Luque's team examined ground-based data stretching back to 1998 from the European Southern Observatory and the Las Campanas Observatory in Chile, the W.M. Keck Observatory
in Hawaii, and the Calar Alto Observatory in Spain, among many others.
Spectra was collected at the W.M. Keck Observatory
in Hawaii using a spectrograph built at UCLA by a team led by colleague James Larkin.
Through the help of Hawaii's W.M. Keck Observatory
, the origin of the burst was pinpointed to a galaxy that's 7.9 billion light years away.
Astronomer Richard Ellis of the European Southern Observatory said in an email that the luminosity the group claims is three times higher than that of similar bodies "at much later times," and that astronomers seeking to measure distances greater than redshift 10 usually do so in conjunction with powerful ground-based telescopes such as the ones at the W.M. Keck Observatory
Hamilton; and Tennessee State University, Nashville, found the planets using measurements from the Automated Planet Finder (APF) Telescope at Lick Observatory in California, the W.M. Keck Observatory
on Maunakea, Hawaii, and the Automatic Photometric Telescope (APT) at Fairborn Observatory in Arizona.
As astronomers lose the functionality of existing observatories to light pollution, and move to places like Mount Graham in Arizona and on Mauna Kea, the location of the W.M. Keck Observatory
in Hawaii, they've been protested, sued and made to feel like wanton intruders, wreckers of the environment, and defilers of traditionally sacred spaces.
The new finds were made by a consortium that pored over previous data and added new observations using ESO's hi-tech observatory and US Magellan telescopes in Chile and the W.M. Keck Observatory
The scientists also used data from the Sloan Digital Sky Survey, the W.M. Keck Observatory
on Mauna Kea, Hawaii and the MMT Observatory on Mount Hopkins, Arizona.
New observations from the W.M. Keck Observatory
in Hawaii and the Hubble Space Telescope reveal 33 merged galaxies in which pairs of supermassive black holes are "waltzing" around the galactic centers.
NASA plans to build up to six telescopes at a cost of $50 million to augment existing equipment at the W.M. Keck observatory
, which is managed by the University of Hawai'i.
Spectra -- collected at the W.M. Keck Observatory
in Hawaii using a spectrograph built at UCLA by a team led by colleague James Larkin -- provide the third dimension, revealing the star's motion at a level of precision not previously attained.
