The Parkes multibeam pulsar survey – IV. Discovery of 180 pulsars and parameters for 281 previously known pulsars

TLDR
The Parkes multibeam pulsar survey has led to the discovery of more than 700 radio pulsars as discussed by the authors, including two pulsars with rotational periods of less than 6 s and a third pulsar with a period of 1.8 ms.
Abstract
The Parkes multibeam pulsar survey has led to the discovery of more than 700 pulsars. In this paper, we provide timing solutions, flux densities and pulse profiles for 180 of these new discoveries. Two pulsars, PSRs J1736−2843 and J1847−0130, have rotational periods P > 6 s and are therefore among the slowest rotating radio pulsars known. Conversely, with P = 1.8 ms, PSR J1843−1113 has the third-shortest period of pulsars currently known. This pulsar and PSR J1905+0400 (P = 3.8 ms) are both solitary. We also provide orbital parameters for a new binary system, PSR J1420−5625, which has P = 34 ms, an orbital period of 40 d and a minimum companion mass of 0.4 solar masses. The 10 ◦ -wide strip along the Galactic plane that was surveyed is known to contain 264 radio pulsars that were discovered prior to the multibeam pulsar survey. We have redetected almost all of these pulsars and provide new dispersion measure values and flux densities at 20 cm for the redetected pulsars.

Pulsar distances and the galactic distribution of free electrons

TL;DR: In this paper, the authors present a quantitative model for the Galactic free electron distribution, which abandons the assumption of axisymmetry and explicitly incorporates spiral arms; their shapes and locations are derived from existing radio and optical observations of H II regions.

The Parkes multi-beam pulsar survey - I. Observing and data analysis systems, discovery and timing of 100 pulsars

TL;DR: The survey is proving to be extremely successful, with more than 600 pulsars discovered so far as discussed by the authors, and the number of newly discovered pulsars tend to be young, distant and of high radio luminosity, which is a valuable sample for studies of pulsar emission properties, the Galactic distribution and evolution of pulsars, and as probes of interstellar medium properties.

The spectrum of clipped noise

TL;DR: In this paper, the authors calculate the intensity spectrum to be expected for clipped (also called "limited") noise, where the limiting amplitude is very small compared to the rms amplitude before clipping.
