Description
TeV halos have drawn extensive attention since the first discovery from the HAWC observatory. These huge gamma-ray structures around pulsars provide important information about the particle acceleration and propagation in pulsar-powered systems, and probe the characteristics of the ambient interstellar environments. With HAWC, LHAASO, and other ground-based and space-borne gamma-ray instruments, more TeV halos, more generally, pulsar halos, are discovered and studied at different energies. In this contribution, I will summarize the discoveries of the first TeV halos and discuss the future prospects.
