Should’ve posted yesterday! In a paper titled “Searching Within Galaxies for the Earliest Signs of Quenching With Spatially Resolved Star Formation Histories in UVCANDELS” we divided star-forming galaxies into bits to see how star formation changed depending on location over the last billion years.

🔭 The reason I rarely ask questions at conferences is that there’s always the risk of me referring to galaxies with particularly stochastic star formation as “burst-y quench-y bois” 🤦🏼

Good time to remind people that when you call your reps that suck you can remind the staffers that they can and should quit.

1. Major exclusive breaking news: Marco Rubio may have just banned trans foreigners seeking visas with correct gender markers from US Entry. A new cable, effective immediately, says visas must contain assigned sex at birth and should be rejected if they don't. Subscribe to support our journalism.

This is how you do it. Thank you, @tupelopress.bsky.social!!!
The NEA has released their updated literature grant guidelines. They are appalling.
Tupelo Press will not be altering our 25-year mission to promote contemporary poetry and literary prose by emerging and established writers of diverse ethnic and cultural backgrounds, including, especially, women and writers of color, as well as the LGBTQ+, immigrant, and Native American communities. We aim to develop wider audiences for, and deeper understanding of, innovative, multi-cultural writing by essential participants in this conversation. At the same time, we undertake to enhance the reading experience itself by publishing and distributing gorgeously designed and produced books.
If adherence to our principles means that we will be ineligible for NEA grants going forward, so be it.
Compliance with the new regulations would be immoral.

Pretty depressing to think that all it took was three weeks for astronomers to go from excitedly showcasing their work at AAS to the blind panic and fear experienced when their funding gets shut off because they called their students diverse on an NSF. Push back. We’re in this together.

Made it to National Harbor for the American Astronomical Society's #AAS245 meeting! I'll be posting a lot this week and will try my best to summarize all of the talks I attend. If you want to follow along, great! If that sounds annoying mute me or #AAS245.
