Dense magnetized plasma associated with a fast radio burst
Kiyoshi Masui, Hsiu-Hsien Lin, Jonathan Sievers +15
Fast Radio Bursts are bright, unresolved, non-repeating, broadband, millisecond flashes, found primarily at high Galactic latitudes, with dispersion measures much larger than expec…
Erasing the Milky Way: new cleaning technique applied to GBT intensity mapping data
L. Wolz, C. Blake, F. B. Abdalla +8
We present the first application of a new foreground removal pipeline to the current leading HI intensity mapping dataset, obtained by the Green Bank Telescope (GBT). We study the…
Dispersion Distance and the Matter Distribution of the Universe in Dispersion Space
Kiyoshi Wesley Masui, Kris Sigurdson
We propose that "standard pings", brief broadband radio impulses, can be used to study the three-dimensional clustering of matter in the Universe even in the absence of redshift in…
Interpreting the unresolved intensity of cosmologically redshifted line radiation
Eric R. Switzer, Tzu-Ching Chang, Kiyoshi W. Masui +2
Intensity mapping experiments survey the spectrum of diffuse line radiation rather than detect individual objects at high signal-to-noise. Spectral maps of unresolved atomic and mo…
A GPU-based Correlator X-engine Implemented on the CHIME Pathfinder
Nolan Denman, Mandana Amiri, Kevin Bandura +17
We present the design and implementation of a custom GPU-based compute cluster that provides the correlation X-engine of the CHIME Pathfinder radio telescope. It is among the large…
A compression scheme for radio data in high performance computing
Kiyoshi Masui, Mandana Amiri, Liam Connor +11
We present a procedure for efficiently compressing astronomical radio data for high performance applications. Integrated, post-correlation data are first passed through a nearly lo…
