X-ray Detected AGN in SDSS Dwarf Galaxies
Keir L Birchall, M G Watson, J Aird
In this work we present a robust quantification of X-ray selected AGN in local () dwarf galaxies (). We define a pare…
The nature of the cataclysmic variable PT Per
Mike Watson, Alastair Bruce, Chelsea MacLeod +1
We present a study of the cataclysmic variable star PT Per based on archival XMM-Newton X-ray data and new optical spectroscopy from the WHT with ISIS. The X-ray data show deep min…
Exploring the Active Galactic Nuclei population with extreme X-ray to optical flux ratios (Fx/Fo >50)
R. Della Ceca, F. J. Carrera, A. Caccianiga +8
The cosmic history of the growth of supermassive black holes in galactic centers parallels that of star-formation in the Universe. However, an important fraction of this growth occ…
The soft X-ray blast in the apparently sub-luminous GRB 031203
D. Watson, S. A. Vaughan, R. Willingale +11
GRB031203 was a very low apparent luminosity gamma-ray burst (GRB). It was also the first GRB with a dust-scattered X-ray halo. The observation of the halo allowed us to infer the…
The SCUBA HAlf Degree Extragalactic Survey (SHADES) -- I. Survey motivation, design and data processing
A. M. J. Mortier, S. Serjeant, J. S. Dunlop +2
The SCUBA HAlf Degree Extragalactic Survey (SHADES) is a major blank-field extragalactic sub-mm survey underway at the James Clerk Maxwell telescope.SHADES aims to cover half a squ…
The central region of M31 observed with XMM-Newton. II. Variability of the individual sources
J. P. Osborne, K. N. Borozdin, S. P. Trudolyubov +13
We present the results of a study of the variability of X-ray sources in the central 30' of the nearby Andromeda Galaxy (M31) based on XMM Performance Verification observations. Tw…
