Protostellar mergers in protoclusters and the origin of ultra-luminous X-ray sources
R. Soria
I suggest that stellar coalescence in mid-size protoclusters (M ~ 10^{3.5} - 10^{4.5} M_sun) is a possible scenario for the formation of ultra-luminous X-ray sources (ULXs). More m…

Optical and Infrared Signatures of ULX's
Christopher Copperwheat, Mark Cropper, Roberto Soria +1
We have constructed a model to describe the optical emission from ultra-luminous X-ray sources (ULXs). We assume a binary model with a black hole accreting matter from a Roche lobe…

Runaway core collapse and cluster survival: where are the parent clusters of ULXs?
Roberto Soria
Accreting intermediate-mass black holes (IMBHs) have been proposed as an explanation for ultraluminous X-ray sources (ULXs). Runaway core collapse inside a massive cluster is a pos…
