A dangerous ring of neutral hydrogen was found around a distant massive galaxy

A dangerous ring of neutral hydrogen was found around a distant massive galaxy: Astronomers using the giant Metroway radio telescope (GMRT) have discovered a very large off-center ring of neutral hydrogen gas around AGC 203001, a massive galaxy located 260 million light years from Earth.

  • This CFHT image shows a huge ring of neutral (red) hydrogen gas around the AGC 203001 galaxy.
  • Two small red spots show the distribution of neutral hydrogen around two other galaxies.
  • The neutral hydrogen gas emits radio waves at a wavelength of approximately 21 cm, said Onkar Bait and colleagues at the National Astrophysics Radio Center of the Tata Institute for Fundamental Research, India.
  • “Usually, large deposits of neutral hydrogen are found in galaxies that are actively forming new stars.”
  • “Despite showing no signs of active star formation, it was known that AGC 203001 contained large amounts of hydrogen, although its exact distribution was unknown.”
  • “The unusual nature of this galaxy led us to use GMRT to make high-resolution radio observations of this gas to find out where this gas is located.”
  • Astronomers discovered that AGC 203001 distributes neutral hydrogen gas around it in the form of a large ring, with a diameter of approximately 380,000 light years.
  • Such an extended structure of neutral hydrogen is very rare in a single case known so far: the Leo ring.
  • More surprising, we found that the current optical images of the ring showed no signs of stars, the researchers said.
  • He also used the Canada-France-Hawaii (CFHT) telescope to see the AGC 203001 ring at visible wavelength.
  • “However, even CFHT images show no signs of starlight attached to the hydrogen ring,” Batt and colleagues said.
  • He said: “There is no clear answer today about what can happen to build such a large and wireless hydrogen ring.”
  • “Traditionally, it was thought that collisions between galaxies and galaxies formed off-center rings around galaxies.”
  • “However, such rings generally also contain stars. This contrasts with that found in the AGC 203001 ring. “
  • “In the future, we hope that by mapping more galaxies using our criteria, there will be an increase in the amount of neutral hydrogen structures so widespread that they can help understand their formation landscape,” the scientists concluded.

A dangerous ring of neutral hydrogen was found around a distant giant galaxy

stronomers discovered a very large off-center ring of neutral hydrogen gas using the Metro Hydrogen Telescope Radio (GMRT) around AGC 203001, one of 260 million. The great galaxy is light. Years away. Earth This CFHT image shows a massive ring of neutral (red) hydrogen gas around the AGC 203001 galaxy.

MUSE reveals a luminous ring of light in the distant universe.

The MUSE instrument in ESO’s Very Large Telescope in Chile has detected a very wide range of neutral hydrogen around distant galaxies. A new result emerges in such an aura, one of them forming a large ring of almost perfect light.
  • The galaxies are surrounded by abundant neutral hydrogen in a region far from its center. This region is very important because it is the location of the gas exchange between the galaxies and their surroundings, and is an important element to understand the formation and evolution of the galaxies. In distant galaxies, this region can be revealed through the glow of the gases emitted in a halo.
  • The images show an overview of two magnified galaxies behind massive galaxy clusters with the NASA / ESA Hubble Space Telescope: pink sparkles reveal distant galaxies and the gas surrounding their structure. The gravitational lens effect of the groups multiplies the images of galaxies, creating 4 images from a single source.
  • The MUSE instrument, which works in the Very Large Telescope of the European Southern Observatory, is very efficient in identifying the aura of almost all distant galaxies, but they are generally too small to show any detail or structure. . The new study combined the power of MUSE with the so-called gravitational lens effect of galaxy clusters.
  • In fact, larger groups have the property of doubling the light rays that pass through its center, as Einstein predicted. This produces a magnifying glass effect: the images of the background galaxies are magnified.
  • The study presents two of the most spectacular observations of the aura of increase obtained to date with MUSE; In one case, the crown represents a large ring of almost perfect light. By approaching such aura of hydrogen around galaxies, it is possible to study for the first time with unprecedented details how the properties of a gas in the aura vary. This information is important to understand the physical processes of playing in the halo, that is, how homogeneous it is and how the gas revolves around the galaxy.
  • Example of a map of the spatial properties of hydrogen gas: MUSE’s observations reveal important variations of the properties of the gas in the crown, allowing us to study in detail the complex structure and physical process of the game.
  • This discovery demonstrates the ability of MUSE combined with the lens effect to study a much larger aura and gain a broader view of the formation of galaxies in the universe when it was only a few billion years old.

  • This CFHT image shows a massive ring of neutral (red) hydrogen gas around the AGC 203001 galaxy. Two small red spots indicate the distribution of neutral hydrogen around the other two galaxies.

“The neutral hydrogen gas emits radio waves at a wavelength of approximately 21 cm,” said Omkar Bait and his colleagues at the National Astrophysics Radio Center of the Tata Institute for Fundamental Research in India.

In general, galaxies have large deposits of neutral hydrogen that actively form new stars. Despite showing no signs of active star formation, it was known that AGC 203001 contained a large amount of hydrogen, although its exact distribution was unknown.

The unusual nature of this gas led us to use GMRT to make high-resolution radio observations of this gas, to find out where this gas is located. Astronomers discovered that AGC 203001 distributes neutral hydrogen gas around it in the form of a large ring with a diameter of approximately 380,000 light years.

In the only known case so far, an expanded structure of neutral hydrogen is so rare: the Leo ring. More surprisingly, we found that the current optical images of the ring showed no signs of the cable, “the researchers said. They also used the Canada-France-Hawaii (CFHT) telescope to view the AGC 203001 ring at visible wavelengths. Yes. Yes. Yes, CFHT images show no signs of starlight attached to the hydrogen ring, “said Bat and his colleagues.

He said: “There is no clear answer today about what could have happened to create such a large and wireless hydrogen ring. Traditionally, it was thought that collisions between galaxies and galaxies would lead to off-center centers around the galaxies.” It will be the center. “Rings are formed. However, such rings generally have rings. Stars It has been found in AGC 203001 rings.

In the future, we hope that by mapping more galaxies using our criteria, the amount of neutral hydrogen structures will increase, allowing them to understand the landscape of their formation, “the scientists concluded. There will be an article published in a monthly article from the Royal Astronomical Society.
