Die Kometenmission Rosetta
Krüger, Harald
Die Rosetta-Mission ist ein Meilenstein in der Erforschung der Kometen und ihrer Entstehung. Eine der größten üerraschungen war die unregelmäßge hantelförmige Gestalt des Zielkometen 67P/Tschurjumow-Gerassimenko. Er besteht wahrscheinlich aus zwei Einzelkörpern, die durch ihre Schwerkraft aneinander gehalten werden. Seine Oberfläche ist sehr rau u…
Cassini detects interstellar dust grains

The Strategy and Implementation of the Rosetta Communication Campaign
Bauer, M.; McCaughrean, M.; Landeau-Constantin, J.
The communication campaign for Rosetta has been the biggest success in the history of European Space Agency outreach, resulting in global awareness for the agency. The mission itself is an extraordinary operational and scientific success, but communicating only the operational and scientific firsts would likely not have brought the Rosetta orbiter…
Analyzing the interstellar neutral He bulk flow parameters with IBEX-Lo
Leonard, Trevor W.
Our Sun is immersed in a local galactic environment which is composed of a warm, dilute, and partially ionized gas. Due to the Sun's motion relative to this environment, the interstellar neutral (ISN) gas flows through the heliosphere providing the opportunity to perform in-situ observations of the ISN gas from Earth's orbit. The Interstellar Boun…
Inflow Generated X-Ray Corona around Supermassive Black Holes and a Unified Model for X-Ray Emission
Cen, Renyue; Wang, Lile
Three-dimensional hydrodynamic simulations are performed, which cover the spatial domain from hundreds of Schwarzschild radii to 2 pc around the central supermassive black hole of mass {10}8{M}⊙ , with detailed radiative cooling processes. The existence of a significant amount of shock heated, high temperature (≥slant {10}
Building the analytical response in frequency domain of AC biased bolometers. Application to Planck/HFI
Montier, Ludovic; Sauvé, Alexandre
Context: Bolometers are high sensitivity detector commonly used in Infrared astronomy. The HFI instrument of the Planck satellite makes extensive use of them, but after the satellite launch two electronic related problems revealed critical. First an unexpected excess response of detectors at low optical excitation frequency for ν < 1 Hz, and se…
Refinement of Stereo Image Analysis Using Photometric Shape Recovery as AN Alternative to Bundle Adjustment
Mall, U.; Wöhler, C.; Grumpe, A. +3 more
Topographic mapping, e.g. the generation of Digital Elevation Models (DEM), is of general interest to the remote sensing community and scientific research. Commonly, photogrammetric methods, e.g. stereo image analysis methods (SIAM) or bundle adjustment methods (BAM), are applied to derive 3D information based on multiple images of an area. These …
An Historic Encounter: Reviewing the Outreach around ESA's Rosetta Mission
Lorenzen, D.
The Rosetta mission is a milestone in terms of science and public outreach. The European Space Agency and the Deutsches Zentrum für Luft- und Raumfahrt in particular did a marvellous job of sparking global public interest, driven by various events throughout the mission. In contrast, the actions of the Max Planck Society research group in charge o…
Observations of long-period oscillations of the solar active regions in the visible and UV spectral intervals
Tlatov, A. G.; Dormidontov, D. V.; Chernov, Ya. O.
The variation of intensity in spectral line wings, which was obtained from observations of the patrol telescope at the Kislovodsk Mountain Astronomical Station of the Pulkovo Observatory, Russian Academy of Science (KMAS) and the Interface Region Imaging Spectrograph (IRIS) space observatory, are considered. A series of observations lasting a few …
Spectral energy distribution, radio maps and polarization of Cygnus X-1: a lepto-hadronic model
Romero, G. E.; Vila, G. S.; Pepe, C.
The microquasar Cygnus X-1 is one of the most studied astrophysical sources. Several radiative models for the non-thermal broadband emission of Cygnus X-1 are available. For the jet emission in particular, only leptonic models have been considered despite the observational evidence of the presence of hadrons in the jets of other microquasars. In t…
