星系形成

Galaxy formation

Joseph Silk, Arianna Di Cintio, Irina Dvorkin

摘要:

星系形成是宇宙学观测和理论的前沿。更好的理解对于提高我们对宇宙学参数、宇宙的内容和我们的起源的认识是至关重要的。在这些讲座打算为研究生,星系形成理论进行审查,并面临着最近的观测问题。在第一堂课中,提出了以下主题:恒星形成的考虑,包括IMF,恒星形成效率和恒星形成率,星系光度函数的起源,以及矮星系的反馈。在第二讲中,我们描述了盘和大质量球状体的形成,包括超大质量黑洞的生长,球状体中的负反馈,活动星系核与恒星形成的联系,高红移下的恒星形成率和星系中的重子分数。

英文摘要:

Galaxy formation is at the forefront of observation and theory in cosmology. An improved understanding is essential for improving our knowledge both of the cosmological parameters, of the contents of the universe, and of our origins. In these lectures intended for graduate students, galaxy formation theory is reviewed and confronted with recent observational issues. In Lecture 1, the following topics are presented: star formation considerations, including IMF, star formation efficiency and star formation rate, the origin of the galaxy luminosity function, and feedback in dwarf galaxies. In Lecture 2, we describe formation of disks and massive spheroids, including the growth of supermassive black holes, negative feedback in spheroids, the AGN-star formation connection, star formation rates at high redshift and the baryon fraction in galaxies.
