The Largest Superclusters

Superclusters are vast cosmic structures that contain numerous galaxies bound together by gravity. They represent the largest known gravitationally bound systems in the universe. Superclusters play a crucial role in understanding the large-scale structure and evolution of the cosmos.

• The identification of superclusters is a challenging task due to their immense size and the faintness of their member galaxies. Various methods are employed, including redshift surveys, which measure the redshift of galaxies to determine their distances, and gravitational lensing, which uses the distortion of light from distant galaxies to map the distribution of matter in the universe.

• One of the largest known superclusters is the Shapley Supercluster, located approximately 650 million light-years from Earth. It contains thousands of galaxies and has a diameter of over 1 billion light-years.
• Another notable supercluster is the Coma Supercluster, which is home to the Coma Cluster, one of the richest and most massive galaxy clusters in the universe. The Coma Supercluster spans over 300 million light-years and contains over 10,000 galaxies.
• Superclusters are not static structures but are constantly evolving under the influence of gravity. Galaxies within superclusters interact with each other, merging and forming new structures over time. The study of superclusters provides valuable insights into the formation and evolution of galaxies and the large-scale structure of the universe.

Quasars and Active Galactic Nuclei: What Are The Largest Known Structures In The Universe

Quasars and active galactic nuclei (AGN) are among the most luminous and energetic objects in the universe. They are powered by the accretion of matter onto supermassive black holes at the centers of galaxies.

Quasars are the most luminous type of AGN. They are characterized by their extremely high redshift, which indicates that they are very distant from Earth. The most distant quasars known to date have redshifts of over 7, which means that their light has been traveling for over 13 billion years to reach us.

AGN are less luminous than quasars, but they are still very bright. They are classified into several types, including Seyfert galaxies, radio galaxies, and blazars. AGN are found in all types of galaxies, but they are most common in large, elliptical galaxies.

The energy output of quasars and AGN is thought to be due to the accretion of matter onto a supermassive black hole. As matter falls into the black hole, it is heated to extremely high temperatures and emits large amounts of radiation.

The radiation from quasars and AGN can be seen across the entire electromagnetic spectrum, from radio waves to gamma rays.

Quasars and AGN play an important role in the evolution of galaxies and the universe. They are thought to be responsible for heating the intergalactic medium and driving the evolution of galaxies. They also provide a unique window into the early universe, as they can be seen from very great distances.

Examples of the Largest and Most Luminous Quasars and AGN

• The most luminous quasar known to date is 3C 273. It has a redshift of 0.158 and is located in the constellation Virgo. 3C 273 is so luminous that it can be seen with the naked eye from Earth.

• The most distant quasar known to date is ULAS J1120+0641. It has a redshift of 7.085 and is located in the constellation Leo. ULAS J1120+0641 is so distant that its light has been traveling for over 13 billion years to reach us.

  The largest known structures in the universe are galaxy superclusters, which are vast collections of galaxies bound together by gravity. These superclusters can span billions of light-years and contain trillions of galaxies.

Galaxy superclusters are thought to be the largest coherent structures in the universe, and they play an important role in the formation and evolution of galaxies.

• The largest AGN known to date is the central black hole in the galaxy M87. It has a mass of over 6 billion solar masses and is located in the constellation Virgo. The central black hole in M87 is so large that it can be seen with the Event Horizon Telescope.

Large-Scale Filaments and Voids

The cosmic web is a large-scale structure in the universe that is made up of filaments, voids, and clusters of galaxies. Filaments are long, thin structures that are made up of galaxies and gas. Voids are large, empty regions of space that are surrounded by filaments.

Filaments and voids play an important role in the distribution of galaxies and matter in the universe.

The Largest Known Filaments, What Are The Largest Known Structures In The Universe

The largest known filament is the Sloan Great Wall, which is about 1.37 billion light-years long. It was discovered in 2003 by a team of astronomers led by J. Richard Gott III of Princeton University. The Sloan Great Wall is located about 1 billion light-years from Earth.

Another large filament is the Hercules-Corona Borealis Great Wall, which is about 10 billion light-years long. It was discovered in 2013 by a team of astronomers led by István Szapudi of the Konkoly Observatory in Hungary.

The Largest Known Voids

The largest known void is the Boötes Void, which is about 250 million light-years across. It was discovered in 1981 by a team of astronomers led by Robert Kirshner of the Harvard-Smithsonian Center for Astrophysics. The Boötes Void is located about 600 million light-years from Earth.

Another large void is the KBC Void, which is about 1 billion light-years across. It was discovered in 2013 by a team of astronomers led by Krzysztof Bolejko of the Nicolaus Copernicus Astronomical Center in Poland.

Theories and Observations

The existence and evolution of filaments and voids are supported by a number of theories and observations. One theory is that filaments and voids are formed by the gravitational collapse of dark matter. Dark matter is a type of matter that does not emit or reflect light, so it cannot be seen directly.

However, its presence can be inferred from its gravitational effects on visible matter.

Another theory is that filaments and voids are formed by the expansion of the universe. As the universe expands, the distance between galaxies increases. This causes the galaxies to move away from each other and form filaments and voids.

Observations of the cosmic microwave background radiation support the theory that filaments and voids are formed by the gravitational collapse of dark matter. The cosmic microwave background radiation is the leftover radiation from the Big Bang, the event that created the universe.

The CMB is not uniform, but has slight variations in temperature. These variations are thought to be caused by the gravitational effects of dark matter.

Final Summary

Our exploration of What Are The Largest Known Structures In The Universe culminates in a profound appreciation for the immense scale and intricate interconnectedness of the cosmos. These colossal structures serve as cosmic laboratories, offering invaluable insights into the fundamental processes that govern the universe’s evolution.

As we continue to unravel their secrets, we not only expand our knowledge but also deepen our sense of wonder and connection to the vastness of space.
