1. Phil Plait's Bad Astronomy: Bitesize Astronomy
... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

2. APOD: 2006 May 17 - The Host Galaxies of Long Duration GRBs
... 2006 May 17 . The Host Galaxies of Long-Duration GRBs . Credit: NASA , ESA , Andrew Fruchter ( STScI ), and the GOSH Collaboration . ... These images, shown above , indicate that long duration GRBs typically appear to come from galaxies and regions of galaxies with bright regions rich with star formation and bright, massive stars . Long GRBs are therefore different than many types of supernovas , which occur more uniformly distributed in their host galaxies. ... About APOD | ...

3. Galaxy Gallery Page III
Galaxies are diffuse objects which are imaged against a background of finite brightness and noise. Galaxies which have the maximum contrast with respect to this background are the ones that are first discovered. ... These galaxies have been missed to date but active surveys for them are underway. ... In this page we present several examples of these newly discovered Low Surface Brightness galaxies as well as examples of high surface brightness galaxies. ...

... STScI-PRC00-37 HUBBLE CAPTURES AN EXTRAORDINARY AND POWERFUL ACTIVE GALAXY Resembling a swirling witch's cauldron of glowing vapors, the black hole-powered core of a nearby active galaxy appears in this colorful NASA Hubble Space Telescope image. ... The larger outer ring extends off the image and is in the plane of the galaxy's disk. ... The black hole and its accretion disk are expelling gas out of the galaxy's disk and into its halo (the region above and below the disk). ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

10. Numerical simulations on the relative importance of starbursts and AGN in
We investigate the relative importance of starbursts and active galactic nuclei (AGN) in nuclear activities of ultraluminous infrared galaxies (ULIRGs) based on chemodynamical simulations combined with spectrophotometric synthesis codes. We numerically investigate both the gas accretion rates (ARs; m acc ) on to supermassive black holes (SMBHs) and the star formation rates (SFRs; m sf ) in ULIRGs formed by gas-rich galaxy mergers and thereby discuss what powers ULIRGs. ...

11. ASP: Beacons in the Gloom
... For us to see them from such great distances, quasars must be producing enormous energy -- they are about 1000 times brighter than an average galaxy! ... One of their choices for the energy source of quasars was a black hole. ... On the one hand, it may seem difficult to think that mere friction between bits of matter could account for the energy of a quasar, but, on the other hand, gravity is unimaginably strong near a black hole. ... How does matter actually rush towards the black hole? ...

... Science Users Information > Science Activities > PhD Thesis Topics offered by ESO Faculty Members > Thesis Topic: Planetary Nebulae and HII regions in the Elliptical Galaxy NGC 5128 . ... NGC 5128 is the closest example of a giant early type (elliptical or S0) galaxy. Although often dubbed as a peculiar elliptical galaxy since it has a dust lane with recent star formation and an active galactic nucleus, the majority of early type galaxies have similar structures as revealed by recent surveys. ...
