Testing High-Energy Emission Models for Blazars with X-ray Polarimetry
Abel L. Peirson, Ioannis Liodakis, Roger W. Romani
Both leptonic and hadronic emission processes may contribute to blazar jet emission; which dominates in blazars's high energy emission component remains an open question. Some inte…
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…
Towards Optimal Signal Extraction for Imaging X-ray Polarimetry
A. L. Peirson, R. W. Romani
We describe an optimal signal extraction process for imaging X-ray polarimetry using an ensemble of deep neural networks. The initial photo-electron angle, used to recover the pola…
The Relativistic Jet Orientation and Host Galaxy of the Peculiar Blazar PKS 1413+135
A. C. S. Readhead, V. Ravi, I. Liodakis +26
PKS 1413+135 is one of the most peculiar blazars known. Its strange properties led to the hypothesis almost four decades ago that it is gravitationally lensed by a mass concentrati…
Deep Ensemble Analysis for Imaging X-ray Polarimetry
A. L. Peirson, R. W. Romani, H. L. Marshall +2
We present a method for enhancing the sensitivity of X-ray telescopic observations with imaging polarimeters, with a focus on the gas pixel detectors (GPDs) to be flown on the Imag…
The Polarization Behavior of Relativistic Synchrotron Self-Compton Jets
A. L. Peirson, R. W. Romani
We describe a geometric model for synchrotron and synchrotron self-Compton (SSC) radiation from blazar jets, involving multiple emission zones with turbulent magnetic fields and fu…
