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…
Velocity dispersion of dark matter deficient ultra-diffuse galaxies: A case for modified gravity
Esha Bhatia, Sayan Chakrabarti, Sovan Chakraborty
The line of sight velocity dispersion of the ultra-diffuse galaxies (UDGs) NGC1052-DF2 and NGC1052-DF4 have been reasonably explained only with the baryonic matter, without requiri…
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…
Supernova fast flavor conversions in 1+1D : Influence of mu-tau neutrinos
Francesco Capozzi, Madhurima Chakraborty, Sovan Chakraborty +1
In the dense supernova environment, neutrinos can undergo fast flavor conversions which depend on the large neutrino-neutrino interaction strength. It has been recently shown that…
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…
