2 The Pulsar Phenomenon 

Many of the basic observational facts about radio pulsars were established shortly after their discovery [75] by Jocelyn Bell and Anthony Hewish in 1967. In the intervening years, theoretical and observational progress has flourished. Although there are many remaining questions, particularly about the emission mechanism, the basic model has long been established beyond all reasonable doubt viz: Pulsars are rapidly rotating, highly magnetised neutron stars formed during the supernova explosions of massive () stars. In the following, we discuss the basic observational properties most relevant to this review.

• 2.1 The lighthouse model
• 2.2 Pulse Profiles
• 2.3 The Pulsar Distance Scale
• 2.4 Normal and Millisecond Pulsars
• 2.5 Pulsar Velocities
• 2.6 Going Further
