Galactic Satellite Systems: Radial Distribution and Environment Dependence of Galaxy Morphology
We have studied the radial distribution of the early (E/S0) and late (S/Irr) types of satellites around bright host galaxies. We made a volume-limited sample of 4,986 satellites brighter than Mr = −18.0 associated with 2,254 hosts brighter than Mr = −19.0 from the SDSS DR5 sample. The morphology of satellites is determined by an automated morphology classifier, but the host galaxies are visuall...

نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...
The Dependence of Galaxy Morphology and Structure on Environment and Stellar Mass
From the Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5), we extract a sample of 4594 galaxies at redshifts 0.02 < z < 0.03, complete down to a stellar mass of M = 10 M⊙. We quantify their structure (Sérsic index), morphology (Sérsic index + “Bumpiness”), and local environment. We show that morphology and structure are intrinsically different galaxy properties, and we demonstrate that this...
متن کاملSatellite Ecology: The Dearth of Environment Dependence
Using the Sloan Digital Sky Survey (SDSS) galaxy group catalogue of Yang et al. (2007), we study the average colour (representing star formation history) and average concentration (representing mass assembly history) of satellite galaxies as function of (i) their stellar mass, (ii) their group mass, and (iii) their group-centric radius. We find that the colours and concentrations of satellite g...
متن کاملThe Abundance and Radial Distribution of Satellite Galaxies
Using detailed mock galaxy redshift surveys (MGRSs) we investigate the abundance and radial distribution of satellite galaxies. The mock surveys are constructed using large numerical simulations and the conditional luminosity function (CLF), and are compared against data from the Two Degree Field Galaxy Redshift Survey (2dFGRS). We use Monte Carlo Markov Chains to explore the full posterior dis...
