Satellite dwarf galaxies at the edges of the Milky Way and neighboring Andromeda defy the accepted model of galaxy formation, and recent attempts to pigeon-hole them into the model are flawed, an international team of scientists reports.
The mismatch raises questions about the accuracy of the standard model of cosmology, which is the widely accepted paradigm for the origin and evolution of the universe, the astrophysicists say.
A preprint of the research paper, accepted for publication by the Monthly Notices of the Royal Astronomical Society, is online here.
The standard model, also called the “lambda cold dark matter model,” says that satellite dwarf galaxies in the Milky Way and Andromeda are expected to behave a certain way: The galaxies would form in halos of dark matter, be widely distributed and would have to move in random directions, said Marcel Pawlowski, a postdoctoral researcher in the astronomy department at Case Western Reserve University and lead author of the new study.
“But what astronomers see is different,” Pawlowski said. “We see the satellite galaxies are in a huge disk and moving in the same direction within this disk, like the planets in our solar system moving in a thin plane in one direction around the sun. That’s unexpected and could be a real problem.”

‘All and Everything’ returns to SOTT Talk Radio this week to offer our listeners a show packed with ‘condensed Truth’ on various different current (and perhaps not-so-current) topics. We’ll aim to deal with each discrete topic in about 5 minutes and then see if our analysis leads us to an overall view of ‘life on planet earth’.
What’s the weather like where you are? More importantly, what are the people like where you are? Are they getting worked up about the state of the economy? Are they noticing the extreme and unusual weather events? Or are they just totally oblivious to anything beyond their daily routines?
Even at its current distance, the comet is already active as sunlight warms the surface and causes frozen volatiles to sublimate. Comets become more active as they near the inner solar system, where the Sun’s heat evaporates their ices into jets of gases and dust.
LOAD OF BALONEY. They get brighter because they are electrically active.
Atmospheric scientist Bill Nichols offers a refreshing reconsideration of climate issues, with emphasis on the electrodynamic environment of the Earth, largely overlooked in the polarized debates on climate change.
