Dr. Catherine A. Clark Dr Jake Taylor If current rates of recession continues, the last total eclipse is in ~380 million years! Please see my silly April fools day papers with very serious calculations! arxiv.org/abs/2403.20175

I just submitted a new paper! And this one heads back out to high redshift with a closer look at some very deep spectra of two of the absolute most distant galaxies currently confirmed: JADES-GS-z11-0 and JADES-GS-z13-0. Here's a thread! arxiv.org/abs/2404.04325

Gaia spots Milky Way's most massive black hole of stellar origin! It's 33 solar masses, dormant, 2nd closest to Earth at ~2000 light years away, part of a wide binary with an old giant star, with estimated age of 11 Gyr: youtu.be/cU00B-6DeSQ #GaiaBH3 cosmos.esa.int/web/gaia/iow_2…

Paper day: arxiv.org/abs/2404.11604 We show that Gaia BH3 is part of the ED-2 star cluster. The update astrometry puts GaiaBH3 in excellent agreement with the orbit of ED-2. Using some ESO data we got last period we also show that ED-2 is very likely a disrupted globular cluster

Are you interested in dwarf galaxies, star clusters, and/or streams? We are hosting a workshop on the topic July 8-11 at UChicago/KICP! Abstracts/registration due April 30. kicp-workshops.uchicago.edu/2024-DGSCS/ind…

Most intriguingly, the discovery suggests that BH companions are (much!) more common around metal-poor stars: only 1 in 10,000 nearby stars are as metal-poor as Gaia BH3! We will be concentrating some of our BH search efforts on metal-poor halo stars. 4/n

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? 🤔 sagasurvey.org

Rubin Observatory's 8.4-meter mirror is finally, well, a mirror! 🥳 The glass got its shiny coating this past weekend—but what did that actually look like? Find out in the fifth and final video in our "Making of Rubin's 8.4-meter Mirror" series ✨ #CaptureTheCosmos

The world’s most powerful space telescope has done it again. Webb has discovered what appears to be a new record-holder for the most distant known galaxy — shattering its own previous record. This galaxy existed only 290 million years after the big bang: blogs.nasa.gov/webb/2024/05/3…

William Keel Bill, I'm still trying to wrap my head around it too. It's so bright, it appears in my paper from last year as a "visually rejected candidate" because of how bright and extended it was. Heck, it's *right next to* a galaxy with a Balmer break almost coincident:

This is too real :(

Paper day! No machine learning this time, just good old astrophysics. The metallicity distribution function is one of the most commonly measured properties, as it's often the most attainable for some of the smallest dwarf systems. However, there's been a lack of theory to
