IMG_2962My name is Satya Gontcho A Gontcho. As a physicist who works at the interface between astrophysics and cosmology, my core interest is to study the Large Scale Structures of the Universe and use them to better our understanding of Dark Energy.  In particular, I use quasars and the absorption features in their spectra as tracers of the mass density field.

Involved in the Baryon Oscillation Spectroscopic Survey (BOSS) from 2012 to 2017, I am now part of the Dark Energy Spectroscopic Instrument (DESI). These are particularly exciting times since DESI has seen its first light on October 22nd 2019 ! Over the next 5 years, DESI will obtain optical spectra for tens of millions of galaxies and quasars, constructing an unprecedented 3D map spanning the nearby universe to 11 billion light years. These will be used to measure the effect of Dark Energy on the expansion of the Universe. A lot of interesting work in perspective.
