the final data from SDSS-III, including the first spectra of the Multi-object APO Radial Velocity Exoplanet Large-area Survey (MARVELS), additional data from the APO Galactic Evolution Experiment (APOGEE), as well as additional sky coverage and better galaxy parameter estimates from BOSS. All...
1、BOSS系统中所有BOSS。2、上古妖王。3、每周活动：押镖活动。每张卡只能使用1次（卡片自动扣除）。你要是会员的话这个就没用了，那个是道具套餐卡 使用后可以让玩家得到30天仙籍的神奇卡片，普通玩家使用道具套餐卡后，可以享受有效时间为30天（正常时间）的道具套餐服务。如果玩家已有道具套餐功能，使...
SDSS光谱初步..特别说明:由于楼主年级过低,对天文光谱学只是略知一二,所以此处只贴出我凭借在星系动物园的经验自己总结的方法。本帖所用光谱多来自SDSS BOSS/LEGACY另本帖一天一更。*SDSS光谱上方会附上自
We present the first high-significance detection (4.1σ) of the Baryon Acoustic Oscillations (BAO) feature in the galaxy bispectrum of the twelfth data release (DR12) of the Baryon Oscillation Spectroscopic Survey (BOSS) constant mass sample (0.43 ≤ z ≤ 0.7). We measured the scale dilation...
为达成此一目的,第三代史隆数位巡天 (SDSS-III)的重子振荡光谱巡天计划 (BOSS),已完成量测60亿光年 (红移0.7)之内,重复出现的星系密度之微小增加现象;当时宇宙的年龄大约是现行的一半。这种密度涟漪称重子声学振荡 (BAOs),而且预期应以某一特定的大小出现在初期宇宙中。重子振荡光谱巡天所量测的涟漪尺度指出,...
DR17主站上会介绍其scope就是它巡天的范围，比方说截止至DR16的Extragalactic项目（BOSS，eBOSS）光谱巡天...
We study the redshift evolution of the dynamical properties of ~180, 000 massive galaxies from SDSS-III/BOSS combined with a local early-type galaxy sample from SDSS-II in the redshift range 0.1 <= z <= 0.6. The typical stellar mass of this sample is M ~2 脳 10M . We analyze ...
