1. Tour of Centaurus A
QuicktimeMPEG There is nothing subtle about the black hole in the galaxy Centaurus A. First off, itís about 10 million times more massive than the sun, and Chandraís X-ray image shows itís not just sitting quietly as a bright point in the middle. Instead, the monster black hole is responsible for powering massive jets, including one that extends to the upper left for some 13,000 light years. Radio data also show the effect of these jets far beyond the plane of the galaxy. An image in optical light shows the elliptical galaxy and the dark bands running almost perpendicular to the jet. These are caused by dust lanes created when Centaurus A merged with another galaxy, perhaps 100 million years ago. The combination from all of these telescopes shows us just how much is really going on in Centaurus A.

2. Tour of NGC 4258
QuicktimeMPEG The galaxy NGC 4258 has its arms crossed. At least it appears that it does. A composite image of NGC 4258, about 25 million light-years from Earth, shows an X-shaped pattern when seen in different types of light. Infrared radiation from the Spitzer Space Telescope and optical light data from the Digitized Sky Survey show one set of arms, which are made from stars and dust from the galaxy. However, x-ray data from the Chandra X-ray Observatory and radio emission from the Very Large Array reveal a different pair of arms. These dislocated arms are the result of shockwaves, generated by the giant black hole in the center of NGC 4258.

3. Tour of 3C321
QuicktimeMPEG In 3C321, a jet from a black hole in one of the galaxies is pummeling its neighbor galaxy, the first time this type of galactic violence has ever been seen. The jet could bring big trouble for any planets in its path, but could also trigger a burst of star formation in its wake. Beginning with a wide-field view of X-ray and radio emission, we see that the jets from the black hole extend amazingly far, about 1.7 million light-years. Next, we zoom into the two galaxies where most of the action is happening. Radio emission from the Very Large Array and Merlin telescopes, optical and ultraviolet data from Hubble, and X-rays from Chandra all reveal different features of this system. The combined image of all of these data shows how the jet from the galaxy on the lower left impacts the companion galaxy to the upper right. The jet hits the galaxy's edge and is then disrupted and deflected, much like how a stream of water from a hose will splay out after hitting a wall at an angle.

4. Important features of Centaurus A
QuicktimeMPEG This short movie highlights some of the important features of the Chandra X-ray Observatory image of Centaurus A. The entire Chandra image is shown, followed by a zoom into the center of the galaxy where the active nucleus and the launching point for a jet are featured. Particles in the jet and radiation from the active nucleus are both powered by a supermassive black hole. The movie then pans to the upper left to show more of the jet, followed by a view of the shorter "counterjet" pointed in the opposite direction.

5. Multiwavelength views of Centaurus A
QuicktimeMPEG This sequence of images of the galaxy Centaurus A begins with the deep Chandra X-ray Observatory image, then shows the radio image from the Very Large Array, then the optical image from the ESO's Wide-Field Imager (WFI) camera at the ESO/MPG 2.2-m telescope on La Silla. Finally, a composite image with all three wavelengths is shown.

6. Comparison of 3C321 Composite to Artist's Illustration
QuicktimeMPEG
*Broadcast Quality

This sequence compares the composite image of 3C321 to an artist's illustration of the system, showing the main galaxy and the companion galaxy. A jet of particles generated by a supermassive black hole at the center of the main galaxy is striking the companion galaxy. The jet is disrupted and deflected by this impact. The key features of this system are labeled in the final view.

7. Multiwavelength Images of 3C321
QuicktimeMPEG
*Broadcast Quality

This series of images shows how 3C321 looks in a variety of types of radiation. Beginning with a wide-field view of X-ray and radio emission, the image reveals jets that extend for about 1.7 million light years before zooming into the central two galaxies. Optical and ultraviolet data from Hubble, radio emission from the Very Large Array and MERLIN, and X-rays from Chandra combine to reveal how the jet from the main galaxy on the lower left is striking its companion galaxy to the upper right. The jet impacts the companion galaxy at its edge and is then disrupted and deflected, much like how a stream of water from a hose will splay out after hitting a wall at an angle.

8. Animation of 3C321
QuicktimeMPEG
*Broadcast Quality

This animation of 3C321 begins with a close-up of the supermassive black hole in the center of the main galaxy. Hot gas is falling towards the black hole via a blue disk. Some of this material is swallowed by the black hole, but much of it is ejected in a narrow jet of particles traveling at almost the speed of light. The camera then pulls back to show stars and a dust lane in the main galaxy. As the field of view continues to increase in size, the companion galaxy becomes visible as it swings into the path of the jet from the main galaxy. The jet is deflected and disrupted by the impact with the companion galaxy.

9. A Multiwavelength View of NGC 4258
QuicktimeMPEG For decades, astronomers have known about the so-called anomalous arms in the spiral galaxy NGC 4258. This motion graphic shows NGC 4258 from the viewpoint of multiple space and ground-based observations. Visible light (seen in gold) from the Digitized Sky Survey and infrared light (red) from the Spitzer Space Telescope reveals two prominent arms. However, radio data (purple) from the Very Large Array and X-ray data (blue) from Chandra show two additional, offset arms. By combining all of these data, scientists have found evidence that the mysterious X-ray arms are due to shock waves generated by the supermassive black hole in the nucleus of NGC 4258. The shock waves heat the gas in the disk, causing it to radiate brightly in X-rays and other wavelengths.

10. Sequence of M87 Images
QuicktimeMPEG This sequence begins with an optical view of M87, a giant elliptical galaxy only 50 million light years away in the Virgo cluster. X-ray data (red) are then overlaid and reveal a series of loops and bubbles in the hot gas that surrounds the galaxy and fills the cluster. These are evidence of repeated outbursts from close to the supermassive black hole in M87, which are responsible for producing sound throughout the cluster.
