PublicaciónPSR B0656+14: the unified outlook from the infrared to X-rays
We report detection of PSR B0656+14 with the Gran Telescopio Canarias in narrow optical F657, F754, F802, and F902 and near-infrared JHK s bands. The pulsar...

PublicaciónPSR J0210+5845: Ultra-wide binary pulsar with a B6 V main sequence star companion
We report on radio timing observations of PSR J0210+5845 that reveal large deviations from typical pulsar spin-down behaviour. We interpret these deviations as...

PublicaciónPSR 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...

PublicaciónRadio non-detection of SAX J1808.4-3658
We have observed the accreting millisecond X-ray pulsar SAX J1808.4-3658 in its current outburst (ATel #1728, #1732, #1733) in the radio band with the Australia...

CharlaReflections 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...
