Integrated cosmological memory: A dark-siren method to probe dark energy
Indranil Chakraborty, Sayantan Ghosh, Susmita Jana +2
Gravitational-wave (GW) cosmology is currently bottlenecked by the scarcity of electromagnetic counterparts for bright sirens and the systematic uncertainties of galaxy catalogs fo…
Prospects for cosmological constraints using gravitational wave memory
Indranil Chakraborty, Susmita Jana, S. Shankaranarayanan
The paper proposes using the integrated gravitational‑wave memory signal from distant binary mergers as a new cosmological probe, showing that its amplitude is strongly sensitive t…
Exact, non-singular black holes from a phantom DBI Field as primordial dark matter
Tausif Parvez, S. Shankaranarayanan
We present the first exact, non-singular black hole solution in General Relativity sourced by a Dirac-Born-Infeld (DBI) scalar field. Crucially, the solution is exclusively support…
Disformal interactions in the Dark Sector: From driving Early Dark Energy to confronting cosmological tensions
Pulkit Bansal, Joseph P. Johnson, S. Shankaranarayanan
The CDM model faces significant challenges, including an incomplete understanding of the dark sector and persistent tensions in the Hubble constant and the clustering amplitude…
A non-local origin for massive gravity and late-time acceleration
Susobhan Mandal, S. Shankaranarayanan
The accelerated expansion of the universe poses a significant challenge to General Relativity. Non-local modifications to gravity have emerged as a compelling class of theories to…
Signatures of asymmetry: Gravitational wave memory and the parity violation
Indranil Chakraborty, Susmita Jana, S. Shankaranarayanan
Einstein's equivalence principle suggests a deep connection between matter and spacetime, prompting the question: if matter violates parity, must gravity? This letter explores the…
