Sentences with phrase «mapping nearby galaxies»
New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey (eBOSS); the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE - 2), including stellar parameter estimates from an innovative data driven machine learning algorithm known as «The Cannon»; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total).

Not exact matches
Astronomers working with the Sloan Digital Sky Survey have used a 2.5 - meter telescope at the Apache Point Observatory in Sunspot, New Mexico, to map the location of more than 930,000 nearby galaxies, determining the distance to each by how much the expansion of the universe has stretched, or «redshifted,» the wavelength of the galaxy's light.
Remarkably, the distribution of star - forming galaxies around a cluster of galaxies in the more distant universe (5 billion years ago) corresponds much more closely with the weak lensing map than a slice of the more nearby universe (3 billion years ago).
They are the locations of bright stars and other nearby objects that get in the way of the observations of more distant galaxies and are hence masked out in these maps as no weak - lensing signal can be measured in these areas.
The scientists from the USA, Australia, and Europe used the powerful DEIMOS spectrograph installed on the world's largest optical telescope at Keck Observatory to conduct a major survey of nearby galaxies called SLUGGS, which mapped out the speeds of their stars.
The Local Volume Mapper will create the first complete spectroscopic maps of several important nearby galaxies.
