Happy to share my latest paper, characterizing a rare-to-catch post collision galaxy with nine rings! Nice write up from stsci hubblesite.org/contents/new...

Straight Shot: Hubble Investigates Galaxy with Nine Rings

Bullseye! Researchers using Hubble found a massive galaxy rippling with nine star-filled rings after an “arrow,” the blue dwarf galaxy to its center-left, plunged through its core 50 million years ago. A thin trail of gas still links the pair: bit.ly/4hcX52n 🔭 🧪

A large galaxy is at center, and a significantly smaller galaxy is to its left. The large galaxy, nicknamed the Bullseye, is mostly face-on, but the top appears slightly tilted away. It has several rings. Its circular core is bright white at the very center, but light yellow overall. Going outward, there are gaps between the rings. The core is surrounded by two slightly lighter yellow rings, which also appear to be overlapping. The next ring is slightly more transparent and yellow. The two or three rings that are farther out are bluer, sometimes with blue clumps. The widest ring is also blue, but also the most transparent. At 9 o’clock is a small dwarf galaxy. It is about the same size as the yellow core of the Bullseye. The dwarf galaxy is blue, with many dots. It looks like the edge of the Bullseye might touch the dwarf galaxy. Both galaxies are set on the black background of space, which is dotted with a range of galaxies in different shapes, colors, and sizes.

New Paper! With tim miller, @avapolzin.bsky.social, and pieter van dokkum, we explore whether forward modeling+simulation based inference can provide a robust, likelihood-free way to estimate galaxy distances in the distance range of 2-20 Mpc (too close for hubble-flow)🧵 arxiv.org/abs/2407.04091

Thrilled to announce an event I've long been thinking about! Join us at Yale University for a "Hack Day Conference," in which a group of educators come together to build resources and exercises for teaching research methods in astronomy. See astrocodex.github.io for more.

After half a decade of getting to use this incredible facility, today I got to visit Keck! It was both awe inspiring to see the telescopes and instruments that have defined my time in astronomy, and eye opening to see how much work is needed to keep this place looking upward night after night.
