4 CHAPTER 1. INTRODUCTION Figure 1.2: Galactic rotation curve for galaxy NGC3198 [4]. The non-Keplerian behavior of the flat rotation curve (instead of 1/ √ r) indicates a large fraction of the galactic mass is non-luminous. The dashed line corresponds to the mass distribution of visible matter. The dotted line corresponds to the distribution of gas. The dotdashed line corresponds to the mass distribution of the non-luminous halo. in the form of a non-luminous halo. The entire dark matter halo may be comprised of normal baryonic matter that is in a form that we cannot see. The current favored dark baryon objects are Massive Compact Halo Objects (MACHOs). Two experiments [6, 7] have undertaken searches for MACHOs which can be observed through gravitational microlensing of distant stars. Both experiments observe a number of events that indicate the presence of MACHOs, however, neither experiment finds a sufficient number of events to support the claim that the majority of the dark matter halo is comprised of MACHOs. Fig. 1.4 shows exclusion plots from a combined analysis of the data from both experiments [8] which indicates that less than 25% of the galactic halo is in the form of MACHOs with masses 10 −7 M ⊙ m 10 −3 M ⊙ . These measurements suggest that most of the dark matter halo must be in the form of an exotic particle that is not currently part of the Standard Model.
1.1. HINTS OF PHYSICS BEYOND THE STANDARD MODEL 5 Figure 1.3: Average rotation curves for ∼1000 spiral galaxies. Each plot shows the average rotation curve (solid line) for galaxies with the indicated luminosities (in absolute magnitude). The dotted lines corresponds to the contribution from the visible disc and the dashed lines correspond to the contribution from a dark halo. Figure from [5].
