Center for Astrophysics Research and Technologies Seminar Series
Searching for Supermassive Binary Black Holes and their Gravitational Waves
Presented by Karishma Bansal (UNM)
The recent discovery of gravitational waves (GWs) by the LIGO collaboration has opened a new observing window on the universe, but it is limited to the GWs in the frequency range of 10 âˆ' 1000 Hz. The main motivation of this thesis is to consider the possibility of detecting low frequency (nHz) GWs. In the pursuit of these waves, we need to find their source of origin and build a detector with required sensitivity. Low-frequency waves are expected as a result of coalescing binary supermassive black holes (SMBBHs). We hope to detect these waves in the near future using pulsar timing arrays (PTAs). Thus, this thesis can be divided into two parts: searching for SMBBHs and improving the sensitivity of PTAs.
