Breakthrough in High-Frequency VLBI with Shared-Optical-Path Frequency Phase Transfer

A new study led by MPIfR (Guang-Yao Zhao) demonstrates a major advance in millimeter VLBI: the first single-optical-path frequency-phase-transfer (FPT) observations between 86 GHz and 258 GHz on an 8600 km baseline. Using APEX’s newly commissioned N3AR receiver in dual-band mode and simultaneous observations with the IRAM 30 m telescope — both supported by RadioNet — [...]

Unveiling ALMA Band 2 workshop – call for abstract submission open

Installation and testing of the ALMA Band 2 receivers, covering 67 to 116 GHz, is currently underway. In anticipation of Band 2 being offered in the near future, the ALMA Band 2 workshop brings together astronomers and ALMA/ARC staff to discuss the new potential for various scientific fields. We plan to have a dedicated session [...]

Discovery of a newborn Solar System

Astronomers have observed the earliest stages of planet formation around the baby star HOPS-315, 1,300 light-years away. The international team, including scientists from Chalmers University of Technology and Onsala Space Observatory, analyzed chemical signals that reveal the first building blocks of rocky planets. Using data from the James Webb Space Telescope and the ALMA observatory, [...]

An Exceptional Einstein Cross Reveals Hidden Dark Matter

Astronomers have observed a rare Einstein Cross with a bright central fifth image, produced by gravitational lensing of the distant galaxy HerS-3 (11.6 billion light-years away). Observations with NOEMA (IRAM, France), ALMA, VLA, and Hubble show that the five-image configuration can only be explained by a massive dark matter halo in the foreground galaxy group. [...]
