We present results on the cosmic evolution of the outskirts of disk galaxies. In particular we focus on galaxies with stellar disk truncations. Using UDF, GOODS...
Cosmic evolution of stellar disk truncations: from z = 1 to the Local Universe
We present our recent results on the cosmic evolution of the outskirts of disk galaxies. In particular we focus on disk-like galaxies with stellar disk...
An extraordinary recent development in astrophysics was the discovery of the fossil relationship between central black hole mass and the stellar mass of...
Magnetic fields play an important role in many astrophysical processes. They are difficult to detect and characterize since often their properties have to be...
Cosmic Microwave Background Observations from Tenerife
This contribution reports the status of the Cosmic Microwave Background (CMB) experiments on Tenerife. These include the classic Tenerife beam-switching...
A survey is made of the evidence for and against the hypothesis that cosmic rays affect cloud cover and thereby surface temperature. The analysis is made for...
Cosmic rays and climate: The influence of cosmic rays on terrestrial clouds and global warming
We analyse the new ISCCP (International Satellite Cloud Climatology Project) D2 cloud data to ascertain if a connection between cosmic-ray flux and cloud cover...
