These starbursting galaxies are believed to be progenitors of elliptical galaxies in the cores of today's massive galaxy clusters. In this thesis, multi-wavelength observations of the candidate starbursting protoclusters are shown and their physical properties are : Tai-An Cheng. To understand this, let us take a closer look at the Virgo cluster. It is about 60 million light years away. Irregular in shape and covering about square degrees in the sky (roughly the size of this book held at arm's length), the Virgo cluster contains at least spiral, elliptical, and disk-shaped galaxies. few cluster galaxies have previously resided in groups, so the impact of preprocessing on a typical cluster galaxy must be limited. In Atlee et al. (; henceforth Paper I), we developed a multi-wavelength method to identify AGNs based on either their X-ray luminosities or the shapes of their visible-MIR spectral energy distributions (SEDs).   Spiral galaxies: The Sunflower Galaxy (M63), IC , and NGC Barred spiral galaxies: NGC , NGC , NGC , NGC , and NGC Elliptical galaxies.

These observations (when considered together) suggest that the giant elliptical galaxies that we see nearby formed from a combination of both top-down and bottom-up mechanisms, with the most massive galaxies forming in the densest clusters where both processes happened very early and quickly in the history of the universe. Spiral galaxies form a class of galaxy originally described by Edwin Hubble in his work The Realm of the Nebulae and, as such, form part of the Hubble spiral galaxies consist of a flat, rotating disk containing stars, gas and dust, and a central concentration of stars known as the are often surrounded by a much fainter halo of stars, many of which reside in. This meeting focused on the following topics: 1) star formation thresholds and triggering mechanisms, 2) age-dating of stellar populations, 3) star cluster formation and destruction in interacting galaxies, 4) the nature and role of induced spiral and ring waves, and 5) detailed matching of numerical models to observations of specific systems. most galaxies in the inner region of a large cluster are spirals. F. the Big Bang theory accurately describes all of the observations which have been made by astronomers. F. the Milky Way & Andromeda are both. dislike galaxies with spiral arms are divided into what two subclasses.

In the meantime, Hubble was making observations of galaxies with the meter telescope on Mt. Wilson, which was then the world’s largest. Hubble carried out the key observations in collaboration with a remarkable man, Milton Humason, who dropped out of school in the eighth grade and began his astronomical career by driving a mule train up.
