Using the Very Large Telescope of the European Southern Observatory, astronomers studied ionized gas in the central regions of the Seyfert galaxy NGC 7130. In their work, the researchers identified a complex, multicomponent release from this galaxy.
Active galaxy nuclei (AJGs) are accreting supermassive black holes (MCHDs) lying in the centers of some galaxies and emitting powerful, high-energy radiation when gas and dust accretion. These emissions are considered to be part of the mechanism for self-regulation of MCHD growth.
The galaxy NGC 7130, located at a distance of about 212 light years from us, is a bright infrared galaxy with an AJG belonging to Seyfert galaxies of type 1.9. In the center of this galaxy are two dust spiral sleeves coinciding with the zones of molecular gas.
A team of astronomers led by Sébastien Comerón from the University of La Laguna, Spain, conducted studies of the interior of the galaxy NGC 7130 in order to better understand the accretion processes of material in the AJG. For this purpose, the researchers used the Multi Unit Spectroscopic Explorer (MUSE) tool of a very large telescope.
Observations revealed nine kinematic components, six of which correspond to the outflow of gas flowing from the galaxy NGC 7130. This release has a biconical shape and is oriented in the north-south direction. The speed of gas movement is about 100 kilometers per second in relation to the disk of the galaxy.
The mass flow rate of this ionized gas is about 1.5 solar masses per year, and its kinetic power is about 340 duodecillion ergs per second, the authors found out. In conclusion, the researchers emphasize the great value that the MUSE tool represents in analyzing the complex structure of gas flows observed by the NSA.
