How astronomers used the largest JWST survey to build a new map of the Universe
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.
Cosmic Cannibalism: When Stars Eat Their Planets
Some stars hide a strange ingredient in their atmospheres: the remains of a planet they devoured. It turns out to be more common than expected.
Hitchhiking PAHs Caught Catching a Ride on Galactic Winds
Get out of galaxies fast! The hitchhiker’s guide to galactic winds and their newfound polycyclic passengers.
Speeding Under Pressure on the Intergalactic Highway.
Using low frequency radio observations of the galaxy NGC 2276 with the uGMRT and LOFAR telescopes, the authors discover that the galaxy has a trail of gas about 100 kiloparsecs long! As the galaxy moves through the local ionised medium, the pressure exerted on it removes gas from it’s disk.
Guest: If you give a galaxy a starburst, it’ll probably quench the gas away
The distribution of post-starburst regions within galaxies is linked to diverse quenching pathways that are likely driven by mergers. Guest author, Emmy Wisz, explains how different star formation histories could be the key to understanding quenching mechanisms.
