The astronomers have identified nine rings using NASA/ESA Hubble Space Telescope and WM KECK Observatory’s KECK COSMIC Web Imager (KCWI) data.
Pasha et al。 Nine rings around the Leda 1313424, a ring galaxy, about 567 million lights, have been detected around the constellation of Pisces. They also confirmed that the galaxy had pigeons and created these rings through the Reda 1313424. Image Credit: NASA / ESA / HUBBLE / IMAD PASHA & Pieter Van Dokkum, Yale University.
LEDA 1313424 A ring galaxy found in the image of Legacy Survey Dr9 in 2019.
The galaxy called Bulls Eye’s nickname has an reddish transition of Z = 0.0394 corresponding to the distance of 567 million light years.
The diameter of LEDA 1313424 is 250,000 light years. This is almost 2.5 times that of the Milky Way galaxy.
“This was an accidental discovery,” said Imado Pasha, a student in the Yale University doctoral course.
“I was looking at a ground -based imaging survey, but when I saw a galaxy with some transparent rings, I was immediately drawn to it. I had to stop to investigate it. did.”
Approximately 50 million years ago, a small blue dwarf galaxy moved like a dart that passed the core of LEDA 1313424.
With this collision, 10 rings were created around LEDA 1313424. This has detected nine unprecedented rings.
A thin gas trail links the pair, but is currently 130,000 light years away.
“We are catching Bulls Eye at a very special moment,” said Professor Peter Van Dockm of Yale University.
“When there are many rings in such a galaxy, there is a very narrow window after the impact.”
Researchers used Hubble’s clear vision to identify the eight rings of LEDA 1313424 and check another ring using KECK.
They also discovered a brilliant connection between Ring Galaxy and many years. The galaxy ring seems to have moved almost exactly as expected as the model predicted.
“The theory was developed on the day I saw a lot of rings,” said Professor Van Dokum.
“I am very pleased to confirm the predictions for these years in the Bulls Eye Galaxy.”
From the top, it is clear that the Galaxy ring is not evenly spaced like a Dart board. The image of Hubble shows the galaxy from a slight angle.
“If you look down on the galaxy directly, the ring looks circular, the ring will be bundled in the center, and will gradually be far away and gradually break away,” Pasha explained.
a paper Regarding this discovery, it was released today Astronomical physics journal letter。
