Description
MAXI J1659-152 was discovered on 2010 September 25 as a new X-ray
transient, initially identified as a gamma-ray burst, but was later
shown to be a new X-ray binary with a black hole as the most likely
compact object. Dips in the X-ray light curves have revealed that MAXI
J1659-152 is the shortest period black hole candidate identified to
date. Here we present the results of a large observing campaign at
radio, submillimetre, near-infrared (nIR), optical and ultraviolet (UV)
wavelengths. We have combined this very rich data set with the available
X-ray observations to compile a broad-band picture of the evolution of
this outburst. We have performed broad-band spectral modelling,
demonstrating the presence of a spectral break at radio frequencies and
a relationship between the radio spectrum and X-ray states. Also, we
have determined physical parameters of the accretion disc and put them
into context with respect to the other parameters of the binary system.
Finally, we have investigated the radio-X-ray and nIR/optical/UV-X-ray
correlations up to ˜3 yr after the outburst onset to examine the
link between the jet and the accretion disc, and found that there is no
significant jet contribution to the nIR emission when the source is in
the soft or intermediate X-ray spectral state, consistent with our
detection of the jet break at radio frequencies during these states.

Accreting black-holes and neutron stars in X-ray binaries provide an ideal laboratory for exploring the physics of compact objects, yielding not only confirmation of the existence of stellar mass black holes via dynamical mass measurements, but also the best opportunity for probing high-gravity environments and the physics of accretion; the most
