A sneak peek into early universe star formation with Boötes I
Today’s authors hunt for evidence of a universal IMF using JWST observations of local relic galaxy Boötes I!
Guest: Re‑envisioning Galaxy Morphology with Sparse Autoencoders
Euclid is delivering millions of galaxy images, far too many for humans to classify by hand. A new approach uses sparse autoencoders to uncover the hidden morphological features inside deep learning models, revealing both familiar structures and entirely new ones.
The “Rhythm” of the Interstellar Medium
How does the gas in galaxies keep pace with star formation?
Too Massive, Too Early… and Still Not Massive Enough?
What if JWST’s early massive galaxies are not overestimated, but underestimated? A bottom-heavy IMF could hide tons of mass in faint stars.
Guest: Teaching Machines to Spot Star‑Forming Clumps in Galaxies
Clumpy galaxies dominate the early universe, yet their local counterparts are hard to find. A new machine‑learning approach learns to spot these hidden clumps and opens the door to studying them in far greater detail.
Blast from the Past: Determining a Distance to I Zwicky 18
Take a walk down memory lane with I Zwicky 18, which could be the key to unlocking the secrets of the early universe.
