“…RRATs are radio sources that emit detectable pulses only sporadically (McLaughlin et al 2006b). In most cases, their DMs suggest that they are Galactic sources and careful analyses of pulse arrival times have revealed periodicities within the range of pulsar periods (e.g., McLaughlin et al 2006b;Karako-Argaman et al 2015). Consequently, they are generally considered to be a class of Galactic pulsars with unusual emission properties.…”

We present a new model for the distribution of free electrons in the Galaxy, the Magellanic Clouds, and the intergalactic medium (IGM) that can be used to estimate distances to real or simulated pulsars and fast radio bursts (FRBs) based on their dispersion measure (DM). The Galactic model has an extended thick disk representing the so-called warm interstellar medium, a thin disk representing the Galactic molecular ring, spiral arms based on a recent fit to Galactic H II regions, a Galactic Center disk, and seven local features including the Gum Nebula, Galactic Loop I, and the Local Bubble. An offset of the Sun from the Galactic plane and a warp of the outer Galactic disk are included in the model. Parameters of the Galactic model are determined by fitting to 189 pulsars with independently determined distances and DMs. Simple models are used for the Magellanic Clouds and the IGM. Galactic model distances are within the uncertainty range for 86 of the 189 independently determined distances and within 20% of the nearest limit for a further 38 pulsars. We estimate that 95% of predicted Galactic pulsar distances will have a relative error of less than a factor of 0.9. The predictions of YMW16 are compared to those of the TC93 and NE2001 models showing that YMW16 performs significantly better on all measures. Timescales for pulse broadening due to interstellar scattering are estimated for (real or simulated) Galactic and Magellanic Cloud pulsars and FRBs.

“…New techniques of analysis for transient radio signals, applied to data of the Parkes Multibeam Survey, have led to the discovery of Rotating Radio Transients (RRATs) [99]: neutron stars which emit short (2-30 ms) radio pulses at intervals of minutes to hours. Their rotation periods, ranging from 0.4 to 7 s, have been inferred from the largest common divisors of the time intervals between bursts.…”

High-Energy Emission From Pulsars and Their Systems

X-ray emission is a common feature of all varieties of isolated neutron stars (INS) and, thanks to the advent of sensitive instruments with good spectroscopic, timing, and imaging capabilities, X-ray observations have become an essential tool in the study of these objects. Non-thermal X-rays from young, energetic radio pulsars have been detected since the beginning of X-ray astronomy, and the long-sought thermal emission from cooling neutron star's surfaces can now be studied in detail in many pulsars spanning different ages, magnetic fields, and, possibly, surface compositions. In addition, other different manifestations of INS have been discovered with X-ray observations. These new classes of high-energy sources, comprising the nearby X-ray Dim Isolated Neutron Stars, the Central Compact Objects in supernova remnants, the Anomalous X-ray Pulsars, and the Soft Gamma-ray Repeaters, now add up to several tens of confirmed members, plus many candidates, and allow us to study a variety of phenomena unobservable in "standard" radio pulsars.

“…Eatough et al (2009) applied a new interference removal technique to a small portion of the data and discovered a further four pulsars. In a further reanalysis, Keane et al found one fast radio burst (Keane et al 2012) and 10 rotating radio transients (Keane et al 2010) in addition to the 11 found originally by McLaughlin et al (2006). Mickaliger et al (2012) reported the discovery of the 34.5 ms 1 http://astro.phys.wvu.edu/GalacticMSPs 2 http://www.atnf.csiro.au/research/pulsar/psrcat binary pulsar J1725−3853 as well as four other millisecond pulsars.…”

We present timing observations of four millisecond pulsars discovered in the Parkes 20-cm multibeam pulsar survey of the Galactic plane. PSRs J1552−4937 and J1843−1448 are isolated objects with spin periods of 6.28 and 5.47 ms respectively. PSR J1727−2946 is in a 40-day binary orbit and has a spin period of 27 ms. The 4.43-ms pulsar J1813−2621 is in a circular 8.16-day binary orbit around a low-mass companion star with a minimum companion mass of 0.2 M ⊙ . Combining these results with detections from five other Parkes multibeam surveys, gives a well-defined sample of 56 pulsars with spin periods below 20 ms. We develop a likelihood analysis to constrain the functional form which best describes the underlying distribution of spin periods for millisecond pulsars. The best results were obtained with a log-normal distribution. A gamma distribution is less favoured, but still compatible with the observations. Uniform, power-law and Gaussian distributions are found to be inconsistent with the data. Galactic millisecond pulsars being found by current surveys appear to be in agreement with a log-normal distribution which allows for the existence of pulsars with periods below 1.5 ms.
