AGN Zoo and Classications of Active Galaxies
We review the variety of Active Galactic Nuclei (AGN) classes (so-calledAGN zoo") and classification schemes of galaxies by activity types based on their optical emission-line spectrum, as well as other parameters and other than optical wave-length ranges. A historical overview of discoveries of various types of active galaxies is given, including Seyfert galaxies, radio galaxies, QSOs, BL Lace...
متن کاملThe morphological segregation of galaxies in clusters . II . The properties of galaxies in the Coma cluster ⋆
We have looked for differences in the galaxy properties along the Hubble sequence and for the dependence of these properties on the environment, in an absolute magnitude complete sample of 187 galaxies in the Coma cluster. The morphological type of all galaxies was determined from our own high resolution data. We also compared this sample with other published complete samples of galaxies in the...
متن کاملOrientation of the disk galaxies in the Coma cluster
Theorientations of the spin vectors of 128disk galaxies (66 S0 galaxies, 62 S and Irr galaxies) in the Coma cluster have been statistically studied. With respect to the expected isotropic distribution, the distribution of the spin vectors in the Coma cluster is shown to be anisotropic, in the sense that S0 galaxies tend to have their spin vectors parallel to the cluster plane, while the spin ve...
متن کاملVERITAS Observations of the Coma Cluster of Galaxies
Clusters of galaxies are one of the few prominent classes of objects predicted to emit gamma rays not yet detected by satellites like EGRET or ground-based Imaging Atmospheric Cherenkov Telescopes (IACTs). The detection of Very High Energy (VHE, E > 100 GeV) gamma rays from galaxy clusters would provide insight into the morphology of non-thermal particles and fields in clusters. VERITAS, an arr...
متن کاملMultiaperture UBV RIzJHK Photometry of Galaxies in the Coma Cluster
We present a set of UBV RIzJHKs photometry for 745 J +H band selected objects in a 22.5 × 29.2 region centered on the core of the Coma cluster. This includes 516 galaxies and is at least 80% complete to H = 16, with a spectroscopically complete sample of 111 cluster members (nearly all with morphological classification) for H < 14.5. For each object we present total Kron (1980) magnitudes and a...
