Defining eccentricity for gravitational wave astronomy
Md Arif Shaikh, Vijay Varma, Harald P. Pfeiffer +2
Eccentric compact binary mergers are significant scientific targets for current and future gravitational wave observatories. To detect and analyze eccentric signals, there is an in…
Carter-Penrose diagrams for emergent spacetime in axisymmetrically accreting black hole systems
Susovan Maity, Md Arif Shaikh, Pratik Tarafdar +1
For general relativistic, inviscid, axisymmetric flow around Kerr black hole one may choose different flow thickness. The stationary flow equations can be solved using methods of d…
Deep Learning with Quantized Neural Networks for Gravitational Wave Forecasting of Eccentric Compact Binary Coalescence
Wei Wei, E. A. Huerta, Mengshen Yun +5
We present the first application of deep learning forecasting for binary neutron stars, neutron star - black hole systems, and binary black hole mergers that span an eccentricity r…
Relativistic sonic geometry for isothermal accretion in the Kerr metric
Md Arif Shaikh
We linearly perturb advective isothermal transonic accretion onto rotating astrophysical black holes to study the emergence of the relativistic acoustic spacetime and to investigat…
Relativistic sonic geometry for isothermal accretion in the Schwarzschild metric
Md Arif Shaikh, Ivleena Firdousi, Tapas K. Das
In this work, we perform linear perturbation on general relativistic isothermal accretion onto a non-rotating astrophysical black hole to study the salient features of the correspo…
Acoustic geometry obtained through the perturbation of the Bernoulli's constant
Satadal Datta, Md Arif Shaikh, Tapas K Das
For accretion onto astrophysical black holes, we demonstrate that linear perturbation of Bernoulli's constant defined for an inviscid irrotational adiabatic flow of perfect ideal f…
