Sentences with phrase «standard cosmological model»

Standard cosmological models of the universe predict the existence of hundreds of dwarf galaxies in orbit around the Milky Way, but their dimness and small size makes them incredibly difficult to find, even in our own «backyard».

In a study in the journal Nature, researchers show that the relative lack of star density in dwarf galaxies need not conflict with standard cosmological models if you include the blast effects of supernovae.

But still not enough to align with predictions based on standard cosmological models.

Standard cosmological models implied that matter in the universe was not concentrated tightly enough to have formed black holes so early on.

Standard cosmological models [the big bang and its variations] implied that matter in the universe was not concentrated tightly enough to have formed black holes so early on.

While many dwarf galaxies surround our own Milky Way, there seem to be far too few of them compared with standard cosmological models, which raises a lot of questions about the nature of dark matter and its role in galaxy formation.

«This really helps reinforce the standard cosmological model, and that makes people's lives easier,» Spergel says.

In the standard cosmological model, matter fluctuations in the early universe are described by a Gaussian probability distribution.

And if they detect merger events beyond that, it means one of two things, Koushiappas and Loeb say: Either primordial black holes exist, or the early universe evolved in a way that's very different from the standard cosmological model.

Such evidence would help confirm the standard cosmological model and give scientists a clue to the underlying cause of the present period of cosmic acceleration.

The standard cosmological model has told us that, because of dark matter, there should be many more dwarf galaxies out there, surrounding our own Milky Way, than we have found.

«Our latest results tie into a clean cosmological picture, giving strength to the standard cosmological model that has emerged over the last eighteen years.»

A paper accepted for publication in the Monthly Notices for the Royal Astronomical Society bolsters the standard cosmological model, or the Cold Dark Matter paradigm, by showing that the vast polar structure formed well after the Milky Way and is an unstable structure.

«This is a big problem that contradicts our standard cosmological models.

In a study recently published in the journal General Relativity and Gravitation, Neves suggests the elimination of a key aspect of the standard cosmological model: the need for a spacetime singularity known as the Big Bang.

According to the standard cosmological model, which predicts how the universe has grown and changed since its earliest days, the universe is filled with enormous strands of dark matter, and the galaxies are embedded in this so - called cosmic web.

The standard cosmological model of structure formation in the universe predicts that galaxies are embedded in a cosmic web of matter, most of which is invisible dark matter.

The standard cosmological model is the frame of reference for many generations of scientists, some of whom are beginning to question its ability to accurately reproduce what is observed in the nearby universe.

The standard cosmological model (called LCDM) incorporates the cosmological constant.

Measurements of large - scale structure in SDSS maps of galaxies, quasars, and intergalactic gas have become a central pillar of the standard cosmological model that describes our understanding of the history and future of the Universe.
