Periodic Gamma-ray Modulation of the blazar PG 1553+113 Confirmed by Fermi-LAT and Multi-wavelength Observations

S. Abdollahi, L. Baldini, G. Barbiellini +98

A 2.1-year periodic oscillation of the gamma-ray flux from the blazar PG 1553+113 has previously been tentatively identified in almost 7 year of data from the Fermi Large Area Tele…

VLBI images at 327 MHz of compact steep spectrum and GHz-peaked spectrum sources from the 3C and PW samples

D. Dallacasa, M. Orienti, C. Fanti +1

We present results on global very long baseline interferometry (VLBI) observations at 327 MHz of eighteen compact steep-spectrum (CSS) and GHz-peaked spectrum (GPS) radio sources f…

Variability and parsec-scale radio structure of candidate compact symmetric objects

M. Orienti, D. Dallacasa

We report results on multi-epoch Very Large Array (VLA) and pc-scale Very Long Baseline Array (VLBA) observations of candidate compact symmetric objects (CSOs) from the faint sampl…

Radio VLBA polarization and multi-band monitoring of the high-redshift quasar S5 0836+710 during a high activity period

M. Orienti, F. D'Ammando, M. Giroletti +3

We report on results of a multi-band monitoring campaign from radio to gamma rays of the high-redshift flat spectrum radio quasar S5 0836+710 during a high activity period detected…

Flaring gamma-ray emission from high redshift blazars

M. Orienti, F. D'Ammando, M. Giroletti +4

High redshift blazars are among the most powerful objects in the Universe. Although they represent a significant fraction of the extragalactic hard X-ray sky, they are not commonly…

High resolution radio observations of gamma-ray emitting Narrow-Line Seyfert 1s

M. Orienti, F. D'Ammando, M. Giroletti

The detection by Fermi-LAT of gamma-ray emission from radio-loud Narrow-Line Seyfert 1s (NLS1s) indicates that relativistic jets do not form only in blazars and radio galaxies, but…

Young radio sources: the duty-cycle of the radio emission and prospects for gamma-ray emission

M. Orienti, D. Dallacasa, G. Giovannini +2

The evolutionary stage of a powerful radio source originated by an AGN is related to its linear size. In this context, compact symmetric objects (CSOs), which are powerful and intr…

Young radio sources: a radio-gamma perspective

M. Orienti, G. Migliori, A. Siemiginowska +1

The evolutionary stage of a powerful radio source originated by an AGN is related to its linear size. In this context, compact symmetric objects (CSOs), which are powerful and intr…
