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…
Multi-Wavelength Studies of the Optically Dark Gamma-Ray Burst 001025A
K. Pedersen, K. Hurley, J. Hjorth +18
We identify the fading X-ray afterglow of GRB 001025A from XMM-Newton observations obtained 1.9-2.3 days, 2 years, and 2.5 years after the burst. The non-detection of an optical co…
Plasma Diagnostics of Active Region Evolution and Implications for Coronal Heating
R. O. Milligan, P. T. Gallagher, M. Mathioudakis +2
A detailed study is presented of the decaying solar active region NOAA 10103 observed with the Coronal Diagnostic Spectrometer (CDS), the Michelson Doppler Imager (MDI) and the Ext…
Outshining the quasars at reionisation: The X-ray spectrum and lightcurve of the redshift 6.29 Gamma-Ray Burst GRB050904
D. Watson, J. N. Reeves, J. Hjorth +7
Gamma-ray burst (GRB) 050904 is the most distant X-ray source known, at z=6.295, comparable to the farthest AGN and galaxies. Its X-ray flux decays, but not as a power-law; it is d…
The world problem: on the computability of the topology of 4-manifolds
James R. van Meter
Topological classification of the 4-manifolds bridges computation theory and physics. A proof of the undecidability of the homeomorphy problem for 4-manifolds is outlined here in a…
Climatic and Biogeochemical Effects of a Galactic Gamma-Ray Burst
Adrian L. Melott, Brian C. Thomas, Daniel P. Hogan +2
It is likely that one or more gamma-ray bursts within our galaxy have strongly irradiated the Earth in the last Gy. This produces significant atmospheric ionization and dissociatio…
