Neutrino Astronomy at the South Pole
IceCube is currently being built deep in the glacial ice beneath the South Pole. In its second year of construction, it is already larger than its predecessor, AMANDA. AMANDA continues to collect high energy neutrino and muon data as an independent detector until it is integrated with IceCube. After introducing both detectors, recent results from AMANDA and a status report on IceCube are presen...
متن کاملMagnetic signature of the lunar South Pole-Aitken basin: Character, origin, and age
[1] A new magnetic map of the Moon, based on Lunar Prospector magnetometer observations, sheds light on the origin of the South Pole-Aitken basin (SPA), the largest and oldest of the recognized lunar basins. A set of WNW-trending linear to arcuate magnetic features, evident in both the radial and scalar observations, covers much of a 1000 km wide region centered on the NW portion of SPA. The so...
متن کاملHigh-resolution local magnetic field models for the Martian South Pole from Mars Global Surveyor data
We present two high-resolution local models for the crustal magnetic field of the Martian south polar region. Models SP130 and SP130M were derived from three-component measurements made by Mars Global Surveyor at nighttime and at low altitude (<200 km). The availability area for these data covers the annulus between latitudes −76∘ and −87∘ and contains a strongly magnetized region (southern par...
متن کاملThermal anomaly in Enceladus’ South Pole subsurface
On November 6, 2011, during the E16 flyby, the Cassini Radar had a unique opportunity to closely observe Enceladus in both its active and passive modes of operation. The E16 swath aimed at about 66°S, close to the active South polar rifted area. In this paper, we show that the radiometry data collected during this flyby revealed brightness temperatures much higher than expected, pointing to a g...
متن کاملEnceladus ’ South Pole : Conduction , Radiation , and Conduits
Introduction: In 2005, Cassini's Composite Infra-red Spectrometer (CIRS) detected a heat signature from the southern hemisphere of Saturn's Moon En-celadus and matched it to four fractures termed 'tiger stripes' and their associated plumes 1. Much study has been dedicated to constraining the output, with values ranging from ~ 3-5 GW 2,3 up to 15.8 GW 4 ; work is still being done to understand t...
