  Highlights  

In the late 1970s, Vera Rubin showed that flat rotation curves are ubiquitous in local spiral galaxies and concluded that “galaxies are surrounded by a dark matter halo that extends much farther than their visible matter”. These observational results were later supported by theoretical models of structure formation. Since then, dark matter has become an essential building block of cosmological models. However, its nature remains a mystery that can be solved either by detecting dark matter particles or by constraining the structural properties of the dark matter halo (e.g. the relationship between its density and radius). I am working on the latter, and have recently shown that the structural properties of dark matter halos have evolved over cosmic time. Some of the interesting results are Highlighted below, and full list of publication can be found here!

      About Me  

    In 2012, I graduated with a bachelor's degree in mathematics from Jiwaji University in India, and then journey of becoming an astrophysicist begun. In 2013, I was selected for a research assistant (telescope trainee) position at the Indian Institute of Astrophysics (IIA) in Bangalore, India. I worked there for about two years. In 2015, I was selected for the Master SPaCE programme and received a fellowship funded by the Amedix Foundation for two years. I did my Master's in Astrophysics at the Laboratoire d'Astrophysique de Marseille, Aix-Marseille University, France. In 2017, I won a PhD position in Astrophysics and Cosmology at SISSA in Italy, fully funded by the Italian Ministry of Higher Education.

    My main research interest lies in studying the dark matter in galaxies. Currently, I am on to constrain the evolution of dark matter halos with cosmic time. Therefore, my work so far has been concentrated on the proof-of-principle of decomposing the rotation curves of high redshift galaxies into their constituents of stars, gas, and dark matter. In addition to this, I have analysed state-of-the-art cosmological galaxy simulations and compared them with observations. After finishing my PhD, in Oct 2021, I won the prestigious SARAO fellowship to work on world's leading radio facilities (MeerKAT and SKA). Since 2022, I am an independent post-doc researcher at the University of Western Cape, hosted by Prof. Lerothodi Leeuw. I will primarily be working on MeerKAT high-z surveys, for example MIGHTEE and LADUMA. If you want to know more about my work, or wish to collaborate, please contact via email.
