Other than its large physical size, star formation in N159 appears to be indistinguishable from star formation in the Milky Way.
Our model calculations show that for an individual Milky Way-type galaxy, a better description of the local star formation is the M-KS law.
This suggests a very short formation time scale for the bulk of the stars in this galaxy.
We also show that the surface star formation rate profile of the Milky Way correlates well with the molecular gas surface density profile.
This strongly suggests that star formation in the Milky Way is a dynamic process on GMC scales.
We show evidence that the two main scenarios for the bulge formation co-exist within the Milky Way bulge.

5 answers
Active Galactic Nuclei (AGN) encompass a diverse array of energetic astrophysical sources fueled by supermassive black hole accretion in galaxies, exhibiting a broad range of observational characteristics across the electromagnetic spectrum. The AGN classification system, often likened to a complex "zoo," primarily reflects variations in a few astrophysical parameters and selection methods rather than intrinsic differences. These phenomena, prevalent in galaxies at high redshifts, present unique features not typical in regular galaxies, with intriguing physics and a rich variety of observed behaviors. AGN types include QSOs, Seyfert galaxies, BL Lac objects, and those with notable star formation, studied extensively through optical and infrared photometry to unveil emission mechanisms and circumnuclear structures. The study of AGN offers insights into the fundamental architecture of these systems, unification models, and avenues for future observational and theoretical advancements.
How does feedback affect galaxy formation and evolution?
5 answers
Feedback mechanisms, such as kinetic feedback from supernovae and AGN winds, significantly influence galaxy formation and evolution. Strong feedback reduces stellar mass in galaxies, aligning the stellar-mass-halo-mass relation with abundance matching results. It also impacts the morphology of low-mass galaxies, making them more elongated. Feedback processes regulate star formation, with AGN winds enhancing star formation in surrounding rings. The interplay between AGN wind power, star formation rate, and feedback phases shapes outflows and affects the efficiency of mass transport. Additionally, the relative contributions of black hole feedback and stellar feedback vary with galaxy mass, influencing the quenching or star-forming nature of galaxies. Overall, feedback mechanisms play a crucial role in shaping the properties and evolution of galaxies by impacting star formation, morphology, and mass transport.
What are the current theories on the milky sea phenomenon?
