(Halifax, N.S. : Saint Mary's University, 2000)A series of axisymmetric, radiatively cooling variable jets was modeled with the ZEUS3D hydrodynamic code, revealing features commonly seen in outflows from Young Stellar Objects. The jet known as DG Tau B, discovered in ...
-
(Halifax, N.S. : Saint Mary's University, 2008)The standard paradigm for radio galaxies is based on high-speed plasma jets, formed in active galactic nuclei, which then penetrate into the surrounding inter-galactic medium creating giant lobes of luminous material. These ...
-
(Halifax, N.S. : Saint Mary's University, 2014)The formation of plume structures has long been a consequence of fluid modelling of extragalactic radio jets. Simulations performed to date, which have been executed with and without reflective boundary conditions along ...
-
(American Astronomical Society, 1997-08)A set of three-dimensional magnetohydrodynamical simulations of supermagnetosonic magnetized jets has been performed. The jets contain an equipartition primarily poloidal magnetic field, and the effect of jet density on ...
-
(Royal Astronomical Society and Oxford University Press, 1997)The ROSAT data from the cluster gas of Cygnus A are re-examined in light of a three-dimensional hydrodynamic simulation of a supersonic jet propagating in an isothermal King atmosphere designed to follow the observed density ...
-
(Halifax, N.S. : Saint Mary's University, 2011)In this work, I present the first simulations to investigate the formation and propagation of protostellar jets that simultaneously include the launching mechanism at < 0.1 AU and the much larger observational length scales ...
-
(Halifax, N.S. : Saint Mary's University, 2014)Multiple star systems are quite common throughout the universe, so it is of interest to know what physical process may promote and prevent the fragmentation of a collapsing gas cloud that leads to multiple star system ...
-
(Halifax, N.S. : Saint Mary's University, 2015)Most stars are observed in multiple star systems, which are thought to result from the fragmentation of a protostellar cores as they collapse. This process has been studied extensively using numerical simulations but, to ...
-
(Halifax, N.S. : Saint Mary's University, 1996)Observations of the jet in M87 and its surroundings are used to constrain hydrodynamical calculations of this object. These constraints include atmospheric profiles of the gas surrounding M87, the observed point of ...
-
(Halifax, N.S. : Saint Mary's University, 2018)Numerically simulated magnetohydrodynamical jets are not at all morphologically similar to most of those which are observed in nature. Jets in nature are actually quite morphologically similar to pure hydrodynamical ...
