“A Search for a Supermassive Black Hole Binary” – recent AAS Nova article about a paper by Jacob Cardinal Tremblay et al.

Jacob is a PhD student at @mpi_grav Hannover in the “Pulsar Timing Arrays” research group of the “Observational Relativity and Cosmology” department.

After giving a talk at APS last week, I gave a talk to my old group at Glasgow uni today about the work we've been doing on site evaluation for Cosmic Explorer.

Very nostalgic to give a talk in KB 312 and revisit the view that distracted me during so many undergrad astronomy lectures!

I'm 10+ years wiser now but I gotta admit, it's still a little bit distracting...

With the news being out that GEO600 will cease operations at the end of the year, if anyone who is/was involved with it wants a high res copy of my travel poster to print don't hesitate to get in touch!
(I also have a version with the infamous tractor!)
