Suborbital Fermi/LAT Analysis of the Brightest Gamma-Ray Flare of Blazar 3C 454.3
Krzysztof Nalewajko
Recent detection of suborbital gamma-ray variability of Flat Spectrum Radio Quasar (FSRQ) 3C 279 by Fermi Large Area Telescope (LAT) is in severe conflict with established models o…
On the Progenitor of Binary Neutron Star Merger GW170817
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1095
On 2017 August 17 the merger of two compact objects with masses consistent with two neutron stars was discovered through gravitational-wave (GW170817), gamma-ray (GRB 170817A), and…
TeV gamma-ray observations of the binary neutron star merger GW170817 with H.E.S.S
H. E. S. S. Collaboration, :, H. Abdalla +250
We search for high-energy gamma-ray emission from the binary neutron star merger GW170817 with the H.E.S.S. Imaging Air Cherenkov Telescopes. The observations presented here have b…
GW170608: Observation of a 19-solar-mass Binary Black Hole Coalescence
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1101
On June 8, 2017 at 02:01:16.49 UTC, a gravitational-wave signal from the merger of two stellar-mass black holes was observed by the two Advanced LIGO detectors with a network signa…
A Model of Polarisation Rotations in Blazars from Kink Instabilities in Relativistic Jets
Krzysztof Nalewajko
This paper presents a simple model of polarisation rotation in optically thin relativistic jets of blazars. The model is based on the development of helical (kink) mode of current-…
Gravitational Waves and Gamma-rays from a Binary Neutron Star Merger: GW170817 and GRB 170817A
LIGO Scientific Collaboration, Virgo Collaboration, Fermi Gamma-Ray Burst Monitor +1
On 2017 August 17, the gravitational-wave event GW170817 was observed by the Advanced LIGO and Virgo detectors, and the gamma-ray burst (GRB) GRB 170817A was observed independently…
