Star Formation in Luminous LoBAL Quasars at 2.0<z<2.5
  Low-ionisation broad absorption line quasars (LoBALs) mark an important, yet
poorly understood, population of quasars showing direct evidence for energetic
mass outflows. We outline a sample of 12 luminous (L$_{\rm{bol}}$
$>$10$^{46}$ergs$^{-1}$) LoBALs at 2.0$<$z$<$2.5 - a key epoch in both star
formation and black hole accretion, which have been imaged as part of a
targeted program with the \textit{Herschel} Spectral and Photometric Imaging
REceiver (SPIRE). We present K-band NOTCam spectra for three of these targets,
calculating their spectroscopic redshifts, black hole masses and bolometric
luminosities, and increasing the total number of LoBAL targets in our sample
with spectral information from five to eight. Based on FIR obeservations from
\textit{Herschel} SPIRE, we derive prolific SFRs ranging 740 -
2380M$_{\rm{\odot}}$yr$^{-1}$ for the detected targets, consistent with LoBALs
existing in an evolutionary phase associated with starburst activity.
Furthermore, an upper limit of $<$440M$_{\rm{\odot}}$yr$^{-1}$ is derived for
the non-detections, meaning moderate-to-high SFRs cannot be ruled out, even
among the undetected targets. Indeed, we detect an enhancement in both the SFRs
and FIR fluxes of LoBALs compared to HiBAL and non-BAL quasars, further
supporting the evolutionary LoBAL paradigm. Despite this enhancement in SFR
however, the environments of LoBALs appear entirely consistent with the general
galaxy population at 2.0$<$z$<$2.5.
