Distribution In General > s.a. dark matter [and large-scale structure];
dark-matter detection; fractals in physics.
* 1996: Orbiting Japanese X-ray telescope
ASCA indicates that dark matter is hierarchical, congregates in galaxies and clusters
[@ Ikebe et al Nat(96)feb].
* 2005: Lensing analysis by
Natarajan et al show excellent agreement with "concordance model"
at galactic scales.
* 2006: Study of 12 Milky Way
satellites with VLT shows it clumps at scales above 300 pc, with typical speed 9 km/s.
* 2007: Dark-matter map
by COSMOS team shows overlap with luminous matter at large scales
[@ Massey et al Nat(07)jan
+ pw(07)jan].
* 2008: Colliding clusters
MACSJ0025 show separation of dark matter (lensing) and ordinary hot gas (X rays),
similar to the Bullet Cluster.

* 2011: The core-cusp problem remains one
of the unsolved discrepancies between observations and theory in cold-dark-matter scenarios.
* 2017: Distant galaxies appear to lack dark
matter, contrary to expectations and galaxy formation theories, and based on star velocity measurements.

Galaxy Clusters
* Dark matter decay: Could be detected
by observing photons with high spatial resolution, to determine whether they come from
a region that agrees with the mass distribution obtained from lensing (dark matter)
or that obtained from X-rays (hot baryonic matter).
