The Core-like Nature of HST-1 in the M87 Jet
polarization—galaxies: active—galaxies: individual (M87)—galaxies:jets —radio continuum: general
2011/9/28
We investigate the total flux density, spectral, polarization, and Faraday rotation variability of HST-1 in the M87 jet during the outburst from 2003 to 2007 through multi-epoch VLA observations at 8,...

Galaxies: Active – Galaxies: Individual (Mrk 509) – Galaxies: Quasars: Absorption Lines – Galaxies: Seyfert –Ultraviolet: Galaxies – X-Rays: Galaxies
2011/9/27
We present medium resolution (R~20,000) HST/COS ultraviolet spectra covering 1155-1760 A of the Seyfert 1 Mrk 509 obtained simultaneously with a Chandra/LETGS spectrum as part of a multiwavelength cam...
