A very-high-energy component deep in the Gamma-ray Burst afterglow
H. Abdalla R. Adam F. Aharonian F. Ait Benkhali E. O. Anguener M. Arakawa, C. Arcaro, C. Armand +219
Gamma-ray bursts (GRBs) are brief flashes of gamma rays, considered to be the most energetic explosive phenomena in the Universe. The emission from GRBs comprises a short (typicall…
The thermal-radiative wind in low mass X-ray binary H 1743-322: II. iron line predictions from Monte Carlo radiation transfer
Ryota Tomaru, Chris Done, Ken Ohsuga +2
We show the best current simulations of the absorption and emission features predicted from thermal-radiative winds produced from X-ray illumination of the outer accretion disc in…
Estimation of the detected background by the future gamma-ray transient mission CAMELOT
J. Ripa, G. Galgóczi, N. Werner +18
This study presents a background estimation for the Cubesats Applied for MEasuring and LOcalising Transients (CAMELOT), which is a proposed fleet of nanosatellites for the all-sky…
Temporal and spectral X-ray properties of magnetar SGR 1900+14 derived from observations with NuSTAR and XMM-Newton
Tsubasa Tamba, Aya Bamba, Hirokazu Odaka +1
X-ray observations play a crucial role in understanding the emission mechanism and relevant physical phenomena of magnetars. We report X-ray observations of a young magnetar SGR 19…
Constraints on the emission region of 3C 279 during strong flares in 2014 and 2015 through VHE gamma-ray observations with H.E.S.S
H. E. S. S. Collaboration, H. Abdalla, R. Adam +224
The flat spectrum radio quasar 3C 279 is known to exhibit pronounced variability in the high-energy (MeVGeV) -ray band, which is continuously monitored with Fer…
H.E.S.S. and Suzaku observations of the Vela X pulsar wind nebula
H. E. S. S. Collaboration
Pulsar Wind Nebulae (PWNe) represent the most prominent population of Galactic very-high-energy gamma-ray sources and are thought to be an efficient source of leptonic cosmic rays.…
Upper Limits on Very-High-Energy Gamma-ray Emission from Core-Collapse Supernovae Observed with H.E.S.S
H. E. S. S. Collaboration, :, H. Abdalla +225
Young core-collapse supernovae with dense-wind progenitors may be able to accelerate cosmic-ray hadrons beyond the knee of the cosmic-ray spectrum, and this may result in measurabl…
X-Ray Spectral Model from Clumpy Torus and Its Application to Circinus Galaxy
Atsushi Tanimoto, Yoshihiro Ueda, Hirokazu Odaka +3
We construct an X-ray spectral model from the clumpy torus in an active galactic nucleus (AGN), designated as "XCLUMPY", utilizing the Monte Carlo simulation for Astrophysics and C…
The 2014 TeV Gamma-ray Flare of Mrk 501 Seen with H.E.S.S.: Temporal and Spectral Constraints on Lorentz Invariance Violation
H. E. S. S. Collaboration, :, H. Abdalla +232
The blazar Mrk 501 (z=0.034) was observed at very-high-energy (VHE, ~GeV) gamma-ray wavelengths during a bright flare on the night of 2014 June 23-24 (MJD 56832) with…
Dual MeV Gamma-Ray and Dark Matter Observatory -- GRAMS Project
Tsuguo Aramaki, Per Hansson Adrian, Georgia Karagiorgi +1
GRAMS (Gamma-Ray and AntiMatter Survey) is a novel project that can simultaneously target both astrophysical observations with MeV gamma rays and an indirect dark matter search wit…
