A Keck Spectroscopic Survey of Ms 1054–03 (z = 0.83): Forming the Red Sequence
Using a magnitude-limited, spectroscopic survey of the X-ray luminous galaxy cluster MS 1054–03, we isolate 153 cluster galaxies and measure MS1054’s redshift and velocity dispersion to be z = 0.8307± 0.0004 and σz = 1156 ± 82 km s . The absorption-line, post-starburst (“E+A”), and emission-line galaxies respectively make up 63±7%, 15±4%, and 23±4% of the cluster population. With photometry fro...

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
Hst Photometry and Keck Spectroscopy of the Rich Cluster Ms 1054 – 03 : Morphologies
We present a study of 81 I-band selected, spectroscopically-confirmed members of the X-ray cluster MS 1054−03 at z = 0.83. Redshifts and spectral types were determined from Keck spectroscopy. Morphologies and accurate colors were determined from a large mosaic of HST WFPC2 images in RF606W and IF814W , corresponding to U and B in the restframe. Early-type galaxies constitute only 44 % of this g...
متن کاملThe North Ecliptic Pole Wide survey of AKARI: a near- and mid-infrared source catalog⋆
We present a photometric catalog of infrared (IR) sources based on the North Ecliptic Pole Wide field (NEP-Wide) survey of AKARI, which is an infrared space telescope launched by Japan. The NEP-Wide survey covered 5.4 deg2 area, a nearly circular shape centered on the NEP, using nine photometric filter-bands from 2−25 μm of the Infrared Camera (IRC). Extensive efforts were made to reduce possib...
متن کاملThe Chandra Deep Field-south Survey: 2 Ms Source Catalogs
We present point-source catalogs for the ≈ 2 Ms exposure of the Chandra Deep Field-South (CDF-S); this is one of the two most-sensitive X-ray surveys ever performed. The survey covers an area of ≈ 436 arcmin2 and reaches on-axis sensitivity limits of ≈ 1.9× 10−17 and ≈ 1.3× 10−16 ergs cm−2 s−1 for the 0.5–2.0 and 2–8 keV bands, respectively. Four hundred and sixty-two X-ray point sources are de...
