Final answer:
High-resolution near-infrared imaging of the galactic centers has allowed astronomers to study the orbits of stars near the supermassive black hole, leading to an estimate of the black hole's mass. Large datasets like those of the Sloan Survey illustrate the 'Big Data' era in astronomy, requiring advanced computation for processing.
Step-by-step explanation:
The central portion of kspace is the term used in the context of magnetic resonance imaging (MRI) and relates to the spatial frequency content of the MRI image. In relation to astronomy, the high-resolution near-infrared imaging of the galactic center has allowed astronomers to observe the movements of stars near the center of the Milky Way.
Using these observations in conjunction with Kepler's third law of planetary motion, it is possible to infer the mass of the supermassive black hole at the heart of our galaxy.
Significant efforts in the field of astronomy, such as those by Professor Ghez and the UCLA Galactic Center Group, have been underpinned by sophisticated technology and long-term studies, spanning over two decades.
They have been able to capture super-resolution infrared images with the giant Keck telescopes in Hawaii, allowing the accurate charting of stellar trajectories. These efforts have led to the estimation that the central massive object, a supermassive black hole, has a mass approximately 4.6 million times that of our Sun.
Massive datasets, such as those generated by the Sloan Digital Sky Survey and requiring advanced computational tools for analysis, characterize modern astronomical research. By organizing and sorting vast quantities of data, astronomers continue to unveil the complexities of our universe.
High-resolution images such as those from the Coma Cluster provide invaluable insights into the composition and distribution of interstellar matter within galaxies.
Combining observational data with celestial mechanics highlights the precision and scale of astronomical studies, as it takes a vast amount of skill and technological prowess to reach precise conclusions about the components and mass of the universe.
