Modelling energy-dependent pulsar light curves due to curvature radiation
(Sissa Medialab, 2017)
Pulsars emit pulsed emission across the entire electromagnetic spectrum and their light curve phenomenology is strongly dependent on energy. This is also true for the gamma-ray waveband. Continued detections by Fermi Large ...
Assessment of a statistical approach that facilitates the constraint of pulsar geometry via dualband light curve fitting
(Sissa Medialab, 2017)
The Large Area Telescope aboard the Fermi spacecraft has detected more than 200 γ-ray pulsars
since its launch in 2008. By concurrently fitting standard geometric model light curves onto Fermi
and radio data, researchers ...
The millisecond pulsar contribution to the rising positron fraction
(Sissa Medialab, 2016)
Pair cascades from millisecond pulsars (MSPs) may be a primary source of Galactic electrons and
positrons that contribute to the increase in positron flux above 10 GeV as observed by PAMELA
and AMS−02. The Fermi Large ...
High-energy emission from Black Widows and Redbacks
(Sissa Medialab, 2015)
A large number of new black widow and redback energetic millisecond pulsars with irradiated
stellar companions have been discovered through radio searches of unidentified Fermi sources.
We construct a 3D emission model ...
The aid of optical studies in understanding millisecond pulsar binaries
(Sissa Medialab, 2016)
A large number of new “black widow” and “redback” energetic millisecond pulsars with irradiated stellar companions have been discovered through radio and optical searches of unidentified
Fermi sources. Synchrotron emission, ...
High-energy emission properties of pulsars
(PoS, 2017)
The sheer number of new γ-ray pulsar discoveries by the Fermi Large Area Telescope since 2008,
combined with the quality of new multi-frequency data, has caused a revolution in the field of
high-energy rotation-powered ...
