Tight multimessenger constraints on the neutron star equation of state from GW170817 and a forward model for kilonova light-curve synthesis [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2021
We present a rapid analytic framework for predicting kilonova light curves following neutron star (NS) mergers, where the main input parameters are binary-based properties measurable by gravitational wave detectors (chirp mass and mass ratio, orbital ...

Microfluidics: A Novel Approach for Dehydration Protein Droplets

open access: yesBiosensors, 2021
The equation of state of colloids plays an important role in the modelling and comprehension of industrial processes, defining the working conditions of processes such as drying, filtration, and mixing.

Kinetic equation consistent with the equation of state of nuclear matter [PDF]

open access: yes, 1998
A kinetic equation which combines the quasiparticle drift of Landau's equation with a dissipation governed by a nonlocal and noninstant scattering integral in the spirit of Snider's equation for gases is derived.

Radial Oscillations in Neutron Stars from Unified Hadronic and Quarkyonic Equation of States

open access: yesGalaxies, 2023
We study radial oscillations in non-rotating neutron stars by considering the unified equation of states (EoSs), which support the 2 M⊙ star criterion.

Uncertainty quantification for a multi-phase carbon equation of state model

open access: yesJournal of Applied Physics, 2022
Many physics models have tunable parameters that are calibrated by matching the model output to experimental or calculated data. However, given that calibration data often contain uncertainty and that different model parameter sets might result in a very

Equation of state from lattice QCD [PDF]

open access: yes, 2005
Recent results on the equation of state from lattice QCD are reviewed. The lattice technique and previous results are shortly discussed. New results for physical quark masses and two sets of lattice spacings are presented.

Induced gravitational wave interpretation of PTA data: a complete study for general equation of state [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics
We thoroughly study the induced gravitational wave interpretation of the possible gravitational wave background reported by PTA collaborations, considering the unknown equation of state w of the early universe.

Neural simulation-based inference of the neutron star equation of state directly from telescope spectra [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics
Neutron stars provide a unique opportunity to study strongly interacting matter under extreme density conditions. The intricacies of matter inside neutron stars and their equation of state are not directly visible, but determine bulk properties, such as ...

An inflationary equation-of-state

open access: yesInternational Journal of Modern Physics D, 2023
In this paper, we have studied inflationary paradigm through an inflationary equation-of-state. With a single parameter equation-of-state as a function of the scalar field responsible for accelerated expansion, we find an observationally viable model satisfying all the constraints as laid down by the recent observations.
