Astronomers have observed that they have dubbed the “ghost of dance” deep in space for the first time. The partners in this cosmic dance actually form electrons by the intergalactic air of two supermassive black holes at intervals of one billion light-years. “When we first saw the ghosts of dance ’we had no idea what they were,” said Ray Norris, a professor at Western Sydney University and CSIRO.
“After working for a few weeks, we realized that we were seeing two ‘host’ galaxies about two billion light-years away. At their center were two supermassive black holes, emitting jets of electrons that were then curved in a monstrous shape by intergalactic air. One of the details of a research paper adopted for publication in the publication of the Extraordinary Observations Astronomical Society of Australia – which is available as a print of RXIV – describes the first data of the Evolutionary Map of the Universe (EMU) project.
Named PKS 2130-538, these giant spectral clouds reveal information about the behavior of black holes and what happens in space between galaxies, and, as astronomers readily admit, they throw more questions than ever before. “But new discoveries always raise new questions and it’s not a different one. We still don’t know where the wind is coming from? Why is it so complicated? And what is the cause of the streams of radio emissions?” Professor Norris, the lead author of the study and project for EMU’s pilot survey, said.
The EMU project is not unfamiliar to new and unusual observers. Using CSIRO’s new Australian Square Kilometer Array Pathfinder (ASKAP), a highly sensitive radio telescope that searches deeper into the universe than any other team, the team’s first big “huh?” Last year the discovery was ORCS, a little more formally known as the “Odd Radio Circle”. These seem to be huge rings of radio emissions across about 1 million light-years, around distant galaxies র confusing without any apparent source. They still don’t know what they are.
“We find surprises in places where we thought we understood,” said Professor Norris. “At the side door of the well-trained galaxy IC5063, we found a huge radio galaxy, one of the largest known, whose existence was never suspected. Its supermassive black hole is producing a jet of electrons about 5 million light-years long.” “ASKAP is the only telescope in the world that can see the total amount of this faded emission.”
