Query: Identification of High Mass X-ray Binaries selected from XMM-Newton
  observations of the LMC   The Large Magellanic Cloud (LMC) currently hosts around 23 high mass X-ray
binaries (HMXBs) of which most are Be/X-ray binaries. The LMC XMM-Newton survey
provided follow-up observations of previously known X-ray sources that were
likely HMXBs, as well as identifying new HMXB candidates. In total 19 candidate
HMXBs were selected based on their X-ray hardness ratios. In this paper we
present red and blue optical spectroscopy, obtained with SALT and the SAAO
1.9-m telescope, plus a timing analysis of the long term optical light curves
from OGLE to confirm the nature of these candidates. We find that 9 of the
candidates are new Be/X-ray Binaries, substantially increasing the LMC Be/X-ray
binary population. Furthermore, we present the optical properties of these new
systems, both individually and as a group of all the BeXBs identified by the
XMM-Newton survey of the LMC.
