Cosmogenic Origin of KM3-230213A: Delayed Gamma-Ray Emission from A Cosmic-Ray Transient
Sovan Boxi, Saikat Das, Nayantara Gupta
The highest-energy cosmic neutrino detected by the ARCA detector of KM3NeT has reignited the quest to pinpoint the sources of ultrahigh-energy cosmic rays (UHECRs; E…
Design and Fabrication of a lightweight three-lens corrector system for the 2.34-m Vainu Bappu Telescope
Nitish Singh, S. Sriram, Ramya Sethuram +8
The Vainu Bappu Telescope (VBT) is a 2.34-m reflector, primarily supported on-axis field of view, offering high-resolution and low-to-medium resolution spectroscopic observations i…
Cosmic Clues from Amaterasu: Blazar-Driven Ultrahigh-Energy Cosmic Rays?
Saikat Das, Srijita Hazra, Nayantara Gupta
The detection of the Amaterasu event of energy 244 EeV by the Telescope Array, one of the most energetic ultrahigh-energy cosmic rays (UHECRs; EeV) observed to date,…
Cosmic-Ray Constraints on the Flux of Ultra-High-Energy Neutrino Event KM3-230213A
Saikat Das, Bing Zhang, Soebur Razzaque +1
The detection of a ~PeV muon neutrino event by the KM3NeT telescope offers an unprecedented opportunity to probe the Universe at extreme energies. A photopion interactio…
Composite asymmetric dark matter with a dark photon portal: Multimessenger tests
Saikat Das, Ayuki Kamada, Takumi Kuwahara +2
Composite asymmetric dark matter (ADM) is the framework that naturally explains the coincidence of the baryon density and the dark matter density of the Universe. Through a portal…
