The intergalactic magnetic field within filaments should be less polluted by magnetized outflows from active galaxies than magnetic fields in clusters...
Simultaneous modelling of the stellar halo and globular cluster system of NGC 5128
An important test for models of galaxy formation lies in the metallicity distribution functions (MDFs) of spheroid stars and their globular clusters (GCs). We...
Simultaneous multi-frequency observation of the unknown redshift blazar PG 1553+113 in March-April 2008
The blazar PG 1553+113 is a well known TeV γ-ray emitter. In this paper we determine its spectral energy distribution through simultaneous multi-frequency data...
Simultaneous Multiwavelength Observation of Mkn 501 in a Low State in 2006
We present results of the multiwavelength campaign on the TeV blazar Mkn 501 performed in 2006 July, including MAGIC for the very-high-energy (VHE) γ-ray band...
Simultaneous Multiwavelength Observations of Markarian 421 During Outburst
We report on the results of two coordinated multiwavelength campaigns that focused on the blazar Markarian 421 during its 2006 and 2008 outbursts. These...
Simultaneous Multiwavelength Observations of the Blazar 1ES 1959+650 at a Low TeV Flux
We present the results from a multiwavelength campaign on the TeV blazar 1ES 1959+650, performed in 2006 May. Data from the optical, UV, soft- and hard-X-ray...
Single stellar populations in the near-infrared. II. Synthesis models
We present unresolved single stellar population synthesis models in the near-infrared (NIR) range. The extension to the NIR is important for the study of early...
Size Evolution of the Most Massive Galaxies at 1.7 < z < 3 from GOODS NICMOS Survey Imaging
We measure the sizes of 82 massive (M>=1011 Msolar) galaxies at 1.72 our results are compatible with both a leveling off, or a mild evolution in size...
Sloan Digital Sky Survey IV: Mapping the Milky Way, Nearby Galaxies, and the Distant Universe
We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic...
