    PSR J1744-3922: Hint of a New Binary Pulsar Class
    Standard binary evolution models of pulsars in very circular orbits can explain systems with lighter companions and weaker magnetic fields: they are descended...

    Reflections on the discovery of pulsars
    In this talk I will summarise the events that led to the discovery of the first four pulsars, recount several instances where pulsars were almost discovered and...
