Pulsar wind nebulae (PWNe) are one of the most energetic galactic sources with bright emissions from radio waves to very high-energy gamma-rays. We perform wideband X-ray spectroscopy of four energetic PWNe, N157B, PSR J1813-1749, PSR J1400-6325, and

Giant radio pulses (GRPs) are sporadic bursts emitted by some pulsars, lasting a few microseconds. GRPs are hundreds to thousands of times brighter than regular pulses from these sources. The only GRP-associated emission outside radio wavelengths is

Probing the star formation origin of gamma rays from 3FHL J1907.0+0713

Autor: Pooja Bhattacharjee, Pratik Majumdar, Y. Fukui, Ryo Yamazaki, Lab Saha, Tulun Ergin, Hidetoshi Sano, Shuta J. Tanaka

Star-forming (SF) regions embedded inside giant molecular clouds (GMCs) are potential contributors to Galactic gamma rays. The gamma-ray source 3FHL J1907.0+0713 is detected with a significance of roughly 13$\sigma$ in the 0.2 $-$ 300 GeV energy rang
