A surprising consistency between the far-infrared galaxy luminosity functions of the field and Coma
Ibar, E.; Peletier, R. F.; Dunne, L. +14 more
We present new deep images of the Coma Cluster from the ESA Herschel Space Observatory at wavelengths of 70, 100 and 160 µm, covering an area of 1.75 × 1.0 square degrees encompassing the core and south-west infall region. Our data display an excess of sources at flux densities above 100 mJy compared to blank-field surveys, as expected. We u…
Saturn chorus latitudinal variations
Gurnett, D. A.; Hospodarsky, G. B.; Menietti, J. D. +1 more
The variation of propagation properties of whistler mode chorus as a function of latitude is not well known at Saturn but is important for the calculation of pitch angle diffusion and nonlinear growth of chorus. The Cassini spacecraft has spent a portion of its orbital time in high-inclination orbits, allowing traversal of the magnetic equator at …
Analyzing a Block of HRSC Image Strips for a Simultaneous Bundle Adjustment
Bostelmann, J.; Heipke, C.
10 years ago the first European interplanetary mission Mars Express was launched and sent into orbit around Mars. One of the scientific instruments on board the orbiter is the High Resolution Stereo Camera (HRSC). This multi-line sensor with five panchromatic and four multispectral CCD lines was developed by the German Aerospace Center (DLR) for p…
Analysis of double-step response to an interplanetary shock in the dayside magnetosphere
Kilpua, E. K. J.; Koskinen, H. E. J.; Juusola, L. +1 more
We present an analysis of double-step magnetic field enhancement caused by interplanetary (IP) shock impacts on the Earth's magnetosphere. The structures were observed by the GOES-8, 10, 11, and 12 spacecraft in the dayside geostationary orbit, particularly during northward interplanetary magnetic field (IMF) conditions. The double-step structures…
A detailed numerical analysis of asymmetrical density distribution in Saturn's F ring during an encounter with Prometheus
Sutton, Phil J.; Kusmartsev, Feo V.
Saturn's rings, reminiscent of an early Solar system present a unique opportunity to investigate experimentally some mechanisms thought to be responsible for planet and planetesimal formation in protoplanetary discs. Here, we extended the comparison of our numerical models of Prometheus encountering the F ring employing non-interacting and interac…
Investigation of star formation toward the Sharpless 155 H II region
Fan, Zhou; Li, Jin-Zeng; Huang, Ya-Fang +1 more
We present a comprehensive study of star formation toward the H II region Sharpless 155 (S155). Star-formation activities therein were investigated based on multi-wavelength data from optical to the far-infrared. The surface density distribution of selected 2MASS sources toward S155 indicates the existence of a compact cluster, which is spatially …

Creation of 2-5 keV and 5-10 keV sky maps using XMM-Newton data
Savchenko, D. O.; Iakubovskyi, D. A.
Sky maps are powerful visualisation tools for quicklook analysis of extended sources. The latest sky map in soft X-rays (0.1-2.4 keV) has been created in the 1990's using ROSAT data. By analysing publically available data from XMM-Newton X-ray mission we constructed new sky maps in two energy bands - 2-5 keV and 5-10 keV, complementary to ROSAT da…
Comet craft ready to wake
Gibney, Elizabeth
Stakes high as European Space Agency waits for Rosetta orbiter to come out of hibernation.
Star forming regions linked to RCW 78 and the discovery of a new IR bubble
Rubio, M.; Firpo, V.; Cappa, C. E. +2 more
Aims: With the aim of investigating the presence of molecular and dust clumps linked to two star forming regions identified in the expanding molecular envelope of the stellar wind bubble RCW 78, we analyzed the distribution of the molecular gas and cold dust.
Methods: To accomplish this study we performed dust continuum observations at 8…
