Atomic T Tauri disk winds heated by ambipolar diffusion
Paulo J. V. Garcia, Sylvie Cabrit, Jonathan Ferreira +2
We summarize results on the thermal and ionization structure of self-similar, magnetically-driven, atomic disk winds heated by ambipolar diffusion. We improve upon earlier work by…
Energy implications of temperature fluctuations in photoionized plasma
L. Binette, V. Luridiana
We quantify the energy radiated through all the collisionally excited lines in a photoionized nebula which is permeated by temperature fluctuations. We assume that these correspond…
A vestige low metallicity gas shell surrounding the radio galaxy 0943-242 at z=2.92
L. Binette, J. D. Kurk, M. Villar-Martin +1
Observations are presented showing the doublet CIV 1550 absorption lines superimposed on the CIV emission in the radio galaxy 0943-242. Within the errors, the redshift of the absor…
UV rest frame spectroscopy of four high redshift (z>2) active galaxies
M. Villar-Martin, R. A. E. Fosbury, L. Binette +2
We present UV spectra of a small sample of high redshift active galaxies: the hyperluminous, gravitationally lensed system SMM J02399-0136 (z=2.8) and three powerful radio galaxies…
The nature of the extreme kinematics in the extended gas of high redshift radio galaxies
M. Villar-Martin, L. Binette, R. A. E. Fosbury
We present UV rest frame spectra of 3 powerful narrow line radio galaxies and the hyperluminous type 2 active galaxy SMM02399-0136, all at high redshift (z>2). We find high velocit…
Ca depletion and the presence of dust in large scale nebulosities in radiogalaxies (II)
M. Villar-Martin, L. Binette
We investigate here the origin of the gas observed in extended emission line regions surrounding AGNs. We use the technique of calcium depletion as a test to prove or disprove the…
