Radio Emission from an Ultraluminous X-Ray Source [PDF]

open access: yes, 2003
The physical nature of ultraluminous x-ray sources is uncertain. Stellar mass black holes with beamed radiation and intermediate mass black holes with isotropic radiation are two plausible explanations.

A Comparison of Intermediate Mass Black Hole Candidate ULXs and Stellar-Mass Black Holes [PDF]

open access: yes, 2004
Cool thermal emission components have recently been revealed in the X-ray spectra of a small number of ultra-luminous X-ray (ULX) sources with L_X > 1 E+40 erg/s in nearby galaxies.

Intermediate-Mass Black Hole Candidate ULXs [PDF]

open access: yesProceedings of the International Astronomical Union, 2005
In a subset of the most luminous of the so-called “ultra-luminous” X-ray sources in nearby galaxies, there is evidence for black holes with masses considerably higher than found in Galactic binaries. Apart from extremely high X-ray luminosities, cool disks found in the X-ray spectra of these sources and X-ray timing measurements form the basis for ...

Prospects for measuring supermassive black hole masses with future extremely large telescopes [PDF]

open access: yes, 2014
The next generation of giant-segmented mirror telescopes ($>$ 20 m) will enable us to observe galactic nuclei at much higher angular resolution and sensitivity than ever before. These capabilities will introduce a revolutionary shift in our understanding

Intermediate-mass black holes in binary-rich star clusters [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
AbstractThree-body interactions of stellar-mass binaries with intermediate mass black holes (IMBHs) in nuclei of globular clusters may produce specific features that may serve as an independent indicator of existence of the IMBHs. By means of direct N-body integrations we follow the dynamical evolution of globular clusters of moderate extension and ...

Intermediate Mass Black Holes: Their Motion and Associated Energetics

open access: yesAdvances in High Energy Physics, 2014
There is a lot of current astrophysical evidence and interest in intermediate mass black holes (IMBH), ranging from a few hundred to several thousand solar masses.
