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…

MAGOS: Hot Cores in the LMC — Exploring Subsolar Chemistry in the Large Magellanic Cloud
Introduction: A Subsolar Laboratory for Star Formation The MAGellanic Outflow And Chemistry Survey (MAGOS) opens a window into how massive stars form and how their surrounding chemistry unfolds under subsolar metallicity. Focusing on the Large Magellanic Cloud (LMC), a nearby dwarf galaxy with about half the Sun’s metallicity, the survey targets hot molecular cores around…

MAGOS: Hot Cores in the LMC — A Subsolar Chemistry Study
Introduction: Why the LMC Matters for Hot Core Studies The MAGellanic Outflow And Chemistry Survey (MAGOS) targets the Large Magellanic Cloud (LMC) to probe hot cores around massive protostellar objects under subsolar metallicity. The LMC’s proximity offers a unique laboratory to study how chemistry and early star formation unfold when heavy elements are less abundant…

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…
