Die Sendung „Forschung aktuell“ im Deutschlandfunk hat am Freitag auch über 10 Jahre Astronomie mit Gravitationswellen berichtet.

Für den Beitrag „Ein sensationelles Beben durch Raum und Zeit“ sprach Frank Grotelüschen mit Forschenden am @mpi_grav in Potsdam und Hannover. Es geht um die erste Entdeckung, die wichtigsten Erkenntnisse des vergangenen Jahrzehnts und die Zukunft mit neuen Detektoren wie dem Einstein-Teleskop und LISA.

“We are delighted that the European Space Agency has now chosen the industrial partner who will take on the manufacturing of LISA, marking another major step towards launch”, says Dr. Jonathan Gair, chair of the LISA Consortium council and group leader at @mpi_grav in Potsdam.

🚀 LISA, GRACE und NGGM neuem Podcast 🎧

In der ersten Folge des ganz neuen Podcasts „Chip Happens“ geht es auch um die Satellitenmissionen @LISA, GRACE und NGGM, die Gravitationswellen beobachten sollen bzw. jetzt schon Klima-Indikatoren global überwachen.

Gerhard Heinzel vom @mpi_grav bringt euch (etwa ab der Mitte des Podcasts) auf den neuesten Stand.

#LISACommunityTalks

The #LISACommunity recently hosted a talk by Senwen Deng on a paper by Senwen Deng, Stanislav Babak, Maude Le Jeune, Sylvain Marsat, Éric Plagnol, Andrea Sartirana: "Modular global-fit pipeline for LISA data analysis", linked here 👉 https://arxiv.org/abs/2501.10277

Here's a summary of the paper:

"The #LISAMission data band is expected to be dominated by gravitational wave signals emitted by a plethora of astrophysical sources. Signals of the Galactic white dwarf Binaries are long-lived, overlapping in time and their unresolved residual forms a confusion noise. Massive Black Hole Binary signals are loud and broadband, hindering the estimation of the noise property, the knowledge of which is key to the detection and parameter estimation for the gravitational wave signals. We came up with a modular two-stage iterative pipeline prototype to disentangle the intertwined signals and to infer the parameters for the different signal sources and the noise level. We demonstrated its capability by applying it to simulated LISA dataset known as "Sangria", where we managed to recover the injected parameters at the simulation with faithfulness."

The new @LIGO Magazine is out and available online!

This time…

… with an article by Elise Sänger, PhD student at @mpi_grav in Potsdam, on the formation of the LIGO-Virgo-KAGRA Climate & Sustainability Committee (page 16)

… @harte_echtzeit, a scientist during the day and a musician during nights, on his gravitational-wave inspired music which he also presented during our 2024 Open Day at GEO600 (page 20)

… an update from @LISA on the full-scale telescope prototype revealed by NASA (page 24)

… and a lot more great reading from the science community.

New @DAAD_worldwide “science in a nutshell” video about @LISA!

Got four minutes to spare? Why not use them to listen to Marie-Sophie Hartig explain how @LISA will observe the gravitational-wave Universe?
