In the 1998-99 flight, BOOMERanG has produced maps of similar to 4% of the sky at high Galactic latitudes, at frequencies of 90, 150, 240 and 410 GHz, with resolution greater than or similar to 10'. The faint structure of the Cosmic Microwave Background at horizon and sub-horizon scales is evident in these maps. These maps compare well to the maps recently obtained at lower frequencies by the WMAP experiment. Here we compare the amplitude and morphology of the structures observed in the two sets of maps. We also outline the polarization sensitive version of BOOMERanG, which was flown early this year to measure the linear polarization of the microwave sky at 150, 240 and 350 GHz.

Abstract
In the 1998-99 flight, BOOMERanG has produced maps of similar to 4% of the sky at high Galactic latitudes, at frequencies of 90, 150, 240 and 410 GHz, with resolution greater than or similar to 10'. The faint structure of the Cosmic Microwave Background at horizon and sub-horizon scales is evident in these maps. These maps compare well to the maps recently obtained at lower frequencies by the WMAP experiment. Here we compare the amplitude and morphology of the structures observed in the two sets of maps. We also outline the polarization sensitive version of BOOMERanG, which was flown early this year to measure the linear polarization of the microwave sky at 150, 240 and 350 GHz.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
