<i>CHANDRA</i> AND <i>SWIFT</i> FOLLOW-UP OBSERVATIONS OF THE INTERMEDIATE-MASS BLACK HOLE IN ESO 243-49
The brightest Ultra-Luminous X-ray source HLX-1 in the galaxy ESO 243-49 provides strong evidence for the existence of intermediate mass black holes. As the luminosity and thus the mass estimate depend on the association of HLX-1 with ESO 243-49, it is essential to confirm its affiliation. This requires follow-up investigations …
