The 4th Einstein@Home survey for gamma-ray pulsars, or “FGRP4”, using data from NASA’s Fermi Gamma-ray Space Telescope is currently nearing completion. This survey has incorporated many new advances that we learned during our previous investigation of blind search methods. In addition, we were able to utilize the superior “Pass 8” data from the Fermi-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.
We are very pleased to be able to announce a first set of results from FGRP4 - the discovery of 13 new gamma-ray pulsars!

This brings the total number of gamma-ray pulsars discovered by Einstein@Home volunteers to 18. Further details and plots of all the new discoveries are available here!
We are currently 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. For now, as FGRP4 begins to wind down, we are excited to announce the start of our next survey, “FGRPB1”. The “B” here stands for “binary”; for the first time, Einstein@Home will be used to also search for gamma-ray pulsars in orbits with companion stars.
Thank you to everyone participating in Einstein@Home, your contribution has enabled these fantastic discoveries!
