Abstract
This thesis presents three higher-mass star forming regions (Mon R1, Mon R2 and
NGC 2264) as observed by Herschel, and also the JCMT (SCUBA-2), and the IRAM
30-m telescope, with additional data from the Spitzer and WISE archives. The Herschel
observations, using the SPIRE and PACS instruments over a range of 70 m{500 m,
were taken as part of the HOBYS Key Programme, and the data were reduced using
the HIPE mapmaking environment with sources identified and characterised by the get-
sources routine. The Herschel observations cover the peaks of cold dust SEDs, allowing
robust estimates of mass and temperature to be made.
Comparisons of the Herschel observations of the three regions suggest a picture
of star formation in which the densest parts of certain molecular clouds can accrete
matter via filaments from the surrounding regions, fuelling far more star formation
than occurs in the outer regions. My study of these regions has led to the potential
classification of two separate regimes of star formation. The �first occurs in �filamentary
regions (generally observed with a column density of 3 � 1021 c
