NuSTAR and Chandra Observations of Galactic center non-thermal X-ray Filament G0.13-0.11: a Pulsar Wind Nebula Driven Magnetic Filament
Abstract
A unique and striking phenomenon in the Galactic center region is the existence of more than one hundred non-thermal radio filaments extending up to tens of parsecs, as recently revealed by MeerKAT. Similar filamentary structures at smaller spatial scales have also been detected in the X-ray energy bands. The origin and formation of of these filaments have been long-standing questions for decades. In this talk I will discuss a unique non-thermal X-ray filament, G0.13-0.11, which is located adjacent to the Radio arc. Chandra revealed its elongated X-ray structure slighted bending towards the Radio arc. A pulsar candidate is detected in the middle of the filaments, with a tail of diffuse X-ray emission on one side of the filament. The filament was also detected by NuSTAR up to 79 keV, with the hard X-ray centroid consistent with the pulsar candidate. The nature of this system is most likely a pulsar wind nebula colliding into a highly organized magnetic structure. Lastly, I will also discuss a project to reveal the source nature for all the Galactic center X-ray filaments.
