Dark Matter Realism

Singlet scalar dark matter in noncommutative space

In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered,  but our information about  the nature of dark matter is still limited. There are such particle candidates as  scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...

Dark matter and dark radiation

Lotty Ackerman, Matthew R. Buckley, Sean M. Carroll, and Marc Kamionkowski California Institute of Technology, Pasadena, California 91125, USA (Received 16 December 2008; published 23 January 2009) We explore the feasibility and astrophysical consequences of a new long-range Uð1Þ gauge field (‘‘dark electromagnetism’’) that couples only to dark matter, not to the standard model. The dark matter...

Dark Matter and Dark Energy

I briefly review our current understanding of dark matter and dark energy. The first part of this paper focusses on issues pertaining to dark matter including observational evidence for its existence, current constraints and the ‘abundance of substructure’ and ‘cuspy core’ issues which arise in CDM. I also briefly describe MOND. The second part of this review focusses on dark energy. In this pa...
