“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...

Arts and Science Residency – Call for proposals

The Department of Astrophysical and Cosmological Relativity at @mpi_grav Potsdam has teamed up with the Center of Gravity at the Niels Bohr Institute in Copenhagen.

The two institutions are offering a joint arts and science residency program, with residencies available at each site for up to three months.

New leadership team to guide the Einstein Telescope Collaboration – Change at a defining moment for gravitational-wave science

The international Einstein Telescope (ET) Collaboration announces a change in its scientific leadership, as a new spokesperson team takes office on 23 March 2026. Michele Maggiore and Angélique Lartaux will serve jointly as spokesperson and deputy spokesperson.

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!)

From Erlangen with Love

Members of the “Binary Merger Observations and Numerical Relativity” research group in the “Precision Interferometry and Fundamental Interactions” department at @mpi_grav in Hanover are on a physics — and by no means secret – mission at the spring meeting of the Matter and Cosmos Section (SMuK) of the @DPGPhysik at the @FAU.

There, they present their research results and discuss the current state of astronomy with gravitational waves with their colleagues.

The GEO600 project will end on 31 December 2026

The gravitational-wave detector GEO600 south of Hanover, Germany, will cease operation at the end of 2026. The last Open Day will take place this summer. Group tours will be offered until the end of the year. In early 2027, dismantling of the facility will begin.

@maxplanckgesellschaft director Karsten Danzmann will retire on 31 March 2026. As a consequence, funding for the GEO600 project will terminate at the end of the year.

GEO600 is a beacon of international research. Technologies developed and tested in the GEO project are now used in all major gravitational-wave detectors around the world. The findings and experience gained also play a role in preparing future observatories such as the Einstein Telescope and the Cosmic Explorer.
