Tips and Tricks in linear imaging polarimetry of extended sources with FORS2 at the VLT
S. González-Gaitán, A. M. Mourão, F. Patat +5
Context: Polarimetry is a very powerful tool to uncover various properties of astronomical objects that remain otherwise hidden in standard imaging or spectroscopic observations. H…
Polarimetry of relativistic tidal disruption event Swift J2058+0516
K. Wiersema, A. B. Higgins, A. J. Levan +8
A small fraction of candidate tidal disruption events (TDEs) show evidence of powerful relativistic jets, which are particularly pronounced at radio wavelengths, and likely contrib…
Short GRB 160821B: a reverse shock, a refreshed shock, and a well-sampled kilonova
G. P. Lamb, N. R. Tanvir, A. J. Levan +31
We report our identification of the optical afterglow and host galaxy of the short-duration gamma-ray burst GRB 160821B. The spectroscopic redshift of the host is , making…
Detailed multi-wavelength modelling of the dark GRB 140713A and its host galaxy
A. B. Higgins, A. J. van der Horst, R. L. C. Starling +8
We investigate the afterglow of GRB 140713A, a gamma-ray burst (GRB) that was detected and relatively well-sampled at X-ray and radio wavelengths, but was not present at optical an…
Infrared molecular hydrogen lines in GRB host galaxies
K. Wiersema, A. Togi, D. Watson +12
Molecular species, most frequently H_2, are present in a small, but growing, number of gamma-ray burst (GRB) afterglow spectra at redshifts z~2-3, detected through their rest-frame…
Calibration of EFOSC2 broadband linear imaging polarimetry
K. Wiersema, A. B. Higgins, S. Covino +1
EFOSC2 (the European Southern Observatory Faint Object Spectrograph and Camera v2) is one of the workhorse instruments on ESO's New Technology Telescope (NTT), and is one of the mo…
