Quasar Feedback Survey: Multi-phase outflows, turbulence and evidence for feedback caused by low power radio jets inclined into the galaxy disk [PDF]
, 2022 We present a study of a luminous, z=0.15, type-2 quasar (log [L([OIII])/(erg/s)]=42.8) from the Quasar Feedback Survey. It is classified as 'radio-quiet' (log [L(1.4 GHz)/(W/Hz)]=23.8); however, radio imaging reveals ~1 kpc low-power jets (log [Pjet/(erg/

MOKA3D: An innovative approach to 3D gas kinematic modelling. I. Application to AGN ionized outflows [PDF]
Astronomy & Astrophysics, 2023 Studying the feedback process of Active Galactic Nuclei (AGN) requires characterising multiple kinematical components, such as rotating gas and stellar disks, outflows, inflows, and jets. To compare the observed properties with theoretical predictions of

Young Radio Sources Expanding in Gas-Rich ISM: Using Cold Molecular Gas to Trace Their Impact [PDF]
Galaxies, 2023 We present an overview of the results obtained from the study of the resolved distribution of molecular gas around eight young (≲106yr), peaked-spectrum radio galaxies.

Modelling observable signatures of jet-ISM interaction: thermal emission and gas kinematics [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Relativistic jets are believed to have a substantial impact on the gas dynamics and evolution of the interstellar medium (ISM) of their host galaxies. In this paper, we aim to draw a link between the simulations and the observable signatures of jet-ISM

Modeling the kinematics of the decelerating jets from the black hole X-ray binary MAXI J1348$-$630 [PDF]
, 2022 Black hole low mass X-ray binaries (BH LMXBs) can launch powerful outflows in the form of discrete ejecta. Observing the entire trajectory of these ejecta allows us to model their motion with great accuracy, and this is essential for measuring their ...

Feedback from young stars, the molecular signature of shocks and outflows
EPJ Web of Conferences, 2022 Why do we study shocks ? Because they are there. Shocks are ubiquitous in the interstellar medium (ISM), where they constitute a major source of energy injection, together with photons and cosmic rays (CRs).

The impact of young radio jets traced by cold molecular gas [PDF]
Astronomical Notes - Astronomische Nachrichten, 2021 Correspondence *R. Morganti, Email: morganti@astron.nl Ranging from a few pc to hundreds of kpc in size, radio jets have, during their evolution, an impact on their gaseous environment on a large range of scales.

AGN-driven outflows and the AGN feedback efficiency in young radio galaxies [PDF]
Astronomy & Astrophysics, 2020 Active galactic nuclei (AGN) feedback operated by the expansion of radio jets can play a crucial role in driving gaseous outflows on galaxy scales. Galaxies hosting young radio AGN, whose jets are in the first phases of expansion through the surrounding ...

Pulsar-Wind Nebulae and Magnetar Outflows: Observations at Radio, X-Ray, and Gamma-Ray Wavelengths [PDF]
Space Science Reviews, 2017 We review observations of several classes of neutron-star-powered outflows: pulsar-wind nebulae (PWNe) inside shell supernova remnants (SNRs), PWNe interacting directly with interstellar medium (ISM), and magnetar-powered outflows.

Young radio jets breaking free: molecular and HI outflows in their centers [PDF]
Proceedings of the International Astronomical Union, 2018 Our view of the central regions of AGN has been enriched by the discovery of fast and massive outflows of H I and molecular gas. Here we present a brief summary of results obtained for young (and restarted) radio AGN. We find that H I outflows tend to be
