Understanding Pulsar Wind Nebulae with the SKA
Joseph D. Gelfand, C. -Y. Ng, B. Posselt +9
Produced by the interaction between the ``pulsar wind'' powered by the rotational energy of a neutron star and its surroundings, the study of pulsar wind nebulae (PWNe) provides vi…
The broadband spectral energy distribution of candidate neutrino blazars
Athira M Bharathan, C. S. Stalin, Markus Böttcher +3
Blazars, the jet dominated class of AGN comprising flat spectrum radio quasars (FSRQs) and BL Lac objects (BL Lacs) are now increasingly identified as potential sources of high ene…
Particle acceleration to PeV energies in Pulsar Wind Nebula: a two zone model
Gunindra Krishna Mahanta, Nilay Bhatt, Bitan Ghosal +1
\textit{PeVatrons} are the extreme galactic accelerators capable of producing PeV particles. Recent observation of Large High Altitude Air Shower Observatory have detected UHE phot…

Variability study of classical supergiant X-ray binary 4U 1907+09 using NuSTAR
Raj Kumar, Sayantan Bhattacharya, Sudip Bhattacharyya +1
We investigate the X-ray variability of the supergiant X-ray binary 4U 1907+09 using the new NuSTAR observation of 2024. The source had a relatively stable flux level during previo…
