What are Fast Radio Bursts?

There have always been flashes in the night sky...

...from comets...

...to supernovae

But Fast Radio Bursts are different. Why?

Their properties

We know of approximately 25 sources...

...of which 1 repeater

They're less than 0.005 seconds long...

...and from very, very far away...

...yet they're very, very bright!

So how do we detect them?

In 2007, at the Parkes observatory...

Pulsar with profile

...people were looking for pulsars...

...but found this

It was unlike anything we had ever seen before.

Duncan Lorimer

Why? Because the signal had travelled a long way...

...from beyond the Milky Way

Perytons caused complications...

...until Emily showed they happened during lunch...

...and were caused by microwaves

In 2013 another FRB was found...

...and in 2014 one at Arecibo

(That repeater? Also from Arecibo)

And after that we started seeing more and more of them.

So what do I do?

frbpoppy

I do population synthesis

There are many FRBs...

...but we don't see all of them

I make FRBs on a computer...

...and use virtual telescopes to look at them

If real telescopes see what I see...

  • Real

  • Virtual

...then I can tell you about the FRBs we don't see!

  • Real

  • Virtual

Am I alone?

No...

And with some support from...

...we work as a team on...
