Probing the jet base of M87’s supermassive black hole

New observations with the Event Horizon Telescope (EHT) provide fresh insights into where the powerful jet of the galaxy Messier 87 (M87) originates. Using recently published 2021 EHT data, an international team led by researchers from MPIfR, NRAO, and CITA has identified strong evidence for a compact region close to the black hole that likely [...]

SKA-Mid Telescope in South Africa Achieves “First Fringes”

The SKA Observatory’s SKA-Mid telescope in South Africa has reached a major milestone by achieving “first fringes”, confirming that the array is operating as an interferometer for the first time. Using two of its 15-metre dishes, SKA-Mid successfully combined signals from a distant radio galaxy around 2.6 billion light years away. This achievement demonstrates that [...]

Astronomers Pinpoint the Origin of a Repeating Fast Radio Burst

Astronomers using the European VLBI Network (EVN) have precisely located a repeating fast radio burst, FRB 20190417A, confirming that it originates from a compact, persistent radio source. By combining signals from radio telescopes across Europe and beyond at JIVE, the team achieved milliarcsecond precision, directly linking the brief radio flashes to a constantly emitting source. [...]

University of Bielefeld: Research Position (PhD student) (m/f/d)

The ErUM-IFT-2 project "Information Field Theory for Experiments at Large Research Facilities" has a PhD opening in the field of data-intensive radio astronomy. Methods of information field theory will be used to characterise the properties of radio antennas as used in modern radio interferometers (e. g., MeerKAT, LOFAR, SKA). The goal is to establish accurate [...]

Mysterious Million Solar-Mass Dark Object Found in Distant Universe

Astronomers have discovered an invisible object with a mass of about one million Suns that doesn’t fit any known cosmic structure. Using gravitational lensing and data from radio telescopes around the world, including the Green Bank Telescope (GBT), the Very Long Baseline Array (VLBA), and the European VLBI Network (EVN)—the team revealed a compact core (likely [...]

EU project SPECTRUM public consultation — feedback on SRIDA & Technical Blueprint

SPECTRUM is a Horizon Europe project bringing together leading organisations from Radio Astronomy, High-Energy Physics and e-Infrastructure providers to define a shared vision for a European compute and data continuum. As part of this effort, the draft versions of two main SPECTRUM outputs are now open for feedback: Strategic Research, Innovation and Deployment Agenda (SRIDA) [...]
