Four GRB-Supernovae at Redshifts between 0.4 and 0.8
S. Klose, S. Schmidl, D. A. Kann +16
Twenty years ago, GRB 980425/SN 1998bw revealed that long Gamma-Ray Bursts (GRBs) are physically associated with broad-lined type Ic supernovae. Since then more than 1000 long GRBs…
Census of HII regions in NGC 6754 derived with MUSE: Constraints on the metal mixing scale
S. F. Sánchez, L. Galbany, E. Pérez +11
We present a study of the HII regions in the galaxy NGC 6754 from a two pointing mosaic comprising 197,637 individual spectra, using Integral Field Spectrocopy (IFS) recently acqui…
Constraining supernova progenitors: an integral field spectroscopic survey of the explosion sites
H. Kuncarayakti, G. Aldering, J. P. Anderson +9
We describe a survey of nearby core-collapse supernova (SN) explosion sites using integral field spectroscopy (IFS) technique, which is an extension of the work described in Kuncar…
Dust extinction for an unbiased sample of GRB afterglows
S. Covino, A. Melandri, R. Salvaterra +15
In this paper we compute rest-frame extinctions for the afterglows of a sample of gamma-ray bursts complete in redshift. The selection criteria of the sample are based on observati…
GRB 091029: At the limit of the fireball scenario
R. Filgas, J. Greiner, P. Schady +20
Using high-quality, broad-band afterglow data for GRB 091029, we test the validity of the forward-shock model for gamma-ray burst afterglows. We used multi-wavelength (NIR to X-ray…
The structure and emission model of the relativistic jet in the quasar 3C 279 inferred from radio to high-energy gamma-ray observations in 2008-2010
M. Hayashida, G. M. Madejski, K. Nalewajko +90
We present time-resolved broad-band observations of the quasar 3C 279 obtained from multi-wavelength campaigns conducted during the first two years of the Fermi Gamma-ray Space Tel…
Detailed optical and near-infrared polarimetry, spectroscopy and broadband photometry of the afterglow of GRB 091018: Polarisation evolution
K. Wiersema, P. A. Curran, T. Kruehler +30
[Abridged] A number of phenomena have been observed in GRB afterglows that defy explanation by simple versions of the standard fireball model, leading to a variety of new models. P…
BL Lacertae objects beyond redshift 1.3 - UV-to-NIR photometry and photometric redshift for Fermi/LAT blazars
Arne Rau, P. Schady, J. Greiner +17
Observations of the gamma-ray sky with Fermi led to significant advances towards understanding blazars, the most extreme class of Active Galactic Nuclei. A large fraction of the po…
GRB 091127: The cooling break race on magnetic fuel
Robert Filgas, Jochen Greiner, Patricia Schady +13
Using high-quality, broad-band afterglow data for GRB 091127, we investigate the validity of the synchrotron fireball model for gamma-ray bursts, and infer physical parameters of t…
The two-component jet of GRB 080413B
R. Filgas, T. Kruehler, J. Greiner +16
The quick and precise localization of GRBs by the Swift telescope allows the early evolution of the afterglow light curve to be captured by ground-based telescopes. With GROND meas…
