WebbGalaxies grow through mergers with other galaxies. Astronomers can uncover evidence of this in our galaxy by mapping the motions of stars. Using the Dark Energy Spectroscopic Instrument (DESI) on the Nicholas U. Mayall Telescope at Kitt Peak National Observatory, astronomers have studied the merger history of the Andromeda Galaxy for the first time. … WebbThe classification of Stars (Atlas of the Universe).This system is referred to as the Morgan Keenan system.The Morgan-Keenan (MK) system is used in modern astronomy a classification system to organize stars according to their spectral type and luminosity class. The system was introduced by William Wilson Morgan and Philip C Keenan in 1943.

WebbHowever, Tacconi & Young (1985) suggest that irregular galaxies form stars more efficiently than do spirals and, as a consequence, that the present star formation rate of NGC 3738cannot be sustained for more than 10 8 yr. The UV spectrum resembles those of H II regions (cf. Rosa et al. 1984) with emission dominated by massive, hot stars. WebbOur knowledge about star-forming galaxies at these epochs has dramatically advanced from increasingly complete population censuses and detailed views of individual …

WebbGalaxy spectra also clearly show you whether a galaxy contains star-forming regions called HII regions. HII is a spectral emission line that corresponds to ionized hydrogen – a hydrogen atom that has lost its electron. HII regions are areas of a galaxy where hydrogen nuclei and electrons are recombining to form neutral hydrogen. the place bogorWebbGalaxy-scale outflows of gas, or galactic winds (GWs), driven by energy from star formation are a pivotal mechanism for regulation of star formation in the current model of galaxy evolution.
