Single galaxy

The astronomers found that NGC 4178 galaxy there are other galaxies do not have the characteristics of "alone" it seems to enjoy the single life from the galaxy as a whole contour point of view, seems to be rather flat, a regular disc galaxies, but also hasthe periphery of the graceful spiral structure. Scientists by surprise, the galaxy's central black hole seems to be more perfect, not too big, but also not too small. The NGC 4178 galaxy where the universe in a unique position in the past should not have to participate in the tragic event of galaxy collisions, and in the next period of his career will continue to maintain this "single" way to spend.

 

The NGC 4178 galaxy maximum is characterized by the huge bulge of the galaxy central is not ugly, the characteristics of the black hole mass there is a big relationship, and the galaxy alone in a dark space. From NGC 4178 galaxy recently, several clusters of galaxies, they become more active together through collisions, merging eventually evolved into a large spiral galaxy, the center of the galaxy there are various quality grades of black holes. the continued occurrence of collision makes the black hole is also increasing, until it reaches billions of times the mass of the sun, the scene is the most direct manifestation of the huge bulge for the galaxy central, like an impressive expansion of the stomach. The NGC 4178 galaxy like this happens, the contour remains that it appears to have been "trimmed" looked on.The eyes of the astronomers, such as NGC 4178 galaxy such strange objects known as "cosmic hermit, withdrawn galaxies in the universe is unusual. The researchers believe that the growth and evolution of galaxies formed in the collision and merger events of star clusters, such as the Milky Way is that evolution of the formation of elegant peripheral spiral arm galaxy. However, the growth of distance of the NGC 4178 galaxy seems different, to avoid collision with other galaxies, the more often the existence of "loner" in most of the time in his life, therefore, scientists hope to use The existing observational tools and theory to uncover the mysterious galaxy of life experience.-According to researchers at George Mason University in Fairfax, Virginia: "The loner galaxies is typical of the early universe objects, can be traced back to the structure of galaxies in the universe began to take shape. Scientists believe that such as NGC 4178 this galaxy, we can derive as much as possible early universe. can help us solve the multiple universe problems, such as the mystery of the origin of the black hole. "most of the galaxy center seems to have a giant black hole, their quality can reach the mass of the sun hundreds of times, or billions of times. However, the black hole is how to become so huge? This is still a mystery.The scientists speculate that the growth history of the black hole by the quality of the smaller number of black hole through the host galaxy collisions, mergers, eventually evolved into the supermassive black holes, or it may have originated in the early universe, a giant gas cloud collapse events. If the black hole growth is through consolidation, phagocytosis, then the universe should be filled with different quality levels of the black hole, in the current black hole theory, the quality of a black hole in the number of times the mass of the sun known as low-mass black hole, if black hole growth through continuous merging, then a good number of low-mass black holes should exist in the universe, but scientists rarely found that they exist.Therefore, the NGC 4178 galaxy has never happened galaxy collisions, merger events can be speculated that the formation mechanism of its central black hole is indeed worthy of study, showing lack of due galaxy central uplift. Description: According to the researchers, we have observations of NGC 4178 galaxy around, trying to find a strange galaxy of the central government did not uplift, but the current search results show that the central fact in many galaxies there are black holes. Researchers suggest that, whether this is the discovery of the disappearance of intermediate-mass black hole and his colleagues found by calculating the quality of the black hole from between the the 10000-100 times the mass of the sun, if the black hole mass in the galaxy NGC 4178 in the range of minimum value, then it may be round minimum mass black hole found in disk galaxies, being engulfed the surrounding material growth.In fact the center of the galaxy was born in the era of the early universe there is less quality and the growing black hole, but lower mass black holes may not be through events such as collisions, mergers, the evolution growth, but need to devour the surrounding material accumulated become larger. In other words, NGC 4178 galaxy central black hole may be a "seed black hole" is a classic example of a supermassive black hole appears.But scientists believe that the NGC 4178 galaxy will not always be in a "state of the" single Guling the edge of the galaxy in the Virgo cluster of galaxies into clusters of galaxies, one hundred million years after a certain period and in the future and the other planets The collision of the merger. The galaxy central seed black hole "may evolve into a supermassive black hole, like the other galaxies in the Virgo cluster of galaxies, then this alone" single galaxy "will have a companion galaxy.
