Alumni
Gautam Saikia
Research ScholarYear of joining: 2015
Research interests: Cosmic Dust; Infrared Astronomy
Work summary: Gautam worked on exploring the origins of Cosmic Dust in the Milky Way and nearby galaxies and in the process, unraveling hitherto unknown facts and properties of different kinds of dust present all around us. He used observational data from multi-wavelength observatories to carry out analysis with the help of computational techniques and study dust properties such as extinction, polarization, and so on.
He is currently trying to understand various dust-gas interactions and how they contribute towards the emission features observed within different interstellar environments using data from multi-wavelength observatories and surveys.
Current Position: Assistant Professor, North Guwahati College, Guwahati, Assam.

Pranjupriya Goswami
Research ScholarYear of joining: 2016
Research interests: Spectral curvature and variability study in astrophysical Blazars
Work summary: Pranjupriya worked on the study of X-ray spectral curvatures in Blazars with NuSTAR observations and modelling of the spectral curvature as a result of diffusive processes. This is a probe to understand the particle distribution and the radiative mechanism within the jet.
Current Position: Post Doctoral Fellow, Centre for Space Research, North West University, South Africa.

Anshuman Borgohain
Research Scholar; DST INSPIRE JRFYear of joining: 2017
Research interests: Astrophysics of galaxies; Galaxy evolution; Dwarf galaxies
Work summary: Anshuman is currently involved in multi-wavelength studies of galaxies which holds a wealth of information in their assembly history. Such studies help to understand the global properties of galaxies and in turn will help to infer how galaxies grow and evolve over cosmic time.
