Hi! I'm a neutrino! Let me introduce myself.
YouTube video by Eve Vavagiakis Hi! I'm a neutrino! Let me introduce myself.

Excited to publish this #NSFFunded animated video project introducing neutrinos as imagined by the illustrator of “I’m a Neutrino”!

A 60 second intro to the neutrino particle, the video features the Atacama Cosmology Telescope @act-pol.bsky.social!

Atacama Cosmology Telescope

Looking forward to sharing our new results from the Atacama Cosmology Telescope @act-pol.bsky.social tomorrow! - this is our final big 'DR6' data release and cosmology. We'll post papers on act.princeton.edu for 12-ET and then on arxiv.

The CMB power spectra as observed by ACT, showing significantly smaller error bars than previous Planck results and extending to much higher multipoles.
