2 What we (don t) know about UHECRs We know: their energies (up to ev). their overall energy spectrum We don t know: where they are produced how they are produced what they are made off exact shape of the energy spectrum
3 Potential Sources Hillas plot: Gyro radius has to fit source size! Galactic < ev Supernovae neutron stars & stellar black holes Extragalactic >10 18 ev Supermassive black holes Gamma-Ray bursts Intergalactic shocks Top-down: decay of primordial superheavy particles (?) 1 EeV = ev
4 Radio Images of Cosmic Accelerators Cas A Cygnus A Fornax A NRAO/AUI 1.4, 5, & 8.4 GHz
5 The Pierre Auger Observatory
6 Auger: Clustering of UHECRs The beginning of charged particle astronomy! AUGER Collaboration (2007), Science 9. Nov. (2007)
7 Ultra-high Energy Cosmic Ray Spectrum? The Pierre Auger Collaboration, Physics Letters B (2010)
8 Auger Composition Results Depth of shower maximum in atmosphere Auger Data proton prediction prediction for iron nuclei Looks like CR primaries become more heavy. NB: HiRes experiment interprets this differently (=> only protons)
9 Cosmic Rays in the Radio νmoon S. Lafebre
10 Radio Astroparticle Physics: Cosmic Rays in atmosphere: Geosynchrotron emission ( MHz) Radio fluorescence and Bremsstrahlung (~GHz) Radar reflection signals (any?) VLF emission, process unclear (<1 MHz) Neutrinos and cosmic rays in solids: Cherenkov emission (100 MHz - 2 GHz) polar ice cap (balloon or satellite) inclined neutrinos through earth crust (radio array) CRs and Neutrinos hitting the moon (telescope)
11 LOFAR Cosmic Ray KSP: Main Goals Understand High-Cosmic Rays Measure and fully characterize radio signals of extensive air showers (e.g., reference calibration for LOFAR and AUGER). Understand effects of and on lightning Use radio technique in transition region from Galactic to extragalactic CRs to clarify their nature (i.e., composition) Search for radio flashes from the moon to characterize UHECR spectrum at highest energies (NuMoon) Develop the techniques to work on raw time series data on dipole-level (transient buffer board & tied-array beam) in near field and far-field. Science Synergy with other KSP Transients: Identify and understand other sporadic signals ( RFI, lightning, SETI, astrophysical sub-ms pulses, e.g. giant pulses) Survey: Identify sources of UHECRs
12 Coherent Geosynchrotron Radio Pulses in Earth Atmosphere Earth B-Field ~0.3 G UHECRs produce particle showers in atmosphere Shower front is ~2-3 m thick ~ wavelength at 100 MHz e ± emit synchrotron in geomagnetic field Emission from all e ± (N e ) add up coherently Radio power grows quadratically with N e coherent E-Field E total =N e *E e Power E e 2 N e 2 GJy flares on 20 ns scales Falcke & Gorham (2003), Huege & Falcke (2004,2005) Tim Huege, PhD Thesis 2005 (MPIfR+Univ Bonn

15 Imaging of CR radio pulses with LOPES A. Nigl 2007, PhD Horneffer, LOPES30 event See also Falcke et al. (LOPES collaboration) 2005, Nature, 435, 313
16 Nanosecond Radio Imaging in 3D Off-line correlation of radio waves captured in buffer memory We can map out a 5D image cube: 3D: space 2D: frequency & time Image shows brightest part of a radio airshower in a 3D volume at t=t max and all freq. Actual 3D radio mapping of a CR burst No simulation! Bähren, Horneffer, Falcke et al. (RU Nijmegen)
17 UHE Neutrino detection needs large detector volumes! Auger: A eff =3000 km 2, Moon: A eff = km 2 Back to the moon

28 LOFAR Air Shower Array Layout: 5 clusters of 4 particle detectors in LOFAR core RFI measurements in ASTRON s antenna chamber Hardware & DAQ software is ready, testing under way, installation is next Will provide CR triggers to core stations
29 Synergies with other KSPs Technical: Identification of steady nearby and transient RFI sources Dipole-based antenna calibration and monitoring (gain, polarization) TBB software (mainly with TKP) Scientific; TKP: FRATs triggering and identification of Fast Radio Transients Surveys: Make survey products accessible to CR community Catalog of radio sources with estimates of sizes, magnetic fields, jet powers
30 Summary & Conclusions We want to explore the fastest time scales in LOFAR (down to 5ns) and develop novel techniques in radio astronomy Real-time triggering Transient Buffer-Board (TBB) utilization 3D all-sky imaging on buffered data (1sec observation needs 1TB of data to be processed ) Transient signal extraction detect airshowers from UHECRs between and ev determine radio properties with unprecedented quality (e.g., input for AUGER) determine precisely energy and composition in the suspected transition region form Galactic to Extragalactic CRs search for UHECRs and Neutrinos >10 21 ev hitting the moon Verify GZK-cutoff at the very least place the best limits on super-gzk CRs and neutrinos (which SKA will surely detect) investigate and search for other sub-second signals in buffered data and collaborate with Transient KSP Giant pulses of pulsars coherent burst from exploding neutron stars, etc. Lightning SETI (One Second All-Sky Survey) provide a catalog of northern UHECR source candidates with Survey KSP.
