abstract = "The interest in gravitational waves (GW) has increased since the
recent detections of such signals announced by the LIGO Scientific
Collaboration and the Virgo Collaboration. On the other hand, also
interesting is the study of the stochastic backgrounds of GW
(SBGW), which could in principle be generated by a variety of
sources and astrophysical processes; particularly, in the present
paper we are concerned with the SBGW from MACHO binaries in the
Galaxy. In our scheme, we take into account only MACHOs which are
black holes (BHMACHOs) and are located up to 50 kpc from the
center of the Galaxy. Our spectra, which are calculated in the
scenarios with \Ω h2= 0.1 and \Ω h2= 1.0 , are
parameterized by the fraction of the Galaxys dark halo mass which
is in the form of BHMACHOs and are compared with some results
found in the literature. Besides, we investigate in what
situations the backgrounds are above the sensitivity curves of the
Laser Interferometer Space Antenna (LISA), Einstein Telescope
(ET), Advanced Virgo (AdV) and Advanced Laser Interferometer
Gravitational-Wave Observatory Plus (LIGO A+).",
