A recent paper, Discrete Steps in Dispersion Measures of Fast Radio Bursts, has generated a lot of excitement. Paul Carr reviews the basic facts about the 11 known FRBs and what this strange pattern might imply.

Update: Petroff, et. al., Finding the Source of Perytons at the Parkes Radio Telescope

Further Update: Five new FRBs were recently reported.  Only one of these five (130626) has a Dispersion Measure close to a multiple of 187.5, so it could just be a fluke, but FRB 150418 was also reported, and it's DM is 776.2, which is close to 4 x 187.5.

Episode 17 - The Long Delays

Release Date: 29 October 2014

Alan Penny

Is SETA really just local SETI? It makes sense to me, and to Alan Penny, coordinator of the UK SETI Research Network. We talk to Dr. Penny about the future of SETI. Then, we talk to another Scottish astronomer Duncan Lunan about the scientific mystery of the Long Delay Echoes. Are the LDEs from a Bracewell Probe?

Music by DJ Spooky, Jason Robinson, Erika Lloyd and George Hrab
