1. Tour of CDFS
QuicktimeMPEG This animation shows an artist's impression of a distant galaxy and its hidden black hole found in an epoch when the Universe was less than one billion years old. The galaxy contains regions of active star formation (blue) and large amounts of gas and dust (red). The view zooms into the galaxy, and a glowing disk of hot gas falling onto massive central object is seen. At the center of the disk is a supermassive black hole. Many types of radiation emitted from the disk are blocked by the veil of dust and gas, but very energetic X-rays are able to escape. Scientists found many of these black holes in the early Universe using the new Chandra Deep Field South.

2. Multi-wavelength Views of the Chandra Deep Field South
QuicktimeMPEG This sequence of images begins with a large optical image of the southern sky. The view zooms into the 4-million-second exposure of the Chandra Deep Field South, and then an optical and infrared image from the Hubble Space Telescope is overlaid. The Chandra sources are blue in this composite image. After further zooming in, yellow circles appear to mark the positions of very distant galaxies that existed when the Universe was less than about 950 million years old. The two small Chandra sources on the right show that all of the low and high energy X-rays that have been added up at the positions of these galaxies. This provides evidence that growing black holes have been detected in 30% to 100% of the distant galaxies.

4. A Tour of GRS 1915+105
QuicktimeMPEG GRS 1915+105, or GRS 1915 for short, is a special system. Not only does it contain a black hole some 14 times more massive than the Sun in orbit with a companion star, it also has a heartbeat. Or, more exactly, it gives off X-ray pulses that resemble the pattern of a human heart, though on a much slower scale. By monitoring this system with NASA's Chandra X-ray Observatory and the Rossi X-ray Timing Explorer, astronomers were able to pick out a spike of X-rays every 50 seconds or so. Researchers have determined that this heartbeat is due to the ebb and flow of material as it circles the black hole. This result gives scientists more insight into how black holes regulate their intake and control their growth.

5. GRS 1915's "Heartbeat" X-ray Variation
QuicktimeMPEG The heartbeat variation of GRS 1915 is shown here in a repeated cycle to emphasize the similarity between the X-ray light curve and an electrocardiogram. The period has been sped up by a factor of 40.

6. Simulation of GRS 1915's "Heartbeat"
QuicktimeMPEG This movie shows a simulation of the heartbeat variation of GRS 1915. It shows an X-ray point source varying with time, based on an average X-ray light curve of GRS 1915 obtained with RXTE. The period of the heartbeat variation has been sped up by a factor of 10 and four cycles of the variation are shown.

7. A Tour of SN 1979C
QuicktimeMPEG The youngest known black hole in our cosmic neighborhood may have been found using NASA's Chandra X-ray Observatory and other telescopes. Evidence for this very young black hole was found in a supernova called 1979C, seen to explode about 30 years ago. Dr Dan Patnaude of the Harvard-Smithsonian Center for Astrophysics led this study and discusses it with us.

8. Animation of Black Hole Formation in SN 1979C
QuicktimeMPEG This animation shows how a black hole may have formed in SN 1979C. The collapse of a massive star is shown, after it has exhausted its fuel. A flash of light from a shock breaking through the surface of the star is then shown, followed by a powerful supernova explosion. The view then zooms into the center of the explosion. Red, slow-moving material in a disk is shown falling onto the white neutron star that formed when the star collapsed. The rate of infall onto the neutron star increases until the star collapses into a black hole. Matter should continue to fall into the black hole and generate bright X-ray emission for many years.

9. Tour of NGC 7793
QuicktimeMPEG This composite image shows the nearby galaxy NGC 7793 that contains a powerful microquasar in its outskirts. Data from the Chandra X-ray Observatory is colored red, green and blue, while optical data from the Very Large Telescope is light blue, and optical emission by hydrogen, known as "H-alpha", is colored gold. A microquasar is a system in which a stellar-mass black hole is being fed by a companion star. Gas swirling toward the black hole forms a disk around it. Twisted magnetic fields in the disk generate strong electromagnetic forces that propel some of the gas away from the disk at high speeds in two separate jets. These create a huge bubble of hot gas about 1,000 light years across.

10. Tour of M82 and Mid-mass Black Holes
QuicktimeMPEG We begin with a composite image of the nearby starburst galaxy M82 that contains X-rays from Chandra in blue, optical data from Hubble in green and orange, and infrared data from Spitzer in red. Next we zoom into the central region of M82, where just Chandra's view is visible. There we see two bright X-ray sources of special interest. Astronomers think these may be medium-sized black holes. These "survivor" black holes seem to have avoided falling into the center of the galaxy. They could also be examples of seeds required for the growth of supermassive black holes in all galaxies, including the one in the Milky Way.
