Scientific paper

Interactions of high-density matter with rapidly rotating black holes are a natural outcome of core collapse in massive stars, neutron star mergers, or the coalescence of black hole-neutron star binaries. An ensuing long-lived state of suspended accretion may explain GRB 030329/SN 2003dh and GRB 060614. It predicts a chirp in gravitational radiation with exponential decaying frequency, by correlation of the radius of the surrounding matter with an expanding ISCO during viscous relaxation to a nearly Schwarzschild spacetime. The asymptotic value fgw (in kHz) provides novel metrology of the black hole mass M<=5.9f-1gw Msolar. An optimal search algorithm is included.
