Evolution of tidal disruption candidates discovered by XMM-Newton
P. Esquej, R. D. Saxton, S. Komossa +8
It has been demonstrated that active galactic nuclei are powered by gas accretion onto supermassive black holes located at their centres. The paradigm that the nuclei of inactive g…
Optical spectroscopy of Arp220: the star formation history of the closest ULIRG
J. Rodriguez Zaurin, C. N. Tadhunter, R. M. Gonzalez Delgado
We present optical spectra of the merging system Arp 220,taken with the William Herschel Telescope(WHT) on La Palma. These data were taken with the aim of investigating the evoluti…
A census of young stellar populations in the warm ULIRG PKS1345+12
J. Rodriguez Zaurin, J. Holt, C. N. Tadhunter +1
We present a detailed investigation of the young stellar populations(YSP) in the radio-loud ultra luminous infrared galaxy (ULIRG) PKS1345+12, based on high resolution HST imaging…
Gas and dust properties in the afterglow spectra of GRB 050730
R. L. C. Starling, P. M. Vreeswijk, S. L. Ellison +9
We present early WHT ISIS optical spectroscopy of the afterglow of gamma-ray burst GRB 050730. The spectrum shows a DLA system with the highest measured hydrogen column to date: N(…
