➥ Tip! Refine or expand your search. Authors are sometimes listed as 'Smith, J. K.' instead of 'Smith, John' so it is useful to search for last names only. Note this is currently a simple phrase search.

[ascl:1906.003] FREDDA: A fast, real-time engine for de-dispersing amplitudes
Bannister, Keith; Zackay, Barak; Qiu, Hao; James, Clancy; Shannon, Ryan

FREDDA detects Fast Radio Bursts (FRBs) in power data. It is optimized for use at ASKAP, namely GHz frequencies with 10s of beams, 100s of channels and millisecond integration times. The code is written in CUDA for NVIDIA Graphics Processing Units.

[ascl:2204.008] RMNest: Bayesian approach to measuring Faraday rotation and conversion in radio signals
Lower, Marcus E.; Kumar, Pravir; Shannon, Ryan M.

RMNest directly fits the Stokes Q and U (and V) spectra of a radio signal to measure the effects of Faraday rotation (or conversion) induced by propagation through a magnetized plasma along the line of sight. The software makes use of the Bayesian Inference Library (Bilby; ascl:1901.011) as an interface to the dynesty (ascl:1809.013) nested sampling algorithm.
