  1. SETI By means of the Water MASER Radio-Emission at 22 GHz C.B.Cosmovici, IAPS / INAF Roma

  2. Water Maser emission during the Jupiter impact of Comet Shoemaker-Levy 9

  3. Comparative spectra of Epsilon Eridani: on the left hand the data acquired with the SPECTRA-2 backend show a clear detection with a SNR > 4; on the right hand, the same target was simultaneoulsy acquired with the old spectrometer MSPEC0 used for the Jupiter – Comet impact Both spectra were obtained by means of a similar instrumental and antenna setup. Please note that MSPEC0 was not able to detect any visible feature.

  4. Spectrum of the exoplanetary target Lalande 21185 observed at a frequency of 22 GHz, with the Noto INAF-IRA radiotelescope.

  5. Gliese 581, Noto, 30-08-2012. Boxcar filter. SNR = 5, FWHM=44kHz, vrad=0.4 km/s

  6. Present and FutureExtrasolar Planet Search • Optical Spectroscopy: gravitational wobbling • Optical Photometry I: occultation • Optical Photometry II: gravitational microlensing • Radio : MASER Emission • Space Interferometry: direct imaging
