Initial sky localization. 90% area 1,200 sq deg.

Initial three-dimensional volume localization. Distance around 96 Mpc.

Oo! Interesting #GravitationalWave candidate #S251112cm potentially from a *subsolar* mass source

If real, the source is probably has chirp mass ~0.1–0.87 solar masses

False alarm rate 1 in 6.2 yr

@merrdiff.bsky.social !!! So great to connect with you after all these years & see that you are doing cool astronomy work too!!

Summiting Eagle Cap for 2nd time (Fall 2024)—first summit in 2015 & failed summit attempt in 2022. Best views up there & got to share it with Pris! #Hiking #backpacking #summit #EagleCap #GoProMAX

I remember her PhD work & maybe NASA. Had no idea about marriage (CONGRATULATIONS!) and law school--awesome! Recently went thru exercise of LHO operators...think I worked with Dani from around 2006-2010-ish. Please say "hi" to her for me & wish her luck on the bar!! :)

Ohhhh, Dani!! Yes, that's right--I remember she was our Laser Safety Officer way back when! Now you got me trippin' then. Maybe there was a time we did have a recorded voice! (and maybe only the Laser Safety Officer would do this). My memory could definitely be off! :)

Oh interesting. Now I'm curious about this announcement!

And I wonder if I met your wife. I've been an operator at LIGO Hanford Observatory since '98. :)

"...terminal that uses text-to-speech software to create a "verbal alarm"" that announces different states/alarms for the detector. (thought this was computer voice)

Would it be that voice perhaps? If so, I could try to record it during my eve shifts this/next week. Hope this helps! :)

Hey @asleepywanderer.bsky.social & @sevenrasmussen.com:
Ooo, what voice we are talking about? Whenever operators announce we are Laser SAFE/HAZARD, we speak over the intercom (hate hearing my voice! LOL).

However, since about 2015 (when aLIGO went online), we have used a script "run from a...

I started a #NativesinSTEM starter pack. If you want to be added, tell me a little bit about yourself, including who your people are and what you study

go.bsky.app/4hoZMPV

@taramcallister.bsky.social I'll try to figure out how to turn this into a feed too.

Oh, another friend on here mentioned me and then I think you added me. :) And thanks for explaining how Starter Packs work! :)

I'm not totally sure how a Starter Pack works, but it looks like I'm added, I clicked the Follow All button, and I introduced myself! Look forward to connectin' with ya'll! :)

I had Sharon Yellowfly (my mom!) translate the press release into Blackfoot! Oh & here's an article from Caltech from a couple days ago about my Headdress transfer in Jun2024:

Oki All! Looks like I'm added but I didn't share about myself! (I'm a total bsky newbie!)
I’m Corey Gray; member of the #SiksikaNation (Blackfoot); working at Caltech/LIGO since '98 after finishing undergrad in Physics & Applied Math.
We made news in 2016 for the historic discovery of....

Oh and I forgot—I work at the LIGO Hanford Observatory in Washington state. 🤓

Oki @asleepywanderer.bsky.social, @astroholbrook.bsky.social, @ordinarystarman.bsky.social !
I’m Blackfoot (Siksika Nation). There is also a newly formed Society Of Indigenous Physicists too!

Oki/Hello!
Excited to return to #Blackfoot lands in #Mohkinstsis/#Calgary in a few weeks & share about #LIGOVirgoKAGRA, #GravitationalWaves, #SharonYellowfly's translations of #astrophysics, & #SciComm at #CCTC2024!
