Observations of the flaring Fermi-LAT blazars and prospects in spectro-polarimetry with SALT-RSS
Britto, Richard J.; Böttcher, Markus; Marais, Johannes P.; Meintjes, Pieter J.; Van Soelen, Brian (HEASA, 2016)The Fermi Gamma-Ray Space telescope has identified 1741 active galactic nuclei during its first four years of observation (2008-2012) and detected 1145 blazars and 573 blazar candidates of uncertain type (BCUs) as listed ... -
SALT spectropolarimetry and self-consistent SED and polarization modeling of blazars
Böttcher, Markus; Schutte, Hester; Van Soelen, Brian; Britto, Richard J.; Buckley, David A.H. (MDPI, 2017)We report on recent results froma target-of-opportunity program to obtain spectropolarimetry observations with the Southern African Large Telescope (SALT) on flaring gamma-ray blazars. SALT spectropolarimetry and contemporaneous ... -
Studies of optical/gamma-ray flares of blazar 4C+01.02: recent updates from the 2016-2017 observations
Britto, Richard J.; Böttcher, Markus; Schutte, Hester; Marais, Johannes P.; Van Soelen, Brian; Fermi LAT (Sissa Medialab, 2017)The flat spectrum radio quasar 4C +01.02 became one of the brightest active galactic nuclei detected at high redshift (z = 2.1) in gamma rays when it underwent a series of outbursts during several months in 2016. We monitored ...
