What is the dark energy dominated era?
The dark-energy-dominated era began after the matter-dominated era, i.e. when the Universe was about 9.8 billion years old.
In the era of cosmic inflation, the Hubble parameter is also thought to be constant, so the expansion law of the dark-energy-dominated era also holds for the inflationary prequel of the big bang..
When did dark energy dominate?
It could measure what was going on 5 billion years ago using bright galaxies and 10 billion years ago using bright quasars.
But it had nothing about what was going on in-between.
Unfortunately, this time period is most likely when dark energy started dominating..
The Baryon Oscillation Spectroscopic Survey (BOSS) will map out the baryon acoustic oscillation (BAO) signature with unprecedented accuracy and greatly improve the constraints on the acceleration of the expansion rate of the Universe.

The Extended Baryon Oscillation Spectroscopic Survey (eBOSS) will precisely measure the expansion history of the Universe throughout eighty percent of cosmic history, back to when the Universe was less than three billion years old, and improve constraints on the nature of dark energy.

eBOSS concentrates on the observation of galaxies and quasars, in a range of distances (redshifts) currently left completely unexplored by other three-dimensional maps of large-scale structure in the Universe. In filling this gap, eBOSS creates the largest volume survey of the Universe to date.

Does EBOS own animates?

EBOS also acquires 50 per cent of the Animates pet store group.
EBOS divests its portfolio of scientific businesses in NZ and Australia to the number two global scientific supply company based in the USA.
EBOS Group revenues exceed $1 billion for the first time.

Does eBOSS follow up on X-ray sources?

eBOSS also includes ,two subprograms to follow up on other types of objects:

the Time-Domain Spectroscopic Survey (TDSS) for variable objects

and the SPectroscopic IDentification of ERosita Sources (SPIDERS) for X-ray sources.

What does eBOSS stand for?

The latest and final data release of optical spectra from the SDSS component extended Baryon Oscillation Spectroscopic Survey (eBOSS), including:

the spectra of the SPectroscopic IDentfication of ERosita Sources (SPIDERS) survey and Time Domain Spectroscopic Survey (TDSS).

What is eBOSS cosmological analysis?

The cosmological analysis from BAO, RSD, and other probes provides 1% precision constraints on the cosmological model, with major advances enabled by the SDSS legacy surveys.
The full list of publications from eBOSS includes ,studies of cosmology, galaxy science, and quasar physics.
