The impact of ionised outflows from z$\sim$2.5 quasars is not through
  instantaneous in-situ quenching: the evidence from ALMA and VLT/SINFONI
  We present high-resolution ($\sim$2.4\,kpc) ALMA band 7 observations
(rest-frame $\lambda \sim 250\mu$m) of three powerful z$\sim$2.5 quasars
($L_{\rm bol}=10^{47.3}$-$10^{47.5}$ ergs s$^{-1}$). These targets have
previously been reported as showing evidence for suppressed star formation
based on cavities in the narrow H$\alpha$ emission at the location of outflows
traced with [O~{\sc iii}] emission. Here we combine the ALMA observations with
a re-analysis of the VLT/SINFONI data to map the rest-frame far-infrared
emission, H$\alpha$ emission, and [O~{\sc iii}] emission. In all targets we
observe high velocity [O~{\sc iii}] gas (i.e.,
W80$\sim$1000--2000\,km\,s$^{-1}$) across the whole galaxy. We do not identify
any H$\alpha$ emission that is free from contamination from AGN-related
processes; however, based on SED analyses, we show that the ALMA data contains
a significant dust-obscured star formation component in two out of the three
systems. This dust emission is found to be extended over $\approx$1.5--5.5\,kpc
in the nuclear regions, overlaps with the previously reported H$\alpha$
cavities and is co-spatial with the peak in surface brightness of the [O~{\sc
iii}] outflows. In summary, within the resolution and sensitivity limits of the
data, we do not see any evidence for a instantaneous shut down of in-situ star
formation caused directly by the outflows. However, similar to the conclusions
of previous studies and based on our measured star formation rates, we do not
rule out that the global host galaxy star formation could be suppressed on
longer timescales by the cumulative effect of quasar episodes during the growth
of these massive black holes.
