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…
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…
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…
Modified Cosmology or Modified Galaxy Astrophysics is Driving the z>6 JWST Results? CMB Experiments can discover the Origin in the Near Future
Harsh Mehta, Suvodip Mukherjee
The massive and bright galaxies observed by the James Webb Space Telescope (JWST) at high redshifts () have challenged our understanding of the Universe. This may require re…
Gravitational Wave Burst from Bremsstrahlung in Milky Way Can Discover Sub-Solar Dark Matter in Near Future
Samsuzzaman Afroz, Suvodip Mukherjee
What is Dark Matter, and what is its concentration in the Milky Way remains an open question in physics. We show that if a significant fraction of dark matter is composed of sub-so…
Illuminating Dark Energy with Bright Standard Sirens from Future Detectors
Samsuzzaman Afroz, Suvodip Mukherjee, Gianmassimo Tasinato
Understanding the nature and evolution of dark energy (DE) is a central challenge in modern cosmology. In this work, we explore the constraining power of bright standard sirens --…
A New Framework to Detect Multi-Messenger Signals from Bright Sporadic Stochastic Gravitational Wave Background
Hardik Jitendra Kuralkar, Mohit Raj Sah, Suvodip Mukherjee
The temporal dependence of the astrophysical stochastic gravitational-wave (GW) background (SGWB) in the hecto-hertz band brings a unique avenue to identify multi-messenger signals…
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…
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…
The First Model-Independent Chromatic Microlensing Search: No Evidence in the Gravitational Wave Catalog of LIGO-Virgo-KAGRA
Aniruddha Chakraborty, Suvodip Mukherjee
The lensing of Gravitational Waves (GWs) due to intervening matter distribution in the universe can lead to chromatic and achromatic signatures in the wave-optics and geometrical-o…
Multi-Messenger Cosmology: A Route to Accurate Inference of Dark Energy Beyond CPL Parametrization from XG Detectors
Samsuzzaman Afroz, Suvodip Mukherjee
One of the central challenges in modern cosmology is understanding the nature of dark energy and its evolution throughout the history of the Universe. Dark energy is commonly model…
Detecting Unmodeled, Source-dependent Signals in Gravitational Waves with SCoRe
Guillaume Dideron, Suvodip Mukherjee, Luis Lehner
New physics and systematic errors can lead to deviations between the models used to analyze gravitational wave data and the actual signal. Such deviations will generally be correla…
