These amount to 19 new pulsars, almost a third of all gamma-ray pulsars to be discovered in blind searches.</p> -<p>Currently we are working very hard to study all of the results from FGRP4, and we are hoping to - present these in a series of papers in the near future. </p> +<p>Of course, this does not mean that our gamma-ray pulsation searches on Einstein@Home are coming to an end! The Fermi mission continues to find new gamma-ray sources for us to target, so we are very optimistic that we will be able to build upon the success of FGRP4 in the near future. Currently FGRP5 is searching for pulsars in gamma-ray sources detected near the Galactic Centre, while FGRPB1 is searching for pulsations from binary millisecond pulsar candidates. </p> <p>As always, we are extremely grateful to all of our volunteers, especially those whose computers contributed to these new discoveries.
