Synthetic Polarization of the CMZ
This project aims to model the synthetic polarization of the Central Molecular Zone (CMZ), using magneto-hydrodynamical simulations and the Polarized Radiation Simulator (POLARIS).
Hello! I am an astrophysicist specializing in the study of dust and magnetic field of our Galaxy. My PhD work focussed on the 3D radiative transfer model of the Diffuse Galactic Light (DGL) in the Milky Way. We mapped the expected dust scattered radiation at high Galactic latitudes in the ultraviolet waveband and found an excess that could not be accounted for with the conventional sources. As a postdoc at KASI, I have explored the interaction between the interstellar dust grains and the magnetic field at the centre of our Galaxy and how they can be investigated using thermal infrared polarization observations. I have experience working with photometric, spectroscopic, and polarimetric observations from GALEX, SOFIA, JCMT, Herschel, Planck, Pan-STARRS1, and IRAS. My current research is focused on the synthetic polarization of the Central Molecular Zone (CMZ) using the 3D Monte-Carlo radiative transfer code POLArized RadIation Simulator (POLARIS) and magnetohydrodynamical simulations, to understand the grain alignment properties and potentially map the 3D strength and morphology of the magnetic field of the CMZ.
