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…

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…
