Atacama Cosmology Telescope

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!

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.

What a beautiful picture of the infant Universe! Congratulations to @act-pol.bsky.social! Papers available from act.princeton.edu.

You can watch yesterday's Atacama Cosmology Telescope @act-pol.bsky.social webinar on our new DR6 results here! (NB this was aimed for scientists; we also look forward to sharing more about our early-universe images) www.youtube.com/watch?v=sETY...

The @act-pol.bsky.social DR6 dataset is now included in the Aladin Sky Atlas, how cool is that! #astrosci

Atacama Cosmology Telescope Publishes Final Major Data Release Atacama Cosmology Telescope Publishes Final Major Data Release on Simons Foundation

The @act-pol.bsky.social team is publishing its final major data release, providing an even clearer view of what the universe was like 13 billion years ago: www.simonsfoundation.org/2025/03/18/a... #science #astronomy

It was a privilege to hear Princeton University's Prof. David Spergel, also President of the Simons Foundation, presenting the latest data from the @act-pol.bsky.social Atacama #Cosmology Telescope at EPFL. #astronomy www.simonsfoundation.org/2025/03/18/a...

Backlighting extended gas halos around luminous red galaxies: kinematic Sunyaev-Zel'dovich effect from DESI Y1 x ACT The gas density profile around galaxies, shaped by feedback and affecting the galaxy lensing signal, is imprinted on the cosmic microwave background (CMB) by the kinematic Sunyaev-Zel'dovich effect (k...

Come and check our most recent paper on measuring the kinematic Sunyaev-Zel'dovich effect using @desisurvey.bsky.social luminous red galaxies and the latest dataset from @act-pol.bsky.social 😍
