VERITAS and HAWC observations of unidentified source LHAASO J2108+5157
Sajan Kumar, Michael Martin, Xiaojie Wang
Understanding the complete nature of Galactic sources that accelerate cosmic rays up to eV energy (Galactic PeVatrons) is still an unsolved problem in high-energy astroph…
A VERITAS/Breakthrough Listen Search for Optical Technosignatures
Atreya Acharyya, Colin Adams, Avery Archer +65
The Breakthrough Listen Initiative is conducting a program using multiple telescopes around the world to search for "technosignatures": artificial transmitters of extraterrestrial…
Soft Anharmonic Coupled Vibrations of Li and SiO4 Enable Li-ion Diffusion in Amorphous Li2Si2O5
Sajan Kumar, Mayanak K. Gupta, Prabhatasree Goel +7
We present the investigations on atomic dynamics and Li+ diffusion in crystalline and amorphous Li2Si2O5 using quasielastic (QENS) and inelastic neutron scattering (INS) studies su…
Solid-like to Liquid-like Behavior of Cu Diffusion in Superionic Cu2X (X=S, Se): An Inelastic Neutron Scattering and Ab-Initio Molecular Dynamics Investigation
Sajan Kumar, M. K. Gupta, Prabhatasree Goel +5
Cu2Se and Cu2S are excellent model systems of superionic conductors with large diffusion coefficients that have been reported to exhibit different solid-liquid-like Cu-ion diffusio…
Combined dark matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
Celine Armand, Eric Charles, Mattia di Mauro +13
Cosmological and astrophysical observations suggest that 85\% of the total matter of the Universe is made of Dark Matter (DM). However, its nature remains one of the most challengi…
Sodium Diffusion and Dynamics in Na2Ti3O7: Neutron Scattering and Ab-initio Simulations
Ranjan Mittal, Sajan Kumar, Mayanak K. Gupta +7
We have performed quasielastic and inelastic neutron scattering (QENS and INS) measurements from 300 K to 1173 K to investigate the Na-diffusion and underlying host dynamics in Na2…
