Detecting Obscured AGN in the Distant Universe with Spitzer
J. L. Donley, G. H. Rieke, P. G. Perez-Gonzalez +2
We present the results of a Spitzer search for obscured AGN in the Chandra Deep Field-North, using both radio-excess and mid-infrared power-law selection. AGN selected via the form…
Multiple Point-Symmetric Ejections in IC 4634
Martin A. Guerrero, Luis F. Miranda, You-Hua Chu
We present a spatio-kinematical study of the planetary nebula (PN) IC 4634 which has experienced several episodes of point-symmetric ejections oriented at different directions. The…
Radiative transfer in molecular lines
A. Asensio Ramos, J. Trujillo Bueno, J. Cernicharo
The highly convergent iterative methods developed by Trujillo Bueno and Fabiani Bendicho (1995) for radiative transfer (RT) applications are generalized to spherical symmetry with…
Evidence for Galaxy Formation at High Redshift
T. Shanks, N. Metcalfe, R. Fong +3
We have shown previously that galaxy counts from the UV to the near-IR are well-fitted by simple evolutionary models where the space density of galaxies remains constant with look-…
Production of Lithium in the Galactic Disk
E, Casuso, J. E. Beckman
We examine the evolution of Li in the Galactic disk,basing our model on the compilation of Li v.Fe observations in stars of iron abundance ranging between halo values,which give a…
The Observational Status of Stephan's Quintet
Mariano Moles, Isabel Marquez, Jack W. Sulentic
We present new photometric and spectroscopic data for the galaxies in the compact group known as Stephan's Quintet. We find the strongest evidence for dynamical perturbation in the…
