Pulse Broadening Measurements from the Galactic Center Pulsar J1745--2900
L. G. Spitler, K. J. Lee, R. P. Eatough +11
We present temporal scattering measurements of single pulses and average profiles of PSR J1745--2900, a magnetar recently discovered only 3 arcsec away from Sagittarius A* (Sgr A*)…
The Angular Broadening of the Galactic Center Pulsar SGR J1745-29: A New Constraint on the Scattering Medium
Geoffrey C. Bower, Adam Deller, Paul Demorest +6
The pulsed radio emission from the Galactic Center (GC) magnetar SGR J1745-29 probes the turbulent, magnetized plasma of the GC hyperstrong scattering screen through both angular a…
High-Angular-Resolution and High-Sensitivity Science Enabled by Beamformed ALMA
Vincent Fish, Walter Alef, James Anderson +66
An international consortium is presently constructing a beamformer for the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile that will be available as a facility instrum…
A strong magnetic field around the supermassive black hole at the centre of the Galaxy
R. P. Eatough, H. Falcke, R. Karuppusamy +20
The centre of our Milky Way harbours the closest candidate for a supermassive black hole. The source is thought to be powered by radiatively inefficient accretion of gas from its e…
The Northern High Time Resolution Universe Pulsar Survey I: Setup and initial discoveries
Ewan D. Barr, David J. Champion, Michael Kramer +10
We report on the setup and initial discoveries of the Northern High Time Resolution Universe survey for pulsars and fast transients, the first major pulsar survey conducted with th…
Einstein@Home Discovery of 24 Pulsars in the Parkes Multi-beam Pulsar Survey
B. Knispel, R. P. Eatough, H. Kim +18
We have conducted a new search for radio pulsars in compact binary systems in the Parkes multi-beam pulsar survey (PMPS) data, employing novel methods to remove the Doppler modulat…
