A bright gamma-ray flare interpreted as a giant magnetar flare in NGC 253
D. Svinkin, D. Frederiks, K. Hurley +33
Magnetars are young, highly magnetized neutron stars that produce extremely rare giant flares of gamma-rays, the most luminous astrophysical phenomena in our Galaxy. The detection…
GRB 161219B-SN 2016jca: a powerful stellar collapse
C. Ashall, P. A. Mazzali, E. Pian +26
We report observations and analysis of the nearby gamma-ray burst GRB\,161219B (redshift ) and the associated Type Ic supernova (SN) 2016jca. GRB\,161219B had an isotropi…
Broad-band study with Suzaku of the magnetar class
Teruaki Enoto, Kazuhiro Nakazawa, Kazuo Makishima +3
Broad-band (0.8-70 keV) spectra of the persistent X-ray emission from 9 magnetars were obtained with Suzaku, including 3 objects in apparent outburst. The soft X-ray component was…
GRB 090423 at a redshift of z~8.1
R. Salvaterra, M. Della Valle, S. Campana +42
Gamma-ray bursts (GRBSs) are produced by rare types of massive stellar explosions. Their rapidly fading afterglows are often bright enough at optical wavelengths, that they are det…
The Behavior of Matter under Extreme Conditions
F. Paerels, M. Mendez, M. Agueros +29
The cores of neutron stars harbor the highest matter densities known to occur in nature, up to several times the densities in atomic nuclei. Similarly, magnetic field strengths can…
GRB 050904 at redshift 6.3: observations of the oldest cosmic explosion after the Big Bang
G. Tagliaferri, L. A. Antonelli, G. Chincarini +10
We present optical and near-infrared observations of the afterglow of the gamma-ray burst GRB 050904. We derive a photometric redshift z = 6.3, estimated from the presence of the L…
