Detection of the low-frequency QPOs in MAXI J1535-571
Abstract
During current (on September 11, 2007) Swift-XRT observations of the new black hole transient MAXI J1535-571 (ATel #10699) we detected a strong peak of QPOs at 1.9 Hz. Last days the source demonstrated spectral softening (ATel #10729, #10731), indicating the beginning of a transition between the hard and soft states.
