Observation of a sudden cessation of a very-high-energy gamma-ray flare in PKS 1510-089 with H.E.S.S. and MAGIC in May 2016
H. E. S. S. Collaboration, H. Abdalla, R. Adam +430
The flat spectrum radio quasar (FSRQ) PKS 1510-089 is known for its complex multiwavelength behavior, and is one of only a few FSRQs detected at very high energy (VHE, GeV…
Detection of large-scale X-ray bubbles in the Milky Way halo
P. Predehl, R. A. Sunyaev, W. Becker +25
The halo of the Milky Way provides a laboratory to study the properties of the shocked hot gas that is predicted by models of galaxy formation. There is observational evidence of e…
X-ray reprocessing in accreting pulsar GX 301-2 observed with Insight-HXMT
L. Ji, V. Doroshenko, V. Suleimanov +100
We investigate the absorption and emission features in observations of GX 301-2 detected with Insight-HXMT/LE in 2017-2019. At different orbital phases, we found prominent Fe Kalph…
An extreme particle accelerator in the Galactic plane: HESS J1826130
H. E. S. S. Collaboration, H. Abdalla, R. Adam +236
The unidentified very-high-energy (VHE; E 0.1 TeV) -ray source, HESS J1826130, was discovered with the High Energy Stereoscopic System (HESS) in the Galactic plane. The a…
The eROSITA X-ray telescope on SRG
P. Predehl, R. Andritschke, V. Arefiev +90
eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is the primary instrument on the Spectrum-Roentgen-Gamma (SRG) mission, which was successfully launched on July 1…
An observational argument against accretion in magnetars
Victor Doroshenko, Andrea Santangelo, Valery Suleimanov +1
The phenomenology of anomalous X-ray pulsars is usually interpreted within the paradigm of very highly magnetized neutron stars, also known as magnetars. According to this paradigm…
Observations of GRO J1744-28 in quiescence with XMM-Newton
Victor Doroshenko, Valery Suleimanov, Sergey Tsygankov +3
We report on the deep observations of the "bursting pulsar" GRO J1744-28, which were performed with XMM-Newton and aimed to clarify the origin of its X-ray emission in quiescence.…
Advances in Understanding High-Mass X-ray Binaries with INTEGRAL and Future Directions
Peter Kretschmar, Felix Fürst, Lara Sidoli +48
High mass X-ray binaries are among the brightest X-ray sources in the Milky Way, as well as in nearby Galaxies. Thanks to their highly variable emissions and complex phenomenology,…
Search for dark matter signals towards a selection of recently-detected DES dwarf galaxy satellites of the Milky Way with H.E.S.S
H. E. S. S. Collaboration, :, H. Abdallah +227
Dwarf spheroidal galaxy satellites of the Milky Way are prime targets for indirect detection of dark matter with gamma rays due to their proximity, high dark matter content and abs…
INTEGRAL view on Cataclysmic Variables and Symbiotic Binaries
Alexander Lutovinov, Valery Suleimanov, Gerardo Juan Manuel Luna +5
Accreting white dwarfs (WDs) constitute a significant fraction of the hard X-ray sources detected by the INTEGRAL observatory. Most of them are magnetic Cataclysmic Variables (CVs)…
Insight-HXMT firm detection of the highest energy fundamental cyclotron resonance scattering feature in the spectrum of GRO J1008-57
M. Y. Ge, L. Ji, S. N. Zhang +118
We report on the observation of the accreting pulsar GRO J1008-57 performed by Insight-HXMT at the peak of the source's 2017 outburst. Pulsations are detected with a spin period of…
Probing the magnetic field in the GW170817 outflow using H.E.S.S. observations
H. E. S. S. Collaboration, :, H. Abdalla +230
The detection of the first electromagnetic counterpart to the binary neutron star (BNS) merger remnant GW170817 established the connection between short -ray bursts and BNS merg…
