Lovely op-ed by @astrokatie.com featuring our recent @nanograv.bsky.social results!
I wrote about being tossed about on cosmic gravitational waves, for @washingtonpost.com: https://www.washingtonpost.com/opinions/2023/07/06/gravitational-waves-new-view-universe/
Opinion | I’m a physicist. Last week’s gravitational waves announcement sent me reeling.
Hum from gravitational waves gives a completely new and audacious view of the universe.

It’s been a long time coming!
🧪 Some lovely plots for the history books: the Hellings-Downs curve, predicted in 1983, and finally observed by NANOGrav! Their detection paper is up now: arxiv.org/abs/2306.16213

News from pulsar timing arrays is hitting the big time! https://www.washingtonpost.com/science/2023/06/28/gravitational-wave-background-nanograv/
In a major discovery, scientists say space-time churns like a choppy sea
The claim of a gravitational wave background suggests the universe is constantly roiled by violent events that happened over the past 13 billion years.

On June 29th, we in the North American Nanohertz Observatory for Gravitational waves (NANOGrav) are announcing our results. The culmination of 15 years' work! The Australian (Parkes), European + Indian, and Chinese Pulsar Timing Arrays are also releasing their independent results on the same day.
