LIGO A: Detector Design and Science Prospects Beyond A+
L. Sun, K. Kuns, B. J. J. Slagmolen +1153
We present the LIGO A detector concept, an upgrade for the LIGO observatories based on room-temperature interferometers beyond the fifth observing run (O5). Building on th…
Oscillations of Dissipative Neutron Stars: The Impact of Hyperonic Reaction Rates
Suprovo Ghosh, Alexander Haber, Nils Andersson +1
Tidal excitations of stellar oscillation modes during binary neutron-star inspirals offer a powerful probe of the composition of dense matter at supranuclear densities. Chemical eq…
Dynamical tidal response of neutron stars via scattering amplitudes
M. V. S. Saketh, Suprovo Ghosh, Nils Andersson
A key challenge of gravitational-wave physics is distinguishing the nature of compact objects in binary coalescences, in particular whether they are black holes or neutron stars. N…
The tidal response of a relativistic star
Nils Andersson, Rhys Counsell, Fabian Gittins +1
We develop a fully relativistic approach for determining the response of a compact star to a time/frequency dependent (tidal) environment. The strategy involves matching the soluti…
Tidal heating in binary inspiral of strange quark stars
Suprovo Ghosh, José Luis Hernández, Bikram Keshari Pradhan +3
We investigate tidal heating associated with the binary inspiral of strange quark stars and its impact on the resulting gravitational wave signal. Tidal heating during the merger o…
Tidal dissipation in binary neutron star inspirals from hyperon bulk viscosity: Phase modeling and parameter estimation bias
Suprovo Ghosh, Samanwaya Mukherjee, Sukanta Bose +1
During the inspiral of a binary neutron star, viscous processes in the neutron star matter can damp out the tidal energy induced by its companion and convert it to thermal energy.…
Investigating tidal heating in neutron stars via gravitational Raman scattering
M. V. S. Saketh, Zihan Zhou, Suprovo Ghosh +2
We present a scattering amplitude formalism to study the tidal heating effects of nonspinning neutron stars incorporating both worldline effective field theory and relativistic ste…
Tidal heating as a direct probe of strangeness inside neutron stars
Suprovo Ghosh, Bikram Keshari Pradhan, Debarati Chatterjee
It has been discussed whether viscous processes in neutron star matter during a binary inspiral can damp out the tidal energy induced by the companion and heat up the star. Earlier…
R-modes as a New Probe of Dark Matter in Neutron Stars
Swarnim Shirke, Suprovo Ghosh, Debarati Chatterjee +2
In this work, we perform the first systematic investigation of effects of the presence of dark matter on -mode oscillations in neutron stars (NSs). Using a self-interacting dark…
Universal relations to measure neutron star properties from targeted r-mode searches
Suprovo Ghosh
R-mode oscillations of rotating neutron stars(NS) are promising candidates for continuous gravitational wave (GW) observations. In our recent work, we derived universal relations o…
Theoretical and Experimental Constraints for the Equation of State of Dense and Hot Matter
Rajesh Kumar, Veronica Dexheimer, Johannes Jahan +57
This review aims at providing an extensive discussion of modern constraints relevant for dense and hot strongly interacting matter. It includes theoretical first-principle results…
Constraining the equation of state of hybrid stars using recent information from multidisciplinary physics
Swarnim Shirke, Suprovo Ghosh, Debarati Chatterjee
At the ultra-high densities existing in the core of neutron stars, it is expected that a phase transition from baryonic to deconfined quark matter may occur. Such a phase transitio…
Relativistic correction to the r-mode frequency in light of multi-messenger constraints
Suprovo Ghosh, Dhruv Pathak, Debarati Chatterjee
R-mode oscillations of rotating neutron stars are promising candidates for continuous gravitational wave (GW) observations. The r-mode frequencies for slowly rotating Newtonian sta…
Multi-physics constraints at different densities to probe nuclear symmetry energy in hyperonic neutron stars
Suprovo Ghosh, Bikram Keshari Pradhan, Debarati Chatterjee +1
The appearance of strangeness in the form of hyperons within the inner core of neutron stars is expected to affect its detectable properties such as its global structure or gravita…
