The model first introduced by Raga & Canto in which astrophysical jets are deflected on passing through an isothermal high-density region is generalized by taking into account gravitational effects on the motion of the jet as it crosses the high-density cloud. The problem is also generalized for relativistic jets in which gravitational effects induced by the cloud are neglected. Two further cases, classical and relativistic, are discussed for the cases in which the jet is deflected on passing…

Formation of internal shock waves in bent jets
We discuss the circumstances under which the bending of a jet can generate an internal shock wave. The analysis is carried out for relativistic and non-relativistic astrophysical jets. The
The jet in the radio galaxy 3C120: Jet/cloud interactions at parsec scales
The radio galaxy 3C 120 appears as one of the best sources to study the emission and propagation of relativistic jets in active galactic nuclei. Muti-wavelength multi-epoch observations suggest that
Deflection of Jets Induced by Jet-Cloud Interactions
A non--relativistic and relativistic model in which astrophysical jets are deflected on passing through an isothermal high density region is analysed. The criteria for the stability of jets due to
Internal shocks in relativistic jets with time-dependent sources
We present a ballistic description of the formation and propagation of the working surface of a relativistic jet. Using simple laws of conservation of mass and linear momentum at the working surface,
Feedback from reorienting AGN jets
Aims. We test the effects of re-orienting jets from an active galactic nucleus (AGN) on the intracluster medium in a galaxy cluster environment with short central cooling time. We investigate both
Boundary shear acceleration in the jet of MKN501
The high-resolution image of the jet of the BL Lac object MKN501 in radio shows a limbbrightened feature. An explanation of this feature as an outcome of the differential Doppler boosting of jet
A new method for extending solutions to the self-similar relativistic magnetohydrodynamic equations for black hole outflows
The paradigm in which magnetic fields play a crucial role in launching/collimating outflows in many astrophysical objects continues to gain support. However, semi-analytical models including the
Understanding the light curves of the HST-1 knot in M87 with internal relativistic shock waves along its jet
Knots or blobs observed in astrophysical jets are commonly interpreted as shock waves moving along them. Long time observations of the HST-1 knot inside the jet of the galaxy M87 have produced
Hydrodynamics associated to the X-ray light curve of A0620-00
From 1975 to 1976, an outburst was detected in the light curve of the X-ray transient A0620-00 using the Ariel V and SAS-3 experiments. In this article we model the outburst with the hydrodynamical

Abstract The relationship between observed variability time and emission region geometry is explored for the case of emission by relativistic jets.The approximate formula for the jet-frame size of


Theory of extragalactic radio sources
Powerful extragalactic radio sources comprise two extended regions containing magnetic field and synchrotron-emitting relativistic electrons, each linked by a jet to a central compact radio source
A jet-cloud interaction in 3C 34 at redshift z=0.69
We report the detection of a strong jet-cloud interaction at a distance of 120 kpc from the nucleus of the radio galaxy 3C34, which has redshift z=0.69. Hubble Space Telescope images of the radio

Ionization, shocks and evolution of the emission‐line gas of distant 3CR radio galaxies
An analysis of the kinematics and ionization state of the emission-line gas of a sample of 14 3CR radio galaxies with redshifts z∼1 is carried out. The data used for these studies, deep long-slit
