Are chirped gravitational wave events generally first identified by searching through libraries of chirps?
Comments below What does "GPU-accelerated butterfly matched filtering over dense bank of time-symmetric chirp-like templates" mean? (GW170817) suggest that for this technique a library of ...

In what ways are neural net classifiers "better" than search algorithms for eclipsing star system searches? (1D time series, not images of cats)
Neural net classifiers are both "hot" and useful.
TIC 168789840: A Sextuply-Eclipsing Sextuple Star System is quite an interesting read, and describes the use of one trained on a ...

Do ASKAP and ALMA have "fast dump" interferometric modes? Can they see and perhaps report Fast Radio Bursts in real time?
Chatterjee et al 2017 The direct localization of a fast radio burst and its host nicely shows a VLA detection of a repeating FRB in 5 millisecond steps nicely demonstrating the dispersion slope ...

Which data should I use to take the fast Fourier transform (FFT) to find time period for eclipsing binaries?
I am trying to use Kepler Data for Eclipsing Binaries to estimate time period, and then other parameters such as mass, eccentricity, semi-major axis, distance, etc. of the system. I want to write code ...
