Jet Interactions with the Hot Halos of Clusters and Galaxies
, 2007 X-ray observations of cavities and shock fronts produced by jets streaming through hot halos have significantly advanced our understanding of the energetics and dynamics of extragalactic radio sources. Radio sources at the centers of clusters have dynamical ages between ten and several hundred million years.

MAGNUM survey: Compact jets causing large turmoil in galaxies [PDF]
Astronomy & Astrophysics, 2020 Context. Outflows accelerated by active galactic nuclei (AGN) are commonly observed in the form of coherent, mildly collimated high-velocity gas directed along the AGN ionisation cones and kinetically powerful (≳1044 − 45 erg s−1) jets.

Kinematics of Parsec-scale Jets of Gamma-Ray Blazars at 43 GHz during 10 yr of the VLBA-BU-BLAZAR Program [PDF]
Astrophysical Journal Supplement Series, 2022 We analyze the parsec-scale jet kinematics from 2007 June to 2018 December of a sample of γ-ray bright blazars monitored roughly monthly with the Very Long Baseline Array (VLBA) at 43 GHz under the VLBA-BU-BLAZAR program.

THE 1.6 μm NEAR-INFRARED NUCLEI OF 3C RADIO GALAXIES: JETS, THERMAL EMISSION, OR SCATTERED LIGHT? [PDF]
, 2010 Using HST NICMOS 2 observations we have measured 1.6 μm near-infrared nuclear luminosities of 100 3CR radio galaxies with z < 0.3, by modeling and subtracting the extended emission from the host galaxy. We performed a multiwavelength statistical analysis

Relativistic Jets in Gamma-Ray-Emitting Narrow-Line Seyfert 1 Galaxies [PDF]
Galaxies, 2019 Before the launch of the Fermi Gamma-ray Space Telescope satellite only two classes of active galactic nuclei (AGN) were known to generate relativistic jets and thus to emit up to the γ -ray energy range: blazars and radio galaxies, both hosted in giant ...

Radio jets from AGNs in dwarf galaxies in the COSMOS survey: mechanical feedback out to redshift ∼3.4 [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Dwarf galaxies are thought to host the remnants of the early Universe seed black holes (BHs) and to be dominated by supernova feedback. However, recent studies suggest that BH feedback could also strongly impact their growth. We report the discovery of

Constraining the photon coupling of ultra-light dark-matter axion-like particles by polarization variations of parsec-scale jets in active galaxies [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 Dark matter may consist of axion-like particles with ultra-low masses. Two-photon interactions of these particles affect the polarization of radiation propagating through the dark matter.

Jet Feedback in Star-Forming Galaxies
Galaxies, 2023 In this paper, I review our understanding of how jet feedback works in star-forming galaxies. There are some interesting differences to radiative feedback from Active Galactic Nuclei (AGN).

Radio jets and gamma-ray emission in radio-silent narrow-line Seyfert 1 galaxies [PDF]
Astronomy & Astrophysics, 2018 We have detected six narrow-line Seyfert 1 (NLS1) galaxies at 37 GHz that were previously classified as radio silent and two that were classified as radio quiet.

Leptonic and Hadronic Radiative Processes in Supermassive-Black-Hole Jets [PDF]
Galaxies, 2020 Supermassive black holes lying in the center of galaxies can launch relativistic jets of plasma along their polar axis. The physics of black-hole jets is a very active research topic in astrophysics, owing to the fact that many questions remain open on ...
