Beginning of ReadMe : J/ApJ/639/37 AGN Seyfert galaxies and close neighbors (Koulouridis+, 2006) ================================================================================ Local and large-scale environment of Seyfert galaxies. Koulouridis E., Plionis M., Chavushyan V., Dultzin-Hacyan D., Krongold Y., Goudis C. <Astrophys. J., 639, 37-45 (2006)> =2006ApJ...639...37K ================================================================================ ADC_Keywords: Active gal. nuclei ; Galaxies, Seyfert ; Redshifts Keywords: galaxies: active - galaxies: Seyfert - large-scale structure of universe Abstract: We present a three-dimensional study of the local (<=100h^-1^kpc) and the large-scale (<=1h^-1^Mpc) environment of the two main types of Seyfert AGN galaxies. For this purpose we use 48 Seyfert 1 galaxies (with redshifts in the range 0.007<=z<=0.036) and 56 Seyfert 2 galaxies (with 0.004<=z<=0.020), located at high galactic latitudes, as well as two control samples of nonactive galaxies having the same morphological, redshift, and diameter size distributions as the corresponding Seyfert samples.
