Where Did All This Dust Come From?
How did our galaxies get so dusty so fast? Come with us today to do some early-epoch spring cleaning.
The “Rhythm” of the Interstellar Medium
How does the gas in galaxies keep pace with star formation?
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.
Dawn of the Red Monsters
Today’s bite reports the discovery of the most distant red galaxy ever confirmed!
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.
