NASA/IPAC Extragalactic Database

Last updated

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. NED is funded by NASA and is operated by the Infrared Processing and Analysis Center (IPAC) on the campus of the California Institute of Technology, under contract with NASA. [1]

Contents

NED is built around a master list of extragalactic objects for which cross-identifications of names have been established, accurate positions and redshifts entered to the extent possible, and some basic data collected. Bibliographic references relevant to individual objects have been compiled, and abstracts of extragalactic interest are kept on line. Detailed and referenced photometry, position, and redshift data, have been taken from large compilations and from the literature. [2] [3]

NED also includes images from 2MASS, [4] from the literature, and from the Digitized Sky Survey. [5]

As of March 2014, NED contains 206 million distinct astronomical objects with 232 million cross-identifications across multiple wavelengths, with redshift measurements for 5 million objects, 1.9 billion photometric data points, 609 million diameter measurements, 71 thousand redshift-independent distances for over 15 thousand galaxies, 310 thousand detailed classifications for 230 thousand objects, and 2.6 million images, maps and external links, together with links to 65 thousand journal articles, notes and abstracts.

NGC 4606 is a spiral galaxy located about 55 million light-years away in the constellation of Virgo. NGC 4606 was discovered by astronomer William Herschel on March 15, 1784. It has a disturbed stellar disk suggesting the actions of gravitational interactions. NGC 4607 may be a possible companion of NGC 4606. However, their redshifts differ by about 600 km/s, making it unlikely that they are a gravitationally bound pair. NGC 4606 is a member of the Virgo Cluster.

<span class="mw-page-title-main">NGC 4598</span> Galaxy in the constellation Virgo

NGC 4598 is a barred lenticular galaxy located in the constellation Virgo. NGC 4598 was discovered by astronomer William Herschel on April 15, 1784. The distance to NGC 4598 has not been accurately determined; measurements vary from 64 to 102 million light-years. According to the NASA/IPAC Extragalactic Database, its redshift based distance is 102 Mly (31.3 Mpc) while its redshift independent based distance is 88.71 Mly (27.200 Mpc). Also, according to SIMBAD, its distance is 63.7 Mly (19.54 Mpc). NGC 4598's average distance is 84.8 Mly (26.0 Mpc). NGC 4598 is usually considered to be a member of the Virgo Cluster. However, P. Fouqu´e et al. suggests it may be a background galaxy independent of the main cluster.
