Constraining the nature of the most extreme Galactic particle accelerator. H.E.S.S. observations of the microquasar V4641 Sgr
A. Acharyya, F. Aharonian, H. Ashkar +131
Microquasars have emerged as promising candidates to explain the cosmic-ray flux at petaelectronvolt energies. LHAASO observations revealed V4641~Sgr as the most extreme example so…
Probing a cosmogenic origin of astrophysical neutrinos and cosmic rays using gamma-ray observations of TXS 0506+056
A. Acharyya, A. Archer, P. Bangale +58
In September 2017, a high-energy neutrino event detected by the IceCube Neutrino Observatory (IceCube-170922A) was associated, at the level, with a gamma-ray flare from the bl…
Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
K. Abe, S. Abe, J. Abhir +491
The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…
A Systematic Search for MeV-GeV Pulsar Wind Nebulae without Gamma-ray Detected Pulsars
Jordan Eagle, Daniel Castro, Wei Zhang +3
An increasing number of pulsar wind nebulae (PWNe) are being identified in the TeV band by ground-based Imaging Air Cherenkov Telescopes such that they constitute the dominant sour…
Puzzling Variation of Gamma Rays from the Sun over the Solar Cycle Revealed with Fermi-LAT
A. Acharyya, A. Adelfio, M. Ajello +100
The steady-state gamma-ray emission from the Sun is thought to consist of two emission components due to interactions with Galactic cosmic rays: (1) a hadronic disk component, and…
Characterizing Candidate Blazar Counterparts of the Ultra-High-Energy Event KM3-230213A
KM3NeT Collaboration, MessMapp Group, LAT Collaboration +13
High-energy astrophysical neutrinos serve as crucial messengers for understanding hadronic acceleration processes and identifying the origins of cosmic rays, with blazars among the…
An in-depth study of Gamma rays from the Starburst Galaxy M 82 with VERITAS
Atreya Acharyya, Colin B. Adams, Priyadarshini Bangale +60
Assuming Galactic cosmic rays originate in supernovae and the winds of massive stars, starburst galaxies should produce very-high-energy (VHE; E100 GeV) gamma-ray emission via t…
Search for Extended GeV Sources in the Inner Galactic Plane
S. Abdollahi, F. Acero, A. Acharyya +108
The recent detection of extended -ray emission around middle-aged pulsars is interpreted as inverse-Compton scattering of ambient photons by electron-positron pairs escaping the…
A multi-wavelength study to decipher the 2017 flare of the blazar OJ 287
A. Acharyya, C. B. Adams, A. Archer +71
In February 2017, the blazar OJ~287 underwent a period of intense multiwavelength activity. It reached a new historic peak in the soft X-ray (0.3-10 keV) band, as measured by Swift…
Multiwavelength Investigation of -ray Source MGRO J1908+06 Emission Using Fermi-LAT, VERITAS, and HAWC
The VERITAS collaboration, The HAWC collaboration, LAT collaboration
This paper investigates the origin of the -ray emission from MGRO J1908+06 in the GeV-TeV energy band. By analyzing the data collected by {\it Fermi}-LAT, VERITAS, and HAWC, wit…
An indirect search for dark matter with a combined analysis of dwarf spheroidal galaxies from VERITAS
A. Acharyya, C. B. Adams, P. Bangale +59
Understanding the nature and identity of dark matter is a key goal in the physics community. In the case that TeV-scale dark matter particles decay or annihilate into standard mode…
Galactic transient sources with the Cherenkov Telescope Array Observatory
