Radio and Gamma-Ray Timing of a Newly Discovered Millisecond Pulsar
L. Vleeschower, R. Sengar, L. Nieder +17
We report the discovery and timing of PSR J2147-3604, a fully recycled millisecond pulsar with a spin period of 3.2 ms, discovered in a reprocessing of the 350-MHz Green Bank North…
Quantum Evolution as a Square Root of the Master Equation
J. M. J. van Leeuwen
The analogy between the quantum evolution and that of the master equation is explored. By stressing the stochastic nature of quantum evolution a number of conceptual difficulties i…
Characterising the Apertif primary beam response
H. Dénes, K. M. Hess, E. A. K. Adams +27
Context. Phased Array Feeds (PAFs) are multi element receivers in the focal plane of a telescope that make it possible to form simultaneously multiple beams on the sky by combining…
Apertif, Phased Array Feeds for the Westerbork Synthesis Radio Telescope
W. A. van Cappellen, T. A. Oosterloo, M. A. W. Verheijen +87
We describe the APERture Tile In Focus (Apertif) system, a phased array feed (PAF) upgrade of the Westerbork Synthesis Radio Telescope which has transformed this telescope into a h…
Real-Time Dedispersion for Fast Radio Transient Surveys, using Auto Tuning on Many-Core Accelerators
Alessio Sclocco, Joeri van Leeuwen, Henri E. Bal +1
Dedispersion, the removal of deleterious smearing of impulsive signals by the interstellar matter, is one of the most intensive processing steps in any radio survey for pulsars and…
A LOFAR census of non-recycled pulsars: average profiles, dispersion measures, flux densities, and spectra
A. Bilous, V. Kondratiev, M. Kramer +24
We present first results from a LOFAR census of non-recycled pulsars. The census includes almost all such pulsars known (194 sources) at declinations and Galac…
A LOFAR census of millisecond pulsars
V. I. Kondratiev, J. P. W. Verbiest, J. W. T. Hessels +29
We report the detection of 48 millisecond pulsars (MSPs) out of 75 observed thus far using the LOFAR in the frequency range 110-188 MHz. We have also detected three MSPs out of nin…
Initial LOFAR observations of Epoch of Reionization windows: II. Diffuse polarized emission in the ELAIS-N1 field
V. Jelic, A. G. de Bruyn, M. Mevius +106
This study aims to characterise the polarized foreground emission in the ELAIS-N1 field and to address its possible implications for the extraction of the cosmological 21-cm signal…
A millisecond pulsar in a stellar triple system
S. M. Ransom, I. H. Stairs, A. M. Archibald +18
Gravitationally bound three-body systems have been studied for hundreds of years and are common in our Galaxy. They show complex orbital interactions, which can constrain the compo…
Detecting cosmic rays with the LOFAR radio telescope
P. Schellart, A. Nelles, S. Buitink +102
The low frequency array (LOFAR), is the first radio telescope designed with the capability to measure radio emission from cosmic-ray induced air showers in parallel with interferom…
The formation of the eccentric-orbit millisecond pulsar J1903+0327 and the origin of single millisecond pulsars
Simon Portegies Zwart, Ed van den Heuvel, Joeri van Leeuwen +1
The millisecond pulsar J1903+0327 is accompanied by an ordinary G-dwarf star in an unusually wide (\,days) and eccentric () orbit. The stand…
Pulsar Discovery by Global Volunteer Computing
B. Knispel, B. Allen, J. M. Cordes +37
Einstein@Home aggregates the computer power of hundreds of thousands of volunteers from 192 countries to "mine" large data sets. It has now found a 40.8 Hz isolated pulsar in radio…
The Allen Telescope Array: The First Widefield, Panchromatic, Snapshot Radio Camera for Radio Astronomy and SETI
Jack Welch, Don Backer, Leo Blitz +40
The first 42 elements of the Allen Telescope Array (ATA-42) are beginning to deliver data at the Hat Creek Radio Observatory in Northern California. Scientists and engineers are ac…
Arecibo Pulsar Survey Using ALFA: Probing Radio Pulsar Intermittency and Transients
J. S. Deneva, J. M. Cordes, M. A. McLaughlin +23
We present radio transient search algorithms, results, and statistics from the ongoing Arecibo Pulsar ALFA (PALFA) Survey of the Galactic plane. We have discovered seven objects by…
