Evidence for a spectral steepening of the gamma-ray emission from the Galactic Center ridge
A. Acharyya, F. Aharonian, H. Ashkar +130
Very-high-energy (VHE) -ray emission detected from the central molecular zone (CMZ) hints at diffusive propagation of cosmic rays (CRs) injected continuously near the Galactic c…
CtaAgnVar : a Pipeline for Variability Studies with the Cherenkov Telescope Array Observatory
G. Grolleron, J. -P. Lenain, J. Biteau +2
Blazars are active galactic nuclei whose relativistic jet points toward the observer, accelerating particles that radiate across the electromagnetic spectrum. Characterizing their…
Gamma-Ray Constraints on Heavy Axion-Like-Particle Decays from Fermi-LAT and H.E.S.S. Blazar Spectra
A. Acharyya, F. Aharonian, M. Backes +117
The propagation of very-high-energy (VHE; GeV) gamma rays from extragalactic sources is affected by interactions with photons of the extragalactic background light (…
Synergy between the Cherenkov Telescope Array Observatory and the Vera C. Rubin Observatory
J. Biteau, J. Hamo, A. Mikhno +2
The Cherenkov Telescope Array Observatory (CTAO) and the Vera C. Rubin Observatory are set to transform our understanding of the universe over the next decade. These two observator…
Search for long-term variability of HESS J1745-290
H. E. S. S. Collaboration, :, A. Acharyya +116
At the center of our Galaxy lies the bright γ-ray point-like source HESS J1745-290, which is compatible in position with Sgr A star, although an association between the two remains…
Chasing Gamma-Ray Signals from Binary Neutron Star Coalescences with the Cherenkov Telescope Array: Prospects and Observing Strategies
S. Abe, J. Abhir, A. Abhishek +457
The detection of gravitational waves (GWs) from a binary neutron star (BNS) merger by Advanced LIGO and Advanced Virgo (GW170817), together with its electromagnetic counterpart, th…
