We discuss the propagation of radiative MHD jets and outflows focusing on outflows driven by magnetocentrifugal rotators. Our goal is to link the properties of the jets with the physics of the sources which produce them. We find that density and magnetic field stratification (with radius) in jets from magnetized rotators leads to new behavior including the development of a dense inner jet core ...

We show that the starburst-driven outflow in the peculiar galaxy NGC 2782 forms a well-defined collimated bubble which has an extent of ∼ 1 kpc and a closed shell at its edge, as seen in Hα, [O III], and 5 GHz radio continuum. The shell coincides with the maximum in intensity and linewidths of [O III] lines in a blueshifted emission nebula which was previously detected via optical spectroscopy ...

The central engine of gamma-ray bursts (GRBs) is believed to eject double-sided ultra-relativistic jets. For an observed GRB, one of the twin jets should point toward us, and is responsible for the prompt gamma-ray and subsequent afterglow emission. We consider in this Letter the other receding jet, which will give rise to late-time radio re-brightening (RRB) when it becomes non-relativistic (N...

We present Submillimeter Array observations toward the 10 L⊙ starforming region G240.31+0.07, in the J = 2–1 transition of CO and CO and at 1.3 mm continuum, as well as the CO and CO observations from the Caltech Submillimeter Observatory to recover the extended emission filtered out by the interferometer. Maps of the CO and CO emission show a bipolar, wide-angle, quasi-parabolic molecular outf...

Ground based imaging, imaging polarimetry, and recentHubble Space Telescope WFPC2 and NICMOS images of protostars have revealed very complex scattered light patterns that cannot be entirely explained by 2-D radiation transfer models. We present here for the first time radiation transfer models of T Tau and IRAS 04016+2610 that are fully 3-D, with the aim of investigating the effects on image mo...

Molecular outflows in the form of wide-angle winds and/or well-collimated jets are associated with young stellar objects of all luminosities. Independent studies have established that the mass outflow rate is proportional to L bol for Lbol = 0.3 to 10 5 L⊙, suggesting that there is a strong link between accretion and outflow for a wide range of source luminosity and there is reasonable evidence...

We present results from two Chandra/ACIS-I observations and one XMM-Newton observation of X-ray emission from the interstellar medium (ISM) and the inner radio lobes of the nearby radio galaxy Centaurus A. The ISM has an average radial surface brightness profile that is well described by a -model profile with index 1⁄4 0:40 0:04 and a temperature of kBTISM 0:29 keV beyond 2 kpc from the nucleus...

The black hole X-ray transient XTE J1550-564 has undergone a strong outburst in 1998 and two relativistic X-ray jets have been detected years later with the Chandra X-ray observatory; the eastern jet was found previously to have decelerated after its first detection. Here we report a full analysis of the evolution of the western jet; significant deceleration is also detected in the western side...
