Detection of orbital motions near the last stable circular orbit of the massive black hole SgrA*
GRAVITY Collaboration, R. Abuter, A. Amorim +57
We report the detection of continuous positional and polarization changes of the compact source SgrA* in high states ('flares') of its variable near- infrared emission with the nea…
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…
GRAVITY chromatic imaging of Eta Car's core
GRAVITY Collaboration, J. Sanchez-Bermudez, G. Weigelt +132
Eta Car is one of the most intriguing luminous blue variables in the Galaxy. Observations and models at different wavelengths suggest a central binary with a 5.54 yr period residin…
Kiloparsec Scale Properties of Star-Formation Driven Outflows at z~2.3 in the SINS/zC-SINF AO Survey
Rebecca L. Davies, Natascha M. Förster Schreiber, Hannah Übler +19
We investigate the relationship between star formation activity and outflow properties on kiloparsec scales in a sample of 28 star forming galaxies at 2-2.6, using adaptive…
Detection of the gravitational redshift in the orbit of the star S2 near the Galactic centre massive black hole
GRAVITY Collaboration, R. Abuter, A. Amorim +95
The highly elliptical, 16-year-period orbit of the star S2 around the massive black hole candidate Sgr A* is a sensitive probe of the gravitational field in the Galactic centre. Ne…
The KMOS^3D Survey: Demographics and Properties of Galactic Outflows at z = 0.6 - 2.7
N. M. Förster Schreiber, H. Übler, R. L. Davies +27
We present a census of ionized gas outflows in 599 normal galaxies at redshift 0.6<z<2.7, mostly based on integral field spectroscopy of Ha, [NII], and [SII] line emission. The sam…
A Detection of Sgr A* in the far infrared
Sebastiano D. von Fellenberg, Stefan Gillessen, Javier Graciá-Carpio +14
We report the first detection of the Galactic Centre massive black hole, Sgr~A*, in the far infrared. Our measurements were obtained with PACS on board the \emph{Herschel} satellit…
ARGOS at the LBT. Binocular laser guided ground layer adaptive optics
S. Rabien, R. Angel, L. Barl +48
Having completed its commissioning phase, the Advanced Rayleigh guided Ground-layer adaptive Optics System (ARGOS) facility is coming online for scientific observations at the Larg…
Cross-calibration of CO- vs dust-based gas masses and assessment of the dynamical mass budget in Herschel-SDSS Stripe82 galaxies
Caroline Bertemes, Stijn Wuyts, Dieter Lutz +7
We present a cross-calibration of CO- and dust-based molecular gas masses at . Our results are based on a survey with the IRAM 30-m telescope collecting CO(1-0) me…
SHINING, A Survey of Far Infrared Lines in Nearby Galaxies. II: Line-Deficit Models, AGN impact, [CII]-SFR Scaling Relations, and Mass-Metallicity Relation in (U)LIRGS
R. Herrera-Camus, E. Sturm, J. Graciá-Carpio +12
The SHINING survey (Paper I; Herrera-Camus et al. 2018) offers a great opportunity to study the properties of the ionized and neutral media of galaxies from prototypical starbursts…
SHINING, A Survey of Far Infrared Lines in Nearby Galaxies. I: Survey Description, Observational Trends, and Line Diagnostics
R. Herrera-Camus, E. Sturm, J. Graciá-Carpio +12
We use the Herschel/PACS spectrometer to study the global and spatially resolved far-infrared (FIR) fine-structure line emission in a sample of 52 galaxies that constitute the SHIN…
Optical Distortion in the NACO Imager
P. M. Plewa, S. Gillessen, M. Bauböck +11
In this research note, we present a set of distortion solutions that may be used to correct geometric optical distortion in images taken with the S13 camera of the NACO adaptive op…
What stellar orbit is needed to measure the spin of the Galactic center black hole from astrometric data?
Idel Waisberg, Jason Dexter, Stefan Gillessen +11
Astrometric and spectroscopic monitoring of individual stars orbiting the supermassive black hole in the Galactic Center offer a promising way to detect general relativistic effect…
The SINS/zC-SINF survey of z~2 galaxy kinematics: SINFONI adaptive optics-assisted data and kiloparsec-scale emission line properties
N. M. Förster Schreiber, A. Renzini, C. Mancini +29
We present the "SINS/zC-SINF AO survey" of 35 star-forming galaxies, the largest sample with deep adaptive optics-assisted (AO) near-infrared integral field spectroscopy at z~2. Th…
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…
