Positron Excess from Cosmic Ray Interactions in Galactic Molecular Clouds
Agnibha De Sarkar, Sayan Biswas, Nayantara Gupta
The recently observed data by AMS-02 clearly confirms that the positron flux rises with energy and shows a peak near a few hundred GeV. This rising positron flux cannot be explaine…
Multiwavelength analysis of low surface brightness galaxies to study possible dark matter signature
Pooja Bhattacharjee, Pratik Majumdar, Mousumi Das +3
Low Surface Brightness (LSB) galaxies have very diffuse, low surface density stellar disks which appear faint in optical images. They are very rich in neutral hydrogen (HI) gas, wh…
Galactic Gamma Ray Background from Interactions of Cosmic Rays
Sayan Biswas, Nayantara Gupta
Various studies firmly establish the fact that gamma-ray observations can act as a unique probe to detect the possible cosmic ray (CR) sources, study the CR density distribution an…
