October 2022 marks the first anniversary of our beloved project JETSET. On such a historic occasion, it’s my honour to look back on our activities…
For a visual understanding of the advanced techniques used to study the supermassive black hole SgrA*, see our Media page. Image reconstruction In 2022, the…
While the total mass of a binary neutron star (BNS) system can be reasonably well constrained based on the gravitational-wave (GW) signal measured by ground-based…
Magnetic reconnection and plasmoid formation in three-dimensional accretion flows around black holes
Magnetic reconnection is a sudden reconfiguration of the magnetic field lines that releases energy in the medium around the magnetic field. Magnetic reconnection is thought…
Imaging a supermassive black hole and extracting physical information requires good knowledge of both the gravitational and the astrophysical conditions near the black hole. When…
M87 has been the target of numerous astronomical observations across the electromagnetic spectrum, and very long baseline interferometry has resolved an edge-brightened jet. However, the…
In this paper, we develop a model to explain the flaring activity in the X-ray afterglows of gamma-ray bursts (GRBs) within the framework of slightly…
