Mark July 4th in your calendars! That's when the 11th Open Day at our gravitational-wave detector GEO600 will take place.

ℹ️ https://www.geo600.org/openday2026

Just drop by GEO600 south of Hanover, Germany, between 12:00 and 16:00 CEST, talk to our researchers, and get insights into a cutting-edge research facility.

P.S.: Last chance to see! This Open Day will be the last as GEO600 will cease operations at the end of this year.

📣 New title picture 🖼️

The diagram shows the results from the most sensitive search for continuous gravitational waves to date.

Researchers at @mpi_grav have used the computing power donated by tens of thousands of volunteers to @einsteinathome to search for the weak and yet to be detected signals deeper than ever before in @LIGO data.

They were the first to find all hardware injections (signals artificially added to the data by moving the LIGO mirrors).

Because computing power and efficiency are key, the team expects their results to be competitive with unpublished results by LIGO researchers based on O4 data, which is not yet publicly available.

“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...

Our next LIGO Virgo KAGRA webinar will discuss tests of general relativity with #GWTC4 (papers https://arxiv.org/abs/2603.19019 https://arxiv.org/abs/2603.19020 https://arxiv.org/abs/2603.19021).

If you you are curious about understanding gravity and the nature of black holes please join!
