Dynamical masses for the nearest brown dwarf binary: Epsilon Indi Ba, Bb
C. V. Cardoso, M. J. McCaughrean, R. R. King +6
We present preliminary astrometric results for the closest known brown dwarf binary to the Sun: Epsilon Indi Ba, Bb at a distance of 3.626 pc. Via ongoing monitoring of the relativ…
Near-infrared wavefront sensing for the VLT interferometer
Stefan Hippler, Wolfgang Brandner, Yann Clénet +11
The very large telescope (VLT) interferometer (VLTI) in its current operating state is equipped with high-order adaptive optics (MACAO) working in the visible spectrum. A low-order…
GRAVITY: getting to the event horizon of Sgr A*
F. Eisenhauer, G. Perrin, W. Brandner +45
We present the second-generation VLTI instrument GRAVITY, which currently is in the preliminary design phase. GRAVITY is specifically designed to observe highly relativistic motion…
PANIC: the new panoramic NIR camera for Calar Alto
H. Baumeister, M. Alter, M. C. Cardenas Vazquez +16
PANIC is a wide-field NIR camera, which is currently under development for the Calar Alto observatory (CAHA) in Spain. It uses a mosaic of four Hawaii-2RG detectors and covers the…
Preliminary optical design of PANIC, a wide-field infrared camera for CAHA
M. C. Cardenas, J. Rodriguez Gomez, R. Lenzen +1
In this paper, we present the preliminary optical design of PANIC (PAnoramic Near Infrared camera for Calar Alto), a wide-field infrared imager for the Calar Alto 2.2 m telescope.…
METIS - the Mid-infrared E-ELT Imager and Spectrograph
Bernhard R. Brandl, Rainer Lenzen, Eric Pantin +19
METIS, the Mid-infrared ELT Imager and Spectrograph (formerly called MIDIR), is a proposed instrument for the European Extremely Large Telescope (E-ELT), currently undergoing a pha…
