David Weinberg and I tackle a key question in Galactic Archaeology -- "how many elements matter? "-- i.e., should we measure elemental abundances if the measurement uncertainties are similar (or larger) than the intrinsic variance. (the answer is yes). arxiv.org/abs/2102.04992

Highly recommend!

Finding odd data points 🌟

The EHT will be announcing groundbreaking results Thursday May 12th, 13:00 UT. Tune in to one of our live streams! Choose a stream here: eventhorizontelescope.org/blog/event-hor… #EventHorizonTelescope

My hypes are up, although it turns out the announcement is about the image itself. But still, wow!

PAPER TIME The Ages of Galactic Bulge Stars with Realistic Uncertainties (ApJ, subm) Featuring the first ever public use of The Mixing Length Isochrones of Terror Figure (TM) that I've been teasing in talks for 2 years. Check it out! arxiv.org/abs/2205.07964

Beautiful (and trivial) #GaiaDR3 result. The Mass-Radius relation of isolated M-dwarfs. 10-15% inflation over Baraffe et al (2015) at all masses, and only 1-2% scatter around the mean! Magnificent!

What up twitter! The majority of early publications resulting from the KITP program "Probes of Transport in Stars" had male-only author lists arxiv.org/abs/2206.10617

Check it out! The latest Astropy paper is on ArXiv today: arxiv.org/abs/2206.14220 Of note: 1. I'm a co-author this time (+ >100 other excellent folks; ref: github.com/astropy/astrop…) 2. it was written using Rodrigo Luger's #showyourwork so here's the source: github.com/astropy/astrop…

"You need at least two exponentials to get physics" Rich Townsend reminding us that physical prescriptions and physics are different things. Also, convection is an advective, not diffusive, process #tasc6

Yaguang Li Some clump stars should have interacted. Construct mass proxy, see zero age He burning edge. Look at outliers, some data issues, few real under-luminous. Some very low mass-binary, started massive? Others massive. Not metallicity, error bars, scaling relations. #tasc6

I need this🥲

Saw this on Chinese social media today. "Grant me the serenity to accept the things I cannot change, The courage to change the things I can, And the wisdom to know the difference." This kind of serenity is so difficult to achieve in today's environment...

We are happy to announce our new paper in Nature!  We have found a crucial piece of direct evidence of how the IMF varies with its environment through LAMOST and Gaia.

Excited to announce our Deep Learning Tuning Playbook, a writeup of tips & tricks we employ when designing DL experiments. We use these techniques to deploy numerous large-scale model improvements and hope formalizing them helps the community do the same! github.com/google-researc…

Understanding Deep Learning A great textbook that covers foundations of deep learning, techniques for training neural networks, and modern neural network architectures(CNNs, Transformers, GNNs, GANs, diffusion models, deep RL, etc). Get your copy(WIP): udlbook.github.io/udlbook/

USyd colleagues: I was an academic rep on the NTEU bargaining team for 18 months. Now that I also have a little distance, I’d like to share some honest thoughts about what has gone wrong this round (very long thread)
