General relativistic hydrodynamic simulations of binary strange star mergers
Francesco Grippa, Aviral Prakash, Domenico Logoteta +2
We perform fully general-relativistic simulations of binary strange star mergers considering two different approaches for thermal effects. The first uses a cold equation of state (…
Do black holes remember what they are made of?
Harshraj Bandyopadhyay, David Radice, Aviral Prakash +4
We study the ringdown signal of black holes formed in prompt-collapse binary neutron star mergers. We analyze data from numerical relativity simulations. We show that the $(\e…
Detectability of QCD phase transitions in binary neutron star mergers: Bayesian inference with the next generation gravitational wave detectors
Aviral Prakash, Ish Gupta, Matteo Breschi +5
We study the detectability of postmerger QCD phase transitions in neutron star binaries with next-generation gravitational-wave detectors Cosmic Explorer and Einstein Telescope. We…
Turbulent boundary layer with strong favorable pressure gradient and curvature effects: Streamline coordinate and scaling analysis
Aviral Prakash, Riccardo Balin, John A. Evans +1
Direct numerical simulation (DNS) of a turbulent boundary layer over the Gaussian (Boeing) bump is performed. This boundary layer exhibits a series of adverse and favorable pressur…

Optimal Clipping of Structural Subgrid Stress Closures for Large Eddy Simulation
Aviral Prakash, Kenneth E. Jansen, John A. Evans
Structural subgrid stress models for large eddy simulation often allow for backscatter of energy from unresolved to resolved turbulent scales, but excessive model backscatter can e…

Using 250 neutron star merger simulations with microphysics, we explore for the first time the role of nuclear incompressibility in the prompt collapse threshold for binaries with…
Numerical relativity simulations of prompt collapse mergers: threshold mass and phenomenological constraints on neutron star properties after GW170817
