AKARI observations of the ISM in our Galaxy and nearby galaxies
Advances in Space Research, 2009Abstract With AKARI, we have systematically performed near- to far-infrared (NIR–FIR) observations of the interstellar medium (ISM) in our Galaxy and nearby galaxies as one of AKARI mission programs called ISMGN (ISM in our Galaxy and Nearby galaxies).

This chapter describes the different constituents of the observable interstellar medium (ISM) in galaxies and reviews the relationships between the ISM and the star formation in galaxies. The emphasis is on the component which is most widespread and most easily observable, the neutral atomic hydrogen ( H I).

RAM-Pressure Stripping of a Galaxy's ISM
Astrophysics and Space Science, 2001NGC 4485 is a late-type galaxy moving through the very extended HI envelope of its companion, NGC 4490. NGC 4485 is undetected in HI,CO and IRAS wavebands, but a peak at all of these frequencies is seen displaced from the optical disk. HI data show a prominent bow-shock ahead of this displaced gas.

The state of the interstellar medium (ISM) of dwarf galaxies is reviewed, thereby emphasizing three different phases, namely the neutral, the hot and the nonthermal ISM. The distribution and structure of the more diffuse neutral ISM is discussed mainly on the basis of observations of the neutral hydrogen (HI), while that of the dense gas relies mostly ...

The Warm Component of the ISM of Elliptical Galaxies
1992The characteristics of the optical emission-line gaseous component of elliptical galaxies are reviewed. We focus on three questions — the origin and fate of the gas and its excitation. The relative merits of accretion or infall events and cooling-flows are compared with regard to these questions. The cooling-flow model has the largest number of hurdles

The Irradiated ISM of Active Galaxies: HCN, HNC, HCO+
EAS Publications Series, 2008The nuclei of active galaxies harbor massive young stars, an accreting central black hole, or both. Results are presented for molecular gas that is exposed to X-rays (1-100 keV, XDRs) and far-ultraviolet radiation (6-13.6 eV, PDRs). Particular attention is paid to species like HCN, HNC and HCO(+).

The Early ISM and Galaxy Formation
1990I review current ideas about galaxy formation, concentrating on when and how it occurred, and what it might look like. As theoretical ideas have been refined, it has become clear that galaxy formation may be both less spectacular and more recent than originally predicted.
