Sandro Tacchella

Let's do some old school live skeeting of Sandro Tacchella's talk on early galaxies and JWST at #NAM2025, shall we? (1/n)

This result is inconsistent with just about every observed stellar-mass black hole we know (as I and several others have pointed out in the published literature) and is even inconsistent with observed masses of the LIGO black holes (as identified by the authors themselves!).

Last two lectures of term done... and on the way to Paris for some science on early galaxy formation!

Post a picture you took (no description) to bring some zen to the timeline

Figured I would get in on this whole starter pack thing and list (in whatever order bsky chooses) scientists working on studying galaxies (broadly defined, including galaxy formation/evolution + near-field cosmology). If I missed you and you'd like to be added, let me know!

Poster for the Lamat summer program at UC Santa Cruz for undergraduates, particularly community college students, to gain research experience in astrophysics. Apply at lamat.science.ucsc.edu

Reminder that the UCSC Lamat Institute application deadline is early this year, December 1! Lamat is an outstanding program that offers research opportunities and professional development for undergrads, particularly community college students.

On the way to work...

My first Gresham college lecture on galaxies is out. Spoiler alert: space is big. www.youtube.com/watch?v=31mK... 🛰️ 🧪

Since it's already fall(!), wanted to share the site where I've been compiling open source astro teaching materials -- e.g., textbooks, lecture notes, visualizations: astroteaching.github.io

Pretty piecemeal to now, but would love to link to any other resources not already included here :)

Comparison of CFD methods

Interested in how different methods for computational fluid dynamics compare? I'm sharing some intro Python scripts on solving the isothermal compressible Euler equations with Finite Volume, Spectral, Lattice-Boltzmann, and SPH methods here: github.com/pmocz/cfd-co...

Drawings of a number of star clusters and nebulae made by james Dunlop

A series of seven Astro photos showing three galaxies, and four star clusters

From about April - June in 1826, James Dunlop discovered and catalogued many southern hemisphere deep sky objects from his Parramatta observatory, located about 30 mins from where I live.

So one night during lockdown, I followed his list and photographed the same objects from home.

Visiting Seoul National University (SNU) this week. Great pleasure to meet and discuss science with friends and collaborators!

Ok, getting started with this!
