"Gravitational Wave Detection and Parameter Estimation"Matthew Benacquista (University of Texas) In light of the recent detections of gravitational waves from binary black holes with LIGO/Virgo, I will discuss the physics of the generation, propagation, and detection of gravitational waves with an emphasis on parameter estimation. In particular, I will highlight the uncertainties and selection effects in the observations and the limitations in determining the origin of these sources.

"Multi-wavelength Variability and QPOs in Blazars"Dr. Alok C. Gupta (Aryabhatta Research Institute of Observational Sciences (ARIES) ) Blazar is a subclass of radio loud AGN which show flux variation in the complete EM spectrum on diverse timescales ranging from as short as a few tens of minutes and as long as several years. The blazar emission is predominantly non-thermal. In the present talk, I will discuss some of interesting recent results published by my group based on multi-wavelength ground and space based data. We have detected flux variation in blazars on diverse time scales, cross-correlated multi-wavelength flux and spectral variabilities. We have also detected quasi-periodic oscillations (QPOs) in time series data of blazars in optical and X-ray bands. I will also briefly describe which are dominant AGN standard models which can explain our findings.
