Swift follow-up observations of unclassified ASCA sources
N. Degenaar, R. L. C. Starling, P. A. Evans +11
We present Swift follow-up observations of a sample of 35 unclassified faint X-ray sources drawn from the ASCA Galactic centre and plane surveys. Our short pointed XRT observations…
Relativistic iron K X-ray Reverberation in NGC 4151
A. Zoghbi, A. C. Fabian, C. S. Reynolds +1
Recent X-ray observations have enabled the study of reverberation delays in AGN for the first time. All the detections so far are in sources with a strong soft excess, and the meas…
Identifying a new intermediate-polar using XMM-Newton and INTEGRAL
Matthew J. Middleton, Edward M. Cackett, Craig Shaw +3
The bright X-ray source, 2XMMi J180438.7-145647 is fortunate to have long baseline observations in INTEGRAL that compliment observations taken by other missions. Optical spectrosco…
A Fast X-ray Disk Wind in the Transient Pulsar IGR J17480-2446 in Terzan 5
Jon M. Miller, Dipankar Maitra, Edward M. Cackett +2
Accretion disk winds are revealed in Chandra gratings spectra of black holes. The winds are hot and highly ionized (typically composed of He-like and H-like charge states), and sho…
Quiescent X-ray variability from the neutron star transient Aql X-1
E. M. Cackett, J. K. Fridriksson, J. Homan +2
A number of studies have revealed variability from neutron star low-mass X-ray binaries during quiescence. Such variability is not well characterised, or understood, but may be a c…
A Distinctive Disk-Jet Coupling in the Seyfert-1 AGN NGC 4051
Ashley L. King, Jon M. Miller, Edward M. Cackett +6
We report on the results of a simultaneous monitoring campaign employing eight Chandra X-ray (0.5-10 keV) and six VLA/EVLA (8.4 GHz) radio observations of NGC 4051 over seven month…
