Query: The Einstein@Home Gamma-Ray Pulsar Survey II. Source Selection, Spectral
  Analysis and Multi-wavelength Follow-up   We report on the analysis of 13 gamma-ray pulsars discovered in the
Einstein@Home blind search survey using Fermi Large Area Telescope (LAT) Pass 8
data. The 13 new gamma-ray pulsars were discovered by searching 118
unassociated LAT sources from the third LAT source catalog (3FGL), selected
using the Gaussian Mixture Model (GMM) machine learning algorithm on the basis
of their gamma-ray emission properties being suggestive of pulsar
magnetospheric emission. The new gamma-ray pulsars have pulse profiles and
spectral properties similar to those of previously-detected young gamma-ray
pulsars. Follow-up radio observations have revealed faint radio pulsations from
two of the newly-discovered pulsars, and enabled us to derive upper limits on
the radio emission from the others, demonstrating that they are likely
radio-quiet gamma-ray pulsars. We also present results from modeling the
gamma-ray pulse profiles and radio profiles, if available, using different
geometric emission models of pulsars. The high discovery rate of this survey,
despite the increasing difficulty of blind pulsar searches in gamma rays,
suggests that new systematic surveys such as presented in this article should
be continued when new LAT source catalogs become available.
