Candidate Identification and Interference Removal in SETI@home

Eric J. Korpela, Jeff Cobb, Matt Lebofsky +5

SETI@home, a search for signals from extraterrestrial intelligence, has been recording data at the Arecibo radio telescope since 1999. These data are sent via the Internet to the p…

A brief history of the search for extraterrestrial intelligence and an appraisal of the future of this endeavor

Stuart Bowyer

The idea that credible searches for Extra-Terrestrial Intelligence (ETI) could be carried out were laid out in detail in the (now classic) paper by Morrison and Cocconi (1959). The…

Millisecond Imaging of Radio Transients with the Pocket Correlator

C. J. Law, G. Jones, D. C. Backer +5

We demonstrate a signal processing concept for imaging the sky at millisecond rates with radio interferometers. The "Pocket Correlator" (PoCo) correlates the signals from multiple…

Detection and Imaging of the Crab Nebula with the Nuclear Compton Telescope

M. S. Bandstra, E. C. Bellm, S. E. Boggs +17

The Nuclear Compton Telescope (NCT) is a balloon-borne Compton telescope designed for the study of astrophysical sources in the soft gamma-ray regime (200 keV--20 MeV). NCT's ten h…

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…

Planck Early Results: The Planck mission

Planck Collaboration, P. A. R. Ade, N. Aghanim +272

The European Space Agency's Planck satellite was launched on 14 May 2009, and has been surveying the sky stably and continuously since 13 August 2009. Its performance is well in li…
