Gamma Ray Bursts from Magnetic Reconnection in Cosmic Strings Wakes
Dilip Kumar, Bijita Bose, Soma Sanyal
Magnetic reconnection in magnetized wakes of cosmic strings results in the release of a large amount of energy. This energy is released in a short period of time. In this work, we…
Effect of Noncommutative Geometry on Accretion Disks around RGI-Schwarzschild Black Hole
Dilip Kumar
In this study, we explore the combined effects of quantum gravity induced by non-commutativity and scale-dependent gravitational coupling on the thermal properties of the thin accr…
Magnetic field amplification and decay in cosmic string wakes
Deepanshu Bisht, Dilip Kumar, Soumen Nayak +1
We do a detailed study on vortex formation in a magnetized plasma within the spacetime of a moving cosmic string using analytical and numerical methods. The conical spacetime aroun…
Synchrotron radiation from cosmic string wakes
Dilip Kumar, Soumen Nayak, Soma Sanyal
Magnetic fields can be generated in cosmic string wakes due to the Biermann mechanism in the presence of neutrino inhomogeneities. As the cosmic string moves through the plasma the…
