Finally a new "Dark Matter Crisis" blog post: My take on the reported "detection" of dark matter in the "innermost" Milky Way and what it means for MOND.
Spiral galaxies rotate too fast. If they would only consist of the visible (baryonic) mass we observe in them and Newton's Law of gravity is correct, then they

And another paper on the VPOS around the Milky Way. Most of our satellite galaxies co-orbit in the same plane. This is inconsistent with cosmological predictions but expected for tidal dwarf galaxies. In addition, this phase-space coherence allowed us to predict the proper motions for the satellites for which no measurements are available.
Abstract: The satellite galaxies of the Milky Way (MW) define a vast polar structure (VPOS), a thin plane perpendicular to the MW disc. Proper motion (PM) measurements are now available for all of the 11 brightest, `classical' satellites and allow an updated analysis of the alignment of their ...

The science blog by Pavel Kroupa and me has recently been discontinued, the reason given to us was that the "thesis pushed by The Dark Matter Crisis is now overwhelmingly considered incorrect by the scientific community and as such cannot be considered sound enough to be promulgated by SciLogs.com”. We have succeed to get the blog re-opened now, and I have published the story behind this attempted censorship. The ridiculous attack was initiated by a blogger and former scientist who (to put it mildly) dislikes MOND.

If you are worried about this attempted scientific censorship and other difficulties faced when communicating controversial science, have a look at my blog post. Feel free to express your opinion on this incident in the comments, too.

Please also share the link. In particular scientists should be made aware of this situation.

After a long blog break, here is my new SciLogs post. I'm writing about the vast rotating disc of satellite galaxies around Andromeda. Most of the current news articles on this topic emphasize how surprising, unexpected and mysterious the structure is. This is why I decided to discuss the interpretation in a bit more detail: a promising explanation is already available and should be considered.

With this post we are also moving our "The Dark Matter Crisis" blog from scilogs.eu to scilogs.com. Pavel and I would very much appreciate it if you could support our move by sharing this new link.

My new paper is out: Ever wondered if planes of co-orbiting satellite galaxies like the VPOS are more likely around hosts which are part of a Local Group like halo pair than around isolated hosts? They aren't:
Abstract: Sub-halos in dark-matter-based cosmological simulations tend to be distributed approximately isotropically around their host. The existence of highly flattened, co-orbiting planes of satellite galaxies has therefore been identified as a possible problem for these cosmological models, ...

Our new paper about the frequency of rotating satellite galaxy planes in cosmological simulations: In contrast to previous claims, the satellite structures are not easily understood in standard galaxy formation theory.
Abstract: Both major galaxies in the Local Group host planar distributions of co-orbiting satellite galaxies, the Vast Polar Structure (VPOS) of the Milky Way and the Great Plane of Andromeda (GPoA). The $\Lambda$CDM cosmological model did not predict these features. However, according to three ...

Paper accepted
Abstract: Both major galaxies in the Local Group (LG) are surrounded by thin planes of mostly co-orbiting satellite galaxies, the vast polar structure (VPOS) around the Milky Way (MW) and the Great Plane of Andromeda (GPoA) around M31. We summarize the current knowledge concerning these ...

A post by Scott Dodelson on dark matter and modified gravity. 
It's a comment on what recently happend to the dark matter crisis blog (the whole story has been summarized here: http://www.scilogs.com/the-dark-matter-crisis/)
and how critique in science should not be. 

http://www.scilogs.com/the-dark-matter-crisis/2013/03/09/scott-dodelson-on-dark-matter-and-modified-gravity-guest-post/a
Following the recent attempt to close our blog The Dark Matter Crisis, we and the SciLogs team decided to invite a renown colleague to comment on this issue by writing a guest blog post. Thinking abou...
