In the past five years, deep imaging campaigns conducted with the Hubble Space Telescope (HST) and ground-based observatories have delivered large samples of galaxies at 6.5 6 UV-selected galaxies are relatively compact with blue UV continuum slopes, low stellar masses, and large specific star formation rates. In the last year, ALMA (the Atacama Large Millimeter Array) and ground-based infrared spectrographs have begun to complement this picture, revealing minimal dust obscuration and hard radiation fields, and prov...

大爆炸后最初十亿年的星系

在过去五年中，哈勃太空望远镜 (HST) 和地面天文台进行的深度成像活动已经在 6.5 6 个紫外线选择的星系中提供了大量星系样本，这些星系相对紧凑，具有蓝色紫外线连续谱斜率、低恒星质量和大的特定恒星形成率。去年，ALMA（阿塔卡马大型毫米波阵列）和地面红外光谱仪开始补充这张图片，揭示了最小的尘埃遮挡和硬辐射场，并证明了...
