Scale-invariant radio jets and varying black hole spin [PDF]
, 2016 Compact radio cores associated with relativistic jets are often observed in both active galactic nuclei and X-ray binaries. Their radiative properties follow some general scaling laws which primarily depend on their masses and accretion rates.

A survey of extended radio jets with Chandra and HST
, 2004 We present the results from an X-ray and optical survey of a sample of 17 radio jets in AGN performed with Chandra and HST. The sample was selected from the radio and is unbiased toward detection at shorter wavelengths, but preferentially it includes ...

A Galactic survey of radio jets from massive protostars [PDF]
, 2021 In conjunction with a previous southern-hemisphere work, we present the largest radio survey of jets from massive protostars to date with high-resolution, ($\sim 0.04^{\prime\prime}$) VLA observations towards two subsamples of massive star-forming ...

Dynamics of relativistic radio jets in asymmetric environments [PDF]
, 2021 We have carried out relativistic three-dimensional simulations of high-power radio sources propagating into asymmetric cluster environments. We offset the environment by 0 or 1 core radii (equal to 144 kpc), and incline the jets by 0, 15, or 45◦ away ...

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

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] =

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.

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

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.

Fast-spinning Black Holes Inferred from Symmetrically Limb-brightened Radio Jets [PDF]
Astrophysical Journal, 2018 This paper theoretically investigates the relations between the structure of relativistic jets and produced synchrotron images, by using a steady, axisymmetric force-free jet model.
