Suzaku Observations of Active Galactic Nuclei Detected in the Swift/BAT Survey: Discovery of "New Type" of Buried Supermassive Black Holes
Yoshihiro Ueda, Satoshi Eguchi, Yuichi Terashima +6
We present the Suzaku broad band observations of two AGNs detected by the Swift/BAT hard X-ray (>15 keV) survey that did not have previous X-ray data, Swift J0601.9-8636 and Swift…
Outbursts of EX Hydrae Revisited
N. Mhlahlo, D. A. H. Buckley, V. Dhillon +3
We present optical spectroscopy of EX Hya during its 1991 outburst. This outburst is characterised by strong irradiation of the front face of the secondary star by the white dwarf,…
The Discovery of a Persistent Quasi-Periodic Oscillation in the Intermediate Polar TX Col
N. Mhlahlo, D. A. H. Buckley, V. S. Dhillon +8
We report on the detection of an ~5900 s quasi-periodic variation in the extensive photometry of TX Col spanning 12 years. We discuss five different models to explain this period.…
Observational Constraints on Interstellar Grain Alignment
B-G Andersson, S. B. Potter
We present new multicolor photo-polarimetry of stars behind the Southern Coalsack. Analyzed together with multiband polarization data from the literature, probing the Chamaeleon I,…
Spectroscopic Observations of the Intermediate Polar EX Hydrae in Quiescence
Nceba Mhlahlo, David H. Buckley, Vikram S. Dhillon +3
Results from spectroscopic observations of the Intermediate Polar (IP) EX Hya in quiescence during 1991 and 2001 are presented. Spin-modulated radial velocities consistent with an…
Recent observational progress in AM CVn binaries
G. Ramsay, C. Brocksopp, P. Groot +9
We present the results of some recent research on AM CVn systems. We present: X-ray/UV observations made using XMM-Newton; the X-ray grating spectrum of RX J1914+24; preliminary re…
