Modeling Gravitational Wave Bias from 3D Power Spectra of Spectroscopic Surveys
Dorsa Sadat Hosseini, Amir Dehghani, J. Leo Kim +3
We present a framework for relating gravitational wave (GW) sources to the astrophysical properties of spectroscopic galaxy samples. We show how this can enable using clustering me…
BBH-Genesis: Disentangling Binary Black Hole Formation Channels with GWTC-4
Shaunak Padhyegurjar, Suvodip Mukherjee
The detected population of binary black holes (BBHs) from the gravitational wave (GW) data has made it possible to decipher their formation and evolution history over cosmic time.…
How lonely are the Binary Compact Objects Detected by the LIGO-Virgo-KAGRA Collaboration?
Devesh Giri, Suvodip Mukherjee
Gravitational-wave (GW) observations of compact binary coalescences (CBCs) are traditionally interpreted under the assumption that the binary evolves in isolation. However, in real…
False Alarm Rates in Detecting Gravitational Wave Lensing from Astrophysical Coincidences: Insights with Model-Independent Technique GLANCE
Aniruddha Chakraborty, Suvodip Mukherjee
Lensing of gravitational waves (GWs) due to intervening massive astrophysical systems between the source and the observer is an inevitable consequence of the general theory of rela…
Hint towards inconsistency between BAO and Supernovae Dataset: The Evidence of Redshift Evolving Dark Energy from DESI DR2 is Absent
Samsuzzaman Afroz, Suvodip Mukherjee
The combination of independent cosmological datasets is a route towards precise and accurate inference of cosmological parameters if these observations are free from systematic eff…
Detecting Axion-like particles using Cosmic Variance Cancellation with CMB and Radio surveys
Harsh Mehta, Anaya Dixit, Suvodip Mukherjee +1
Axions and axion-like particles (ALPs) arise naturally in many extensions of the Standard Model and are among the well-motivated candidates for dark matter. In the presence of magn…
