Status and Prospects of Fermi LAT Pulsar Blind Searches
P. M. Saz Parkinson (for the Fermi-LAT Collaboration)
TL;DR
Fermi LAT blind searches have discovered 24 gamma-ray pulsars, mostly radio-quiet, with ongoing efforts to find more among unassociated sources and challenges ahead.
Contribution
This paper summarizes recent Fermi LAT blind search results, including the discovery of a new Geminga-like pulsar, and discusses future challenges and prospects.
Findings
Discovered 24 gamma-ray pulsars in the first year
Identified a new Geminga-like pulsar, PSR J0734-1559
Most pulsars remain undetected in radio despite deep searches
Abstract
Blind Searches of Fermi Large Area Telescope (LAT) data have resulted in the discovery of 24 gamma-ray pulsars in the first year of survey operations, most of which remain undetected in radio, despite deep radio follow-up searches. I summarize the latest Fermi LAT blind search efforts and results, including the discovery of a new Geminga-like pulsar, PSR J0734-1559. Finally, I discuss some of the challenges faced in carrying out these searches into the future, as well as the prospects for finding additional pulsars among the large number of LAT unassociated sources.
