PHL 1092 as a transient extreme X-ray weak quasar
G. Miniutti, A. C. Fabian, W. N. Brandt +2
We report a dramatic variability event in the X-ray history of the Narrow-Line quasar PHL 1092 (z=0.396). Our latest 2008 XMM-Newton observation reveals a flux drop of ~200 with re…
A submillimetre galaxy at z=4.76 in the LABOCA survey of the Extended Chandra Deep Field South
Kristen Coppin, Ian Smail, David M. Alexander +30
We report on the identification of the highest redshift submm-selected source currently known: LESSJ033229.4-275619. This source was detected in the Large Apex BOlometer CAmera (LA…
Two distant brown dwarfs in the UKIRT Infrared Deep Sky Survey Deep Extragalactic Survey Data Release 2
N. Lodieu, P. D. Dobbie, N. R. Deacon +2
We present the discovery of two brown dwarfs in the UKIRT Infrared Deep Sky Survey (UKIDSS) Deep Extragalactic Survey (DXS) Data Release 2. Both objects were selected photometrical…
GPUs for data processing in the MWA
S. Ord, L. Greenhill, R. Wayth +4
The MWA is a next-generation radio interferometer under construction in remote Western Australia. The data rate from the correlator makes storing the raw data infeasible, so the da…
XMM-Newton and Suzaku analysis of the Fe K complex in the Seyfert 1 galaxy Mrk 509
G. Ponti, M. Cappi, C. Vignali +11
We report on partially overlapping XMM-Newton (~260 ks) and Suzaku (~100 ks) observations of the iron K band in the nearby, bright Seyfert 1 galaxy Mrk 509. The source shows a reso…
