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…
