北京大学科维理天文与天体物理研究所 王然课题组 阿塔卡马 大型毫米波 亚毫米波阵列 ALMA 黑洞
2017/11/13
北京大学科维理天文与天体物理研究所王然课题组主要研究红移大于5.7的远红外亮类星体的星际介质。她们首先利用IRAM 30米望远镜和詹姆斯·克拉克·麦克斯维尔望远镜(JCMT)选取红移大于5.7的远红外亮类星体,这些类星体的寄主星系中有剧烈的恒星形成活动,恒星形成率为每年几百到几千个太阳质量。她们还采用甚大天线阵(VLA)从红移是6左右的类星体中探测到了CO(2-1),这给出了寄主星系中数量级是10...

Globular clusters – dazzling agglomerations of up to a million ancient stars – are among the oldest objects in the universe. Though plentiful in and around many galaxies, newborn examples are vanishin...
Why Do Starburst Galaxies 'Burst'? ALMA Sees Super Stellar Nurseries at Heart of Sculptor Galaxy
Starburst Galaxies Burst Super Stellar Nurseries Heart of Sculptor Galaxy
2015/3/4
Starburst galaxies transmute gas into new stars at a dizzying pace – up to 1,000 times faster than typical spiral galaxies like the Milky Way. To help understand why some galaxies "burst" while others...
