HESS J1507-622: A Plausible Young Galactic Kilonova Remnant
Prantik Sarmah, Xilu Wang, Myles Carley +3
HESS J1507622 is an unusual TeV gamma-ray source in the H.E.S.S. Galactic Plane Survey, distinguished by its off-plane location () and compact angular ext…
Neutrino mass ordering from the next Galactic supernova at DUNE, HK, and JUNO
Prantik Sarmah, Sovan Chakraborty, Abinash Medhi +2
The next Galactic core-collapse supernova (CCSN) will offer a unique opportunity to determine the neutrino mass ordering. We focus on two observables: the electron neutrino ()…
High-energy Neutrino Predictions for T Coronae Borealis: Probing Particle Acceleration in Novae
Prantik Sarmah, Sovan Chakraborty, Xilu Wang
The MAGIC detection of near-TeV gamma rays from the 2021 RS Oph ( kpc) outburst has established recurrent novae as TeV particle accelerators. However, the origin of this emis…
Constraining Gravitational Dark Matter with LHAASO and Fermi-LAT
Basabendu Barman, Arindam Das, Prantik Sarmah +1
We use diffuse Galactic high energy gamma ray data from LHAASO and Fermi-LAT to constrain gravitationally produced decaying dark matter (DM). Focusing on four benchmark candidates:…
A White Paper on The Multi-Messenger Science Landscape in India
Samsuzzaman Afroz, Sanjib Kumar Agarwalla, Dipankar Bhattacharya +35
The multi-messenger science using different observational windows to the Universe such as Gravitational Waves (GWs), Electromagnetic Waves (EMs), Cosmic Rays (CRs), and Neutrinos o…
What KM3-230213A events may tell us about the neutrino mass and dark matter
Basabendu Barman, Arindam Das, Prantik Sarmah
Within the framework of general scenario, we demonstrate that the ultra high energy neutrinos recently detected by KM3NeT could originate from a decaying right handed neutri…
Possible origin of the KM3-230213A neutrino event from dark matter decay
Debasish Borah, Nayan Das, Nobuchika Okada +1
We study the possibility of the highest energy neutrino event with 220 PeV energy, detected recently by the KM3NeT experiment to be originating from heavy dark matter (DM) decay. C…
The Amaterasu particle: constraining the superheavy dark matter origin of UHECRs
Prantik Sarmah, Nayan Das, Debasish Borah +2
Amaterasu, the second most energetic ( EeV) cosmic ray particle has been recently detected by the Telescope Array (TA) surface detector. The origin of the TA Amaterasu event i…
Gamma-rays and Neutrinos from Giant Molecular Cloud Populations in the Galactic Plane
Abhijit Roy, Jagdish C. Joshi, Martina Cardillo +3
The recent IceCube detection of significant neutrino flux from the inner Galactic plane has provided us valuable insights on the spectrum of cosmic rays in our Galaxy. This flux ca…
A relook at the GZK Neutrino-Photon Connection: Impact of Extra-galactic Radio Background & UHECR properties
Sovan Chakraborty, Poonam Mehta, Prantik Sarmah
Ultra-high energy cosmic rays (UHECRs) beyond the Greisen-Zatsepin-Kuzmin (GZK) cut-off provide us with a unique opportunity to understand the universe at extreme energies. Seconda…
New constraints on the gamma-ray and high energy neutrino fluxes from the circumstellar interaction of SN 2023ixf
Prantik Sarmah
The recent supernova, SN 2023ixf, one of the closest observed type II SNe has revealed the presence of a dense circumstellar material (CSM). Interaction of the SN ejecta with this…
Gamma-rays and neutrinos from supernovae of Type Ib/c with late time emission
Prantik Sarmah, Sovan Chakraborty, Irene Tamborra +1
Observations of some supernovae (SNe), such as SN 2014C, in the X-ray and radio wavebands revealed a rebrightening over a timescale of about a year since their detection. Such a di…
Probing LHAASO Galactic PeVatrons through gamma-ray and neutrino correspondence
Prantik Sarmah, Sovan Chakraborty, Jagdish C. Joshi
Recently, Large High Altitude Air Shower Observatory (LHAASO) has detected several Galactic point sources of ultra high energy (UHE; TeV) gamma-rays. These gamma-rays ar…
High energy particles from young supernovae: gamma-ray and neutrino connections
Prantik Sarmah, Sovan Chakraborty, Irene Tamborra +1
Young core-collapse supernovae (YSNe) are factories of high-energy neutrinos and gamma-rays as the shock accelerated protons efficiently interact with the protons in the dense circ…
The Hyper-Kamiokande Experiment -- Snowmass LOI
