In fact, such traits have been observed for LSBs. ...

. Left panel: The distribution of galaxies 12.7 billion years ago. White circles represent the galaxies, and their size represents the luminosity of the galaxies. The color contour represents the density; the redder the color, the higher the density. The reddest region appears in the lower part of the figure.

Astronomers at Armagh Observatory and Cardiff University have independently discovered new mechanisms by which micro-organisms may have spread throughout the Galaxy. Scientific papers on the topic by Professor Bill Napier at Armagh, and by Dr Max Wallis and Professor Chandra Wickramasinghe at Cardiff University, will appear simultaneously in the Monthly Notices of the Royal Astronomical Society . ... Cardiff scientists Max Wallis and Chandra Wickramasinghe have identified another delivery route. ...

... arXiv.org . ... Although great progress has been made in modelling the disk with radiative transfer models able to reproduce the spectral energy distribution (SED) of Herbig Ae stars, the constraints brought by images have not been yet fully exploited. Here, we are interested in checking if these new observational imaging constraints can be accounted for by predictions based on existing models of passive centrally irradiated hydrostatic disks made to fit the SEDs of the Herbig Ae stars. ...

... The combined event list takes from the intermediate event lists all of the events (combined into a single table), the collections of CCD-specific exposure tables and Good Time Interval (GTI) tables, and the collections of node-specific bad pixel tables and rejectable pixel tables. Name collisions among tables copied in from the intermediate event lists are avoided by placing the corresponding CCD number at the eighth character of the extension name. ... table : EVENTS -- evlistcomb . ... int32 . ...

... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 4­5 Gyr than in the sparse ones. ...
