Gravitational memory and spacetime symmetries
Symmetries of spacetime infinitely far away from gravitational fields may hint at new laws of nature
Influence of settings of multidirectional detector setup on Gamma-Ray Burst coordinates accuracy
My primary objectives included calibration and tests of gamma-ray detector setup BDRG in order to produce reliable and precise data for scientific investigation. Some data gamma-ray detector DRG data of RELEK satellite, operating in orbit since 2014, has also been processed.
Main results:
- Performance of BDRG detectors of Lomonosov satellite has been investigated during 2 years of laboratory tests. Several calibrations have been performed.
- Temperature-related distortions in BDRG data have been investigated.
- Errors in BDRG coordinate-determining technique have been calculated, by experimentally simulating GRBs at different positions.
- I took part in the development of several projects in Seoul and Paris. Under the supervision of Dr. Bruce Grossan, I wrote the program for real-time GRB detection and processed BAT and UVOT detector data of Swift Satellite in order to predict GRB detection rates for X-Ray, IR/Optical instruments of smaller size.
- I participated in Lomonosov conference for students, PhDs, and young scientists, organized by Moscow University and Ministry of Science and Education.
