Stronger Tests of Einstein's Theory of General Relativity with Binary Neutron Stars

October 24, 2017
Einstein's theory of general relativity has withstood 100 years of experimental scrutiny. However, these tests do not constrain how well the very strong gravitational fields produced by merging neutron stars obey this theory. Scientists at the Max Planck Institutes for Gravitational Physics and for Radio Astronomy studied two foremost tools for testing the strong-field regime of gravity – pulsar timing and gravitational-wave observations – and demonstrated how combining these methods can put alternative theories of general relativity to the test (AEI Press Release 24 October 2017).

EVN telescopes zoom in on the first detection of gravitational waves produced by colliding neutron stars

October 16, 2017
For the first time, scientists have directly detected gravitational waves - ripples in space and time - in addition to light from the spectacular collision of two neutron stars. This marks the first time that a cosmic event has been viewed in both gravitational waves and light. The EVN collaboration of European radio telescopes including the 100-m Effelsberg telescope has been involved in the observing campaign, looking for radio emission from the colliding neutron stars witnessed by LIGO and Virgo.

Einstein Inside

August 22, 2017
The Deutsches Museum Bonn (Ahrstraße 45) presents the exhibition „Einstein Inside“, celebrating  100 years of Einstein’s Theory of General Relativity. The exhibition gives a colorful and entertaining introduction into the world of general relativity and its importance for current research. It was created by astrophysicists from Tübingen University. The Max Planck Institute for Radio Astronomy is one of the participating institutes. [more]

Cosmic Magnifying Lens Reveals Inner Jets of Black Holes

August 15, 2017
An international team of astronomers including J. Anton Zensus from the Max Planck Institute for Radio Astronomy in Bonn, Germany, found evidence for a bizarre lensing system in space, in which a large assemblage of stars is magnifying a much more distant galaxy containing a jet-spewing supermassive black hole. The discovery provides the best view yet of blobs of hot gas that shoot out from supermassive black holes. The astronomers used Caltech's Owens Valley Radio Observatory (OVRO) for their observations.

Kia ora SOFIA – Airborne observatory welcomed in New Zealand

June 23, 2017
The airborne observatory SOFIA, a joint DLR/NASA observatory, will use three instruments (GREAT, FIFI-LS and FORCAST) to investigate the southern skies during a total of 25 observation flights from 26 June to 10 August 2017. The spectrometer GREAT with its extensions upGREAT and 4GREAT was built by a German team led by Rolf Güsten from the Max-Planck-Institut für Radioastronomie in Bonn. This is SOFIA’s fourth stationing in New Zealand (DLR News, 23 June 2017). [more]

MeerKAT goes online

July 19, 2016
The MeerKAT First Light image of the sky reveals previously unseen galaxies, showing the potential of MeerKAT and SKA. On Saturday, July 16, MeerKAT achieved its first significant scientific milestone by using 16 of its eventual 64 dishes integrated into a working telescope array. In a small patch of sky covering less than 0.01 percent of the entire celestial sphere, the MeerKAT First Light image shows more than 1300 galaxies in the distant Universe, compared to 70 known in this location prior to MeerKAT (SKA Press Release, July 18, 2016).

SOFIA flying observatory with three instruments in New Zealand

June 07, 2016
SOFIA is in New Zealand for the third time – it visited the country in 2013 and 2015 as well. On 6 June 2016, the joint NASA and German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) flying observatory landed at Christchurch Internationl Airport at 01:37 CEST (11:37 local time). The Stratospheric Observatory for Infrared Astronomy (SOFIA) will embark on the first scientific flight of this year's campaign in the southern hemisphere on 9 June. Equipped with the German-built remote infrared spectrometers GREAT (German Receiver for Astronomy at Terahertz Frequencies) and FIFI-LS (Field-Imaging Far-Infrared Line Spectrometer), as well as with the US FORCAST (Faint Object InfraRedCAmera for the SOFIA Telescope) SOFIA will conduct a total of 25 observation flights until 20 July 2016 (DLR News, June 07, 2016).

SOFIA/GREAT Detection of Atomic Oxygen in the Martian Atmosphere

May 06, 2016
Atomic oxygen is a key component in regulation of energy and mass exchanges within the Martian atmosphere. Neutral atomic oxygen (O I) was detected in the Martian atmosphere at a frequency of 4.7 THz (63 μm) on 14 May 2014 using the high-frequency channel of the far-infrared heterodyne spectrometer GREAT (German Receiver for Astronomy at Terahertz Frequencies onboard SOFIA. GREAT principal investigator is Rolf Güsten from MPIfR Bonn. Originalveröffentlichung: L. Rezac et al. 2015, Astronomy & Astrophysics 580, L10 (NASA Feature, May 06, 2016) [more]

Horsehead Nebula: Velocity Resolved [C II] Map using SOFIA/upGREAT

March 31, 2016
The SOFIA science team has published a new map of the horsehead Nebula (IC 434), an interstellar cloud in Orion. The data in the spectroscopic line of ionized carbon (C+) resp. [CII] were observed with the upGREAT instrument onboard SOFIA which was built by MPIfR/Bonn and KOSMA/University of Cologne under the leadership of Rolf Güsten/MPIfR. (SOFIA Science Center) [more]

First 3 mm-VLBI imaging of the two-sided jet in Cygnus A

March 31, 2016
For the first time, VLBI images have been obtained of the archetypal radio galaxy Cygnus A at the frequency of 86 GHz. The high spatial resolution gives insight into the transverse width profile at the onset of the two-sided flow. The publication from an MPIfR research team led by Biagina Boccardi appears as highlight in the present issue of the research journal "Astronomy & Astrophysics": A&A 588, L9 (2016). [more]

Bonn-bound PAF pops by Parkes

February 12, 2016
A special receiver system (phased array feed  or PAF receiver) developed for the Effelsberg 100m radio telescope in Germany has been built by CSIRO in Australia through an agreement with the Max Planck Institute for Radio Astronomy (MPIfR). “The PAF is a key technology for future astronomy, and an exciting step towards a new generation of receivers with capabilities not previously possible,” says Gundolf Wieching, head of the Electronics department at MPIfR. “The installation of the PAF on Parkes is a continuation of the long collaboration between the ATNF and MPIfR, and I'm looking forward to being able to use this new technology to look at the northern sky, from Effelsberg."(ASKAP News) [more]
