The Cool ISM in Galaxies

2013
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, 2001
NGC 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 ISM in nearby galaxies

New Astronomy Reviews, 2004
Abstract The SKA will revolutionise the study of the principles underlying star formation (SF), resolving interstellar cloud complexes which are the birthplaces of stars and answering such questions as which are the sufficient and necessary conditions for SF to commence. Also, massive SF is intimately related to stellar death. The SKA will be able to

AKARI observations of the ISM in our Galaxy and nearby galaxies

Advances in Space Research, 2009
Abstract 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).

The Irradiated ISM of Active Galaxies: HCN, HNC, HCO+

EAS Publications Series, 2008
The 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 ISM of Dwarf Galaxies

2011
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 ...
