Observations of the infant Universe have shown that the most distant galaxies discovered so far host black holes that are extremely massive, characterized by thousand of billions solar masses. These objects, known with the name of "quasars"; are generally discovered through the intense X-ray radiation they emit. The mechanism responsible for the formation of these black holes is still not known. To unveil this mystery and fully understand their origin and evolution, it would be necessary to detect their lower mass ancestors.

A lightning inferno at the event horizon of a massive black hole

Results published by the Science journal on November 6, 2014 show a powerful flare of high-energy gamma-radiation from the galaxy IC 310 in the Perseus Cluster, at 260 million light years from earth. This flare was observed with the twin 17-m telescopes of the MAGIC telescope at La Palma/Canary Islands. Ancillary observations with the European VLBI Network - EVN, funded by the EU project RadioNet3, show a remarkable straight plasma jet emerging from the vicinity of a supermassive black hole at the centre of the galaxy, in a region smaller than a light year.

WP3 - RadioNet3 funding allocation - Call for Proposals

RadioNet3 provides financial support to workshops and conferences through WP3, the Science Working Group. To ensure proper allocation of the remaining fundings a Call for Proposals is being issued. Proposals are now accepted for meetings, conferences and workshops taking place in the period 1 January – 30 September 2015.

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.
