Millimeter mapping at z~1: dust-obscured bulge building and disk growth
Erica J. Nelson, Ken-ichi Tadaki, Linda J. Tacconi +15
A randomly chosen star in today's Universe is most likely to live in a galaxy with a stellar mass between that of the Milky Way and Andromeda. Yet it remains uncertain how the stru…
Multiple Star Systems in the Orion Nebula
GRAVITY collaboration, Martina Karl, Oliver Pfuhl +133
This work presents an interferometric study of the massive-binary fraction in the Orion Trapezium Cluster with the recently comissioned GRAVITY instrument. We observe a total of 16…
The metrology system of the VLTI instrument GRAVITY
Magdalena Lippa, Stefan Gillessen, Nicolas Blind +24
The VLTI instrument GRAVITY combines the beams from four telescopes and provides phase-referenced imaging as well as precision-astrometry of order 10 microarcseconds by observing t…
Rotating starburst cores in massive galaxies at z=2.5
Ken-ichi Tadaki, Tadayuki Kodama, Erica J. Nelson +21
We present spatially resolved ALMA observations of the CO J=3-2 emission line in two massive galaxies at z=2.5 on the star-forming main sequence. Both galaxies have compact dusty s…
The GRAVITY instrument software / High-level software
Leonard Burtscher, Ekkehard Wieprecht, Thomas Ott +30
GRAVITY is the four-beam, near- infrared, AO-assisted, fringe tracking, astrometric and imaging instrument for the Very Large Telescope Interferometer (VLTI). It is requiring the d…
