Since the Hubble sequence is entirely based upon visual morphological type (shape), it may miss certain important characteristics of galaxies such as star formation rate in starburst galaxies and activity in the discriminates among other galaxy properties: • There is a correlation between Hubble type and age of the dominant population of stars, the HI content and the environment in which these galaxies are found. • Early type galaxies: (E and S0) ~ 20% of all field galaxies. – no current star formation. – redder (implying older stars). 22 Feb 2013 Grebel: Star Formation in Different Galaxy Types. 0.

Bridging the Gap between Milky Way and Distant Galaxies. 22.02.2013. 12 Apr 2013 define the various galaxy classification schemes used today (e.g., Sandage &. Bedke 1994; Buta et al. 2007), because this will allow us to establish the relationships, if any, between different galaxy types. Physical interpretations of galaxy morphology have revolved around two different domains: (1). galaxysort.pdf. • The activity also lists web sites where you can assemble different sets of galaxy images. • At the end of the activity, students may ask you for the right answer. This is a good opportunity to explain that in science, there is no great authority that gives scien- tists “the right answer." The only way to know if you are. !type. 13. Spirals and Gas. • The ISM of spiral galaxies is quite complex and show wide variations with position. • However there are certain trends - the lower the mass and the 'bluer' the galaxy the higher is the baryonic fraction in cool/cold gas.- there seems to be a characteristic stellar mass ~3x1010M where things change 2 Mar 2006 The galaxies shown in the two upper panels of figure 4 are examples of Sd (NGC 45) and SBd (NGC 2500) types. In NGC 45, the spiral arms are weak and the bulge is very small; the bulge can only contribute a few per cent or less to the total luminosity of the system in this case. Galaxies. • The basic constituents of the universe at large scales, and the building blocks of the large-scale structure. • Have a broad range of physical properties, which presumably reflects their evolutionary and formative histories, and gives rise to various morphological classification schemes (e.g., the Hubble type). Galaxies are the places where gas turns into luminous stars, powered by nuclear reactions that also Galaxies in the Universe: An Introduction. Second Edition. Linda S. Sparke. John S. Gallagher III.
