Magnetic fields break through the solar surface in a hierarchy of magnetic elements ranging from Earth-sized sunspots down to tiny concentrations that are...
What spectra of massive B-stars can tell us about their binary and pulsational properties
Spectroscopy is a powerful tool to unravel the nature of stellar bodies. For instance, spectra can be used to derive the temperature, gravity, and chemical...
The great energy source of ultraluminous infrared galaxies (ULIRGs) may be the accreting supermassive black holes of active galactic nuclei (AGNs) or intense...
What's Wrong with Physics Today - Why the standard models are an erosion of science
The concordance model of cosmology with its constituents dark matter and dark Energy is an established description of some anomalous observations. However, a...
In mid nineteens, it was discovered that the Sun had a dipolar global magnetic field, whose temporal evolution followed the Solar Cycle. Polar regions, as well...
Witnessing the Formation of Massive, Distant Galaxies in the (Sub)Millimeter Regime
In order to understand galaxy formation it is crucial to obtain sensitive observations of the emission of dust and molecular gas both of which constrain the on...
