Radio astronomy across Europe Wilfred Frieswijk* & ERATec Network Activity [email protected] * ASTRON Netherlands Institute for Radio Astronomy Abstract Europe has a long and outstanding history in radio astronomy. It currently hosts numerous of world-class facilities spread around the globe, some of which well-known, others being less familiar. The map below gives an overview of associated radio observatories accessible for the general astronomical community.
Trans-national access (TNA) Capabilities The objectives of the Transnational Access portion of RadioNet3 are ERATec The receivers available on the various • to draw together all of the European radio facilities under one umbrella; The main activity of the RadioNet3 telescopes operate in the radio regime, • to enable the European user community to have easy and transparent European Radio Astronomy Technical covering frequencies from ~10 MHz access to the entire range of facilities; Forum is to organise and support to 1 THz. With dish-sizes ranging • to offer the European user community an integrated, professional and meetings and workshops that help to from ~10 to 100 meters and baselines consistent level of user support. identify synergies and develop up to >1000 kilometers, spatial complementary capabilities at the website: http://www.radionet-eu.org/transnational-access resolutions can be achieved down to observatories, to determine how the sub-arc-second scales, thus matching pooling of resources might lead to those obtained at infrared- and optical Open time common solutions for common Most of the observatories provide telescope time to the general astronomical wavelengths. problems and to share best practice. community through "open access" calls.
