Accelerations of stars in central 2-7 arcsec from Sgr A*
A. Young, S. Gillessen, T. de Zeeuw +10
This work presents the results from extending the long-term monitoring program of stellar motions within the Galactic Center to include stars with separations of 2 - 7 arcseconds f…
The young stars in the Galactic Center
Sebastiano von Fellenberg, Stefan Gillessen, Julia Stadler +11
We present a large spectroscopic survey of the Galactic Center using the SINFONI IFU at the VLT. Combining observations of the last two decades we compile s…
On the robustness of triaxial Schwarzschild modelling: The effects of correcting the orbit mirroring
Sabine Thater, Prashin Jethwa, Behzad Tahmasebzadeh +13
In the past 15 years, the triaxial Schwarzschild orbit-superposition code by van den Bosch et al. (2008) has been widely applied to study the dynamics of galaxies. Recently, Quenne…
The Fornax3D project: discovery of ancient massive merger events in the Fornax cluster galaxies NGC 1380 and NGC 1427
Ling Zhu, Glenn van de Ven, Ryan Leaman +16
We report the discovery of ancient massive merger events in the early-type galaxies NGC 1380 and NGC 1427, members of the Fornax galaxy cluster. Both galaxies have been observed by…
MUSE observations of the counter-rotating nuclear ring in NGC 7742
Thomas P. K. Martinsson, Marc Sarzi, Johan H. Knapen +4
We present results from MUSE observations of the nearly face-on disk galaxy NGC 7742. This galaxy hosts a spectacular nuclear ring of enhanced star formation, which is unusual in t…
The ESO Spectroscopic facility
Luca Pasquini, B. Delabre, R. S. Ellis +3
We present the concept of a novel facility dedicated to massively-multiplexed spectroscopy. The telescope has a very wide field Cassegrain focus optimised for fibre feeding. With a…
Reaching New Heights in Astronomy - ESO Long Term Perspectives
Tim de Zeeuw
A comprehensive description of ESO in the current global astronomical context, and its plans for the next decade and beyond, are presented. This survey covers all aspects of the Or…
A low upper mass limit for the central black hole in the late-type galaxy NGC 4414
Sabine Thater, Davor Krajnović, Martin A. Bourne +7
We present our mass estimate of the central black hole in the isolated spiral galaxy NGC 4414. Using natural guide star adaptive optics assisted observations with the Gemini Near-I…
New telescope designs suitable for massively-multiplexed spectroscopy
L. Pasquini, B. Delabre, R. Ellis +1
We present two novel designs for a telescope suitable for massively-multiplexed spectroscopy. The first is a very wide field Cassegrain telescope optimised for fibre feeding. It pr…
Mapping the inner regions of the polar disk galaxy NGC4650A with MUSE
E. Iodice, L. Coccato, F. Combes +6
[abridged] The polar disk galaxy NGC4650A was observed during the commissioning of the MUSE at the ESO VLT to obtain the first 2D map of the velocity and velocity dispersion for bo…
A re-evaluation of the central velocity-dispersion profile in NGC 6388
Nora Lützgendorf, Karl Gebhardt, Holger Baumgardt +4
Recently, two independent groups found very different results when measuring the central velocity dispersion of the galactic globular cluster NGC 6388 with different methods. While…
Intermediate-mass black holes in globular clusters: observations and simulations
Nora Lützgendorf, Markus Kissler-Patig, Karl Gebhardt +9
The study of intermediate-mass black holes (IMBHs) is a young and promising field of research. Formed by runaway collisions of massive stars in young and dense stellar clusters, in…
The MUSE 3D view of the Hubble Deep Field South
R. Bacon, J. Brinchmann, J. Richard +35
We observed the Hubble Deep Field South with the new panoramic integral field spectrograph MUSE that we built and just commissioned at the VLT. The data cube resulting from 27 hour…
Separable triaxial potential-density pairs in MOND
L. Ciotti, H. Zhao, T. de Zeeuw
We study mass models that correspond to MOND (triaxial) potentials for which the Hamilton-Jacobi equation separates in ellipsoidal coordinates. The problem is first discussed in th…
Early-type galaxies in different environments: an HI view
Tom Oosterloo, Raffaella Morganti, Alison Crocker +8
We present an analysis of deep WSRT observations of the HI in 33 nearby early-type galaxies selected from a sample studied earlier at optical wavelengths with the SAURON integral-f…
The SAURON project - XIII. SAURON-GALEX study of early-type galaxies: the ultraviolet colour-magnitude relations and Fundamental Planes
Hyunjin Jeong, Sukyoung K. Yi, Martin Bureau +13
We present GALEX far (FUV) and near (NUV) ultraviolet imaging of 34 nearby early-type galaxies from the SAURON representative sample of 48 E/S0 galaxies, all of which have ground-b…
The stellar populations of E and S0 galaxies as seen with SAURON
H. Kuntschner, E. Emsellem, R. Bacon +9
We present selected results from integral-field spectroscopy of 48 early-type galaxies observed as part of the SAURON survey. Maps of the Hbeta, Fe5015, Mgb and Fe5270 indices in t…
The dynamical M/L-profile and distance of the globular cluster M15
Remco van den Bosch, Tim de Zeeuw, Karl Gebhardt +2
We construct orbit-based axisymmetric dynamical models for the globular cluster M15 which fit groundbased line-of-sight velocities and Hubble Space Telescope line-of-sight velociti…
A dichotomy in radio jet orientations
Gijs Verdoes Kleijn, Tim de Zeeuw
We examine the relative orientations of radio jets, central dust and stars in low-power (i.e., FR I and FR I/II) radio galaxies. We use the position angles of jet and dust to const…
