ALMA observations of pulsars

Pulsars are strongly magnetised neutron stars where their fast rotation powers
the acceleration of particles in the magnetosphere and the emission of beamed
radiation from the radio to the gamma rays. One of the hottest topics in pulsar
astrophysics is whether the emission at different energies originates from different
population of particles, with different energy distributions, in different sites of
the magnetosphere, and whether this affects their complex multi-wavelength
spectra. It is clear that a full multi-wavelength coverage is essential to address
such issues. While other bands, have been explored, only now can we explore the
sub-mm with ALMA, a crucial range where coherent and incoherent emission
processes can coexist. In this talk I will describe the first ALMA observations of
pulsars and their implications.
