MRI turbulence in vertically stratified accretion discs at large magnetic Prandtl numbers

Loren E. Held, George Mamatsashvili, Martin E. Pessah

The discovery of the first binary neutron star merger, GW170817, has spawned a plethora of global numerical relativity simulations. These simulations are often ideal (with dissipat…

Meterwavelength Single-pulse Polarimetric Emission Survey. VI. Towards understanding the Phenomenon of Pulsar Polarization in Partially Screened Vacuum Gap model

Dipanjan Mitra, George I. Melikidze, Rahul Basu

We have observed 123 pulsars with periods longer than 0.1 seconds in the Meterwavelength Single-pulse Polarimetric Emission Survey. In this work a detailed study of polarization be…

GRANDMA and HXMT Observations of GRB 221009A -- the Standard-Luminosity Afterglow of a Hyper-Luminous Gamma-Ray Burst

D. A. Kann, S. Agayeva, V. Aivazyan +113

GRB 221009A is the brightest Gamma-Ray Burst (GRB) detected in more than 50 years of study. In this paper, we present observations in the X-ray and optical domains after the GRB ob…

Estimating the evolution of Sparks in Partially Screened Gap of Pulsars from Subpulse Drifting

Rahul Basu, Dipanjan Mitra, George I. Melikidze

A novel scheme has been developed to show that the observed phase behaviour associated with subpulse drifting from two pulsars, J10343224 and J17202933, can be used to obtain…

The optical behaviour of BL Lacertae at its maximum brightness levels: a blend of geometry and energetics

C. M. Raiteri, M. Villata, S. G. Jorstad +13

In 2021 BL Lacertae underwent an extraordinary activity phase, which was intensively followed by the Whole Earth Blazar Telescope (WEBT) Collaboration. We present the WEBT optical…

Evidence for Coherent Curvature Radiation in PSR J16450317 with Disordered Distribution of Polarization Position Angle

Dipanjan Mitra, George I. Melikidze, Rahul Basu

The diverse polarization properties in pulsars are in conflict with applying a unique emission mechanism to the population. The polarization position angle (PPA) traverse in most p…
