VLA-COSMOS 3 GHz Large Project

Dan PMF-a: Svečana sjednica Fakultetskog vijeća održat će se u petak, 20. travnja u 11:00 sati (A1)


The VLA COSMOS 3 GHz Large Project is a survey of the COSMOS field with the Jansky VLA at 3 GHz (10 cm). Deep Jansky VLA observations to cover the entire 2 square degree COSMOS field at this frequency down to an rms of ~2 μJy/beam, uniform across the field, have been awarded (PI: Smolcic). These observations - constraining the deepest radio levels ever over a large field with superb multi-wavelength coverage - will open a range of new exploration windows in observational cosmology, and serve as the basis for next generation radio facilities, such as the Square Kilometre Array.
