We present a detailed analysis of the spatially-resolved properties of the lensed submillimeter galaxy SMMJ14011+0252 at z=2.56, combining deep near-infrared integral-field data ob…
Mid-Infrared Diagnostics of LINERs
E. Sturm, D. Rupke, A. Contursi +12
We report results from the first mid-infrared spectroscopic study of a comprehensive sample of 33 LINERs, observed with the Spitzer Space Telescope. We compare the properties of tw…
Host dynamics and origin of Palomar-Green QSOs
K. M. Dasyra, L. J. Tacconi, R. I. Davies +7
We present host-galaxy velocity dispersions of 12 local (mainly Palomar-Green) quasi-stellar objects (QSOs) measured directly from the stellar CO absorption features in the H band.…
Star Formation and Molecular Gas in AGN
R. Davies, R. Genzel, L. Tacconi +2
We present initial results from a survey of nearby AGN using the near infrared adaptive optics integral field spectrograph SINFONI. These data enable us to probe the distribution a…
Polarimetry of near-infrared flares from Sagittarius A*
A. Eckart, R. Schoedel, L. Meyer +3
Context: We report new polarization measurements of the variable near-infrared emission of the SgrA* counterpart associated with the massive 3--4 10^6 solar masses Black Hole at th…
The rapid formation a large rotating disk galaxy three billion years after the Big Bang
R. Genzel, L. Tacconi, F. Eisenhauer +16
[Abridged] Over the past two decades observations and theoretical simulations have established a global frame-work of galaxy formation and evolution in the young Universe. Galaxies…
Dynamical properties of Ultraluminous Infrared Galaxies. II. Traces of dynamical evolution and end products of local ultraluminous mergers
K. M. Dasyra, L. J. Tacconi, R. I. Davies +8
We present results from our Very Large Telescope large program to study the dynamical evolution of local Ultraluminous Infrared Galaxies (ULIRGs) and QSOs. This paper is the second…
GRAVITY: The adaptive optics assisted, two object beam combiner for the VLTI
S. Gillessen, G. Perrin, W. Brandner +8
We present the adaptive optics assisted, near-infrared VLTI instrument - GRAVITY - for precision narrow-angle astrometry and interferometric phase referenced imaging of faint objec…
Lyman Break Galaxies Under a Microscope: The Small Scale Dynamics and Mass of an Arc in the Cluster 1E0657-56
N. P. H. Nesvadba, M. D. Lehnert, F. Eisenhauer +8
Using the near-infrared integral-field spectrograph SPIFFI on the VLT, we have studied the spatially-resolved dynamics in the z=3.2 strongly lensed galaxy 1E0657-56 ``arc+core''. T…
