... Usually processes in the source of the signal (e.g. the nucleus of an activegalaxy) and/or observational errors introduce a random component into the series, called noise. ...
... The Physics of ActiveGalaxies, ed. G. V. Bicknell, M. A. Dopita, P.J. Quinn (San Francisco: ASP), 253 . Rawlings S. et al. 1996, MNRAS, 279, 13p . ...
... The references to the redshift presented in the 2001catalog of quasars and activegalaxies (z = 1.207) do not include observational data for this object. ...
... The problem of creating large, homogeneous and deep samples of actively star-forming low-mass galaxies is very important for several applications in studies of galaxy evolution and spatial distribution. ...
... From the results of studying at BTA of one of the nearest voids, a galaxy DDO 68 with active star formation was discovered, which is the most metal-poor galaxy of the Local Volume (12+log(O/H)=7.2, D=6 Mpc ). ...
... As well as being beautiful in their own right, the images can be overlaid with information about the stars, nebulae and galaxies within them, acting as a launchpad for further exploration and inspiration. ...
... AC---active star, AGN---active galactic nucleus, BL---BL Lac object, CG---cluster of galaxies, CV---cataclysmic variable, GAL ... 1ES0953+693: The error box also contains 0953+6917, a galaxy which may have an active nucleus. ...
