Milestone Alert! 🚨 The core of the Roman Space Telescope has completed thermal vacuum testing which mimics space conditions.
This is one of the final tests before the observatory is completely integrated!

NASA's SPHEREx mission, which launched earlier this month, will use software from the Arizona Cosmology Lab to answer questions about the first moments after the Big Bang. Read more: https://t.co/0OecqY9m2u

[国立天文台 すばる望遠鏡 @SubaruTelescope]

#すばる望遠鏡 に、特殊な「複眼」が新たに装備されました。約2400個に及ぶ「目」で多数の天体からやって来た光を同時に捉え、色に分けて観測します。宇宙の成り立ちと銀河の生い立ちを精密に理解するために不可欠なこの観測装置 #PFS が、いよいよ本格始動します！

Major Milestone Alert🚨
Roman's Wide Field Instrument has been installed into the Instrument Carrier, completing the Instrument Payload Assembly (IPA)!

The IPA also includes the Coronagraph Instrument and the Optical Telescope Assembly.

The final puzzle piece is here!

After passing final thermal vacuum testing at @L3HarrisTech, the Nancy Grace Roman Space Telescope's Optical Telescope Assembly has arrived at @NASAGoddard.

Milestone alert 🚨 The Roman mission is moving towards the next stage of construction, bringing all the components together!

Take a look at how we got there ⬇️

[Arizona Cosmology Lab @azcosmolab]

We present the first cluster lensing measurement using the kinematic lensing technique. Estimating shear from three source galaxies, we find results broadly consistent with weak lensing. Our typical shear uncertainty is 0.026, a ~10x improvement over the weak lensing shape noise.

Today I am delighted to share a paper about a new way to measure the cosmic web🕸️

For astronomers, I'll unravel it here with a short thread... /n

[Yu-Hsiu Huang @astrohsiu]

This is an inspiring documentary that I recommend everyone to watch!

Aurora Borealis captured in Saguaro NP West, near Tucson AZ. @whatsuptucson hope more people can enjoy the show!

I will post some time lapse after some sleep.

[Simons Foundation @SimonsFdn]

It is with great sadness that the Simons Foundation announces the death of its co-founder and chair emeritus, James Harris Simons. Jim was an award-winning mathematician, a legendary investor and a generous philanthropist. https://t.co/w48DhauUVj

[Minh Nguyen @MinhNguyenAstro]

I should really wait till Monday but I can't! On Monday we'll present a brand new collab: The Beyond-2pt Collaboration. It has been a humbling experience to learn so much in this challenge over the last 2 years. A Cosmology Talks with @just_shaun will follow up the paper shortly!

[Natasha Latouf🍉 @nertushka]

Hi yall! I am developing an open resource for applying to post-docs as I go through the process. Please drop any fellowships or positions that are open every year in the comments, and I'll add them to this public spreadsheet! Field specific also welcome :)

[Arizona Cosmology Lab @azcosmolab]

The Arizona Lensing Day started in 2022 as an informal event that brings together students, PDs, faculty from UA and ASU for 8 hours of fun, science, and conversations on lensing/cosmology topics. Yesterday’s highlights: research talks, panel discussions, and group interactions.

[Nancy Grace Roman Space Telescope @NASARoman]

Roman's "eyes" have passed their vision test!

The Imaging Optics Assembly, IOA, consists of 10 mirrors that must be aligned perfectly to direct light to the science instruments to obtain the most precise images.

Next steps: environmental testing! https://t.co/5YrR4AnkfP

@ClaireLamman Are the BAO peak on the side for different redshift?
