The University of Michigan Centimeter-Band All Stokes Blazar Monitoring Program: Single-Dish Polarimetry as a Probe of Parsec-Scale Magnetic Fields

Margo F. Aller, Hugh D. Aller, Philip A. Hughes

The University of Michigan 26-m paraboloid was dedicated to obtaining linear polarization and total flux density observations of blazars from the mid-1960s until June 2012 providin…

Radiative Transfer Modeling of Radio-band Linear Polarization Observations as a Probe of the Physical Conditions in the Jets of Gamma-ray Flaring Blazars

Margo F. Aller, Philip A. Hughes, Hugh D. Aller +2

Since the mid-1980s the shock-in-jet model has been the preferred paradigm to explain radio-band flaring in blazar jets. We describe our radiative transfer model incorporating rela…

The Extreme Gamma-Ray Blazar S5 0716+714: Jet Conditions from Radio-Band Variability and Radiative Transfer Modeling

M. F. Aller, P. A. Hughes, H. D. Aller +4

As part of a program to identify the physical conditions in the jets of gamma-ray-flaring blazars detected by Fermi, including the role of shocks in the production of high-energy f…

Constraining the Physical Conditions in the Jets of Gamma-ray Flaring Blazars using Centimeter-Band Polarimetry and Radiative Transfer Simulations. II. Exploring Parameter Space and Implications

Philip A. Hughes, Margo F. Aller, Hugh D. Aller

We analyze the shock-in-jet models for the gamma-ray flaring blazars 0420-014, OJ 287, and 1156+295 presented in Aller et al. (2014, Paper I), quantifying how well the modeling con…

Constraints on Blazar Jet Conditions During Gamma-Ray Flaring from Radiative Transfer Modeling

Margo F. Aller, Philip A. Hughes, Hugh D. Aller +1

As part of a program to investigate jet flow conditions during GeV gamma-ray flares detected by Fermi, we are using UMRAO multi-frequency, centimeter-band total flux density and li…
