Space is only noise, a famous musician states on the cover of its much appreciated album. Space is noise and plenty of other things that fascinatingly unfold in front of our very eyes, making our mother planet look small and insignificant in comparison to the huge and mysterious other celestial bodies. Supermassive black holes can be measured with the help of ALMA, a very performant telescope that helps scientists delve on the mysteries of space.
Black holes are one of the greatest mysteries alive and it seems that now a team of astronomers has opened the Pandora box, to our amazement. Ever since black holes were spotted under astronomic observatories, people have wondered how they work, what are the properties they hold on to and how does their interaction with space happen.
Recent research conducted by The Graduate University for Advanced Studies has been observing the barred spiral galaxy NGC 1097 with the ALMA telescope and concluded that the super massive black hole has a mass that is 140 million times larger than the mass of the sun. Supermassive indeed, everyone will say, and the reported findings are fascinating to say the least.
Researchers determined that this galaxy holds a giant mass of black matter in comparison with the one observed at the center of the Milky Way which is a very lightweight one, with a mass of just a few million times larger than the Sun’s mass.
This is the very first time when the ALMA telescope gave a considerable helping hand to scientists to make such an impressive measurement for a spiral or barred spiral galaxy. This supermassive black hole is situated 45 million light years away in the course of the Fornax Constellation. As researchers reported, there seems to be a strong connection between the black hole’s mass and the central luminosity of the host galaxy.
Scientists have managed to discover the precious findings by measuring the distribution of hydrogen cyanide and formylium molecules in the central are of the NGC-1097, the supermassive black hole we are talking about. Consequently they examined the gravitational motion of molecular gas with the help of astrophysical models. The gas motion was calculated by making models assuming various cases.
The results offered clues related to the properties between black holes and galaxies, which indicates that further information on the celestial bodies may appear somewhere in the near future.
