I’m part of the new @LIGO magazine. Starting on page 20, I write about my creative and thought process when turning #scientificdata into #experimentalmusic.

We have reached 200 #GravitationalWave candidates in O4!

The fourth observing run (O4) of our detector network has had the best performance so far, with more candidates than ever before! We are currently busy analysing all these wonderful data and look forward to sharing results

I am getting really excited for the GR Amaldi meeting in July. Lots of plans are coming together

Abstract submission deadline is Friday 21 March

Registration is open. We will have a free Early Career Workshop before the main meeting, but places are limited

https://iop.eventsair.com/gr24-amaldi16/

We will have public talks, a reception at the Glasgow Science Centre, and a science ceilidh at the conference dinner! Stay tuned for details on a sci/art exhibit

Exciting #GravitationalWave results from MeerKAT

Reassuringly, like other pulsar timing arrays, they are seeing evidence for a signal (still at evidence for level, not at detection level)

Interesting, their amplitude seems larger than others. Is the signal growing?

Inspired by #xkcd (and prompted by @CosmicRami), the types of #GravitationalWave papers.

Tag yourself, I'm no. 2

When the intro starts "We have opened a new window" you know you can skip a couple of paragraphs
