RadioNet3 report submitted to EU

Overall the RadioNet3 project is in very good shape and it is quite impressive to see so many high-end deliverables coming out of this programme.

Type Ia supernovae stem from the explosion of white dwarfs coupled with twin stars

A study discards the possibility that the progenitor of the type Ia SN 2014J might have stemmed from the explosions of a white dwarf nourished by a normal star. Were these conclusions to become generalized, the use of type Ia supernovae “cosmological standard candles” might need to be revised.

RadioNet3 supported radio astronomers team observed the initial conditions of massive star formation

Massive stars are responsible not only for some of the most spectacular phenomena in the Universe, but also for the production of heavy elements, key for the origin of life.
  

EVN measurements show no evidence for radio emission from the Type Ia SN 2014J

A team led by Miguel A. Pérez-Torres has used the FP7 RadioNet3 transnational access programme to look for a radio emission in the recently discovered supernova Type Ia SN2014J. The newly made observations with a total of 8 EVN stations show that there is no evidence of such emission in the surrounding region.

22nd Working Meeting of the European VLBI Group for Geodesy and Astrometry

The “First Announcement” of the 22nd Working meeting of The European VLBI Group for Geodesy and Astrometry was recently released. The meeting will be held on May 17-21, 2015, on Sao Miguel, Azores.

3rd RadioNet3 European Radio Astronomy Technical Forum Workshop - Revised Announcement

The 3rd RadioNet3 European Radio Astronomy Technical Forum Workshop "Metrologies at Radio Astronomy Antennas" is announced to take place on September 1- 2, 2014 at Chalmers University in Gothenburg, Sweden and not as a Special Session of the 2014 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting as previously planned.

First fringes for the Sardinia Radio Telescope

Fringes were found in an interferometric observation done on 27 January 2014 between the Sardinia Radio Telescope and the Medicina 32m dish of 3C454.3 at 22GHz. These are the first fringes found with the SRT, a 64m dish inaugurated in September 2013.

RadioNet3 sponsor of the 40th COSPAR Scientific Assembly

The 40th COSPAR Scientific Assembly will take place in Moscow, Russia, on 2 – 10 August 2014 (http://www.cospar-assembly.org). RadioNet3 sponsors the Event E1.10 “The sharpest view of the radio universe – results from the RadioAstron (SPEKTR-R) mission”. The request for a contributed paper to this event is now available.

RadioNet3 ERATec Special Session at the IEEE-AP/URSI Symposium

The 3rd RadioNet3 European Radio Astronomy Technical Forum Workshop “Metrologies at Radio Astronomy Antennas” has been announced. It will be organized as a Special Session of the 2014 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, which will be held at the Memphis Convention Center in Memphis, Tennessee, USA, July 6th – 12th 2014.

ERC Synergy Grant to image event horizon of black hole

The European Research Council (ERC) has awarded 14 Million Euros to a team of European astrophysicists to construct the first accurate image of a black hole. The team will test the predictions of current theories of gravity, including Einstein's theory of General Relativity. The funding is provided in the form of a ‘Synergy Grant’, the largest and most competitive type of grant of the ERC.
