Dark matter and the Tully-Fisher relations of spiral and S0 galaxies
Michael J. Williams, Martin Bureau, Michele Cappellari
We construct mass models of 28 S0-Sb galaxies. The models have an axisymmetric stellar component and a NFW dark halo and are constrained by observed Ks-band photometry and stellar…
Rest-frame ultraviolet spectrum of the gravitationally lensed galaxy `the 8 o'clock arc': stellar and interstellar medium properties

We present the first detailed analysis of the rest-frame UV spectrum of the gravitationally lensed Lyman break galaxy (LBG), the `8 o'clock arc'. The spectrum of the 8 o'clock arc…
Ly-alpha emitters in the GOODS-S field: a powerful pure nebular SED with N IV] emission at z=5.563
Anna Raiter, Robert A. E. Fosbury, Hossein Teimoorinia
[abridged] From a sample of Ly-alpha emitters in the GOODS-S field with uncontaminated photometry and optical (red) spectroscopy, we select a spatially compact object at a redshift…
Abundance analysis of a sample of evolved stars in the outskirts of Omega Centauri
Sandro Villanova, Giovanni Carraro, Riccardo Scarpa +1
The globular cluster Centauri (NGC 5139) is a puzzling stellar system harboring several distinct stellar populations whose origin still represents a unique astrophysical challe…
The X-ray to optical-UV luminosity ratio of X-ray selected Type 1 AGN in XMM-COSMOS
E. Lusso, A. Comastri, C. Vignali +29
We present a study of the X-ray to optical properties of a sample of 545 X-ray selected Type 1 AGN, from the XMM-COSMOS survey, over a wide range of redshifts ($0.04<\z<4.25$) and…
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…
Ly-alpha emitters: blue dwarfs or supermassive ULIRGs? Evidence for a transition with redshift
Kim K. Nilsson, Palle Moeller
The traditional view that Ly-alpha emission and dust should be mutually exclusive has been questioned more and more often; most notably, the observations of Ly-alpha emission from…
The nature of the recent extreme outburst of the Herbig Be/FU Ori binary Z CMa
T. Szeifert, S. Hubrig, M. Schöller +3
Z CMa is a binary system which consists of two young stars: A Herbig AeBe component "Z CMa NW" embedded in a dust cocoon and a less massive component "Z CMa SE", which is classifie…
First disk-resolved spectroscopy of (4) Vesta
Benoît Carry, Pierre Vernazza, Christophe Dumas +1
Vesta, the second largest Main Belt asteroid, will be the first to be explored in 2011 by NASA's Dawn mission. It is a dry, likely differentiated body with spectrum suggesting that…
Physical Properties of (2) Pallas
Benoit Carry, Christophe Dumas, Mikko Kaasalainen +8
We acquired and analyzed adaptive-optics imaging observations of asteroid (2) Pallas from Keck II and the Very Large Telescope taken during four Pallas oppositions between 2003 and…
Dust Properties of Protoplanetary Disks in the Taurus-Auriga Star Forming Region from Millimeter Wavelengths
L. Ricci, L. Testi, A. Natta +3
We present the most sensitive 3 mm-survey to date of protoplanetary disks carried in the Taurus-Auriga star forming region (average rms of about 0.3 mJy), using the IRAM PdBI. With…
The radius and effective temperature of the binary Ap star beta CrB from CHARA/FLUOR and VLT/NACO observations
H. Bruntt, P. Kervella, A. Merand +14
The prospects for using asteroseismology of rapidly oscillating Ap (roAp) stars are hampered by the large uncertainty in fundamental stellar parameters. Results in the literature f…
