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…
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…
Prospects for cosmological constraints using gravitational wave memory
Indranil Chakraborty, Susmita Jana, S. Shankaranarayanan
The ΛCDM model has long served as a robust and predictive framework for cosmology, successfully explaining a wide range of observations, including the accelerated expansion of the…
Transient electromagnetic sources can detect solitary black holes in Milky Way galaxy
Susmita Jana, Rituparno Goswami, S. Shankaranarayanan +1
The Milky Way galaxy is estimated to host up to a billion stellar-mass solitary black holes (BHs). The number and distribution of BH masses can provide crucial information about th…
