GRB060602B = Swift J1749.4-2807: an unusual transiently accreting neutron-star X-ray binary
Rudy Wijnands, Evert Rol, Ed M. Cackett +2
We present an analysis of the Swift BAT and XRT data of GRB060602B, which is most likely an accreting neutron star in a binary system and not a gamma-ray burst. Our analysis shows…
Relativistic iron emission lines in neutron star low-mass X-ray binaries as probes of neutron star radii
Edward M. Cackett, Jon M. Miller, Sudip Bhattacharyya +6
Using Suzaku observations of three neutron star low-mass X-ray binaries (Ser X-1, 4U 1820-30 and GX 349+2) we have found broad, asymmetric, relativistic Fe K emission lines in all…
Testing thermal reprocessing in AGN accretion discs
E. M. Cackett, K. Horne, H. Winkler
The thermal reprocessing hypothesis in AGN, where EUV/X-ray photons are reprocessed by the accretion disc into optical/UV photons, predicts wavelength-dependent time delays between…
NGC 5548 in a Low-Luminosity State: Implications for the Broad-Line Region
Misty C. Bentz, Kelly D. Denney, Edward M. Cackett +15
We describe results from a new ground-based monitoring campaign on NGC 5548, the best studied reverberation-mapped AGN. We find that it was in the lowest luminosity state yet recor…
