Description
With a growing number of gamma-ray emitting millisecond pulsars (MSPs) discovered by Fermi and by combining multi-wavelength observing facilities, it is now possible to study their properties as a population. One of the successes is the discovery of gamma-ray emitting compact MSP binaries known as black-widow and redback systems and this opens a new window to study pulsars and their evolution. I will discuss how multi-wavelength observations reveal a new population of compact MSP binaries that provides new insight into MSP's emission mechanisms and the physics of compact objects. In particular, I will summarize some recent results of our optical and hard X-ray observing campaigns of gamma-ray emitting black-widows and redbacks, and will also discuss the implications to their evolution.
