Finding strangelets in cosmic rays from HESS J1731-347, a possible strange quark star using the Cherenkov Telescope Array Observatory
C. R. Das
The hypothesis that supernova remnants are key sources of Galactic cosmic rays gains support from evidence that HESS J1731-347 one of the few Galactic objects capable of accelerati…
Strangelet Searches from Neutron Stars, Binary Mergers, and Gamma-Ray Bursts with Current and Future Observatories
C. R. Das
Strange quark matter (SQM) is considered a possible true ground state of QCD at high densities. This idea motivates research on exotic compact objects and certain cosmic-ray phenom…
Ultralight axion or axion-like particle dark matter and 21-cm absorption signals in new physics
C. R. Das
A hypothetical particle known as the axion holds the potential to resolve both the cosmic dark matter riddle and particle physics' long-standing, strong CP dilemma. An unusually st…
The axion signature of strange quark star in SGR 0501+4516
C. R. Das
We study the axion effects on quark matter and quark-matter cores in strange quark magnetars using a three-flavor Nambu-Jona-Lasinio model to represent the charge-parity violating…
