\chapter{Conclusions}
\label{ch:conclusion}
The
key conclusions of this thesis are divided into two components. The first
centers on the Bolocam Galactic Plane Survey
and its high-level results.
The BGPS has laid the grounds for an extensive study of dense gas within our
Galaxy.
It is the first blind survey of the Galactic plane at millimeter
wavelengths, where optically thin dust emission dominates the observed signal.
\begin{itemize}
\item The BGPS has had two data releases and its
pipeline has been well-characterized. The angular transfer function drops
from $100\%$ recovery at 100\arcsec to $\sim50\%$ recovery at 300\arcsec.
\item The BGPS map power spectra, when compared with Herschel Hi-Gal power
spectra, indicate that in some portions of the galaxy, the smallest
scales are \emph{warmer} than the largest scales, hinting that internal
heating by forming young stars is significant.
\item There are 3 massive proto-clusters in the northern Galactic plane,
G10.62, W49, and W51.
\item There are about 20 `clumps' of mass $M\gtrsim10^4$ \msun in the northern
plane.
\item All of these clumps are forming massive stars at present, implying that
the starless timescale for the parent clumps is $\tau_{starless}<0.5$ Myr.
\item The BGPS and comparable ground-based surveys are excellent tools for
identifying the precursors to massive clusters. Because the galaxy is transparent
at 1.1 mm, the BGPS can be used for galaxy-wide population analyses
\item Careful distance determination is crucial for population studies
\end{itemize}
% I examined the brightest sources within the BGPS, discovering 18 with masses
% $M>10^4$ \msun, large enough to form bound clusters. These sources are all
% actively star-forming and can now be used for unbiased proto-cluster population
% studies. These observations allow us to place an upper limit on the starless
% lifetimes of young massive clusters $\tau_{starless} < 0.6$ Myr.
The second component is a study of gas density and turbulence. The probability
distribution of gas density in the interstellar medium is generally thought to
be governed by turbulence, which robustly delivers a lognormal probability
distribution for density and velocity. Turbulence requires a driving force on
large scales to maintain such a distribution, so I examined both its potential
drivers and measures of the distribution.
I performed follow-up studies with \formaldehyde observations from the Green
Bank Telescope and Arecibo Observatory. With these observations, I measured

allowed some signal-processing features to be added to the BGPS pipeline that
could not be included in the original Bolocam pipeline.
\subsection{Pyflagger}
\url{http://agpy.googlecode.com/svn/trunk/agpy/pyflagger.py}\\
Pyflagger was originally intended as an interactive data-flagger for Bolocam
data, and was used as such, but it ended up being a complete data visualization
tool as well, implementing nearly the entire pipeline process within itself so
that each step could be easily visualized. Much of the pipeline debugging and
methodology development was performed using pyflagger. The interactive
flagging involves key and mouse commands to the \texttt{matplotlib} GUI.
Pyflagger uses the \texttt{idlsave} package to read IDL save files.
