About LGCA


Laboratory of Gravitation, Cosmology and Astrophysics was founded by Prof Sergey Chervon in 2012 on base of Ulyanovsk State Pedagogical University. LGCA has strong connection to Russian Gravitation Society (RGS) participating in conferences organized by RGS and acting as a host for RGS conferences such as RUSGRAV 2011, UISS 2016 etc.
