Review Paper On Laser Interferometer Gravitational-Wave Observatory
In this review paper, the author explains how the Laser Interferometric Gravitational-wave Observatory (LIGO) detects gravitational waves and goes over the differences between initial LIGO and advanced LIGO. Beginning by explaining the formation of gravitational waves, the author then gives an overview of the history and locations of LIGO. In the main part of the paper, the different structures of LIGO are examined: interferometer, laser, beam splitter, arms, mirrors, vibration isolation systems, and photodetector. Finally, the author compares the vibration isolation systems and mirrors used in the initial LIGO and advanced LIGO.

It was with the help of Polygence and as well as my mentor's help I have got this amazing experience of researching on such a field. Polygence helped me overcome my financial burden with their aid, and connected me with a really cool mentor, who has done far more things and have experience working directly with what I wanted to pursue in the future. This was one of the best experience of my life, doing things what undergrads does, I got a perspective of how research field works. which is one of the most valuable lesson that I got.
