JWST sheds Light on the Journey of Cosmic Icy Grains

JWST sheds Light on the Journey of Cosmic Icy Grains

Using the JWST, a team of researchers including Paola Caselli and Michela Giuliano from MPE, have probed deep into dense cloud cores, revealing details of interstellar ice that were previously unobservable. The study focuses on the Chamaeleon I region, using JWST’s NIRCam to measure spectroscopic lines towards hundreds of stars behind the cloud.

Massive black holes in low-mass galaxies: what happened to the X-ray Corona? 

Massive black holes in low-mass galaxies: what happened to the X-ray Corona?
 

Identifying massive black holes in low-mass galaxies is crucial for understanding black hole formation and growth over cosmic time but challenging due to their low accretion luminosities. Astronomers at MPE, led by Riccardo Arcodia, used the eROSITA X-ray telescope's all-sky survey to study massive black hole candidates selected based on variability in other wavelength ranges. Surprisingly, despite being flagged as accreting MBHs, the X-rays were weak and didn't match predictions from more massive AGN scaling relations. This discrepancy suggests either the absence of a canonical X-ray corona or the presence of unusual accretion modes and spectral energy distributions in these dwarf galaxy MBHs.

Webb Finds Plethora of Carbon Molecules Around Young Star

An international team of astronomers have used the NASA/ESA/Webb James Webb Space Telescope to study the disc around a young and very low-mass star. The results reveal the richest hydrocarbon chemistry seen to date in a protoplanetary disc (including the first extrasolar detection of ethane) and contribute to our evolving understanding of the diversity of planetary systems.

Cosmic dance of the ‘Space Clover’

Cosmic dance of the ‘Space Clover’

A group led by MPE has, for the first time, detected X-ray gas at the location of the cloverleaf ORC, an odd radio circle (ORC). The origin of ORCs is unknown; in the case of the cloverleaf ORC, the combined data from different wavelengths indicate that the emission is due to a merger of two small galaxy groups.

Weighing a Black Hole in the early universe

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

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.
