Roberto Angioni - VLBI and gamma-ray studies of TANAMI radio galaxies
Toggle Cloak Cloak Fermi-LAT radio galaxies, a class of -ray emitters, provide us with a way to study AGN jets at high-energy not heavily affected by relativistic effects. Unfortunately, this also means that these sources are faint high-energy emitters, and therefore more difficult to detect, making up only 1-2% of all LAT-detected AGN. The recent implementation of the Pass8 data analysis holds some potential to expand this sample, and also to detect new AGN classes at high energies, such as young radio sources. Many of the southern radio galaxies, in particular, are also poorly studied at radio wavelengths, at milliarcsecond resolution. During my PhD I will characterize the pc-scale properties of the radio galaxies in the TANAMI VLBI monitoring program, using multi-frequency radio imaging. I will also attempt to expand the -ray radio galaxy sample by analyzing LAT Pass8 data on a sample of candidate sources, with particular focus on the young sources in the TANAMI sample. Additionally, I will study the SED of the TANAMI AGN which are not detected in -rays, to search for common properties that might explain why they are still missed by the LAT. Raniere Menezes - Gamma-ray Variability of Low-luminosity AGN
Cloak Low-luminosity AGN (LLAGNs) are the most common population of active galaxies at z = 0 and are therefore very important for our understanding of AGN physics. In this talk, we will report the results from our variability survey of LLAGNs in the northern hemisphere based on 7 years of LAT observations and Pass 8. In particular, we will present the light curves and associated results – including search for flares and periodicity – for the ten brightest LLAGNs in our sample. - Laurel Kaye
