Optical polarization observations of NGC 6231: evidence for a past SN fingerprint
Carlos Feinstein, Ruben Martinez, M. Marcela Vergne +2
We present the first linear multicolor polarization observations for a sample of 35 stars in the direction of the Galactic cluster NGC 6231. We have found a complex pattern in the…
Filaments and Ionized Gas in the Vicinity of 3C 244.1
Carlos Feinstein, F. Duccio Macchetto, Andre R. Martel +1
We present results of Hubble Space Telescope observations of the radio galaxy 3C 244.1. The broadband F702W (R) and F555W (V) images (WFPC2/PC) show an elliptical galaxy and gaseou…
The highly polarized open cluster Trumpler 27
Carlos Feinstein, Gustavo Baume, Ruben Vazquez +2
We have carried out multicolor linear polarimetry (UBVRI) of the brightest stars in the area of the open cluster Trumpler 27. Our data show a high level of polarization in the stel…
The Extended Line Region of 3C 299
Carlos Feinstein, F. Duccio Macchetto, Andre R. Martel +2
We present results of HST observations of the radio galaxy 3C 299. The broad-band F702W (R) and F555W (V) images (WFPC2/PC) show an elliptical galaxy, with a comet-like structure e…
