New black widows and redbacks in the galactic field

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

There has recently been a large increase in the number of known eclipsing radio millisecond pulsars in the Galactic field, many of which are associated with Fermi γ-ray sources. All are in tight binaries (P b< 24hr) many of which are classical "black widows" with very low mass companions (M c<<0.1M ) but some are "redbacks" with probably non-degenerate low mass companions (M c∼0.2M ). I review the new discoveries, briefly discuss the distance uncertainties and the implications for high-energy emission.
