A Bit Closer to the Stars: Four German Educators Experience Ongoing Research Aboard SOFIA

May 18, 2016

Dean of school is enthusiastic

In mid-May four German educator participated in a SOFIA research flight: Till Credner (Progymnasium Rosenfeld, Baden-Württemberg), Matthias Hünsch (Wichern-Schule, Hamburg), Andreas Lauer (Gymnasium Holzkirchen, Bayern) und Manuel Vogel (Gymnasium Spaichingen, Baden-Württemberg) took off on board SOFIA at 8:03 pm from Palmdale in California to experience how the close cooperation of US American and German engineers and scientists allows modern research at altitude up to about 43,000 feet (13 km). Due to the time shift between Germany and California the students could track their respective teacher‘s flight in the morning from school on https://de.flightaware.com/live/flight/NASA747.

Fireworks for birth of massive stars

November 14, 2016

SOFIA data are crucial to understand formation of massive young stars

An international scientific team led by Dr. Alessio Caratti o Garatti from the Dublin Institute for Advanced Studies (Ireland) for the first time observed and analyzed an outburst from a high-mass young stellar object that was caused by material accreting onto the star. The team combined mid-infrared and far-infrared images of SOFIA - the Stratospheric Observatory for Infrared Astronomy - with near-infrared images and spectra from other world-class observatories (Gemini Observatory, ESO/VLT, Calar Alto Observatory, and ESO/MPG) of a star named S255IR NIRS 3 (or NIRS 3 for short) that is 20 times more massive than our Sun. The University of Stuttgart coordinates the operation of the SOFIA observatory for the German partners.

SOFIA3 - The Third Power of a SOFIA PhD Exam

June 15, 2016

On June 9th 2016 three PhD exams were administered at the University of Stuttgart DSI (German SOFIA Institute) to Prashant Kaswekar, Enrico Pfüller, and Manuel Wiedemann, who defended their PhD theses with excellent presentations and exam performances. The special situation here was that, in unique ways, their studies all dealt with the question of how to optimize the image stability of the SOFIA telescope. During observations the SOFIA telescope is exposed to various disturbing factors such as vibrations of the aircraft, wind loads, and temperature fluctuations. In order to satisfy the needs of the scientists using the telescope, its pointing accuracy must be 0.2 arcsec or better. That tiny angle is equal to the apparent size of a penny viewed at a distance of 16 kilometers.

SOFIA ist bereit für die diesjährige Beobachtungskampagne in Neuseeland

June 8, 2016

Spektrometer der Universität Stuttgart das erste Mal Down Under

Am Montag, den 6. Juni ist SOFIA um 11:35 Ortszeit in Christchurch, Neuseeland gelandet, um in den nächsten acht Wochen in 25 Flügen den Südhimmel zu beobachten. Bereits am Samstag, den 4. Juni ist SOFIA in Palmdale, Kalifornien gestartet und mit einem Zwischenstopp in Honolulu nach Christchurch, Neuseeland geflogen. Auf dem dortiegen Stützpunkt der amerikanischen National Science Foundation für ihr Antarktis-Programmwird SOFIA bis zum 25. Juli stationiert sein. Das Ferninfrarot Spektrometer FIFI-LS (Field-Imaging Far-Infrared Line Spectrometer) der Universität Stuttgart ist in diesem Jahr das erste Mal in Down Under dabei, während das deutsche Ferninfrarotspektrometer GREAT (German Receiver for Astronomy at Terahertz Frequencies) bereits zum drittem Mal in Christchurch zum Einsatz kommt. Das US-amerikanische Instrument FORCAST (Faint Object InfraRedCAmera for the SOFIA Telescope) kommt nach 2015 das zweite Mal bei einer Neuseelandkampagne zum Zug. Während des Fluges auf die Südhalbkugel waren FIFI-LS und FORCAST in speziellen Transportvorrichtungen im Rumpf der Boeing 747SP verstaut. GREAT war bereits bei den letzten Forschungsflügen im Mai von Palmdale aus am Instrumentenflansch des Teleskops montiert wird auch die ersten Beobachtungen in Neuseeland durchführen.
