Research
Extra-Galactic
Extra-galactic astronomy and astrophysics at the University of Michigan encompasses many exciting areas of research and expertise. Areas of special interest include (but are not limited to):
- measuring the masses of supermassive black holes in nearby galaxies;
- surveys (including the Sloan Digital Sky Survey or SDSS) aimed at understanding galactic evolution;
- surveys to reveal the nature of dark energy;
- stellar populations in nearby galaxies;
- theoretical (numerical) studies of galaxy evolution;
- research on galaxy clusters and the warm-hot intergalactic medium;
- gamma-ray bursts and their afterglows; radio and X-ray studies of accretion onto stellar-mass and supermassive black holes in nearby and distant galaxies;
- and gravitational wave signals from distant black hole mergers.

A Census of Star Formation in the Intergalactic Medium: A multi-wavelength study of isolated extragalactic HII regions offers the rare opportunity to examine newly-born stars in an environment vastly different from that of galactic disks. The image by Jess Werk shows Halpha (red) + R-band (blue) image of NGC 1533, marked with locations of spectroscopically confirmed intergalactic HII regions. On the right, The Advanced Camera for Surveys/High Resolution Channel Hubble Space Telescope 3-color images resolve the young star clusters powering the HII regions (blue = UV, green = V, red = I).
