A team of scientists from the Max Planck Institute for Extraterrestrial Physics has shed light on one of the most elusive components of the universe: the warm-hot intergalactic medium (WHIM). This "ghost" form of ordinary matter, long hypothesized but rarely detected, is thought to account for a significant portion of the universe's missing baryons — the matter that makes up stars, planets, and galaxies. more

Our Solar System dwells in a low-density environment called the Local Hot Bubble (LHB), filled by a tenuous, million-degree hot gas emitting dominantly in soft X-rays. A team led by scientists at the Max Planck Institute for Extraterrestrial Physics (MPE) used the eROSITA All-Sky Survey data and found a large-scale temperature gradient in this bubble, possibly linked with past supernova explosions that expanded and reheated the bubble. The wealth of the eROSITA data also allowed the team to create a new 3D model of the hot gas in the solar neighbourhood. The highlight of this work features the discovery of a new interstellar tunnel towards the constellation Centaurus, potentially joining our LHB with a neighbouring superbubble. more

Euclid reveals the first deep view into the cosmos, spanning an area of 500 full moons in the sky. more

An international group of astrophysicists, led by MPE scientists Marta Obolentseva, Alexei Ivlev, Kedron Silsbee, and Paola Caselli, have revisited the long-standing problem of evaluating the rate at which cosmic rays ionize gas in the interstellar medium. By combining available observational data for diffuse molecular clouds with novel developments in understanding the dust and gas distribution in these regions and applying numerical modeling, the scientists were able to compute the cosmic-ray ionization rate (or its upper limit) for a dozen nearby clouds. They showed that earlier estimates were a factor of ten too high. more

The Multi-AO Imaging Camera for Deep Observations (MICADO), a project led by MPE to provide a powerful high-resolution first light camera for ESO’s Extremely Large Telescope (ELT), has passed its final design review, marking an important milestone on its road to operation later this decade. Once complete, MICADO will offer astronomers the ability to take images of the Universe at an unprecedented depth. more

Dr. Matthias Kluge from the Max Planck Institute for Extraterrestrial Physics (MPE) has received the 2024 Ludwig Biermann Award from the German Astronomical Society. This award recognizes his significant contributions to astrophysics, especially his pioneering research on galaxy clusters. Kluge's efforts with the eROSITA telescope on the SRG mission have been crucial in identifying and analyzing 12,000 galaxy clusters, deepening our knowledge of the cosmic web. more

The galaxy PJ0116-24 lives about 10 billion years ago and appears about 10,000 times brighter in the infrared than our Milky Way. It belongs to a rare population of so-called hyper-luminous infrared galaxies (HyLIRG), which are usually formed by the collision of several galaxies. Members of the Infrared Group at the Max Planck Institute for Extraterrestrial Physics (MPE) including Daizhong Liu and Natascha M. Förster Schreiber, together with researchers from the European Southern Observatory (ESO) and other international institutes, now showed that a HyLIRG can also arise in a massive turbulent rotating disk within a single galaxy, where the gas is organized in a structured way. This finding was made possible through new observations including from the novel ERIS instrument at the ESO Very Large Telescope, built by a consortium also led by the MPE Infrared Group, and strong magnification caused by a massive elliptical galaxy that lies between us and PJ0116-24. This galaxy acts as a gravitational lens stretching PJ0116-24 in an “Einstein ring” and making it appear 17 times brighter. more

Using the JWST, a team of researchers including Paola Caselli, Barbara Michela Giuliano and Basile Husquinet 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. more

Guillaume Bourdarot, a postdoctoral researcher from the Infrared Group, received a Nobel Laureate Fellowship at the 75th Annual General Meeting of the Max Planck Society. Nominated by Nobel laureate Reinhard Genzel, Bourdarot is recognized for his work on high-resolution infrared observations of astrophysical objects.  more

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. more

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. more
