The X - ray jet in the merging galaxy system Markarian 266 ?
We present deep ROSAT X-ray images of the double nucleus galaxy Mrk 266 in combination with optical images and spectra. The High Resolution Imager (HRI) X-ray morphology can be divided into four components: two nuclei of the merging galaxies, a diffuse galactic component and a strong northern jet coincident with very strong optical line emission. This jet component is decoupled from the rest of...
متن کاملThe interacting Wolf - Rayet galaxy Mkn 8
We present results of narrow-band and broad-band optical CCD imaging together with intermediate-resolution spectroscopy of the Wolf-Rayet galaxy Mkn 8. Analysis of the morphology and kinematics of the object indicates that the strong star formation episode we are witnessing in Mkn 8 is the product of the interaction of two (or three) disk galaxies. The chemical abundances and abundance ratios m...
متن کاملGalaxy Transformation by Merging
Theoretical considerations and observational data support the idea that mergers were more frequent in the past. At high redshifts, violent interactions and mergers may be implicated in the origin of Lyman-break galaxies, sub-mm starbursts, and active galactic nuclei. Most stars in cluster ellipticals probably formed at redshifts z > 2, as did most of the halo and globular clusters of the Milky ...
متن کاملGalaxy Activity in Merging Binary Galaxy Clusters
We present the results of a study of galaxy activity in two merging binary clusters (A168 and A1750) using the Sloan Digital Sky Survey (SDSS) data supplemented with the data in the literature. We have investigated the merger histories of A168 and A1750 by combining the results from a two-body dynamical model and X-ray data. In A168 two subclusters appear to have passed each other and to be com...
متن کاملThe cometary blue compact dwarf galaxies Mkn 59 and Mkn 71 A clue to dwarf galaxy evolution ?
“Cometary” Blue Compact Dwarf Galaxies (iI,C BCDs) are characterized by an off–center starburst close to the end of their elongated stellar bodies. This rare phenomenon may carry some clues on how collective star formation ignites and propagates in gas–rich low–mass stellar systems. This off– center burst may be a fortuitous enhancement of the otherwise moderate star–forming activity of a dwarf...
