Understanding SSM-IMRIs (Intermediate Mass-Ratio Inspirals with a sub-solar mass black hole like compact object) through gravitational waves with LIGO-Virgo and ET.

Project in GWDA supervised by Dr. Karan JaniThe current gravitational wave signals from CBCs observed by LIGO-Virgo are not very well localized. The upcoming LIGO-India (Aundh) and LIGO-Livingston pair provide the longest baseline amongst all pairs of current and in-construction GW detectors, and the inclusion of LIGO-India in the detector network can significantly improve the localization of sources by using detector triangulation. The network expansion can improve the sky-localization… Show more Project in GWDA supervised by Dr. Karan JaniThe current gravitational wave signals from CBCs observed by LIGO-Virgo are not very well localized. The upcoming LIGO-India (Aundh) and LIGO-Livingston pair provide the longest baseline amongst all pairs of current and in-construction GW detectors, and the inclusion of LIGO-India in the detector network can significantly improve the localization of sources by using detector triangulation. The network expansion can improve the sky-localization area from ~100 sq. deg. to ~1 sq. deg. and break the degeneracy between distance-inclination.To demonstrate this, we systematically injected GW190521-like systems (at Advanced LIGO and Advanced Virgo design sensitivity) into the HLV and HLVI detector network and recovered the parameters (Bayesian PE) using phenomenological and surrogate GW waveforms (IMRPhenomXPHM and NRSur7dq4).

I got an exposure to a spectrum of things at NCRA-TIFR where Dr. Yashwant Gupta, Dr. Ruta Kale and Dr. Yogesh Wadadekar served as guides for the program. I also explored a number of things on my own during the period. A summary of everything done in the period:• An overview of multi-wavelength astronomy, mechanism of radio telescopes and GMRT.• Qualitative descriptions of neutron stars, pulsars, AGNs.• Learned to work with FITS files and about mean and median stacking with some… Show more I got an exposure to a spectrum of things at NCRA-TIFR where Dr. Yashwant Gupta, Dr. Ruta Kale and Dr. Yogesh Wadadekar served as guides for the program.

Worked with AT20G BSS catalogue and SuperCOSMOS all-sky catalogue to learn about cross-matching• Learned about optimisation and used NumPy optimisation, Sorting optimisation and Binary search optimisation.• Learned about k-d trees optimisation using Astropy Show less
