Decision on the southern site of CTA at the end of the year
Chile and Namibia as well as Argentina as a third option have been selected from the candidates on the southern hemisphere for concrete negotiations. This has now been decided by representatives of the funding countries based on the recommendations of an independent site selection committee.
On the 10th April 2014, the 12 country delegates mandated by their governments to decide about the start of site negotiations for CTA met in Munich. They took note of the report of the international Site Selection Committee (SSC) and thanked the members of the SSC as well as the CTA consortium for their extensive inputs on the merits of the proposed sites.
The delegates representing Argentina, Austria, Brazil, France, Germany, Italy, Namibia, Poland, Spain, South Africa, Switzerland and the UK decided, based on the 75% majority required, to start the negotiations on the two sites in the southern hemisphere, namely Aar in Namibia and ESO* in Chile, keeping Leoncito in Argentina as a third option. After negotiations finally one site will be selected at the end of the year. With the selection of the potential telescope sites in the southern hemisphere an important step towards the realization of the international Cherenkov Telescope Array has been made.
As far as the northern site of the CTA Observatory is concerned – candidate sites are located in Mexico, Spain and the USA - further considerations are necessary.Therefore, the delegates decided to postpone their decision and to ask the CTA board of agency representatives – the Resource Board - to take this forward.The decision for the negotiations about the northern hemisphere site will be taken as soon as possible.
“We are very happy that this important step has been reached” said B. Vierkorn-Rudolph, chair of the CTA Resource Board. “CTA will be a unique large-scale infrastructure for astronomy - with this decision we now can start the negotiations with the potential site countries in the southern hemisphere and advance the implementation of CTA”. The spokesperson of the CTA Consortium, Professor Werner Hofmann said “The site choice is on the critical path towards implementing CTA; this decision represents a major step forward and we appreciate very much the engagement and support of the funding agencies and the country delegates involved in the decision”.
CTA – the Cherenkov Telescope Array – is a multinational, world-wide project to construct a unique instrument exploring the cosmos at the highest photon energies. Over 1000 scientists and engineers from 5 continents, 28 countries and over 170 research institutes participate in the CTA project. CTA will provide an order-of-magnitude jump in sensitivity over current instruments, providing novel insights into some of the most extreme processes in the Universe.
CTA will consist of over 100 Cherenkov telescopes of 23-m, 12-m and 4-m dish size located at one site in the southern and a smaller site in the northern hemisphere. Potential candidate sites have been identified in the northern and southern hemisphere. Extensive studies of the environmental conditions, simulations of the science performance and assessments of costs of construction were conducted. The Site Selection Committee, composed of international experts in the evaluation of sites for astronomical observatories, has reviewed the studies and provided an independent assessment of the various candidate sites.

Subaru Telescope helps pinpoint origin of ultra-high energy neutrino

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
