Where is the matter in the Merging Cluster Abell 2218?
Árdís Elíasdóttir, Marceau Limousin, Johan Richard +6
We present a parametric strong lensing model of the cluster Abell 2218 based on HST ACS data. We constrain the lens model using 8 previously known multiply imaged systems, of which…
Hot GRB-selected Submillimeter Galaxies
M. J. Michałowski, J. Hjorth, J. M. Castro Cerón +1
Using detailed spectral energy distribution fits we present evidence that submillimeter- and radio-bright gamma-ray burst host galaxies are hotter counterparts to submillimeter gal…
Spectral energy distributions of submm/radio bright gamma-ray burst host galaxies
M. J. Michałowski, J. Hjorth
We present optical to radio spectral energy distribution fitting of the host galaxies of four long gamma-ray bursts: 980703, 000210, 000418 and 010222, which were detected at submi…
The nature of GRB-selected submillimeter galaxies: hot and young
M. J. Michałowski, J. Hjorth, J. M. Castro Cerón +1
We present detailed fits of the spectral energy distributions (SEDs) of four submillimeter (submm) galaxies selected by the presence of a gamma-ray burst (GRB) event (GRBs 980703,…
On the nature of the short duration GRB 050906
A. J. Levan, N. R. Tanvir, P. Jakobsson +12
We present deep optical and infrared observations of the short duration GRB 050906. Although no X-ray or optical/IR afterglow was discovered to deep limits, the error circle of the…
Spatially resolved properties of the GRB 060505 host: implications for the nature of the progenitor
Christina C. Thoene, Johan P. U. Fynbo, Goeran Oestlin +12
GRB 060505 was the first well-observed nearby possible long-duration GRB that had no associated supernova. Here we present spatially resolved spectra of the host galaxy of GRB 0605…
