After almost a decade of work, an international team of astronomers has published the most detailed images yet seen of galaxies beyond our own, revealing their inner workings in unprecedented detail. The images were created from data collected by the Low Frequency Array (LOFAR), a radio telescope built and maintained by ASTRON, LOFAR is a network of more than 70,000 small antennae spread across nine European counties, with its core in Exloo, the Netherlands. The first international LOFAR station, one of the six German stations, is been seated at MPIfR’s Effelsberg observatory (ASTRON Newsblog, August 17, 2021). more

On July 19, 2021, SOFIA, the NASA and DLR stratospheric observatory, landed at Faa'a International Airport, outside Papeete, Tahiti, French Polynesia, and will observe the southern sky from there for the next eight weeks. A total of 32 flights are planned through early September, including 20 with the German Receiver at Terahertz Frequencies (GREAT) built by the Max Planck Institute for Radio Astronomy and the University of Cologne (USRA News, July 20, 2021). more

Jets Pose Many Riddles

July 14, 2021

The super-energetic jets that shoot out of black holes are in the focus of a new DFG research group, being funded with 3.6 million euros.  The MPIfR is involved in two sub-projects: Bia Boccardi and J. Anton Zensus lead the sub-project “mm-VLBI studies of gamma-ray bright radio galaxies”, and J. Anton Zensus and Eduardo Ros participate in the project “jet physics one event horizon scales and beyond” led by Matthias Kadler and Christian M. Fromm in Würzburg (IDW Press Release Univ. Würzburg, July 14, 2021). more

As part of the FEEDBACK program based on observations with the GREAT receiver aboard SOFIA, built by MPIfR in cooperation with Cologne University, a team of researchers led by Maitraiyee Tiwari/UMD and including Rolf Güsten/MPIfR was able to produce the first high-resolution image of an expanding bubble of hot plasma and ionized gas in the star cluster Westerlund 2, one of the brightest and most massive star-forming regions in the Milky Way. The results were recently published in The Astrophysical Journal (UMD press release, July 14, 2021). more

In 2019, the EHT Collaboration published the first image of a black hole located at the centre of the galaxy M87. Now a collaboration team led by theoretical physicists at the Goethe University Frankfurt, including MPIfR scientists, have analysed data from the black hole M87* to test Albert Einstein's theory of general relativity. According to the tests, the size of the shadow from M87* is in excellent agreement with a black hole predicted by general relativity, but narrows the properties of black holes in other theories down. The publication in the current issue of Physical Review D is within the framework of the BlackHoleCam (BHC) project (EHT Press Release, May 20, 2021). more

Based on observations from the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China, an international research team led by Jumei Yao, including Michael Kramer from the MPIfR, found the first evidence for three-dimensional (3D) spin-velocity alignment in pulsars.The study was published in Nature Astronomy on May 6 (CAS-Press Release, May 07, 2021). more

Two international teams of astronomers including Ramesh Karuppusamy from MPIfR have narrowed-down the origin of the flashes produced in the fast radio burst FRB20180916B by examining them with the highest time resolution and at the lowest possible frequencies. These studies, using the Effelsberg 100-m telescope within the EVN network and the European LOFAR telescope network, have been published in Nature Astronomy and in The Astrophysical Journal Letters (JIVE Press Release, April 15, 2021). more

Observations of the interactions of massive stars with their environment are carried out in the SOFIA program FEEDBACK led by Nicola Schneider and Alexander Tielens, using the upGREAT receiver built by MPIfR and Univ. Cologne. Studies of the star-forming region RCW 120 in the southern sky show that stellar feedback positively influences star formation in the surrounding area. The results, under partizipation of MPIfR authors, are published in the April issue of the journal “Science Advances” (Press Release UzK April 13, 2021, in German language). more

A team from the DLR Institute for Optical Sensor Systems in Berlin with the participation of MPIfR scientists shows that SOFIA offers the possibility of better understanding the atmosphere of our home planet. To this end, the concentration of atomic oxygen in the Earth's mesosphere and lower thermosphere in an altitude range from 80 to 400 km was studied by high-resolution spectral measurements with the upGREAT instrument (DSI Press Release from April 01, 2021, in German Language, Original Paper in „Nature Journal Communications Earth and Environment“). more

On April 1, 2021, a special stamp will be issued to mark the 50th birthday of the telescope more
