Sloan Digital Sky Survey Quasars in the SWIRE ELAIS N1 Field: Properties and Spectral Energy Distributions
E. Hatziminaoglou, I. Perez-Fournon, M. Polletta +16
We present a mid-infrared analysis of 35 quasars with spectroscopic redshifts selected from the Spitzer Wide-area InfraRed Extragalactic Survey (SWIRE). We discuss their optical an…

Radio imaging of core-dominated high redshift quasars
Peter D. Barthel, Marianne Vestergaard, Colin J. Lonsdale
VLA imaging at kiloparsec-scale resolution of sixteen core-dominated radio-loud QSOs is presented. Many objects appear to display variable radio emission and their radio morphologi…

A Molecular Outflow Traced by SiO Masers In Orion-KL
Sheperd Doeleman Colin Lonsdale Shannon Pelkey
We present full resolution (~0.2mas, ~0.1 A.U.) Very Long Baseline Interferometry maps of the v=1, J=1-0 SiO masers in the Orion-KL nebula. The morphology and turbulent nature of t…
