Joint searches by FACT, H.E.S.S., MAGIC and VERITAS for VHE gamma-ray emission associated with neutrinos detected by IceCube
Fabian Schüssler, Halim Ashkar, Elisa Bernardini +11
The sources of the astrophysical flux of high-energy neutrinos detected by IceCube are still largely unknown, but searches for temporal and spatial correlation between neutrinos an…
Richardson-Lucy deconvolution with a spatially Variant point-spread function of Chandra: Supernova Remnant Cassiopeia A as an Example
Yusuke Sakai, Shinya Yamada, Toshiki Sato +3
Richardson-Lucy (RL) deconvolution is one of the classical methods widely used in X-ray astronomy and other areas. Amid recent progress in image processing, RL deconvolution still…
Constraints on the intergalactic magnetic field using Fermi-LAT and H.E.S.S. blazar observations
H. E. S. S., Fermi-LAT Collaborations, : +134
Magnetic fields in galaxies and galaxy clusters are believed to be the result of the amplification of intergalactic seed fields during the formation of large-scale structures in th…
MASTER OT J030227.28+191754.5: a dwarf nova at a massive oxygen-neon white-dwarf system ?
Mariko Kimura, Kazumi Kashiyama, Toshikazu Shigeyama +3
We present timing and spectral analysis results of the {\it NICER} and {\it NuSTAR} observations of the dwarf nova MASTER OT J030227.28191754.5 during the 2021--2022 outburst. T…
Gamma-Ray Emission in the Seyfert Galaxy NGC 4151: Investigating the Role of Jet and Coronal Activities
Yoshiyuki Inoue, Dmitry Khangulyan
NGC 4151, a nearby Seyfert galaxy, has recently been reported to emit gamma rays in the GeV range, posing an intriguing astrophysical mystery. The star formation rate of NGC 4151 i…
Search for the evaporation of primordial black holes with H.E.S.S
H. E. S. S. collaboration, :, F. Aharonian +146
Primordial Black Holes (PBHs) are hypothetical black holes predicted to have been formed from density fluctuations in the early Universe. PBHs with an initial mass around $10^{14}-…
Unveiling properties of the non-thermal X-ray production in the gamma-ray binary LS 5039 using the long-term pattern of its fast X-ray variability
Hiroki Yoneda, Valenti Bosch-Ramon, Teruaki Enoto +5
Gamma-ray binary systems, a subclass of high-mass X-ray binaries, show non-thermal emissions from radio to TeV. While efficient electron acceleration is considered to take place in…
H.E.S.S. follow-up observations of GRB221009A
H. E. S. S. Collaboration, :, F. Aharonian +159
GRB221009A is the brightest gamma-ray burst ever detected. To probe the very-high-energy (VHE, \!100 GeV) emission, the High Energy Stereoscopic System (H.E.S.S.) began observat…
The peak-flux of GRB 221009A measured with GRBAlpha
Jakub Ripa, Hiromitsu Takahashi, Yasushi Fukazawa +42
The brightest gamma-ray burst ever observed, long-duration GRB 221009A, was detected by GRBAlpha nano-satellite without saturation. We present light curves of the prompt emission i…
HESS J1809193: a halo of escaped electrons around a pulsar wind nebula?
H. E. S. S. Collaboration, :, F. Aharonian +151
Context. HESS J1809193 is an unassociated very-high-energy -ray source located on the Galactic plane. While it has been connected to the nebula of the energetic pulsar PSR J1…
The formation of hard VHE spectra from GRB afterglow via Two-Zone Synchrotron Self-Compton Emission
Dmitry Khangulyan, Andrew M. Taylor, Felix Aharonian
Electron Compton scattering of target photons into the gamma-ray energy band (inverse Compton scattering --IC--) is commonly expected to dominate the very high energy spectra in ga…
Spatio-temporal characterization of Cassiopeia A
Yuto Ichinohe, Toshiki Sato
Analyzing the X-ray data of supernova remnants (SNRs) are among the most challenging task in the current X-ray astronomy because SNRs are both spatially extended and variable over…
MeV Gamma-Ray Source Contribution to the Inner Galactic Diffuse Emission
Naomi Tsuji, Yoshiyuki Inoue, Hiroki Yoneda +2
The origin of the inner Galactic emission, measured by COMPTEL with a flux of in the 1-30 MeV energy range from the…
