Optimized Trigger for Ultra-High-Energy Cosmic-Ray and Neutrino Observations with the Low Frequency Radio Array

K. Singh, M. Mevius, O. Scholten +100

When an ultra-high energy neutrino or cosmic ray strikes the Lunar surface a radio-frequency pulse is emitted. We plan to use the LOFAR radio telescope to detect these pulses. In t…

Lossy compression of weak lensing data

R. Ali Vanderveld, Gary M. Bernstein, Chris Stoughton +4

Future orbiting observatories will survey large areas of sky in order to constrain the physics of dark matter and dark energy using weak gravitational lensing and other methods. Lo…

Observing pulsars and fast transients with LOFAR

B. W. Stappers, J. W. T. Hessels, A. Alexov +91

Low frequency radio waves, while challenging to observe, are a rich source of information about pulsars. The LOw Frequency ARray (LOFAR) is a new radio interferometer operating in…

The power of Bayesian evidence in astronomy

C. R. Jenkins, J. A. Peacock

We discuss the use of the Bayesian evidence ratio, or Bayes factor, for model selection in astronomy. We treat the evidence ratio as a statistic and investigate its distribution ov…

Planck early results: first assessment of the High Frequency Instrument in-flight performance

Planck HFI Core Team, P. A. R. Ade, N. Aghanim +163

The Planck High Frequency Instrument (HFI) is designed to measure the temperature and polarization anisotropies of the Cosmic Microwave Background and galactic foregrounds in six w…

Planck Early Results. II. The thermal performance of Planck

Planck Collaboration, P. A. R. Ade, N. Aghanim +225

The performance of the Planck instruments in space is enabled by their low operating temperatures, 20K for LFI and 0.1K for HFI, achieved through a combination of passive radiative…
