April 2012, 23:54 After the worrisome news for dark matter in the last weeks we have to add another today and there is more to come very soon This time , we show that the disc of satellite galaxies is only a part of a bigger structure : a vast polar structure VPOS of diverse satellite objects surrounds the Milky Way , unexpected from cosmological . models With the increasing resolution of cosmological simulations of structure and galaxy formation , it became possible to make predictions on smaller scales . In particular , it became apparent that the dark matter subhalos , typically identified as the sites of luminous satellite galaxies around a host galaxy , are more

  • Dark Matter gone missing in many places: a crisis of modern physics?

    Updated: 2012-04-19 20:41:18
    : SciLogs All Blogs Next Dark Matter gone missing in many places : a crisis of modern physics from Marcel S . Pawlowski 19. April 2012, 21:41 On The Dark Matter Crisis , we have already presented numerous problems that appear within the LCDM model of cosmology . Some of these have been given names , like the Missing Satellites Problem where LCDM predicts more dark matter subhaloes around the Milky Way than there are observed satellite galaxies , which are expected to trace them . Or the Missing Baryons Problem from cosmological predictions we expect a certain density in the baryonic , luminous and thus in principle observable matter . But when you add up all the visible matter you observed , you only get 10-40 per cent of what you expect . The larger fraction is missing . Even the ongoing

It is titled "Physik vor dem Kollaps - Die Wissenschaft steht im Dunkeln". It includes an interview with Pavel Kroupa. For those without TV: the programme can already be found online in the 3sat Mediathek and will be available for the next seven days.

    : SciLogs All Blogs Next Question D : What about the Bullet cluster And what about the Train-Wreck cluster Abell 520 from Pavel Kroupa 15. April 2012, 20:15 : Summary One result is very definite by now : neither the Bullet nor the Train Wreck clusters support nor do they prove the existence of cold or warm dark matter . And , they certainly do not disprove MOND . Quite on the contrary , according to current knowledge , they falsify the concordance cosmological or LCDM . model The Bullet cluster consists of two clusters of galaxies that have penetrated each other leaving behind a slab of gas while the now seperating clusters retain matter as revealed through gravitational lensing . Assuming General Relativity GR to be valid t he lensing measurements tell us that collisionless dark matter

The silver lining, as they see it, is that they have the chance to reevaluate their plans and find a path forward. DOE [...]

  • Stars containing dark matter should look different from other stars

    Updated: 2012-02-20 15:40:01
    (PhysOrg.com) -- Finding evidence for dark matter – the unknown substance that theoretically makes up 23% of the universe – has been one of the biggest challenges in modern cosmology. Several experiments are underway to detect dark matter candidates known as Weakly Interacting Massive Particles (WIMPs) as they travel through the Earth. And experiments at the Large Hadron Collider (LHC) are trying to produce WIMPs through proton beam collisions. Now in a new study, scientists have shown that feebly annihilating dark matter particles captured inside a star can provide an additional source of energy to the star, resulting in changes to its structure and appearance. Observing these stars could potentially offer scientists a tool to detect and analyze this kind of dark matter.
