Her research works are about
galaxy
A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity. The word is derived from the Greek ' (), literally 'milky', a reference to the Milky Way galaxy that contains the Solar System. ...

spiral
In mathematics, a spiral is a curve which emanates from a point, moving farther away as it revolves around the point.
Helices
Two major definitions of "spiral" in the American Heritage Dictionary are:barred structures, and interactions between galaxies, studied both through multi-wavelength observations and by numerical simulations. Additionally, she has published extensively on the
interstellar medium
In astronomy, the interstellar medium is the matter and radiation that exist in the space between the star systems in a galaxy. This matter includes gas in ionic, atomic, and molecular form, as well as dust and cosmic rays. It fills interstella ...
of galaxies. In particular, the molecular gas which gives birth to new stars in nearby galaxies, such as Andromeda, and which can be found in high redshift systems. She has published numerous reviews that range in her areas of interest.
Françoise Combes has contributed to various models of dark matter, and is also interested in alternative solutions, such as modified gravity. She collaborated with Daniel Pfenniger in developing a model to account under the form of cold molecular gas for a large fraction of the dark baryons, which have not yet been identified.
