\label{ch:conclusion}
The Bolocam Galactic Plane Survey has laid the grounds for an extensive study
of dense gas within our Galaxy.

\chapter{\formaldehyde observations of BGPS sources previously observed with Arecibo}
\label{ch:h2co}
\section{Preface}
Jeremy Darling introduced me to the notion of using \formaldehyde as a gas
densitometer in place of wildly inaccurate `critical-density' based

\formaldehyde fitting. However, there are multiple velocity components in W51,
so I used a two-component (unconstrained) fit for each pixel, which is
frequently unstable but in the case of W51 looks to have produced reasonable
results.
Note that there was \emph{no} \formaldehyde emission detected anywhere
in the W51 region.
A first interesting note is that a local cloud at $v_{lsr}\sim5 \kms$ is
detected in \formaldehyde \oneone across most of the cloud and not detected at

detections and \twotwo nondetections, indicating upper limits $n<10^{3.8}$
(68\% confidence) or $n<10^{4.3}$ (99.7\% confidence).}

There is a large area where \oneone was detected, but \twotwo was not. Our
sensitivity allows us to place a modest upper limit on the gas density, with
$3-\sigma$ upper limits $\lesssim10^{4.3}$ \percc (but the most likely
densities are $10^2 < n < 10^4$ \percc). Figure \ref{fig:w51MCMCcompare} shows
a particular model for a spectrum that is especially unconstrained. The
\oneone/\twotwo optical depth in this object is $\sim10-20$, indicating that
the volume density must be low.

{Plots demonstrating upper limit fits. The left plot shows the allowed
parameter space from MCMC sampling of the data given the RADEX model. The
right plot shows the `best-fit' model, which is clearly unconstrained by the
relatively insensitive \twotwo\ spectrum. The sensitivity in the \oneone line
is better in large part because of brighter 6 cm background across the
whole W51 region. }

The molecular gas is concentrated near, but not exactly on, the bright cm
peaks. W51 IRS2 has a massive clump of gas at 65 \kms, and W51 e2 has a
similar clump. However, e2 also seems to have a very dense ($n>10^5 \percc$)
infalling clump. The spectra, along with multicomponent fits, are shown in
Figure \ref{fig:w51hiispectra}.

{Plots of the spectra centered on W51 IRS2 (left) and W51 e2, an ultracompact HII region (right).
IRS2 shows high-density gas with a slight hint of infall, but otherwise a somewhat vanilla spectrum.
W51e2 has a large, high-density red shoulder, indicating high-density gas at the most red velocity in the system.
Because this is foreground gas, that high-density gas \emph{must} be moving towards the \uchii region.}

\chapter{Using outflows to track star formation in the W5 HII region complex}

the peak of Mauna Kea to perform observations with the JCMT. I spend about 3

\section{Outline}
This thesis includes 5 chapters.
Chapter
2 \ref{ch:w5} describes observations of the W5 star-forming region to identify outflows;
this chapter is somewhat tangential to the rest.
Chapter
3 \ref{ch:v2} describes the BGPS data reduction process and data pipeline.
Chapter
4 \ref{ch:ympc} is a Letter identifying massive proto-clusters in the BGPS.
Chapter \ref{ch:h2co} is the pilot study of \formaldehyde towards previously-known UCHII regions.
It includes the methodology and analysis of turbulent properties of Galactic GMCs.
Chapter
5 \ref{ch:h2colarge} expands upon Chapter
4, \ref{ch:h2co}, detailing the expansion of the \formaldehyde survey
to BGPS-selected sources.
Chapter
6 is a Letter identifying massive proto-clusters in the BGPS.
Chapter 7 \ref{ch:conclusion} concludes.
