No big deal, just a first look at spatially resolved star formation just after the epoch of reionisation with JWST FRESCO NIRCam Slitless Spectroscopy 😜.

Is your brain ready for a LOT of interdisciplinary exoplanet knowledge! 🧐🤯 You know it is!

🧵In Jan 2021, Keith Putirka, Siyi Xu, and I joined forces to put together 15 chapters (and a workshop!**) written by experts in their field, where the core of each chapter was:

Breaking my long silence to share results from a project I have been working on for more than a decade. Marla Geha and I were discussing how frustrating it was that there were so many comparisons of models to just ONE Milky Way. Why not 100 MWs, we thought? 🤔

Absolutely beautiful and amazing work! Sometimes one is truly lucky, I mean what are the odds that the 2nd heaviest BH in the MW (after Sgr A*) is part of a stream (ED-2 for our Emma Dodd and characterized by Eduardo Balbinot) that we were studying using spectra from ESO?! 🤩🤩

Super proud to see this paper on the arxiv today! Alberto visited my new group at ISTAustria for 3 months in the end of 2023, and this is the result of that visit! Thread:

academia has you beefing with someone 3k miles away who is also one of only 4 people on earth who likes the same stuff as you

I repeat: If you’re born with a passport that allows you to travel without anxiety @ border, frequent humiliation, worry of not seeing family for yrs, and infinite waits for visa, you have a huge privilege.

I bet everyone without this privilege has a traumatic story to tell.

Excited to present our recent work, led by Chamilla Terp in her very first, first-author paper based on her Bachelor-thesis project, on the much debated JADES spectrum of the source GS9244 🙌

Cambridge, MA saw an ~85% decrease in “incapacitating” injuries and a ~92% decrease in serious “non-incapacitating” injuries for people on bikes while ridership increased, after it started installing a connected network of protected bike lanes.

SF should follow Cambridge’s lead.

Very excited to have been involved in this paper led by Anna de Graaff that hit the arxiv today, where we present the new record holder the most distant massive quiescent galaxy to be spectroscopically confirmed (for now):

Eclipse chasing, New England edition #skitheeast

So many of you are getting a taste of being an astronomer today! We travel to the ends of the Earth for a glimpse of something sublime -- the tops of dormant volcanos, the dry hearts of deserts, even Antarctica -- only to be thwarted by goddamn clouds!

🌓🌎🌞 <-- lunar eclipse

🌎🌓🌞 <-- solar eclipse

🌎🌞🌗 <-- apocalypse

1 of reasons we have to keep hammering this is because looking at the sun only KINDA hurts, i.e. its bearable. But at this time your lens is focusing solar light into a doombeam that 100% can/will damage your vision for the rest of your life. Don't do it. youtu.be/Tzy1iMhlx5Y?si…

me:

An exemplary effort from the exoplanet community to rally together and identify the key areas #jwst must invest Director's Discretionary Time in. Extragalactic science, the other key focus area for the telescope, would benefit from a similar program.
