Pulsar science with the CHIME telescope
Cherry Ng
The CHIME telescope (the Canadian Hydrogen Intensity Mapping Experiment) recently built in Penticton, Canada, is currently being commissioned. Originally designed as a cosmology ex…
Algorithms for FFT Beamforming Radio Interferometers
Kiyoshi W. Masui, J. Richard Shaw, Cherry Ng +3
Radio interferometers consisting of identical antennas arranged on a regular lattice permit fast Fourier transform beamforming, which reduces the correlation cost from $\mathcal{O}…
Gamma-ray pulsars with Fermi
David A. Smith, Lucas Guillemot, Matthew Kerr +2
In 8 years of operation, the Large Area Telescope (LAT) on the Fermi satellite has impacted our understanding of gamma-ray pulsars dramatically. The LAT now sees over two hundred p…
Formation of Double Neutron Star Systems
T. M. Tauris, M. Kramer, P. C. C. Freire +11
Double neutron star (DNS) systems represent extreme physical objects and the endpoint of an exotic journey of stellar evolution and binary interactions. Large numbers of DNS system…
Chandra Phase-Resolved Spectroscopy of the High Magnetic Field Pulsar B1509-58
Chin-Ping Hu, C. -Y. Ng, J. Takata +2
We report on a timing and spectral analysis of the young, high magnetic field rotation-powered pulsar (RPP) B1509-58 using Chandra continuous-clocking mode observation. The pulsar'…
CHIME FRB: An application of FFT beamforming for a radio telescope
C. Ng, K. Vanderlinde, A. Paradise +11
We have developed FFT beamforming techniques for the CHIME radio telescope, to search for and localize the astrophysical signals from Fast Radio Bursts (FRBs) over a large instanta…
