HLX-1: Clear Evidence for Spectral State Transitions
Mathieu Servillat, Sean A. Farrell, Dacheng Lin +3
The ultra-luminous X-ray (ULX) source ESO 243-49 HLX-1 currently provides the strongest evidence for the existence of intermediate mass black holes. We conduct an ongoing monitorin…
Toward an optimal search strategy of optical and gravitational wave emissions from binary neutron star coalescence
D. M. Coward, B. Gendre, P. J. Sutton +6
Observations of an optical source coincident with gravitational wave emission detected from a binary neutron star coalescence will improve the confidence of detection, provide host…
The Cool Accretion Disk in ESO 243-49 HLX-1: Further Evidence of an Intermediate Mass Black Hole
Shane W. Davis, Ramesh Narayan, Yucong Zhu +5
With an inferred bolometric luminosity exceeding 10^42 erg/s, HLX-1 in ESO 243-49 is the most luminous of ultraluminous X-ray sources and provides one of the strongest cases for th…
The origin of variability of the intermediate-mass black-hole ULX system HLX-1 in ESO 243-49
J. -P. Lasota, T. Alexander, G. Dubus +5
The ultra-luminous intermediate-mass black-hole system HLX-1 in the ESO 243-49 galaxy exhibits variability with a possible recurrence time of a few hundred days. Finding the origin…
