The predicted nature of the candidate redback pulsar 4FGL J2039.5-56.17 was recently confirmed by the discovery of $\gamma$-ray millisecond pulsations (Clark et al. 2020, hereafter Paper I), which identify this $\gamma$-ray source as PSR J2039-5617. We observed 4FGL 2039.5-5617 with the Parkes radio telescope in 2016 and 2019. We detect radio pulsations at 1.4 GHz and 3.1 GHz, at the 2.6 ms period discovered in $\gamma$-rays, and also at 0.7 GHz in one 2015 archival observation. In all bands… 

Luminous Optical and X-Ray Flaring of the Putative Redback Millisecond Pulsar 1FGL J0523.5–2529

Several redback and black widow millisecond pulsar binaries have episodes of flaring in X-rays and optical. We initially detected such behavior from the Fermi selected redback candidate 1FGL

Discovery of a New Redback Millisecond Pulsar Candidate: 4FGL J0940.3–7610

We have discovered a new candidate redback millisecond pulsar binary near the center of the error ellipse of the bright unassociated Fermi-LAT γ-ray source 4FGL J0940.3–7610. The candidate

On the origin of the gamma-ray emission from Omega Centauri: millisecond pulsars and dark matter annihilation

We explore two possible scenarios to explain the observed γ-ray emission associated with the atypical globular cluster ω-Centauri: emission from millisecond pulsars (MSP) and dark matter (DM)

Einstein@Home discovery of the gamma-ray millisecond pulsar PSR J2039–5617 confirms its predicted redback nature

The Fermi Large Area Telescope gamma-ray source 3FGL J2039.6–5618 contains a periodic optical and X-ray source that was predicted to be a ‘redback’ millisecond pulsar (MSP) binary system. However,

Implementation of a goodness-of-fit test for finding optimal concurrent radio and {\gamma}-ray pulsar light curves

Since the launch of the Fermi Large Area Telescope in 2008 the number of known ${\gamma}$-ray pulsars has increased immensely to over 200, many of which are also visible in the radio and X-ray bands.

The high-energy emission of millisecond pulsars

This chapter provides a phenomenological appraisal of the high-energy emission of millisecond pulsars. We comment on some of their properties as a population, as well as consider the especial cases
