摘要: We study how gravitational focusing (GF) of dark matter by the Sun affects annual and biannual modulation expected signal in non-directional direct searches, presence substructure local halo. consider Sagittarius stream a possible disk, show that GF suppresses some, but not all, distinguishing features would characterize halo were neglected.
