Area metric gravity and accelerating cosmology
Raffaele Punzi, Frederic P. Schuller, Mattias N. R. Wohlfarth
Area metric manifolds emerge as effective classical backgrounds in quantum string theory and quantum gauge theory, and present a true generalization of metric geometry. Here, we co…
Geometry for the accelerating universe
Raffaele Punzi, Frederic P. Schuller, Mattias N. R. Wohlfarth
The Lorentzian spacetime metric is replaced by an area metric which naturally emerges as a generalized geometry in quantum string and gauge theory. Employing the area metric curvat…
Molecular excitation in the Eagle nebula's fingers
F. Schuller, S. Leurini, C. Hieret +5
Context: The M16 nebula is a relatively nearby Hii region, powered by O stars from the open cluster NGC 6611, which borders to a Giant Molecular Cloud. Radiation from these hot sta…
APECS - The Atacama Pathfinder Experiment Control System
D. Muders, H. Hafok, F. Wyrowski +7
APECS is the distributed control system of the new Atacama Pathfinder EXperiment (APEX) telescope located on the Llano de Chajnantor at an altitude of 5107 m in the Atacama desert…
Geometric obstruction of black holes
Raffaele Punzi, Frederic P. Schuller, Mattias N. R. Wohlfarth
We study the global structure of Lorentzian manifolds with partial sectional curvature bounds. In particular, we prove completeness theorems for homogeneous and isotropic cosmologi…
Recent star formation in the inner Galactic Bulge seen by ISOGAL. I - Classification of bright mid-IR sources in a test field
F. Schuller, A. Omont, I. S. Glass +3
Context: The stellar populations in the central region of the Galaxy are poorly known because of the high visual extinction and very great source density in this direction. Aims: T…
