%K cosmology, halo.
%X Different studies show that dark matter of non-baryonic origin might exist. There is experimental evidence that at least one form of dark matter has been detected through microlensing effects. This form of dark matter is named MACHOs (massive astrophysical compact halo objects). The MACHO collaboration estimated that the masses of these objects are to be in the range 0.15–0.95M_, where the most probable mass is of 0.5M_. Some authors argue that MACHOs could be black holes, and that they could form binary systems, BHMACHO binaries. As is well known, binary systems are sources of gravitational waves. The Brazilian spherical antenna will operate in the frequency band of 3.0–3.4 kHz, sensitive to binaries of a pair of 0.5M_ black holes just before coalescing. In the present work we study the detectability of these putative BHMACHO binaries by the Brazilian spherical antenna Mario Schenberg.
