Pulsar surveys with the xNTD
We show that it is possible to perform an all-sky pulsar survey with the xNTD which is some 30 times more sensitive than the previous all-sky survey carried out using Parkes. The computing requirements dictate that this survey would be insensitive to millisecond pulsars with periods less than about 25 ms. However, the survey would detect some 1600 pulsars of which about half would be new discov...
متن کاملPulsar Surveys Present and Future: The Arecibo PALFA Survey and Projected SKA Survey
The Arecibo Pulsar-ALFA (PALFA) survey of the Galactic plane began in 2004 when the new ALFA (Arecibo L-band Feed Array) receiver was commissioned. It is slated to continue for the next 3-5 years and is expected to discover hundreds of new pulsars. We present the goals, progress, and recent discoveries of the PALFA survey. So far preliminary data processing has found 24 new pulsars, one of whic...
متن کاملPulsar glitch substructure and pulsar interiors
Pulsar timing at the Mt Pleasant observatory focused on Vela, which could be tracked for 18 hours of the day. These nearly continuous timing records extend over 24 years allowing a great insight into details of timing noise, micro glitches and other more exotic effects. It has been found that the spin up for the Vela pulsar occurs instantaneously to within the uncertainties of the data. The pot...
متن کاملPulsar Timing
The motivation for radio pulsar timing and its basic principles are reviewed. Present and future radio timing techniques and hardware are summarised and compared. The array of present timing programmes and their scientific goals are collated and described. Recent results and future prospects are discussed, with emphasis on multi-wavelength techniques where appropriate. Timing of radio pulsars a...
متن کاملFrom Pulsar Spin to Pulsar Wind: The Spectral Connection?
We present preliminary results from a systematic spectral study of pulsars and their wind nebulae using the Chandra X-Ray Observatory. The superb spatial resolution of Chandra allows us to differentiate the compact object’s spectrum from that of its surrounding nebulae. Specifically, for six Crab-like pulsars, we compare spectral fits of the averaged pulsar wind nebulae (PWN) emission to that o...
