Ay 212 Readings: Dark Matter
The Nature of the Dark Matter:
I was unable to find a single, comprehensive, modern review of this subject.
Thus, I am asking you to select and read at least two papers from the
following list or your own searches of
astro-ph.
An old review by V. Trimble
(1987, ARAA, 25, 425)
provides a good historical introduction. Take a look also at

The subject is now divided into two parts: baryonic and non-baryonic DM.
On the baryonic front, the interesting possibilities include
MACHOs,
cold gas, and
warm gas.
A very brief (and perhaps biased) summary is given by Freese et al.,
http://xxx.lanl.gov/abs/astro-ph/0002058
-
For MACHOs, search the astro-ph for Alcock (author) or MACHO (title), and
take your pick. However, a good, short summary of references is also
given by Paczynski,
http://xxx.lanl.gov/abs/astro-ph/9910327
-
For cold gas, see the paper by Combes & Pfenniger,
http://xxx.lanl.gov/abs/astro-ph/9602145
-
For warm gas, see, e.g., the paper by Cen & Ostriker,
ApJ, 514, 1 (1999)
On the non-baryonic front, the currently favored candidates include massive
neutrinos, WIMPs and axions.

A good introductory review is by D. Spergel, in "Unsolved Problems in
Astrophysics", eds. J. Bahcall and J. Ostriker, p. 221, Princeton Univ.
Press (1997); a book you may wish to own. Also available at
http://xxx.lanl.gov/abs/astro-ph/9603026
-
Several papers by M. Kamionkowski, e.g.,
http://xxx.lanl.gov/abs/astro-ph/9809214,
http://xxx.lanl.gov/abs/hep-ph/9710467,
or
http://xxx.lanl.gov/abs/hep-ph/9609531.
-
Marc also recommended
several other papers.
-
Laboratory detection experiments are discussed, e.g., in
http://xxx.lanl.gov/abs/astro-ph/0003434
and
http://xxx.lanl.gov/abs/astro-ph/9911260.
Take a look also at the April issue of Physics Today, p. 17.

Another good review is by Bergstrom,
