The s process in massive stars at low metallicity. Effect of primary N14 from fast rotating stars
M. Pignatari, R. Gallino, G. Meynet +3
The goal of this paper is to analyze the impact of a primary neutron source on the s-process nucleosynthesis in massive stars at halo metallicity. Recent stellar models including r…
Evidence for recent star formation in BCGs: a correspondence between blue cores and UV excess
A. Pipino, S. Kaviraj, C. Bildfell +3
We present a joint analysis of near-ultraviolet (NUV) data from the GALEX mission and (optical) colour profiles for a sample of 7 Brightest Cluster Galaxies (BCGs) in the Canadian…
X-ray absorption in distant type II QSOs
M. Krumpe, G. Lamer, A. Corral +7
We present the results of the X-ray spectral analysis of an XMM-Newton-selected type II QSO sample with z>0.5 and 0.5-10 keV flux of 0.3-33 x 10^{-14} erg/s/cm^2. The distribution…
The ESO Large Programme First Stars
P. Bonifacio, J. Andersen, S. Andrievsky +19
In ESO period 65 (April-September 2000) the large programme 165.N-0276, led by Roger Cayrel, began making use of UVES at the Kueyen VLT telescope. Known within the Team and outside…
Spitzer imaging of the jet driving the NGC 2264 G outflow
Paula S. Teixeira, Carolyn McCoey, Michael Fich +1
We present new infrared imaging of the NGC 2264 G protostellar outflow region, obtained with the InfraRed Array Camera (IRAC) on-board the Spitzer Space Telescope. A jet in the red…
The Gemini Deep Deep Survey: VIII. When Did Early-type Galaxies Form?
Roberto G. Abraham, Preethi Nair, Patrick J. McCarthy +13
We have used the Hubble Space Telescope's Advanced Camera for Surveys (Ford et al. 2003) to measure the cumulative mass density in morphologically-selected early-type galaxies over…
The prompt to late-time multiwavelength analysis of GRB 060210
P. A. Curran, A. J. van der Horst, A. P. Beardmore +19
We present our analysis of the multiwavelength photometric & spectroscopic observations of GRB 060210 and discuss the results in the overall context of current GRB models. All avai…
Search for Giant Planets around White Dwarfs with HST, Spitzer, and VLT
S. Friedrich, H. Zinnecker, S. Correia +3
For the last three years we have performed a survey for young (<3 Gyrs) giant planets around nearby white dwarfs with HST, Spitzer, and VLT. Direct HST/NICMOS imaging of the seven…
High-resolution X-ray spectroscopy and imaging of the nuclear outflow of the starburst galaxy NGC 253
M. Bauer, W. Pietsch, G. Trinchieri +3
Aims: Using XMM-Newton data, we have aimed to study the nuclear outflow of the nearby starburst galaxy NGC 253 in X-rays with respect to its morphology and to spectral variations a…
A Time Delay for the Largest Gravitationally Lensed Quasar: SDSS J1004+4112
J. Fohlmeister, C. S. Kochanek, E. E. Falco +12
We present 426 epochs of optical monitoring data spanning 1000 days from December 2003 to June 2006 for the gravitationally lensed quasar SDSS J1004+4112. The time delay between th…
SSSPM J1444-2019: an extremely high proper motion, ultracool subdwarf
R. -D. Scholz, N. Lodieu, M. J. McCaughrean
We present the discovery of a new extreme high proper motion object (3.5 arcsec/year) which we classify as an ultracool subdwarf with [M/H] = -0.5. It has a formal spectral type of…
Simulations of spectral lines from an eccentric precessing accretion disc
S. B. Foulkes, C. A. Haswell, J. R. Murray +1
Two dimensional SPH simulations of a precessing accretion disc in a q=0.1 binary system (such as XTE J1118+480) reveal complex and continuously varying shape, kinematics, and dissi…
Young star clusters: Clues to galaxy formation and evolution
P. Anders, U. Fritze--v. Alvensleben, R. de Grijs
Young clusters are observed to form in a variety of interacting galaxies and violent starbursts, a substantial number resembling the progenitors of the well-studied globular cluste…
Young star clusters: Metallicity tracers in external galaxies
P. Anders, U. Fritze--v. Alvensleben, R. de Grijs
Star cluster formation is a major mode of star formation in the extreme conditions of interacting galaxies and violent starbursts. These newly-formed clusters are built from recycl…
