The Milky Way Galaxy offers a unique opportunity to study the
structure and contents of a major stellar system in three
dimensions, at high spatial and spectral resolution, and to very
large galactocentric distances. This potential can be realised only
by statistical surveys of large areas of the sky, and by detailed
study of specific regions with exceptional properties, such as the
Galactic centre, and of specific classes of object, such as the
globular clusters. The acquisition of such data from a variety of
ground-based and satellite surveys has been a primary topic of
Galactic research for some years. Several such surveys have been
completed recently, and have led to a substantial modification of
our understanding of Galactic structure and evolution. The
importance of the ability of satellite observatories to survey and
to study wavelengths which are inaccessible from the ground is
evident in the wealth of data discussed and analysed in this volume
which is derived from satellites, specifically COS-B, HEAD-I,
HEAO-3, IRAS, PIONEER-lO, SAS-2, and TENMA. The cru cial role of
ground-based observations to complement and comprehend the
satellite data is also well evident. Similarly, the major
ground-based studies whose results are reported here illustrate the
necessity for carefully conceived and executed very large scale
surveys of many types of object and many parts of parameter space
before a coherent picture of the Galaxy will be available."

Fluid dynamical forces drive most of the fundamental processes in
the Universe and so play a crucial role in our understanding of
astrophysics. This comprehensive textbook, first published in 2007,
introduces the necessary fluid dynamics to understand a wide range
of astronomical phenomena, from stellar structures to supernovae
blast waves, to accretion discs. The authors' approach is to
introduce and derive the fundamental equations, supplemented by
text that conveys a more intuitive understanding of the subject,
and to emphasise the observable phenomena that rely on fluid
dynamical processes. The textbook has been developed for use by
final-year undergraduate and starting graduate students of
astrophysics, and contains over fifty exercises. It is based on the
authors' many years of teaching their astrophysical fluid dynamics
course at the University of Cambridge.
