metallicity of starburst galaxies in chandra deep field south (cdf-s) , at 0.5
چکیده یکی از پارامترهای اصلی در دنبال کردن تاریخچه ی تشکیل ستاره ها و تحول کهکشان ها، مطالعه ی میزان فراوانی عناصر آن ها است. در این پایان نامه برای مطالعه ی همبستگی میان فراوانی فلزی و جرم ستاره ای کهکشان ها، از داده های طیفی 89 کهکشانِ ستاره زا استفاده شده است. طیف ها توسط طیف نگار فورس2 از میدان ژرف جنوبی چاندرا گرفته شده و جابه جایی به سرخ طیف ها همه بزرگتر از نیم و کوچکتر از یک هستند. جر...
15 صفحه اولClustering of galaxies around radio quasars at 0.5z0.8
We have observed the galaxy environments around a sample of 21 radio-loud, steepspectrum quasars at 0:5 # z # 0:82; spanning several orders of magnitude in radio luminosity. The observations also include background control fields used to obtain the excess number of galaxies in each quasar field. The galaxy excess was quantified using the spatial galaxy±quasar correlation amplitude, Bgq, and an ...
متن کاملPresent - day clustering of radio galaxies
This review discusses three ways in which radio galaxies and other high-redshift objects can give us information on the nature and statistics of cosmological inhomogeneities, and how they have evolved between high redshift and the present: (1) The present-day spatial distribution and clustering of radio galaxies; (2) The evolution of radio-galaxy clustering and biased clustering at high redshif...
متن کاملStellar Populations in the Central Galaxies of Fossil Groups
It is inferred from the symmetrical and luminous X-ray emission of fossil groups that they are mature, relaxed galaxy systems. Cosmological simulations and observations focusing on their dark halo and inter-galactic medium properties confirm their early formation. Recent photometric observations suggest that, unlike the majority of non-fossil brightest group galaxies (BGGs), the central early-t...
متن کاملAGN 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...
