We’ve just learned that the whole universe is humming around us. Now what?
astrophysicist Adam Frank, 29 Jun 2023

"… an impossibly vast symphony of #causeandeffect. The endless comings & goings of #galaxies, #stars & #planets create a melding of songs that you are part of too. The #NANOGrav discovery exposes the intricacy and gracefulness of that melding …"

Unabhängig voneinander: Forschungsprojekte finden Gravitationswellen-Hintergrund

Dank der hochpräzisen Signale von Pulsaren haben mehrere Projekte den Gravitationswellen-Hintergrund nachgewiesen. Der öffnet einen neuen Blick aufs Universum.

@heiseonline Das war die andere Nachricht. Nicht weniger beeindruckend:

"#Astrophysicists in the #NanoGrav collaboration have found evidence for HUGE #gravitationalwaves that could be due to merging supermassive #blackholes. This was all possible due to pulsar timing arrays which triangulate the positions of pulsars across our galaxy to work out of the distances between them change due to a passing light year long #gravitationalwave!"

- Dr. Becky Smethurst, #astrophysicist at the University of Oxford (Christ Church).

"Gorgeous, this"

yoda would surely agree.

Nice to see the Arecibo telescope in Puerto Rico being used to help the NANOGrav research into pulsars and gravitational waves! https://nanograv.org/news/2023Announcement #nanograv #space

Party for the #nanograv results! https://soundcloud.com/jobig/vangelis-pulstar-soulwax-edit

Gravity Waves Rock The Galaxy

Scientists report evidence that the whole universe around us is awash in the quiet background vibration of gravitational waves.

just incredible news from the folks at #nanograv who announced that their galaxy-sized detector has revealed the long-theorized background hum of gravitational waves resulting from the likely mergers of supermassive black holes. can't wait to see the #pbsspacetime take on it.

Thread🧵by cosmologist Katie Mack about #NanoGrav news and how pulsar timing array observations can be filtered to find effects of low-frequency #GravitationalWaves. (As opposed to LIGO which measures high-frequency GW.)
[please excuse the bird-site thread link. I can edit the link if @AstroKatie cross-posts the thread via her Mastodon acct. hint hint... 😏 ]

So cool to see that #NANOGrav has detected a gravitational-wave background! I first wrote about pulsar timing arrays 16 years ago.

The universe "hums" with gravitational waves that lie far outside the range of human experience. Their frequency is measured in decades; their wavelength is measured in light years.
The sound of the universe is approximately 37 octaves below middle C -- if you could hear it.

Scientists find evidence of a gravitational wave ‘hum’
Astrophysicists have found the best evidence yet for a low-frequency “hum” of gravitational waves rippling through the cosmos, based on 15 years’ worth of ultra-precise measurements checking the timing of radio pulses from distant stars.

Scientists are starting to sense a kind of gravitational wave they've been spent 15 years searching for--and it's really big. The rumbling waves could be created by supermassive black holes, ones that can be billions of times more massive than our sun and that lurk in the centers of galaxies.

"Big Gravitational Wave Announcement Is Coming Thursday" by @ScienceAlert - Coordinated science research announcement scheduled 1pm EDT Thursday, June 29. https://www.sciencealert.com/a-big-gravitational-wave-announcement-is-coming-thursday-heres-why-were-excited #nanograv #gravitationalwaves #astronomy

Well, since we are bracing for the impact of an imminent major announcement on pulsars and, maybe, some gravitational wave background, why not enjoy this 2004 special Science Magazine issue on pulsars!

https://science.org/toc/science/304/5670
see in particular the paper by Ingrid Stairs p.547

Will a project "using #pulsars to search for low-frequency #GravitationalWaves" report a significant detection next week? Says https://nitter.net/NANOGrav/status/1671655089478443012: "Mark your calendars and get ready for a major announcement from the #NANOGrav collaboration on June 29th!" And - coincidence? - a big primer about Pulsar Timing Arrays such as NANOGrav appeared only days ago at https://www.spaceaustralia.com/feature/humanitys-galactic-scale-detectors-pulsar-timing-arrays
