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…
Dissecting the Lyman Alpha Emission Halo of LAB1
A. Weijmans, R. G. Bower, J. E. Geach +4
We report observations of Lyman Alpha Blob 1 (LAB1) in the SSA 22 protocluster region (z=3.09) with the integral-field spectrograph SAURON. We increased the signal-to-noise in the…
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…
Scaling relations in early-type galaxies from integral-field stellar kinematics
M. Cappellari, N. Scott, K. Alatalo +22
We study the origin of the scaling relations of early-type galaxies (ETGs) by constructing detailed models of the stellar dynamics for the K-band selected, volume-limited ATLAS3D s…
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…
