The Vera Rubin Observatory (VRO) will use time-domain observations of quasars to search for binary supermassive black holes (SMBHs). The VRO will be a powerful tool for detecting or characterizing SMBHs.
When galaxies merge, they can produce binary black holes (BBHs). BBHs orbit each other closely, and when they merge, they produce gravitational waves. The LIGO-Virgo has detected these gravitational waves.
SMBHs are the largest type of black hole. They have a mass that is hundreds of thousands, or millions to billions, of times the mass of the Sun. Observational evidence indicates that almost every large galaxy has a supermassive black hole at its center
Here’s How. When galaxies merge, we expect them to produce binary black holes (BBHs.) BBHs orbit one another closely, and when they merge, they produce gravitational waves that have been detected by LIGO-Virgo
Supermassive black holes (SMBHs) are black holes with masses between 100,000 and 10 billion times greater than the Sun’s mass. They are extremely large and condensed, and their gravitational force increases as distance decreases.
SMBHs are theorized to exist at the center of almost all large galaxies. They power active galactic nuclei, such as quasars and Seyfert galaxies.
As of 2022, there are over 150 confirmed SMBHs in our local Universe. Some SMBHs have masses of several billion solar masses
Ultramassive black holes (UMBHs) are the most massive objects in the universe. They have masses between 10 billion and 40 billion times the mass of the Sun. UMBHs are rare and elusive, and their origins are unclear. Some believe they were formed from the merging of galaxies billions of years ago.
Supermassive black holes (SMBHs) are the largest type of black hole. They have masses that are more than 1 million suns together. SMBHs are found at the centers of most galaxies, including our own Milky Way galaxy
The four types of black holes are: Stellar, Intermediate, Supermassive, Miniature.
The most common way a black hole forms is through stellar death. Stellar black holes form from massive stars. As a star ages, gravity pushes inward and radiation pressure pushes outward.
Other types of black holes include: Primordial, Micro, Intermediate-mass.
Black holes are invisible because no light can escape their strong gravitational pull.
The Vera C. Rubin Observatory (VRO) is an astronomical observatory under construction in Chile. The observatory is located on the Cerro Pachón ridge in north-central Chile. It features an 8.4-meter telescope and a 3200 megapixel camera
The VRO is a joint project of the National Science Foundation and the U.S. Department of Energy. The project was originally authorized to cost $473 million, but is currently being re-baselined due to the COVID-19 pandemic.
The VRO will perform a multi-year survey that repeatedly images the sky for changes. The observatory will answer some of the biggest questions about the universe.
The VRO was previously known as the Large Synoptic Survey Telescope (LSST). It was named after Vera Rubin, a dark matter scientist who faced discrimination and bias throughout her career.
