About this episode

The episode explores time-domain astronomy through the Fourier transform, discussing blazars and brown dwarfs.

In this episode, Shashank, Cole and Cormac take a look at the periodic side of time-domain astronomy through the famed, fabled Fourier transform. Cole entreats us to the time lags in blazars and Cormac gives us a weather update on a brown dwarf. Along the way, we discuss some of the instruments, challenges and patterns in periodicity.
