Unveiling the remarkable photodissociation region of M8
M. Tiwari, K. M. Menten, F. Wyrowski +5
Messier 8 is one of the brightest HII regions in the sky. Using SOFIA, APEX 12 m and IRAM 30 m telescopes, we have performed a comprehensive imaging survey of the emission from the…
Infall through the evolution of high-mass star-forming clumps
F. Wyrowski, R. Güsten, K. M. Menten +6
With the GREAT receiver at the Stratospheric Observatory for Infrared Astronomy (SOFIA), nine massive molecular clumps have been observed in the ammonia line at 1.…
Can we see pulsars around Sgr A*? - The latest searches with the Effelsberg telescope
R. P. Eatough, M. Kramer, B. Klein +5
Radio pulsars in relativistic binary systems are unique tools to study the curved space-time around massive compact objects. The discovery of a pulsar closely orbiting the super-ma…
GREAT confirms transient nature of the circumnuclear disk
M. A. Requena-Torres, R. Guesten, A. Weiss +6
We report SOFIA/GREAT, Herschel/HIFI, and ground-based velocity-resolved spectroscopy of carbon monoxide (CO) rotational transitions from J=2-1 to J=16-15 toward two positions in t…
High-resolution wide-band Fast Fourier Transform spectrometers
Bernd Klein, Stefan Hochgürtel, Ingo Krämer +3
We describe the performance of our latest generations of sensitive wide-band high-resolution digital Fast Fourier Transform Spectrometer (FFTS). Their design, optimized for a wide…
Terahertz ammonia absorption as a probe of infall in high-mass star forming clumps
F. Wyrowski, R. Güsten, K. M. Menten +2
Cloud contraction and infall are the fundamental processes of star formation. While "blue-skewed" line profiles observed in high- mass star forming regions are commonly taken as ev…
