Faint polarised sources in the Lockman Hole field at 1.4 GHz
A. Berger, B. Adebahr, N. Herrera Ruiz +3
We aim to study the nature of the faint, polarised radio source population whose source composition and redshift dependence contain information about the strength, morphology, and…
CALIFA, the Calar Alto Legacy Integral Field Area survey: I. Survey presentation
S. F. Sanchez, R. C. Kennicutt, A. Gil de Paz +69
We present here the Calar Alto Legacy Integral Field Area (CALIFA) survey, which has been designed to provide a first step in this direction.We summarize the survey goals and desig…
Hot gas in Mach cones around Virgo Cluster spiral galaxies
M. Wezgowiec, B. Vollmer, M. Ehle +5
The detailed comparison between observations and simulations of ram pressure stripped spiral galaxies in the Virgo cluster has led to a three dimensional view of the galaxy orbits…
Lopsidedness in WHISP galaxies: II. Morphological lopsidedness
J. van Eymeren, E. Juette, C. J. Jog +2
The distribution of stars and gas in many galaxies is asymmetric. This so-called lopsidedness is expected to significantly affect the dynamics and evolution of the disc, including…
Lopsidedness in WHISP galaxies: I. Rotation curves and kinematic lopsidedness
J. van Eymeren, E. Juette, C. J. Jog +2
The frequently observed lopsidedness of the distribution of stars and gas in disc galaxies is still considered as a major problem in galaxy dynamics. It is even discussed as an imp…
Lopsidedness in WHISP galaxies
Eva Juette, Janine van Eymeren, Chanda Jog +2
Observations of the stellar and gaseous components in disc galaxies often reveal asymmetries in the morphological and kinematic distribution. However, the origin of this effect is…
Transport of cosmic rays in the nearby starburst galaxy NGC 253
Volker Heesen, Rainer Beck, Marita Krause +1
Radio halos require the coexistence of extra-planar cosmic rays and magnetic fields. Because cosmic rays are injected and accelerated by processes related to star formation in the…
The baryonic Tully-Fisher relation and its implication for dark matter halos
C. Trachternach, W. J. G. de Blok, S. S. McGaugh +2
The baryonic Tully-Fisher relation (BTF) is a fundamental relation between baryonic mass and maximum rotation velocity. It can be used to estimate distances, as well as to constrai…
The age of blue LSB galaxies
E. I. Vorobyov, Yu. Shchekinov, D. Bizyaev +3
(Abridged). Low metallicities, large gas-to-star mass ratios, and blue colors of most low surface brightness (LSB) galaxies imply that these systems may be younger than their high…
Non-circular motions and the cusp-core discrepancy in dwarf galaxies
J. van Eymeren, C. Trachternach, B. S. Koribalski +1
Context. The cusp-core discrepancy is one of the major problems in astrophysics. It results from comparing the observed mass distribution of galaxies with the predictions of Cold D…
