Jet interactions with a giant molecular cloud in the Galactic centre and ejection of hypervelocity stars
(2012-09-21)
The hypervelocity OB stars in the Milky Way Galaxy were ejected from the central regions some 10-100 million years ago. We argue that these stars, as well as many more abundant bound OB stars in the innermost few parsecs, ...
Jet-induced star formation in gas-rich galaxies
(2012-09-01)
Feedback from active galactic nuclei (AGN) has become a major component in simulations of galaxy evolution, in particular for massive galaxies. AGN jets have been shown to provide a large amount of energy and are capable ...
Asymmetries in extragalactic double radio sources: clues from 3D simulations of jet-disc interaction
(2011-02-11)
Observational and theoretical studies of extragalactic radio sources have suggested that an inhomogeneous environment may be responsible for observed arm-length asymmetries of jets and the properties of extended emission-line ...
Physics and fate of jet related emission line regions
(Cambridge University Press, 2010)
At redshifts above z ≳ 0.5 extragalactic jet sources are commonly associated with extended emission line regions (for a review see McCarthy 1993; Miley and De Breuck 2008). The most prominent emission line is the hydrogen ...
Very light magnetized jets on large scales - I. Evolution and magnetic fields
(2009-12-21)
Magnetic fields, which are undoubtedly present in extragalactic jets and responsible for the observed synchrotron radiation, can affect the morphology and dynamics of the jets and their interaction with the ambient cluster ...
Evolution of the ISM and Galactic Activity
(2005-02-01)
We study the effects of time-dependent mass injection and heating on the evolution of the interstellar medium (ISM) in elliptical galaxies. As the large and luminous ellipticals have supermassive black holes at their cores, ...
