Benoît Revenu (CNRS/IN2P3)19/06/2012, 17:00Invited TalksInvited TalkAfter 10 years of efforts, important progress have been made in the field of radio-detection of extensive air showers in the MHz range. The geomagnetic contribution has been proven to be dominant. A secondary process in the shower (probably related to the excess of charges in the shower) has also been detected. The correlation between the detected electric field and the nature and energy of...Go to contribution page

Maximilien Melissas (KIT, IEKP)19/06/2012, 17:40Overview TalkThe first phase of the Auger Engineering Radio Array (AERA) has been deployed in the fall of 2010. Currently, the array consists currently of 24 stations distributed over an area of 0.5 km$^2$. AERA has two different objectives. The first one is to measure cosmic-ray events and to provide the necessary data to improve our understanding of radio emission from air showers. The second objective...Go to contribution page

Mr Christian Glaser (RWTH Aachen)19/06/2012, 18:05Specialised TalkThe Auger Engineering Radio Array (AERA) is located within the Pierre-Auger Observatory and currently consists of 24 self-triggered radio stations. Observation of radio signals from cosmic rays is confirmed by the surface detector (SD) stations of the observatory which provide well calibrated information on the cosmic ray energies and arrival directions. The response of the radio stations has...Go to contribution page

Stefan Grebe (Radboud University Nijmegen)19/06/2012, 18:25Specialised TalkThe first stage of the Auger Engineering Radio Array has been deployed at the Pierre Auger Observatory in Argentina and is taking data. It measures radio signals in the MHz range from air showers induced by cosmic rays with energies above 10^17 eV. It is overlooked by the fluorescence telescopes and is located in a dense part of the particle detector array. This allows for cross-calibration of...Go to contribution page

Frank Schröder (Karlsruhe Institute of Technology (KIT))20/06/2012, 17:00Overview TalkLOPES is a digital antenna array at the Karlsruhe Institute of Technology, Germany, for cosmic-ray air-shower measurements. Triggered by the co-located KASCADE-Grande air-shower array, LOPES detects the radio emission of air showers via digital radio interferometry. We will summarize the status of LOPES and recent results concerning the understanding of the radio emission and the...Go to contribution page

Dr Marianne Ludwig (Karlsruhe Institute of Technology)20/06/2012, 17:25Specialised TalkIn the previous years, LOPES emerged as a very successful experiment measuring the radio emission from air showers in the MHz frequency range. In parallel, the theoretical description of radio emission was developed further and REAS 3.1 became a well-respected simulation Monte Carlo code. REAS 3.1 as well as CoREAS are based on the endpoint formalism, i.e. no assumptions on the emission...Go to contribution page

Mrs Nunzia Palmieri (Institut fuer Kernphysik (IKP), Karlsruhe Institute of Technology (KIT))20/06/2012, 17:45Specialised TalkIn the previous decades, remarkable progress has been made in the detection of electromagnetic emission from cosmic ray air showers. The LOPES experiment, a digital radio interferometer located at KIT (Karlsruhe Institute of Technology), obtained considerable results for the detection at MHz frequencies. Aiming to become competitive with the well-established investigation methods, radio...Go to contribution page

Pascal Lautridou (SUBATECH)20/06/2012, 18:05Overview TalkThe purpose of the CODALEMA experiment, installed at the Nançay Radio Observatory (France), is to study the radio-detection of cosmic rays of ultra high energy. Distributed over an area of 0.25 km2, the original device has a centralized acquisition, and uses in coincidence an array of particle detectors and an array of active dipoles. A new analysis of energy observables is presented from this...Go to contribution page

Anna Nelles (Radboud University Nijmegen)22/06/2012, 09:40Overview TalkLOFAR (the Low Frequency Array) is the largest radio telescope in the world for observing low frequency radio emission from 10 to 240 MHz. In addition to its use as an interferometric array, LOFAR is now routinely used to detect cosmic ray induced air showers by their radio emission. The LOFAR core in the Netherlands has a higher density of antennas than any other dedicated cosmic ray...Go to contribution page

Frank Schröder (Karlsruhe Institute of Technology (KIT))22/06/2012, 10:05Specialised TalkTunka-Rex (Tunka radio extension) will be an array of about 20 antennas at the Tunka experiment close to Lake Baikal in Siberia. The antennas will be connected directly to the data acquisition of the Tunka main detector, a 1 km² large array of 133 non-imaging photomultipliers observing the Cherenkov light of air showers in dark and clear nights. This allows to cross-calibrate the radio signal...Go to contribution page

Sebastian Boeser (U)22/06/2012, 10:25Specialised TalkWith its 1km3 in-ice sensor array complemented by a 1km2 surface array of ice-Cherenkov tanks for particle detection, the IceCube observatory is not only the largest neutrino telescope but also one of the world's most competitive instrument for studying cosmic rays in the PeV to EeV regime. In particular, studying high-energy muons from the shower core in coincidence with particle flux on the...Go to contribution page
