The Syracuse University Physics Department is pleased to welcome Dr. Sumit Kumar, Postdoctoral Researcher from the Max Planck Institute for Gravitational Physics. Sumit works with Astroparticle Physics and Cosmology and will give a talk as part of the Gravitational Wave Seminar Series.


The third-generation (3G) Gravitational wave (GW) detectors such as the Cosmic Explorer or Einstein telescope are expected to detect thousands of GW merger events per year with localization area less than a degree square. This will enable us to probe the large-scale structure (LSS) features – such as baryon acoustic oscillations (BAO), and clustering bias — solely from the GW observations. In this talk, I will discuss the methods to detect LSS features in the 3G detectors era and their implications for precision cosmology. Additionally, I will focus on the optimal strategies for synergizing data from BAO observations in galaxy surveys with that of GW events, and discuss how it can refine parameter constraints for diverse cosmological models, beyond the standard cosmological framework. Analyzing the redshift-dependent evolution of LSS features could provide insights into the connection between compact binary formation and broader structure formation during the evolution of the Universe.
