Blinded Mock Data Challenge for Gravitational-Wave Cosmology-I: Assessing the Robustness of Methods Using Binary Black Holes Mass Spectrum
Aman Agarwal, Ulyana Dupletsa, Konstantin Leyde +18
Gravitational Wave (GW) sources are standard sirens that provide an independent way to map the cosmic expansion history by combining with an independent redshift measurement either…
Phase Space of Binary Black Holes from Gravitational Wave Observations to Unveil its Formation History
Samsuzzaman Afroz, Suvodip Mukherjee
Gravitational Wave (GW) sources offer a valuable window to the physical processes that govern the formation of binary compact objects (BCOs). However, deciphering such information…
Accelerated parameter estimation of supermassive black hole binaries in LISA using a meshfree approximation
Abhishek Sharma, Anand S. Sengupta, Suvodip Mukherjee
The Laser Interferometer Space Antenna (LISA) will be capable of detecting gravitational waves (GWs) in the milli-Hertz band. Among various sources, LISA will detect the coalescenc…
SpectrAx: Spectral Search of Axion-Like Particles Using Multi-Band Observations of Galaxy Clusters from SKA, SO, CMB-S4 and eROSITA
Harsh Mehta, Suvodip Mukherjee
The existence of axions or Axion-Like Particles (ALPs) has been predicted by various Beyond Standard Model (BSM) theories, and the proposed photon-ALP interaction is one of the way…
Discovering the Cosmic Evolution of Supermassive Black Holes using Nano-Hertz Gravitational Waves and Galaxy Surveys
Mohit Raj Sah, Suvodip Mukherjee
The formation and evolution of supermassive black holes (SMBHs) in the Universe remains an open question in cosmology. We show for the first time that the evolution of SMBHs with r…
Prospect of Precision Cosmology and Testing General Relativity using Binary Black Holes- Galaxies Cross-correlation
Samsuzzaman Afroz, Suvodip Mukherjee
Modified theories of gravity predict deviations from General Relativity (GR) in the propagation of gravitational waves (GW) across cosmological distances. A key prediction is that…
A Model-Independent Precision Test of General Relativity using LISA Bright Standard Sirens
Samsuzzaman Afroz, Suvodip Mukherjee
The upcoming Laser Interferometer Space Antenna (LISA), set for launch in the mid-2030s, will enhance our capability to probe the universe through gravitational waves (GWs) emitted…
A Diffused Background from Axion-like Particles in the Microwave Sky
Harsh Mehta, Suvodip Mukherjee
The nature of dark matter is an unsolved cosmological problem and axions are one of the weakly interacting cold dark matter candidates. Axions or ALPs (Axion-like particles) are ps…
A power spectrum approach to the search for Axion-like Particles from resolved galaxy clusters using CMB as a backlight
Harsh Mehta, Suvodip Mukherjee
Axions or ALPs are hypothetical particles predicted by BSM theories, which make one of the dark matter candidates. These particles can convert into photons and vice-versa in the pr…
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…
