Discovery of polarized line emission in SN1006
W. B. Sparks, J. E. Pringle, R. F. Carswell +2
Laming (1990) predicted that the narrow Balmer line core of the ~3000 km/s shock in the SN 1006 remnant would be significantly polarized due to electron and proton impact polarizat…
Near-infrared Hubble Space Telescope polarimetry of a complete sample of narrow-line radio galaxies
E. A. Ramírez, C. N. Tadhunter, D. Axon +5
We present an analysis of 2.05 m Hubble Space Telescope (HST) polarimetric data for a sample of 13 nearby Fanaroff-Riley type II (FRII) 3CR radio sources () that ar…
HST and Spitzer point source detection and optical extinction in powerful narrow-line radio galaxies
E. A. Ramírez, C. N. Tadhunter, D. Dicken +4
We present the analysis of infrared HST and Spitzer data for a sample of 13 FRII radio galaxies at 0.03<z<0.11 that are classified as narrow-line radio galaxies (NLRG). In the cont…
Optical Proper Motion Measurements of the M87 Jet: New Results from the Hubble Space Telescope
Eileen T. Meyer, W. B. Sparks, J. A. Biretta +5
We report new results from an HST archival program to study proper motions in the optical jet of the nearby radio galaxy M87. Using over 13 years of archival imaging, we reach accu…
The long-period Galactic Cepheid RS Puppis - II. 3D structure and mass of the nebula from VLT/FORS polarimetry
P. Kervella, A. Mérand, L. Szabados +7
The long-period Cepheid RS Pup is surrounded by a large dusty nebula reflecting the light from the central star. Due to the changing luminosity of the central source, light echoes…
An optical spectroscopic survey of the 3CR sample of radio galaxies with z<0.3. III. Completing the sample
Sara Buttiglione, Alessandro Capetti, Annalisa Celotti +4
We present optical nuclear spectra for nine 3CR radio sources obtained with the Telescopio Nazionale Galileo, that complete our spectroscopic observations of the sample up to redsh…
