Gaseous galaxy halos

ME Putman, JEG Peek, MR Joung - Annual Review of …, 2012‏ - annualreviews.org
Galactic halo gas traces inflowing star-formation fuel and feedback from a galaxy's disk and
is therefore crucial to our understanding of galaxy evolution. In this review, we summarize …

Cold gas accretion in galaxies

R Sancisi, F Fraternali, T Oosterloo… - The Astronomy and …, 2008‏ - Springer
Evidence for the accretion of cold gas in galaxies has been rapidly accumulating in the past

There is a large consensus that gas in high-z galaxies is highly turbulent, because of a
combination of stellar feedback processes and gravitational instabilities driven by mergers …

A massive stellar bulge in a regularly rotating galaxy 1.2 billion years after the Big Bang

F Lelli, EM Di Teodoro, F Fraternali, AWS Man… - Science, 2021‏ - science.org
Cosmological models predict that galaxies forming in the early Universe experience a
chaotic phase of gas accretion and star formation, followed by gas ejection due to feedback …
