Radio jets from stellar tidal disruptions [PDF]
, 2011 A star that passes too close to a massive black hole will be torn apart by tidal forces. The flare of photons emitted during the accretion of the stellar debris is predicted to be observable, and candidates of such events have been observed at optical to

Identifying a Point-Symmetrical Morphology in the Core-Collapse Supernova Remnant W44
UniverseI identify a point-symmetrical morphology in the core-collapse supernova remnant (CCSNR) W44 compatible with shaping by three or more pairs of jets in the jittering jets explosion mechanism (JJEM). Motivated by recent identifications of point-symmetrical

MHD Simulations of AGN Jets in a Dynamic Galaxy Cluster Medium
, 2012 We present a pair of 3-d magnetohydrodynamical simulations of intermittent jets from a central active galactic nucleus (AGN) in a galaxy cluster extracted from a high resolution cosmological simulation.

Active Galactic Nucleus Jet-inflated Bubbles as Possible Origin of Odd Radio Circles
The Astrophysical JournalOdd radio circles (ORCs) are newly discovered extragalactic radio objects with an unknown origin. In this work, we carry out three-dimensional cosmic-ray (CR) magnetohydrodynamic simulations using the FLASH code and predict the radio morphology of end-on

The physics of the radio emission in the quiet side of the AGN population with the SKA [PDF]
, 2014 Despite targets of many multiwavelength campaigns, the main physical processes at work in AGN are still under debate. In particular the origin of the radio emission and the mechanisms involved are among the open questions in astrophysics.

A deep Chandra observation of the poor cluster AWM 4 - II. The role of the radio jets in enriching the intracluster medium [PDF]
, 2010 We use a Chandra observation of the poor cluster AWM 4 to map the temperature and abundance of the intracluster medium, so as to examine the influence of the central radio galaxy on its environment.
