Extreme Turbulence Roiling 'Most Luminous Galaxy' in the Universe
Extreme Turbulence Most Luminous Galaxy the Universe
2016/2/22
The most luminous galaxy in the Universe – a so-called obscured quasar 12.4 billion light-years away – is so violently turbulent that it may eventually jettison its entire supply of star-forming gas, ...
The Einstein universe is the conformal compactification of Minkowski space.
It also arises as the ideal boundary of anti-de Sitter space. The purpose of this article is
to develop the syntheti...

Milky Way-Like Galaxies May Have Existed in the Early Universe
Milky Way-Like Galaxies Early Universe
2015/8/13
A new, large-scale computer simulation has shown for the first time that large disk galaxies, much like our own Milky Way, may have existed in the early days of the universe.
ALMA Witnesses Assembly of Galaxies in the Early Universe for the First Time
ALMA Witnesses Assembly of Galaxies Early Universe First Time
2015/8/4
The Atacama Large Millimeter/submillimeter Array (ALMA) has detected the most distant clouds of star-forming gas yet found in normal galaxies in the early Universe. The new observations allow astronom...
Green Bank Telescope Joins 'Breakthrough Listen' to Vastly Accelerate Search for Intelligent Life in the Universe
Green Bank Telescope Breakthrough Listen Vastly Accelerate Search Intelligent Life the Universe
2015/8/4
The National Science Foundation’s Green Bank Telescope (GBT) will join in the most powerful, comprehensive, and intensive scientific search ever for signs of intelligent life in the Universe. The inte...
New model of cosmic stickiness favors “Big Rip” demise of universe（图）
cosmic stickiness favors Big Rip demise of universe
2015/7/13
The universe can be a very sticky place, but just how sticky is a matter of debate.That is because for decades cosmologists have had trouble reconciling the classic notion of viscosity based on the la...
Dark matter is a scientific mystery. We can't see or touch it. But physicists like Dan McKinsey theorize it must exist because, without it, the universe would look quite different.With support from th...
A handful of new stars are born each year in the Milky Way, while many more blink on across the universe. But astronomers have observed that galaxies should be churning out millions more stars, based ...
“Assassin” Targets Supernovae in Our Neighborhood of the Universe（图）
Assassin Targets Supernovae Our Neighborhood the Universe
2015/1/20
The strategy is paying off. At the American Astronomical Society (AAS) meeting in Seattle this week, researchers reported early successes from the All-Sky Automated Survey for Supernova...
I highlight results from Chandr observations of nearby galaxies, including the Milky Way. These observations have offered insights into old mysteries and indications of new high energy astrophysical p...
The clustering dipole of the local universe from the Two Micron All Sky Survey
galaxies clusters
2014/12/24
The unprecedented sky coverage and photometric uniformity of the Two Micron All Sky Survey (2MASS) provides a rich resource for investigating the galaxies populating the local universe. A full charact...
Galaxy clustering and galaxy bias in a Lambda CDM universe

2014/12/24
We investigate galaxy clustering and the correlations between galaxies and mass in the ΛCDM cosmological model (inflationary cold dark matter with Ωm = 0.4, ΩΛ = 0.6, h = 0.65, n = 0.95, and σ8 = 0.8)...
Observations of the Gas Reservoir Around a Star Forming Galaxy In The Early Universe
general individual (A1689)
2014/12/23
We present a high signal-to-noise spectrum of a bright galaxy at z = 4.9 in 14 h of integration on VLT FORS2. This galaxy is extremely bright, i850 = 23:10 0:01, and is strongly-lensed by the foregr...

2014/12/23
We study the formation of galaxies in a large volume (50 h−1 Mpc, 2 × 2883 particles) cosmological simulation, evolved using the entropy and energy-conserving smoothed particle hydrodynamics (SP...
