Photometric redshift of the GRB 981226 host galaxy

L. Christensen, J. Hjorth, J. Gorosabel

No optical afterglow was found for the dark burst GRB 981226 and hence no absorption redshift has been obtained. We here use ground-based and space imaging observations to analyse…

UV star-formation rates of GRB host galaxies

L. Christensen, J. Hjorth, J. Gorosabel

We study a magnitude-limited sample of 10 gamma-ray burst (GRB) host galaxies with known spectroscopic redshifts (0.43 < z < 2.04). From an analysis of the spectral energy distribu…

Gamma-Ray Bursts observed by XMM-Newton

P. T. O'Brien, J. N. Reeves, D. Watson +2

Analysis of observations with XMM-Newton have made a significant contribution to the study of Gamma-ray Burst (GRB) X-ray afterglows. The effective area, bandpass and resolution of…

Source Detection in Simulated XMM-Newton Observations

Jesper Rasmussen, Kristian Pedersen, Martin Gotz

We present preliminary results from our on-going study: Comparing and optimizing source detection procedures for XMM images. By constructing realistic spatial and spectral source d…

Chandra X-ray Observations of the Quadruply Lensed Quasar RX J0911.4+0551

Nicholas D. Morgan, George Chartas, Michael Malm +5

We present results from X-ray observations of the quadruply lensed quasar RX J0911.4+0551 using data obtained with the Advanced CCD Imaging Spectrometer (ACIS) on board the Chandra…

Spectroscopic confirmation of a cluster of galaxies at z=1 in the field of the gravitational lens MG2016+112

G. Soucail, J. P. Kneib, A. O. Jaunsen +3

We present new optical data on the cluster AX J2019+1127 identified by the X-ray satellite ASCA at z\sim 1 (Hattori et al. 1997). The data suggest the presence of a high-redshift c…
