Bottom-heavy initial mass function in a nearby compact L*-galaxy
Ronald Läsker, Remco C. E. van den Bosch, Glenn van de Ven +4
We present orbit-based dynamical models and stellar population analysis of galaxy SDSS J151741.75-004217.6, a low-redshift (z=0.116) early-type galaxy (ETG) which, for its moderate…
The complex nature of the nuclear star cluster in FCC 277
Mariya Lyubenova, Remco C. E. van den Bosch, Patrick Cote +6
Recent observations have shown that compact nuclear star clusters (NSCs) are present in up to 80% of galaxies. However, detailed studies of their dynamical and chemical properties…
The VIRUS-P Exploration of Nearby Galaxies (VENGA): Survey Design, Data Processing, and Spectral Analysis Methods
Guillermo A. Blanc, Tim Weinzirl, Mimi Song +14
We present the survey design, data reduction, and spectral fitting pipeline for the VIRUS-P Exploration of Nearby Galaxies (VENGA). VENGA is an integral field spectroscopic survey,…
A Stellar Dynamical Mass Measurement of the Black Hole in NGC 3998 from Keck Adaptive Optics Observations
Jonelle L. Walsh, Remco C. E. van den Bosch, Aaron J. Barth +1
We present a new stellar dynamical mass measurement of the black hole in the nearby, S0 galaxy NGC 3998. By combining laser guide star adaptive optics observations obtained with th…
Orbit-based dynamical models of the Sculptor dSph galaxy
Maarten A. Breddels, A. Helmi, R. C. E. van den Bosch +2
We have developed spherically symmetric dynamical models of dwarf spheroidal galaxies using Schwarzschild's orbit superposition method. This type of modelling yields constraints bo…
The SAURON project-XXI. The spatially-resolved UV-line strength relations of early-type galaxies
Hyunjin Jeong, Sukyoung K. Yi, Martin Bureau +13
The unexpected rising flux of early-type galaxies at decreasing ultraviolet (UV) wavelengths is a long-standing mystery. One important observational constraint is the correlation b…
The central dark matter distribution of NGC 2976
Joshua J. Adams, Karl Gebhardt, Guillermo A. Blanc +5
We study the mass distribution in the late-type dwarf galaxy NGC 2976 through stellar kinematics obtained with the VIRUS-P integral-field spectrograph and anisotropic Jeans models…
Schwarzschild models of the Sculptor dSph galaxy
Maarten A. Breddels, Amina Helmi, R. C. E. van den Bosch +2
We have developed a spherically symmetric dynamical model of a dwarf spheroidal galaxy using the Schwarzschild method. This type of modelling yields constraints both on the total m…
The SAURON Project - XX. The Spitzer [3.6] - [4.5] colour in early-type galaxies: colours, colour gradients and inverted scaling relations
Reynier F. Peletier, Elif Kutdemir, Guido van der Wolk +15
We investigate the [3.6] - [4.5] Spitzer-IRAC colour behaviour of the early-type galaxies of the SAURON survey, a representative sample of 48 nearby ellipticals and lenticulars. We…
The SAURON Project - XIX. Optical and near-infrared scaling relations of nearby elliptical, lenticular and Sa galaxies
J. Falcón-Barroso, G. van de Ven, R. F. Peletier +16
[Abridged] We present ground-based MDM V-band and Spitzer/IRAC 3.6um-band photometric observations of the 72 representative galaxies of the SAURON Survey. In combination with the S…
The SAURON project - XVIII. The integrated UV-linestrength relations of early-type galaxies
Martin Bureau, Hyunjin Jeong, Sukyoung K. Yi +17
Using far (FUV) and near (NUV) ultraviolet photometry from guest investigator programmes on the Galaxy Evolution Explorer (GALEX) satellite, optical photometry from the MDM Observa…
The VIRUS-P Exploration of Nearby Galaxies (VENGA): Survey Design and First Results
Guillermo A. Blanc, Karl Gebhardt, Amanda Heiderman +14
VENGA is a large-scale extragalactic IFU survey, which maps the bulges, bars and large parts of the outer disks of 32 nearby normal spiral galaxies. The targets are chosen to span…
The SAURON project - XV. Modes of star formation in early-type galaxies and the evolution of the red sequence
K. L. Shapiro, J. Falcon-Barroso, G. van de Ven +15
We combine SAURON integral field data of a representative sample of local early-type, red sequence galaxies with Spitzer/IRAC imaging in order to investigate the presence of trace…
An HI view of the on-going assembly of early-type galaxies: present and future observations
P. Serra, R. Morganti, T. A. Oosterloo +24
We present a preliminary analysis of the HI properties of early-type galaxies in the ATLAS3D sample. Using WSRT data for ~100 galaxies outside the Virgo cluster and data from the A…
The SAURON project XVI: On the Sources of Ionisation for the Gas in Elliptical and Lenticular Galaxies
Marc Sarzi, Joseph C. Shields, Kevin Schawinski +16
Following our study on the incidence, morphology and kinematics of the ionised gas in early-type galaxies we now address the question of what is powering the observed nebular emiss…
Estimating Black Hole Masses in Triaxial Galaxies
Remco C. E. van den Bosch, P. Tim de Zeeuw
Most of the super massive black hole mass estimates based on stellar kinematics use the assumption that galaxies are axisymmetric oblate spheroids or spherical. Here we use fully g…
Stellar velocity profiles and line strengths out to four effective radii in the early-type galaxies NGC 3379 and NGC 821
A. Weijmans, M. Cappellari, R. Bacon +7
We use the integral-field spectrograph SAURON to measure the stellar line-of-sight velocity distribution and absorption line strengths out to four effective radii (Re) in the early…
