We investigate the physics driving the cosmic star formation (SF) history using the more than 50 large, cosmological, hydrodynamical simulations that together comprise the OverWhelmingly Large Simulations project. We systematically vary the parameters of the model to determine which physical processes are dominant and which aspects of the model are

We present the results from multifrequency VLBA observations from 327MHz to 8.4GHz of the gigahertz-peaked spectrum radio source PKS1518+047 (4C04.51) aimed at studying the spectral index distribution across the source. Further multifrequency archival Very Large Array data were analysed to constrain the spectral shape of the whole source. The pc

We used Spitzer Space Telescope 3.6, 8.0, 70 and 160μm data, James Clerk Maxwell Telescope HARP-B CO J = (3-2) data, National Radio Astronomy Observatory 12 m telescope CO J = (1-0) data and Very Large Array HI data to investigate the relations among polycyclic aromatic hydrocarbons (PAHs), cold (~20K) dust, molecular gas and atomic gas within NGC

The Herschel Reference Survey is a Herschel guaranteed time key project and will be a benchmark study of dust in the nearby universe. The survey will complement a number of other Herschel key projects including large cosmological surveys that trace dust in the distant universe. We will use Herschel to produce images of a statistically-complete

This paper presents the characterization of the optical range of the ALHAMBRA photometric system, a 20 contiguous, equal-width, medium-band CCD system with wavelength coverage from 3500 Å to 9700 Å. The photometric description of the system is done by presenting the full response curve as a product of the filters, CCD, and atmospheric transmission
