XMM-Newton observation of the Seyfert 1.8 ESO 113-G010: Discovery of a highly redshifted iron line at 5.4 keV
Turner, T. J.; Uttley, P.; Porquet, D. +1 more
We present a spectral analysis of the Seyfert 1.8
Seismology of the solar atmosphere
Cacciani, Alessandro; Jefferies, Stuart M.; Finsterle, Wolfgang +4 more
We describe a new instrument for seismically probing the properties of the Sun's lower atmosphere, and present some first results from an observational campaign carried out at the geographic South Pole during the austral summer of 2002/2003. A preliminary analysis of the data (simultaneous, high-cadence observations of the velocity signals from th…
L183 (L134N) Revisited. II. The dust content
Miville-Deschênes, M. -A.; Lagache, G.; Pagani, L. +6 more
We present here a complete dust map of
Observations and temperatures of Io's Pele Patera from Cassini and Galileo spacecraft images
Turtle, Elizabeth P.; Radebaugh, Jani; McEwen, Alfred S. +4 more
Pele has been the most intense high-temperature hotspot on Io to be continuously active during the Galileo monitoring from 1996-2001. A suite of characteristics suggests that Pele is an active lava lake inside a volcanic depression. In 2000-2001, Pele was observed by two spacecraft, Cassini and Galileo. The Cassini observations revealed that Pele …
Search for spatial variation in the jovian 15N/ 14N ratio from Cassini/CIRS observations
Nixon, Conor A.; Irwin, Patrick G. J.; Fouchet, Thierry +4 more
We have used the spectra obtained by the Composite Infrared Spectrometer (CIRS) onboard the Cassini spacecraft to search for latitudinal variation in the 15N/ 14N ratio on Jupiter. We found no variations statistically significant given the observational and model uncertainties. The absence of latitudinal variations demonstrat…
Weak Lensing from Space. II. Dark Matter Mapping
Refregier, Alexandre; Ellis, Richard; Massey, Richard +8 more
We study the accuracy with which weak-lensing measurements could be made from a future space-based survey, predicting the subsequent precision of three-dimensional dark matter maps, projected two-dimensional dark matter maps, and mass-selected cluster catalogs. As a baseline, we use the instrumental specifications of the SuperNova/Acceleration Pro…
The Southern Proper Motion Program. III. A Near-Complete Catalog to V=17.5
Girard, Terrence M.; van Altena, William F.; López, Carlos E. +3 more
We present the third installment of the Yale/San Juan Southern Proper Motion Catalog, SPM3. Absolute proper motions, positions, and photographic BV photometry are given for roughly 10.7 million objects, primarily stars, down to a magnitude of V=17.5. The catalog covers an irregular area of 3700 deg2, between the declinations of -20° and…
On the origin of field-aligned beams at the quasi-perpendicular bow shock: multi-spacecraft observations by Cluster

Large impact features on middle-sized icy satellites
Schenk, Paul M.; McKinnon, William B.; Moore, Jeffrey M. +2 more
All of the large impact features of the middle-sized icy satellites of Saturn and Uranus that were clearly observed by the Voyager spacecraft are described. New image mosaics and stereo-and-photoclinometrically-derived digital elevation models are presented. Landforms related to large impact features, such as secondary craters and possible antipod…
Differential velocity between solar wind protons and alpha particles in pressure balance structures
Sakurai, Takashi; Suess, Steven T.; Steinberg, John T. +1 more
Pressure balance structures (PBSs) are a common high-plasma beta feature in high-latitude, high-speed solar wind. They have been proposed as remnants of coronal plumes. If true, they should reflect the observation that plumes are rooted in unipolar magnetic flux concentrations in the photosphere and are heated as oppositely directed flux is advect…
