Studying bubbles from the early Universe: an efficient matched filter approach
In today’s bite, we talk about how one can efficiently measure bubbles of ionized gas that signal the epoch of reionization (EoR).
Back for Seconds: Evidence of Two Bursts of Star Formation in an Ultra-Faint Dwarf Galaxy
Reticulum II? More like Reticulum TWO distinct periods of star formation! Or at least that’s what new spectroscopic observations incdicate.
The Oldest Starlight
What if some of JWST’s most extreme high-redshift galaxy candidates aren’t galaxies at all, but the explosive deaths of the very first stars?
Global Calm, Local Chaos: How AGN-Driven Cosmic Rays Reshape Galaxies from the Inside
Massive galaxies all seem to end up quiet and quenched—but the physics inside them can look wildly different. This story explores how AGN-driven cosmic rays reshape galaxies from the inside out, changing local conditions without altering their ultimate fate.
It’s a bird! It’s a plane! It’s a neutrino observatory calibration source!

Zink First Author’s Institution: Erlangen Centre for Astroparticle Physics (ECAP), Friedrich-Alexander-University Erlangen-Nürnberg; Deutsches Elektronen-Synchrotron DESY Status: Published in the Journal of Instrumentation [open access] Neutrinos: Long-Distance Travelers If, in the middle of an intercontinental flight, you’ve ever looked out your window over, say, Greenland and wondered how this trip still isn’t over…just remember that your long-distance travels have nothing on the neutrino’s. This particle only very rarely interacts with other matter, so it can travel far across…
I Survived a Type Ia, and All I Got Was This Kick Velocity
Some type Ia supernovae involve a companion star that somehow survives the energetic explosion. What can we learn from these companions?

Navigating careers in astronomy
Career advice
Meet the AAS Keynote Speakers: Dr. Allison Strom
What can chemistry tell us about galaxies? The #AAS240 keynote speaker thinks it is basically the “DNA” of a galaxy. Find out more at Dr. Allison Strom’s talk!
