The MASIV Survey IV: relationship between intra-day scintillation and intrinsic variability of radio AGNs
J. Y. Koay, J. -P. Macquart, D. L. Jauncey +8
We investigate the relationship between 5 GHz interstellar scintillation (ISS) and 15 GHz intrinsic variability of compact, radio-selected AGNs drawn from the Microarcsecond Scinti…
Multiband Observations of the Quasar PKS 2326-502 during Active and Quiescent Gamma-Ray States in 2010-2012
Michael S. Dutka, Bryce D. Carpenter, Roopesh Ojha +12
Quasi-simultaneous observations of the Flat Spectrum Radio Quasar PKS 2326-502 were carried out in the gamma-ray, X-ray, UV, optical, near-infrared, and radio bands. Thanks to thes…
Radio follow-up of the gamma-ray flaring gravitational lens JVAS B0218+357
Cristiana Spingola, D. Dallacasa, M. Orienti +13
We present results on multifrequency Very Long Baseline Array (VLBA) monitoring observations of the double-image gravitationally lensed blazar JVAS B0218+357. Multi-epoch observati…
Very-high-energy gamma-rays from the Universe's middle age: detection of the z=0.940 blazar PKS 1441+25 with MAGIC
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +246
The flat-spectrum radio quasar PKS 1441+25 at a redshift of z = 0.940 is detected between 40 and 250 GeV with a significance of 25.5 σ using the MAGIC telescopes. Together with the…
