VLBA images of High Frequency Peakers
M. Orienti, D. Dallacasa, S. Tinti +1
We propose a morphological classification based on the parsec scale structure of fifty-one High Frequency Peakers (HFPs) from the ``bright'' HFP sample. VLBA images at two adjacent…
Constraints on Evolutionary Properties of GHz Peaked Spectrum Galaxies
S. Tinti, G. De Zotti
We have used the available samples of Gigahertz Peaked Spectrum (GPS) galaxies to investigate their evolution properties in the framework of the ``youth'' scenario. Care was taken…
Surveys of extragalactic sources with Planck
G. De Zotti, C. Burigana, M. Negrello +5
Although the primary goal of ESA's Planck mission is to produce high resolution maps of the temperature and polarization anisotropies of the Cosmic Microwave Background (CMB), its…
High Frequency Peakers: young radio sources or flaring blazars?
S. Tinti, D. Dallacasa, G. De Zotti +2
We present new, simultaneous, multifrequency observations of 45 out of the 55 candidate High Frequency Peakers (HFP) selected by Dallacasa et al. (2000), carried out 3 to 4 years a…
High Frequency Peakers: Baby Radio Sources?
S. Tinti, D. Dallacasa, G. De Zotti +2
We present the results of second epoch simultaneous multifrequency observations of 45 sources out of the 55 in the sample of High Frequency Peakers (HFP) by Dallacasa et al. (2000)…
