Enhancing our Search for Missing Intermediate Mass Black Holes Using Advanced LIGO

The current generation of ground-based gravitational-wave detectors are most sensitive to mergers of intermediate-mass black holes (IMBH), with search volume of cosmological distances of redshift $\sim 1$ and detectable total-mass up to $\sim 1000 M_\odot$. Two independent searches for binary black holes, matched-filtering and transient burst, are specifically configured to look for IMBH binaries in Advanced LIGO. I summarize the results from both these searches during the first observing run of Advanced LIGO and narrate our plans to enhance detection volume and detectable total-mass.
