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…
