......@@ -42,13 +42,9 @@ searches and investigation of blind search methods. In addition, we were able to
data from the <i>Fermi</i>-LAT team, and search in longer data sets than ever before. In
combination, these improvements led to FGRP4 being our most sensitive survey to date.</p>
<p>We are very pleased to be able to announce the first set of results from FGRP4. Including the
discovery of PSR J1906+0722 at the beginning of this survey, these bring the total number of
gamma-ray pulsars discovered by our Einstein@Home volunteers to 21. You can find the details and
plots of all the new discoveries below!</p>
<p>With the publication in <a href="http://advances.sciencemag.org/content/4/2/eaao7228">Science Advances</a> of the discoveries of two millisecond pulsars (J1035-6720 and J1744-7619), we have now published all pulsar discoveries made during FGRP4. 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. To say "we couldn't have done it without you!" would be a terrible
