MAGOS: Hot Cores in the LMC Reveal Subsolar Chemistry in Star Formation
Overview: MAGOS maps hot cores in a metal-poor neighbor The Magellanic Outflow And Chemistry Survey (MAGOS) targets the Large Magellanic Cloud (LMC) to explore how massive protostellar environments develop under subsolar metallicity. By surveying a sample of hot cores around 30 massive protostellar objects, the study investigates the chemical inventory, excitation conditions, and spatiotemporal evolution…

Selective Feeding: How Supermassive Black Holes Skim Gas During Galaxy Mergers
Introduction: A New View of Black Hole Feeding Black holes are often portrayed as cosmic vacuum cleaners, devouring anything that strays too close. Yet recent observations with the Atacama Large Millimeter/submillimeter Array (ALMA) show that supermassive black holes (SMBHs) in merging galaxies do not always gorge on available gas. Instead, their appetite appears selective, channelling…
