Local void consistency with Lambda CDM cosmology

[Chronos]

This paper - The Local Void: for or against ΛCDM?,http://arxiv.org/abs/1401.6459 - puts to the test the question of low galaxy counts in the vicinity of the Milky Way. It has been suggested this poses a problem for LCDM. Using the Millennium II supercomputer at the Max Planck Supercomputer Center, a ten billion particle dark matter numerical analysis was performed and revealed such voids are not only possible, but, probable under reasonable LCDM assumptions.

Interesting. I wonder how long it took them to calculate that, lol.

The millennium II run required 1.4 million cpu hours over 2048 cores. In other words, the supercomputer required about a month to crunch all the numbers.

Very cool. More or less what I expected. The ΛCDM model has proven to be remarkably resilient, and I really think it's a bad idea to bet against it.
