Conventional vs. modified GTD metrics: Survival of modified GTD metrics in AdS spacetime and thermodynamic ensembles
Gunindra Krishna Mahanta
Thermodynamic geometry provides a powerful framework for probing the microscopic structure of thermodynamic systems. Among its formulations, Geometrothermodynamics (GTD) has been w…
Particle acceleration to PeV energies in Pulsar Wind Nebula: a two zone model
Gunindra Krishna Mahanta, Nilay Bhatt, Bitan Ghosal +1
\textit{PeVatrons} are the extreme galactic accelerators capable of producing PeV particles. Recent observation of Large High Altitude Air Shower Observatory have detected UHE phot…
Thermodynamic Geodesics in Bardeen Regular Black Hole: Conventional vs. Modified Geometrothermodynamics Metrics
Gunindra Krishna Mahanta
Thermodynamic geometry allow us to study the microscopic behavior of black hole system by defining a metric structure in thermodynamic phase space. Among the various thermodynamic…
uGMRT observation of the unidentified PeVatron candidate LHAASO J2108+5157
Gunindra Krishna Mahanta, Subhashis Roy, Sagar Godambe +3
Recent observations by the Large High Altitude Air Shower Observatory (LHAASO) detected Ultra High Energy (UHE) photons in the range 100 TeV to 1.4 PeV from twelve sources includin…
