What phenomenon is described in the context of NGC 1068?

NGC 1068, also known as M77, is one of the most studied active galactic nuclei (AGNs) and is particularly notable for its supermassive black hole at the center. The phenomenon associated with NGC 1068 includes the outflows of gas that are driven by the intense energy produced as matter accelerates and spirals into the black hole. When matter falls into the supermassive black hole, it releases vast amounts of energy, often in the form of powerful jets or winds of gas that can blow away surrounding material, affecting the galaxy's evolution.

This outflow of gas is significant because it can regulate star formation in the host galaxy and contribute to the feedback processes that shape the galactic environment. In the case of NGC 1068, observations have shown that gas is indeed being expelled from the region around the black hole, indicating a dynamic interaction between the black hole and its surrounding matter.

In contrast, the other options refer to different astronomical phenomena. Dark matter detection involves searching for evidence of non-visible mass in the cosmos, baryon acoustic oscillations relate to the fluctuations in density of baryonic matter in the early universe, and high-energy cosmic rays are charged particles from outer space.
