After 15 years of carefully observing stars called pulsars throughout our galaxy, the @NANOGrav collaboration has “heard” the perpetual chorus of gravitational waves rippling through our universe. Much of this #gravitationalwave background is probably caused by pairs of supermassive black holes as they spiral toward collision. Most of the gigantean GW are probably produced by pairs of SBHs spiraling toward cataclysmic collisions throughout the cosmos. #news #science

Exciting news released by our colleagues NANOGrav, the European Pulsar Timing Array, the Indian Pulsar Timing Array, the Parkes Pulsar Timing Array, and the Chinese Pulsar Timing Array today. Congratulations on opening up the nanohertz frequency band of #GravitationalWave astronomy!!

This year's Gravitational Wave Open Data Workshop is on 15 to 17 May

Any theoretical physicist here with waaay to much time at hand, eager to go over the 150 pages (!) long paper https://www.researchgate.net/publication/366030351_978-620-4-73547-4 claiming that the #GravitationalWave detectors don't actually detect gravitational waves - because they cannot in the first place - but "magnetic field gradients from very fast rotating astronomical bodies" instead? For something 'from the fringe' of science this is actually pretty elaborate ...

The international #GravitationalWave detector network is expanding! The Nidian governement has approved the #LIGOIndia project https://www.caltech.edu/about/news/india-approves-construction-of-its-own-ligo

#Introduction I'm a scientist with a background in #gravity #theory #physics and #astronomy whose interests have drifted in the direction of #statistics. I'm a Professor of Statisitcs at #RIT and a member of the #LIGO scientific collaboration (currently co-chair of the #ContinuousWaves group). I analyze #GravitationalWave #data to look for signals from rapidly rotating #NeutronStars, especially #ScoX1. I enjoy #Python #Jupyter and #Debian. I also like applying #StatisticalInference to #hockey.

Did anyone spot the #GravitationalWave #NobelPrize themed question on ITVChase? Mark Labbett got the correct answer, did you? @LIGO https://twitter.com/ITVChase

#Blackhole 'carnivals' may produce the #signals seen by #gravitationalwave #detectors

@alstev
Not sure if this helps, but I still think GW150914 and GW151012 are good bass drums when played backwards!

A big bird guarding a big nest at Mid-Y station of @LIGOWA. Did you know that thirsty ravens used to make then-mystery noise in our #gravitationalwave detector by pecking ice forming around liquid nitrogen vent? Scientists at @LIGO found about that in 2017, and..
