Refractive neutrino masses in the solar DM halo: Can the dark-LMA solution be revived?
Susobhan Chattopadhyay, Amol Dighe
Neutrinos can acquire "refractive masses" as a consequence of their interactions with ultralight dark matter (DM). We explore a model with two additional sterile neutrinos and an u…
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…
Exploring constraints on the core radius and density jumps inside Earth using atmospheric neutrino oscillations
Anuj Kumar Upadhyay, Anil Kumar, Sanjib Kumar Agarwalla +1
Atmospheric neutrinos, through their weak interactions, can serve as an independent tool for exploring the internal structure of Earth. The information obtained would be complement…
Constraining electromagnetic couplings of ultralight scalars from compact stars
Tanmay Kumar Poddar, Amol Dighe
If an ultralight scalar interacts with the electromagnetic fields of a compact rotating star, then a long-range scalar field is developed outside the star. The Coulomb-like profile…
