Magnetism and continuum surveys working together

Autor: Matteo Murgia, Chiara Ferrari, Annalisa Bonafede, Monica Trasatti, Luigina Feretti, F. Loi, Federica Govoni, V. Vacca, Gabriele Giovannini

Publikováno v: Proceedings of The many facets of extragalactic radio surveys: towards new scientific challenges — PoS(EXTRA-RADSUR2015).

Magnetic fields are everywhere in space and their presence is believed to play a crucial role in the formation and evolution of many astrophysical objects. Despite of their importance, our knowledge about evolution, structure, and origin of magnetic

Combining survey data with single-dish observations

Autor: Federica Govoni, Matteo Murgia, Monica Trasatti, Uli Klein, Gabriele Giovannini, Annalisa Bonafede

Sky surveys represent a fundamental data source for astronomy. Radio surveys, as well as pointed observations, performed with interferometers might be affected by the so-called zero-spacing problem when observing extended sources at relatively high f

Radio Halos in future surveys in the radio continuum

Autor: Ray P. Norris, Rossella Cassano, Monica Trasatti, Gianfranco Brunetti, Huub Roettgering, Melanie Johnston-Hollitt

Giant radio halos (RH) are Mpc-scale synchrotron sources detected in a significant fraction of massive and merging galaxy clusters.Their statistical properties can be used to discriminate among various models for their origin. Theoretical predictions

A multiwavelength view of the galaxy cluster Abell 523 and its peculiar diffuse radio source

Autor: Matteo Murgia, Fabio Gastaldello, Marisa Girardi, R. Barrena, Federica Govoni, Monica Trasatti, Walter Boschin, V. Vacca, Stefano Ettori, Gabriele Giovannini

Publikováno v: NASA Astrophysics Data System

We study the structure of the galaxy cluster Abell 523 (A523) at z=0.104 using new spectroscopic data for 132 galaxies acquired at the Telescopio Nazionale Galileo, new photometric data from the Isaac Newton Telescope, and X-ray and radio data from t
