TL;DR: The detection of four nonrepeating radio transient events with millisecond duration in data from the 64-meter Parkes radio telescope in Australia indicates that these radio bursts had their origin outside the authors' galaxy, but it is not possible to tell what caused them.

TL;DR: This work reports the discovery of a 22-ms pulsar, PSR J0737–3039, which is a member of a highly relativistic double-neutron-star binary with an orbital period of 2.4 hours, which implies an order-of-magnitude increase in the predicted merger rate for double- NEUTron- star systems in the authors' Galaxy (and in the rest of the Universe).

TL;DR: The detection of the 2.8-second pulsar J0737–3039B as the companion to the 23-millisecond pulsars in a highly relativistic double neutron star system, allowing unprecedented tests of fundamental gravitational physics.

TL;DR: The International Pulsar Timing Array (IPTA) project as mentioned in this paper combines observations of pulsars from both northern and southern hemisphere observatories with the main aim of detecting ultra-low frequency (similar to 10(-9)-10(-8) Hz) gravitational waves.

TL;DR: In this paper, the authors used the current data from the European PTA to determine an upper limit on the GWB amplitude as a function of the unknown spectral slope with a Bayesian algorithm.
