Quantitative conclusions, however, vary between studies, because the amount of wind recycling is dependent on the details of the feedback model. We discuss these differences, known caveats, and ways to make progress in understanding how galaxies are fed at low redshift.作者: 商品 時間: 2025-3-23 11:23

Because of the rough alignment between the star-forming disk and this extended gaseous structure, the accreting material can be most easily detected with the combination of background quasars and integral field units (IFUs).

An Introduction to Gas Accretion onto Galaxies,primary sources of gas accretion are the intergalactic medium, satellite gas, and feedback material. There is support for each of these sources from observations and simulations, but the methods with which the fuel ultimately settles in to form stars remain murky.作者: Orthodontics 時間: 2025-3-24 14:12 作者: 思想靈活 時間: 2025-3-24 15:00 作者: filicide 時間: 2025-3-24 21:26 作者: 針葉類的樹 時間: 2025-3-25 00:11

The Effect of Galactic Feedback on Gas Accretion and Wind Recycling,However, outflows driven by supernovae and active galactic nuclei not only eject gas from galaxies, but also prevent gas from accreting in the first place. Furthermore, gas previously ejected from a galaxy can re-accrete onto (the same or a different) galaxy.
