Chandra Shekhar Saraf

About

I am a postdoctoral researcher at the Korea Astronomy and Space Science Institute in Daejeon, South Korea Research interests: - understanding the role of systematics affecting the galaxy surveys and their impact on testing different cosmological models including the standard cosmological model(ΛCDM), dark energy models and Modified Gravity theories, - understanding the effects and observational signatures of different theories of gravity at astrophysical scales, - optimal reconstruction of CMB lensing potential from future CMB polarisation and temperature data, - clustering of galaxies and the effects of Redshift Space Distortions, inhomogeneous models of cosmology and their observational significance. In addition to the above, I am Junior Assistant in the Dark Energy Science Collaboration (DESC) of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), member in CMB Bharat, Wide Field Spectroscopic Telescope and the Evolutionary Map of the Universe (EMU) survey.
