dc.description.abstract | Radio timing observations of millisecond pulsars (MSPs) in support of Fermi LAT
observations of the gamma-ray sky enhance the sensitivity of high-energy pulsation searches. With
contemporaneous ephemerides we have detected gamma-ray pulsations from PSR B1937+21, the
first MSP ever discovered, and B1957+20, the first known black-widow system. The two MSPs
share a number of properties: they are energetic and distant compared to other gamma-ray MSPs,
and both of them exhibit aligned radio and gamma-ray emission peaks, indicating co-located
emission regions in the outer magnetosphere of the pulsars. However, radio observations are also
crucial for revealing MSPs in Fermi unassociated sources. In a search for radio pulsations at the
position of such unassociated sources, the Nançay Radio Telescope discovered two MSPs, PSRs
J2017+0603 and J2302+4442, increasing the sample of known Galactic disk MSPs. Subsequent
radio timing observations led to the detection of gamma-ray pulsations from these two MSPs as well.
We describe multiwavelength timing and spectral analysis of these four pulsars, and the modeling
of their gamma-ray light curves in the context of theoretical models | en_US |
