!!!New Paper out on arxiv today!!!
We measure structure formation from the cross-correlation of CMB lensing and galaxy surveys, using the new @ACT_Pol DR6 lensing map and galaxies from unWISE.

📡Proud to be part of @Penn who will extend the @SimonsObs scope to investigate the early Universe with the #AdvancedSimonsObservatory‼️
☀️Excited to lead work on this project to deploy a new renewable energy system that will make ASO a leader in green astronomy infrastructure‼️

We (@ACT_Pol) have a groundbreaking new image revealing the most detailed map of dark matter distributed across a quarter of the entire sky - drawn by CMB lensing and with implications for the growth of cosmic structures

I'll be presenting on our SZ results with @ACT_Pol today at #AAS238, in Session 211 starting at 12pm ET. arxiv.org/abs/2101.08373

Congrats to @ACT_Pol colleague Dr. Jason Stevens! 🥳
Congratulations Dr. Jason Stevens on successfully defending his PhD thesis titled "Measuring the Cosmic Microwave Background Radiation from Chile" today!!! @CornellPhysics

This enormous galaxy cluster @ACT_Pol discovered as a bright Sunyaev-Zeldovich signal has a mass of over 2 quadrillion suns and is known as El Gordo, or “the fat one,” which has always made me happy

The final Advanced ACTPol upgrade is underway! Today we extracted the almost 1 ton receiver from the telescope to install our new detector array, and enable new measurements of the oldest light in the Universe. #NSFfunded @ACT_Pol @CornellPhysics

Want to hear about our recent @SimonsObs collaboration meeting last week at #UPenn? Now you can whyy.org/episodes/signs-of-i… We had a great time on @whyy, thanks to @CoolAstronomer and @DaveHellerHW

To explain to our @DunlapInstitute colleagues the difference between different #CMB telescopes (and how cool our research is), Matt Young does and @ACT_Pol vs @SPTelescope show down

What are you doing on Thursday night? If you're an ACT grad student at Princeton you're probably putting an array and filters into the DR!

Had a great time with @TheseVibes at @wprb this morning talking about cosmology! Look out for her show Tuesday night

Dunkley: CMB lensing limits curvature to 2% and neutrino mass sum to < 0.7 eV. CMB S4+DESI will allow us to detect 0.06 eV mass! #CMBat50

Dunkley: Lots of observations of polarisation ongoing from the ground: @CMB3K, @ACT_Pol, @SPTelescope, CLASS, @BICEPTWO, ABS #CMBat50
