A search for disk-galaxy lenses in the Sloan Digital Sky Survey
Chloé Féron, Jens Hjorth, John P. McKean +1
We present the first automated spectroscopic search for disk-galaxy lenses, using the Sloan Digital Sky Survey database. We follow up eight gravitational lens candidates, selected…
Simulated Dark-Matter Halos as a Test of Nonextensive Statistical Mechanics
Chloé Féron, Jens Hjorth
In the framework of nonextensive statistical mechanics, the equilibrium structures of astrophysical self-gravitating systems are stellar polytropes, parameterized by the polytropic…
A Search for Host Galaxies of 24 Gamma-Ray Bursts
J. -E. Ovaldsen, A. O. Jaunsen, J. P. U. Fynbo +6
We report the results from observations of 24 gamma ray burst (GRB) fields from 2005 and 2006 undertaken at the Danish 1.54m telescope at ESO/La Silla. Photometry and positions for…
The nature of the X-Ray Flash of August 24 2005
J. Sollerman, J. P. U. Fynbo, J. Gorosabel +23
We present comprehensive photometric R-band observations of the fading optical afterglow of the X-Ray Flash XRF050824, from 11 minutes to 104 days after the burst. The R-band light…
The Peculiar Type Ia Supernova 2005hk
V. Stanishev, S. Taubenberger, G. Blanc +15
We present a preliminary analysis of an extensive set of optical observations of the Type Ia SN 2005hk. We show that the evolution of SN 2005hk closely follows that of the peculiar…
Supernova 2006aj and the associated X-Ray Flash 060218
J. Sollerman, A. O. Jaunsen, J. P. U. Fynbo +23
We have studied the afterglow of the gamma-ray burst (GRB) of February 18, 2006. This is a nearby long GRB, with a very low peak energy, and is therefore classified as an X-ray Fla…
