Herzlichen Glückwunsch zum Geburtstag, GW170817! Wir denken gerne an den Tag zurück, an dem wir Dich entdeckt haben. Forschende am @mpi_grav und der @unihannover haben eine zentrale Rolle bei deiner Entdeckung gespielt.

Wer noch einmal die Spannung der Entdeckung durchleben möchte, kann dies mit unserer Pressemitteilung aus dem Oktober 2017 tun: https://www.aei.mpg.de/368858/first-observation-of-gravitational-waves-from-merging-neutron-stars.

Das alles ereignete sich weniger als zwei Wochen nachdem der Nobelpreis für Weiss, Barish und Thorn bekannt gegeben wurde.

Happy birthday, GW170817! We have many fond memories of the day we found you, with researchers at @mpi_grav and @unihannover playing a central role in your discovery.

Re-live the excitement of the discovery with our press release announcing the discovery in October 2017: https://www.aei.mpg.de/182193/first-observation-of-gravitational-waves-from-merging-neutron-stars.

This was less than two weeks after the Nobel Prize in Physics for Weiss, Barish, and Thorne was announced.

Le 17 août 2017 occupe une place spéciale dans la mémoire des astrophysiciens. En cette journée, les caractéristiques d'un événement d'ondes gravitationnelles (GW170817) suggèrent la première détection d'une fusion d'étoiles à neutrons. Un branle-bas de combat digne des meilleurs films d'action allait ensuite animer 70 équipes d'astrophysiciens pendant deux mois!

"Quasiuniversal" just got quantum gaslit—scalar-tensor gravity rips the mask off GR waveform assumptions. Gravity isn’t broken. It’s just multilingual. 🧬🕳️ #GW170817 #DEFTheory #GlitchTheSky

It has been, somewhat unbelievably, just over seven years since we detected #GW170817, which was notable for just how many firsts it represented in astronomy:
+ First observed merger of two neutron stars
+ First observation of #GravitationalWaves and light from the same event
+ First confirmed kilonova from a neutron star collision.
You'll find lots of coverage in the fediverse from @LIGO, but I'll leave you with this infographic I made, and my colleague translated into Glasgow dialect...

Start your week with all the key facts about #GW170817 with this infographic by @UofGravity's @daniel_williams

#GW170817 is the #GravitationalWave with the closest source. It is one of our loudest detections

Binary neutron stars are lower mass than black hole binaries, so their chirps are much longer

#GW170817's source was identified as in galaxy NGC 4993. It was observed using telescopes for all parts of the electromagnetic spectrum, making it one of the most studied astronomical events ever! It's afterglow was still visible years after the merger

#Astrodon

Combining data from LIGO Livingston, LIGO Hanford and Virgo, we localized #GW170817's source on the sky. Having 3 detectors is crucial for this

Using this localization, teams of astronomers from around the world were able to successfully hunt for GW170817's kilonova

Happy birthday to #GW170817 our first binary neutron star detection, and the first #GravitationalWave with electromagnetic counterparts!

The gamma-ray burst following the merger was spotted by the Fermi and Integral telescopes and later many other telescopes

Today marks the anniversary of #GW170817, our first observation of a binary neutron star, and our first multimessenger source!

Happy Birthday, GW170817! Six years ago today, @LIGO and Virgo observed gravitational waves from merging neutron stars for the first time, and many other telescopes observed the electromagnetic radiation produced by the event.

Happy Birthday, GW170817! Heute vor sechs Jahren beobachteten @LIGO und Virgo erstmals Gravitationswellen von verschmelzenden Neutronensternen und viele andere Teleskope die vom Ereignis erzeugte elektromagnetische Strahlung.
