An Accurate Modeling of Nano-hertz Gravitational Wave Signal from Eccentric Supermassive Binary Black Holes: An Essential Step Toward a Robust Discovery
Mohit Raj Sah, Akash Maurya, Suvodip Mukherjee +7
The stochastic gravitational wave background (SGWB) in the nanohertz (nHz) regime, detectable by pulsar timing arrays (PTAs), provides a promising probe of the cosmic population of…

Imprints of Supermassive Black Hole Evolution on the Spectral and Spatial Anisotropy of Nano-Hertz Stochastic Gravitational-Wave Background
Mohit Raj Sah, Suvodip Mukherjee, Vida Saeedzadeh +3
The formation and evolution of supermassive black holes (SMBHs) remains an open question in the field of modern cosmology. The detection of nanohertz (n-Hz) gravitational waves via…

Dual AGNs: Precursors of Binary Supermassive Black Hole Formation and Mergers
Vida Saeedzadeh, Arif Babul, Suvodip Mukherjee +3
The presence of dual active galactic nuclei (AGN) on scales of a few tens of kpc can be used to study merger-induced accretion on supermassive black holes (SMBHs) and offer insight…
