Steady states of the Parker instability

Devika Tharakkal, Anvar Shukurov, Frederick A. Gent +3

We study the linear properties, nonlinear saturation and a steady, strongly nonlinear state of the Parker instability in galaxies. We consider magnetic buoyancy and its consequence…

The small-scale dynamo in a multiphase supernova-driven medium

Frederick A. Gent, Mordecai-Mark Mac Low, Maarit J. Korpi-Lagg +1

Magnetic fields grow quickly, even at early cosmological times, suggesting the action of a small-scale dynamo (SSD) in the interstellar medium (ISM) of galaxies. Many studies have…

Jetted narrow-line Seyfert 1 galaxies breaking the jet paradigm -- a comprehensive study of host galaxy morphologies

Irene Varglund, Emilia Järvelä, Anne Lähteenmäki +3

Narrow-line Seyfert 1 (NLS1) galaxies are unevolved active galactic nuclei (AGN) that exist predominantly in spiral galaxies. However, mostly due to the small number of sources stu…

The evolution of the radio luminosity function of group galaxies in COSMOS

E. Vardoulaki, G. Gozaliasl, A. Finoguenov +2

[Abridged] To understand the role of the galaxy group environment on galaxy evolution, we present a study of radio luminosity functions (RLFs) of group galaxies based on the VLA-CO…

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…
