GeV emission around SS 433 with 17 years Fermi-LAT observation
Qiwang Sun, Dmitry Khangulyan, Jiren Liu +1
We present an analysis of 17 years of Fermi-LAT observations of the microquasar SS~433. We detect four GeV sources in the region: a newly identified source, PS J1910+0550, located…

An extreme particle accelerator powered by pulsar PSR J1849-0001
The LHAASO Collaboration
Pulsar wind nebulae (PWNe) are bubbles of relativistic particles, powered by the rotational energy loss of the central pulsars. The Crab Nebula, powered by the Milky Way's most ene…

A mechanism-independent methodology for modeling γ-ray phaseograms of pulsars in the framework of north-south symmetry
Paul K. H. Yeung, Dmitry Khangulyan, Takayuki Saito
Fermi-LAT observations revealed that each GeV phase-folded light-curve (aka. phaseogram) of the Crab, Geminga, Dragonfly and Vela pulsars consists of two pulses (P1 & P2) and a "Br…
