As suggested by optical observations, the globular cluster NGC 6388 may harbor a central intermediate-mass black hole with mass of about 5.7 × 103 M⊙. We review the past X-ray and radio observations conducted towards NGC 6388 with particular attention to IGRJ17361-4441, i.e. a high energy transient recently discovered by using the INTEGRAL satellite.

Abstract
As suggested by optical observations, the globular cluster NGC 6388 may harbor a central intermediate-mass black hole with mass of about 5.7 × 103 M⊙. We review the past X-ray and radio observations conducted towards NGC 6388 with particular attention to IGRJ17361-4441, i.e. a high energy transient recently discovered by using the INTEGRAL satellite. The transient was located at the globular cluster center thus leaving the intriguing possibility that it may be associated to the central black hole activity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
