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…
String rewriting for Double Coset Systems
Ronald Brown, Neil Ghani, Anne Heyworth +1
In this paper we show how string rewriting methods can be applied to give a new method of computing double cosets. Previous methods for double cosets were enumerative and thus rest…
Gamma-Ray Burst Selected High Redshift Galaxies: Comparison to Field Galaxy Populations to z~3
C. J. Conselice, P. M. Vreeswijk, A. S. Fruchter +6
We study the internal structural properties of 37 long duration gamma-ray burst (GRB) host galaxies imaged with the Hubble Space Telescope. Fitting exponential disk and r^1/4 model…
The XMM-Newton Slew Survey
A. M. Read, R. D. Saxton, M. P. Esquej +2
XMM-Newton, with the huge collecting area of its mirrors and the high quantum efficiency of its EPIC detectors, is the most sensitive X-ray observatory ever flown. This is striking…
Exploring X-ray emission and absorption in AGN with XMM-Newton EPIC
Ken Pounds
Broad band X-ray spectra of high statistical quality obtained with the EPIC instruments on XMM-Newton are being used to address key issues in AGN Physics, including the evidence fo…
Quadratic envelope of the category of class two nilpotent groups
Mamuka Jibladze, Teimuraz Pirashvili
We exhibit an extension of the category of class two nilpotent groups. It has the same objects but, unlike the latter, its morphisms are closed under pointwise addition of maps. At…
