Pulsar Observations of Extreme Scattering Events
W. A. Coles, M. Kerr, R. M. Shannon +17
Extreme scattering events (ESEs) in the interstellar medium (ISM) were first observed in regular flux measurements of compact extragalactic sources. They are characterized by a flu…
The High Time Resolution Universe Survey - XI. Discovery of five recycled pulsars and the optical detectability of survey white dwarf companions
S. D. Bates, D. Thornton, M. Bailes +20
We present the discovery of a further five recycled pulsar systems in the mid-Galactic latitude portion of the High Time Resolution Universe (HTRU) Survey. The pulsars have rotatio…
The low-frequency characteristics of PSR J0437-4715 observed with the Murchison Widefield Array
N. D. Ramesh Bhat, S. M. Ord, S. E. Tremblay +37
We report on the detection of the millisecond pulsar PSR J0437-4715 with the Murchison Widefield Array (MWA) at a frequency of 192 MHz. Our observations show rapid modulations of p…
Limitations in timing precision due to single-pulse shape variability in millisecond pulsars
R. M. Shannon, S. Osłowski, S. Dai +17
High-sensitivity radio-frequency observations of millisecond pulsars usually show stochastic, broadband, pulse-shape variations intrinsic to the pulsar emission process. These vari…
Timing, polarimetry and physics of the bright, nearby millisecond pulsar PSR J0437-4715 - a single-pulse perspective
S. Osłowski, W. van Straten, M. Bailes +2
Single pulses from radio pulsars contain a wealth of information about emission and propagation in the magnetosphere and insight into their timing properties. It was recently demon…
The High Time Resolution Universe Survey - IX: Polarimetry of long-period pulsars
C. Tiburzi, S. Johnston, M. Bailes +16
We present a polarimetric analysis of 49 long-period pulsars discovered as part of the High Time Resolution Universe (HTRU) southern survey. The sources exhibit the typical charact…
The High Time Resolution Universe Pulsar Survey VIII: The Galactic millisecond pulsar population
L. Levin, M. Bailes, B. R. Barsdell +17
We have used millisecond pulsars (MSPs) from the southern High Time Resolution Universe (HTRU) intermediate latitude survey area to simulate the distribution and total population o…
A Shapiro delay detection in the binary system hosting the millisecond pulsar PSR J1910-5959A
A. Corongiu, M. Burgay, A. Possenti +9
PSR J1910-5959A is a binary pulsar with a helium white dwarf companion located about 6 arcmin from the center of the globular cluster NGC6752. Based on 12 years of observations at…
The High Time Resolution Universe Survey VI: An Artificial Neural Network and Timing of 75 Pulsars
S. D. Bates, M. Bailes, B. R. Barsdell +19
We present 75 pulsars discovered in the mid-latitude portion of the High Time Resolution Universe survey, 54 of which have full timing solutions. All the pulsars have spin periods…
The High Time Resolution Universe Survey - V: Single-pulse energetics and modulation properties of 315 pulsars
S. Burke-Spolaor, S. Johnston, M. Bailes +11
We report on the pulse-to-pulse energy distributions and phase-resolved modulation properties for catalogued pulsars in the southern High Time Resolution Universe intermediate-lati…
The High Time Resolution Universe Pulsar Survey IV: Discovery and polarimetry of millisecond pulsars
M. J. Keith, S. Johnston, M. Bailes +13
We present the discovery of six millisecond pulsars (MSPs) in the High Time Resolution Universe (HTRU) survey for pulsars and fast transients carried out with the Parkes radio tele…
Transformation of a Star into a Planet in a Millisecond Pulsar Binary
M. Bailes, S. D. Bates, V. Bhalerao +15
Millisecond pulsars are thought to be neutron stars that have been spun-up by accretion of matter from a binary companion. Although most are in binary systems, some 30% are solitar…
