Mirages and Large TeV Halo-Pulsar Offsets from Cosmic-Ray Propagation

Le résumé fourni par la source

The study of extended γ-ray sources usually assumes symmetric diffusion of cosmic rays. However, recent observations of multiple sources near single pulsars and significant offsets between TeV halo centroids and their parent pulsars suggest that this assumption is overly simplistic. In this Letter, we demonstrate that asymmetric propagation of cosmic rays near their accelerators may create multiple TeV sources instead of a single symmetric source. This mechanism also explains the large offsets between TeV halo centroids and their parent pulsars. We demonstrate that several perplexing detected sources can be naturally interpreted without invoking additional invisible accelerators.
