ABOUT ME

I am pursuing my Ph.D. at the Indian Institute of Technology, Kharagpur(IIT KGP), India. My broad area of research is on High Energy Astrophysics. Presently I am working on the very energetic and brightest electromagnetic explosion in the Universe that is the Gamma-ray burst. My other topic of concern is neutrino physics, for which I am jointly working with the Hyper-K IWCD software analysis group and WatChMal Machine learning group. I believe my work would help to explore the laws of physics in severe conditions.

I have almost 3 years of experience in conducting various astronomical experiments, 4 months in Observational work independently & in the team. I conducted different astronomical experiments along with various numerical & computational analyses using languages like Python & Matlab throughout my working tenure as a visiting researcher. My Master's dissertation was on "Differential Photometry on Star Clusters". To get update about my research work you can check my ResearchGate profile..

RESEARCH

  • One of my primary research areas is modeling the Gamma-ray Burst Afterglow phase at a very high energy regime. It was indeed a significant breakthrough in the entire field of high energy gamma-ray astronomy when on 20th July 2018, High Energy Stereoscopic System (HESS) detected a faint afterglow emission from GRB 180720B, the flux of the spectrum ranges from 100 to 440 GeV(Abdalla et al., 2019). Finally, on 14th January 2019, the MAGIC( Major Atmospheric Gamma Imaging Cherenkov) telescope first detected a long-duration GRB event, named GRB 190114C, where the resulting photons in the afterglow phase reached the TeV energy(MAGIC Collaboration, 2019) regime within the first 10s of analysis. This unambiguous discovery of TeV photons is still an elusive fact. I am developing a framework to explain GRB afterglow emission at very high energy(VHE).

  • Another part of my research revolving around high-energy astroparticle physics is the neutrino. It is a very light particle and having a small cross-section its hardly interacts with matter. In Standard Model, it is assumed that this sub-atomic particle has no mass. More recently, in 2015, the Nobel Prize was awarded for discovering neutrino oscillations using data taken by the Super-Kamiokande (Super-K) and the Sudbury Neutrino Observatory collaborations. This discovery has the profound implication that neutrinos have non-zero but tiny masses and also measured different neutrino oscillation parameters. Hyper-Kamiokande (Hyper-K) is a large volume next-generation underground water Cherenkov detector (Proto-Collaboration et al., 2018), the frontier of neutrino measurements, has been proposed to measure some neutrino oscillation parameters with higher precession and sensitivity. I am in collaboration with IWCD software analysis group to measure electron neutrino cross section to improve sensitivity and precession of CP violation.

  • The multi-PMT sensors inside the particle detectors of Super-Kamiokande (Super-K) can measure neutrinos(Fukuda et al., 2003) by providing detailed images of Cherenkov light from particles which produced in the complicated neutrino interactions occurring in the water. These images need to be analyzed to determine the type of neutrino and estimate its energy and direction, parameters that affect neutrino. For the many-particle reconstruction problem and classifying the particles, Deep Learning segments the entire image. Machine learning also determines the properties of all the particles, contributing to the light observed at each pixel. For this specific work, I am also working with another Hyper-KWatChMal international Machine learning group for water Cherenkov detector to classify complex images, accomplish Particle type identification and to separate & reconstruct single and multi-ring events.
