Disentangling the Galaxy at low Galactic latitudes

M. Cignoni, M. Tosi, A. Bragaglia +2

We have used the field stars from the open cluster survey BOCCE, to study three low-latitude fields imaged with the Canada-France-Hawaii telescope (CFHT), with the aim of better un…

Constraining the nature of High Frequency Peakers. II. Polarization properties

M. Orienti, D. Dallacasa

Aims: The ``bright'' High Frequency Peakers (HFPs) sample is a mixture of blazars and intrinsically small and young radio sources. We investigate the polarimetric characteristics o…

Radio spectrum evolution and magnetic field in extreme GPS radio sources. The case of RXJ1459+3337

M. Orienti, D. Dallacasa

Aims: The knowledge of the properties of the youngest radio sources is very important in order to trace the earliest phase of the evolution of the radio emission. RXJ1459+3337, wit…

Constraining the nature of High Frequency Peakers. I. The spectral variability

M. Orienti, D. Dallacasa, C. Stanghellini

We investigate the spectral characteristics of 51 candidate High Frequency Peakers (HFPs), from the ``bright'' HFP sample, in order to determine the nature of each object, and to o…

A new comprehensive set of elemental abundances in DLAs III. Star formation histories

M. Dessauges-Zavadsky, F. Calura, J. X. Prochaska +2

We obtained comprehensive sets of elemental abundances for eleven damped Ly-alpha systems (DLAs) at z_DLA=1.7-2.5. In Paper I of this series, we showed for three DLA galaxies that…

Low-Frequency study of two clusters of galaxies: A2744 and A2219

E. Orru', M. Murgia, L. Feretti +6

Spectral index images can be used to constraint the energy spectrum of relativistic electrons and magnetic field distribution in radio halos and relics, providing useful informatio…
