CCD photometry of the old open cluster Collinder 261 ⋆
We present UBVI photometry for the old open cluster Collinder 261. From comparison of the observed colour-magnitude diagrams with simulations based on stellar evolutionary models we derive in a self consistent way reddening, distance, and age of the cluster: E(B−V)=0.25−0.34, (m-M)0=11.7-12.0, and age=7−8 Gyr or 9−11 Gyr, depending on the adopted stellar tracks. The models in better agreement w...
متن کاملWINGS: a WIde-field Nearby Galaxy-cluster Survey. I: Optical imaging
This is the first paper of a series that will present data and scientific results from the WINGS project, a widefield, multiwavelength imaging and spectroscopic survey of galaxies in 77 nearby clusters. The sample was extracted from the ROSAT catalogs of X-Ray emitting clusters, with constraints on the redshift (0.04 < z < 0.07) and distance from the galactic plane (|b| ≥20 deg). The global goa...
متن کاملA Deep, Wide-Field Weak Lensing Survey with MEGACAM
This brief document is a response to the call for ideas for CFHT imaging surveys with MEGACAM. We have been carrying out wide eld, deep imaging at the CFHT for several years now, with the primary science goal of using weak lensing of faint galaxies to probe the dark matter distribution on a range of scales from galaxy halos through galaxy cluster scales to supercluster scales. Thus far we have ...
متن کاملBrown dwarfs and very low-mass stars in the Pleiades cluster: a deep wide-field imaging survey
We have performed a deep, wide-field imaging survey of the Pleiades cluster (Melotte 22) in the R and I-bands to search for very low-mass stars and brown dwarfs. The survey extends over ∼2.5 square degrees around the cluster’s center down to a ∼90% completeness limit of R∼23 and I∼22. We find 26 objects whose location in the (I, R-I) color–magnitude diagram is consistent with them being Pleiade...
متن کاملtranslating allusive devices:a survey of a portrait of the artist as a young man by james joyce
تلمیح یکی از عناصری است که تقریباً در همه ی متون ادبی یافت و باعث ایجاد شکاف های فرهنگی می شود. در این تحقیق به عنوان شکلی از بینامتنیت در ترجمه مورد توجه قرار می گیرد. تلاش شده است تا راهکارهای مترجمان برای ترجمه چهار نوع اسامی خاص و عبارات کلیدی تلمیحی (مذهبی، سیاسی، تاریخی و اسطوره ای) موجود در رمانِ چهره مرد هنرمند در جوانی به فارسی بررسی شود. این تحقیق مقایسه ای بر اساس راهکارهای ترجمه تلمیح...
