Two Candidate High-redshift X-Ray Jets without Coincident Radio Jets [PDF]
Astrophysical Journal, 2020 We report the detection of extended X-ray emission from two high-redshift radio quasars. These quasars, J1405+0415 at z = 3.208 and J1610+1811 at z = 3.118, were observed in a Chandra snapshot survey selected from a complete sample of the radio-brightest

Wide-Angle-Tail (WAT) Radio Sources
Galaxies, 2023 We review the properties of Wide-Angle-Tail (WAT) radio sources. The WAT radio sources are powerful, bent radio sources typically associated with the dominant galaxy in a cluster or group.

Astronomy & Astrophysics, 2023 Context.The local radio-loud AGN population is dominated by compact sources named FR0s. These sources show features, for example the host type, the mass of the supermassive black hole (SMBH), and the multi-band nuclear characteristics, that are similar to those of FRI radio galaxies.

Radio Emission of Nearby Early-type Galaxies in the Low and Very Low Radio Luminosity Range
The Astrophysical Journal, 2023 We analyze radio continuum emission of early-type galaxies with dynamical measurements of central supermassive black hole (SMBH) masses and well-characterized large-scale environments, but regardless of the exact level of the nuclear activity.

Performance analysis of control allocation using data‐driven integral quadratic constraints
Advanced Control for Applications, Volume 4, Issue 4, December 2022., 2022 Abstract A new method is presented for evaluating the performance of a nonlinear control allocation system within a linear control loop. To that end, a worst‐case gain analysis problem is formulated that can be readily solved by means of well‐established methods from robustness analysis using integral quadratic constraints (IQCs).

Prevalence of radio jets associated with galactic outflows and feedback from quasars [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present 1–7 GHz high-resolution radio imaging (VLA and e-MERLIN) and spatially resolved ionized gas kinematics for 10 z < 0.2 type 2 ‘obscured’ quasars (log [LAGN/erg s−1] ≳ 45) with moderate radio luminosities ($\log [L_{\rm {1.4\,GHz}}$/W Hz−1] =

What Drives the Ionized Gas Outflows in Radio-Quiet AGN?
Galaxies, 2023 We review the mechanisms driving the ionized gas outflows in radio-quiet (RQ) AGN. Although it constitutes ∼90% of the AGN population, what drives these outflows in these AGNs remains an open question. High-resolution imaging and integral field unit (IFU)

Radio jets from young stellar objects [PDF]
The Astronomy and Astrophysics Review, 2018 Jets and outflows are ubiquitous in the process of formation of stars since outflow is intimately associated with accretion. Free–free (thermal) radio continuum emission in the centimeter domain is associated with these jets.

Offsets between X-Ray and Radio Components in X-Ray Jets: The AtlasX
The Astrophysical Journal Supplement Series, 2023 The X-ray emission mechanism of powerful extragalactic jets—which has important implications for their environmental impacts—is poorly understood. The X-ray/radio positional offsets in the individual features of jets provide important clues.
