Weighing a Black Hole in the early universe
With the upgraded GRAVITY-instrument at the ESO VLTI, a team of astronomers led by the Max Planck Institute for Extraterrestrial Physics has determined the mass of a Black Hole in a galaxy only 2 billion years after the Big Bang. With 300 million solar masses, the black hole is actually under-massive compared to the mass of its host galaxy, indicating that at least for some systems there might be a delay between the growth of the galaxy and its central black hole.
Webb shines light on early interstellar grain growth
In a groundbreaking study, the James Webb Space Telescope (JWST) observed the early stages of the growth of dust grains in the dense Chamaeleon I cloud. These cold dust grains have accumulated molecular solids on their surface early in the process leading to star formation, challenging previous assumptions on where and when grain growth occurs.
