Colloquium - Gamma-ray emission from pulsars and their environments: an experimental perspective

Submitter: Roberta Zanin
Description: Pulsars and their synchrotron nebulae have been extensively observed in the gamma-ray energy band for the last 15 years. The data taken with the Fermi satellite increased the number of known gamma-ray emitting pulsars by one order of magnitude, being currently about 200. On the other hand, the imaging Cherenkov telescopes proved that pulsar wind nebulae are the most common class of sources radiating in the very high energy (VHE; >100 GeV) sky. For the first time population studies are within the reach providing an unprecedented opportunity to test the pulsed and nebular emission models on the market. This vast variety of high-precision spectral and morphological measurements along with the computing technical advances that allowed for deep CPU-consuming simulations led to a significant progress in the understanding of the radiation and particle acceleration mechanisms at work. In this contribution, I will review the latest, and most significant experimental gamma-ray results that led to the construction of a new view of the pulsar magnetosphere and its surroundings. In addition, I will summarize the perspectives in this field for the future gamma-ray instruments, mainly the Cherenkov Telescope Array.
