The Ups and Downs of the Hubble Constant
G. A. Tammann
A brief history of the determination of the Hubble constant H_0 is given. Early attempts following Lemaitre (1927) gave much too high values due to errors of the magnitude scale, M…
Dwarf elliptical galaxies in Centaurus A group: stellar populations in AM 1339-445 and AM 1343-452
M. Rejkuba, G. S. Da Costa, H. Jerjen +2
We study the red giant populations of two dE galaxies, AM 1339-445 and AM 1343-452, with the aim of investigating the number and luminosity of any upper asymptotic giant branch (AG…
Branchings in the gamma-process path revisited
T. Rauscher
The location of the (gamma,p)/(gamma,n) and (gamma,alpha)/(gamma,n) line at gamma-process temperatures is discussed, using updated reaction rates based on global Hauser-Feshbach ca…
Nucleosynthesis in Neutrino-Driven Supernovae
C. Froehlich, W. R. Hix, G. Martinez-Pinedo +5
Core collapse supernovae are the leading actor in the story of the cosmic origin of the chemical elements. Existing models, which generally assume spherical symmetry and parameteri…
Neutrino-induced nucleosynthesis of A>64 nuclei: The nu p-process
C. Fröhlich, G. Martínez-Pinedo, M. Liebendörfer +5
We present a new nucleosynthesis process, that we denote nu p-process, which occurs in supernovae (and possibly gamma-ray bursts) when strong neutrino fluxes create proton-rich eje…
Complexity on Small Scales: The Metallicity Distribution of the Carina Dwarf Spheroidal Galaxy
A. Koch, E. K. Grebel, R. F. G. Wyse +5
The Carina dwarf spheroidal (dSph) galaxy is the only galaxy of this type that shows clearly episodic star formation separated by long pauses. Here we present metallicities for 437…
Kinematic evidence for different Planetary Nebulae Populations in the elliptical galaxy NGC 4697
Niranjan Sambhus, Ortwin Gerhard, Roberto H. Mendez
We have analysed the magnitudes, kinematics and positions of a complete sample of 320 PNs in the elliptical galaxy NGC 4697. We show (i) that the PNs in NGC 4697 do not constitute…
Planetary nebulae and stellar kinematics in the flattened elliptical galaxy NGC 1344
A. M. Teodorescu, R. H. Mendez, R. P. Saglia +4
We present photometric and kinematic information obtained by measuring 197 planetary nebulae (PNs) discovered in the flattened Fornax elliptical galaxy NGC 1344 (also known as NGC…
A Catalog of Edge-on Disk Galaxies: From Galaxies with a Bulge to Superthin Galaxies
S. J. Kautsch, E. K. Grebel, F. D. Barazza +1
The formation and evolution of disk-dominated galaxies is difficult to explain, yet these objects exist. We therefore embarked on a study aimed at a better understanding of these e…
Near-Field Cosmology with Local Group Dwarf Spheroidals
Eva K. Grebel
The Local Group offers an excellent laboratory for near-field cosmology by permitting us to use the resolved stellar content of its constituent galaxies as probes of galaxy formati…
Double barred galaxies at intermediate redshifts: A feasibility study
Thorsten Lisker, Victor P. Debattista, Ignacio Ferreras +1
Despite the increasing number of studies of barred galaxies at intermediate and high redshifts, double-barred (S2B) systems have only been identified in the nearby (z<0.04) univers…
The Anisotropic Distribution of M 31 Satellite Galaxies: A Polar Great Plane of Early-Type Companions
A. Koch, E. K. Grebel
The highly anisotropic distribution and apparent alignment of the Galactic satellites in polar great planes begs the question how common such distributions are. The satellite syste…
Stellar Populations in the Local Group of Galaxies
Eva K. Grebel
The characteristics and properties of the stellar populations and evolutionary histories of Local Group galaxies are summarized and compared to predictions of cosmological models.…
The Fourth Data Release of the Sloan Digital Sky Survey
J. K. Adelman-McCarthy et al.
This paper describes the fourth data release of the Sloan Digital Sky Survey (SDSS), including all survey-quality data taken through June 2004. The data release includes five-band…
Molecular Gas in NUclei of GAlaxies (NUGA) III. The warped LINER NGC3718
M. Krips, A. Eckart, R. Neri +10
We present the first interferometric observations of CO(1-0) and CO(2-1) line emission from the warped LINER NGC3718, obtained with the IRAM PdBI. This L1.9 galaxy has a prominent…
Stellar evolution with rotation XIII: Predicted GRB rates at various Z
R. Hirschi, G. Meynet, A. Maeder
We present the evolution of rotation in models of massive single stars covering a wide range of masses and metallicities. These models reproduce very well observations during the e…
High resolution spectroscopy of bright subdwarf B stars - I. Radial velocity variables
H. Edelmann, U. Heber, M. Altmann +2
Radial velocity curves for 15 bright subdwarf B binary systems have been measured using high precision radial velocity measurements from high S/N optical high-resolution spectra. I…
The Arches Cluster - Evidence for a Truncated Mass Function?
Andrea Stolte, Wolfgang Brandner, Eva K. Grebel +2
We have analyzed high-resolution, adaptive optics (AO) HK observations of the Arches cluster obtained with NAOS/CONICA. With a spatial resolution of 84 mas, the cluster center is u…
The colours of Virgo dEs as seen by SDSS
Thorsten Lisker, Eva K. Grebel, Bruno Binggeli
A colour analysis of a carefully selected sample of over 200 Virgo cluster dEs and 8 giant ellipticals (Es) in the SDSS yields the following results: a) the nucleated dEs (dENs) fo…
