A team of researchers has been hard at work on a new study which aims to explore some of the elusive mechanisms which power black holes. Researchers have managed to track down the composition of the strong galactic winds which are generated by supermassive black holes.
It is thought that these winds may have a powerful influence on how black holes can interact with the galaxies which surround them. Scientists from the Instituto de Astrofisica de Canarias, located in the Canary Islands, elaborated a theory confirmed by their work, which focused on the galactic wind which is released by the black holes.
The discovery offers valuable information on the development and influence exercised by many supermassive black holes which can be found in the centers of a galaxy. During the development process, the black hole grows at an accelerated rate since it consumes a large number of materials, a phenomenon which leads to intense solar winds.
More details on the galactic winds produced by supermassive black holes revealed
The gas found within these galactic winds generated by supermassive black holes, known under the name of active galactic nuclei (also known as AGN), can reach incredible speeds of thousands of kilometers per second. Select AGN are capable of generating quasars, which can consume the material found in the heart of galaxies and prevent the appearance of new stars in those regions.
To find more about the properties of AGN, the researchers decided to use the advanced EMIR infrared spectrograph. This allowed them to observe the winds of ionized and molecular gas released by quasars. Infrared analysis is critical, and it played a crucial role in the project.
Data obtained from the research infers that ionized winds are even faster in comparison to molecular winds. However, the molecular wind pushes the most significant amounts of gas in the galaxy, with a total of 176 solar masses each year. Further research is already underway with the help of ALMA. The study was published in a peer-reviewed journal.
