A comprehensive radio study of narrow-line Seyfert 1 galaxies
I. Varglund, E. Järvelä, M. J. Hardcastle +2
Narrow-line Seyfert 1 (NLS1) galaxies are a type of active galactic nuclei (AGN) that were originally classified as sources with little to no radio emission. Although the class is…
Spectral Energy Distribution Variability of the Blazar OJ 287 during 2009-2021
Wenwen Zuo, Alok C. Gupta, Minfeng Gu +11
Using nearly simultaneous radio, near-infrared, optical, and ultraviolet data collected since 2009, we constructed 106 spectral energy distributions (SEDs) of the blazar OJ 287. Th…
Kinematics of Parsec-Scale Jets of Gamma-Ray Bright Blazars at 43 GHz during Ten Years of the VLBA-BU-BLAZAR Program
Zachary R. Weaver, Svetlana G. Jorstad, Alan P. Marscher +7
We analyze the parsec-scale jet kinematics from 2007 June to 2018 December of a sample of -ray bright blazars monitored roughly monthly with the Very Long Baseline Array at 43 G…
New Tests of Millilensing in the Blazar PKS 1413+135
A. L. Peirson, I. Liodakis, A. C. S. Readhead +26
Symmetric Achromatic Variability (SAV) is a rare form of radio variability in blazars that has been attributed to gravitational millilensing by a ~ mass cond…
Planck intermediate results. XLV. Radio spectra of northern extragalactic radio sources
Planck Collaboration, P. A. R. Ade, N. Aghanim +202
Continuum spectra covering centimetre to submillimetre wavelengths are presented for a northern sample of 104 extragalactic radio sources, mainly active galactic nuclei, based on f…
Planck intermediate results. XLVII. Planck constraints on reionization history
Planck Collaboration, R. Adam, N. Aghanim +163
We investigate constraints on cosmic reionization extracted from the Planck cosmic microwave background (CMB) data. We combine the Planck CMB anisotropy data in temperature with th…
