From Paulo Freire for the GWA14 conference
In this talk I present some recent pulsar timing experiments for double neutron stars that test general relativity's quadrupolar gravitational wave emission formula with unprecedented precision. I then present the results of timing of millisecond pulsar - white dwarf systems that severely constrain the emission of dipolar gravitational waves (DGW) for a wide range of neutron star masses. Apart from constraining (and in some cases excluding) alternative theories of gravity that predict DGW emission, these results reinforce our confidence in the templates being used to search for the GW signal of NS-NS and NS-BH inspiral events in the advanced LIGO and Virgo detectors.
