We present the results of an approximately 6,100 square degree 104--196MHz radio sky survey performed with the Murchison Widefield Array during instrument commissioning between 201…
Representations of Time Coordinates in FITS
Arnold H. Rots, Peter S. Bunclark, Mark R. Calabretta +3
In a series of three previous papers, formulation and specifics of the representation of World Coordinate Transformations in FITS data have been presented. This fourth paper deals…
Imaging an Event Horizon: Mitigation of Scattering Toward Sagittarius A*
Vincent L. Fish, Michael D. Johnson, Ru-Sen Lu +10
The image of the emission surrounding the black hole in the center of the Milky Way is predicted to exhibit the imprint of general relativistic (GR) effects, including the existenc…
Comparison of algorithms for determination of rotation measure and Faraday structure I. 1100 - 1400 MHz
X. H. Sun, L. Rudnick, Takuya Akahori +14
(abridged) We run a Faraday structure determination data challenge to benchmark the currently available algorithms including Faraday synthesis (previously called RM synthesis in th…
