Amazon Redshift is a data warehouse product which forms part of the larger cloud-computing platform Amazon Web Services. [1] It is built on top of technology from the massive parallel processing (MPP) data warehouse company ParAccel (later acquired by Actian), [2] to handle large scale data sets and database migrations.
The NASA/IPAC Extragalactic Database (NED) is an online astronomical database for astronomers that collates and cross-correlates astronomical information on extragalactic objects (galaxies, quasars, radio, x-ray and infrared sources, etc.). NED was created in the late 1980s by two Pasadena astronomers, George Helou and Barry F. Madore.
NGC 1163 is located in the constellation Perseus, which is best observed during winter in the Northern Hemisphere. The galaxy lies roughly 205 million light-years from Earth, as determined by its redshift (z = 0.0151).
Using Hubble's law, the redshift can be used to estimate the distance of an object from Earth. By combining redshift with angular position data, a redshift survey maps the 3D distribution of matter within a field of the sky. These observations are used to measure detailed statistical properties of the large-scale structure of the universe.
NGC 3261 is a barred spiral galaxy in the constellation Vela.The galaxy lies about 110 million light years away from Earth based on redshift, which means, given its apparent dimensions, that NGC 3261 is approximately 130,000 light years across. [1]
William G. Tifft was an astronomer at the University of Arizona.His main interests were in galaxies, superclusters and redshift quantization. [1] He was influential in the development of the first redshift surveys, and was an early proponent of crewed space astronomy, conducted at a proposed Moon base for example.
The Center for Astrophysics (CfA) Redshift Survey was the first attempt to map the large-scale structure of the universe.. The first survey began in 1977 with the objective of calculating the velocities of the brighter galaxies in the nearby universe by measuring their redshifts at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts.
Q0906+6930 was the most distant known blazar [1] (redshift 5.47 / 12.2 billion light years) [2] at the time of its discovery in July, 2004. The engine of the blazar is a supermassive black hole (SMBH) approximately 2 billion times the mass of the Sun [3] (the mass of the Milky Way Galaxy is around 1.5 trillion solar masses).
