Mass outbreaks in the neighboring region of space puzzled astronomers, reports phys.org
"Our observations continued for several years, we found that one galaxy has changed during this time, from the state of rest to a vigorous explosion at the end of " - said Robert Minchin, Arecibo Observatory , who presented the study.
Researchers used a 305-meter telescope William E. Gordon in Arecibo National science Foundation (NSF) for their research when they discovered outbreaks in NGC 660, spiral galaxy, which is at a distance of 44 million light years away in the constellation Pisces. The explosion was ten times brighter than a flash of the largest supernova, or exploding star. They reported their findings at a meeting of the American astronomical society in long beach, California.
After detection of the outbreak, the team continued to watch NGC 660 Arecibo telescope and tried to determine the cause of the explosion. Using a global network of telescopes. Had to do a detailed image of the galaxy. "The high resolution image is the key to understanding what is happening", said Emmanuel Momjian (Momjian), of the National radio astronomy Observatory (NRAO). "We need to know where it was an explosion from a supernova in our galaxy or from the nucleus of the galaxy. We could only do so by using images with high resolution. We received such an image, combining remotely radio telescopes separated"Vkluchaya network High Sensitivity Array (HSA), the Very Long Baseline Array NSF (VLBA) and 100-meter radio telescope of the max Planck Institute in Germany.
Resulting images were more complex than scientists expected. They thought that they will see either an expanding ring of a supernova or a jet of super-fast material from the nucleus of the galaxy. Instead, they saw five of the bright areas of radio emission, one near the center of the Galaxy and two on the sides.
"The most likely explanation is that this stream coming from the kernel, but they precess at or fluctuate, and we see hot spots, where the jet crash into the space near the nucleus of the galaxy", says Chris Salter (Salter), of the Arecibo Observatory. "To verify this, we will continue to observe the galaxy over the next few years," he added.
If the idea of jet correct, the explosion was probably caused by the material, are drawn into a supermassive black hole at the galaxy's center. The material will form a rapidly-rotating disk around the black hole, before finally get it. And the disc will generate a stream of particles exploding outward at near the speed of light. Astronomers are closely monitoring the gas cloud in our own milky Way galaxy, which is expected to be delivered to the Central black hole in our Galaxy in the middle of this year.
