Interstellar medium simulations
Astronomische Nachrichten, 2012AbstractIn this review we critically assess numerical simulations of the interstellar medium (ISM), and argue that 3D high resolution calculations are the most promising method to determine the structure of the interstellar gas and follow its evolution well into the nonlinear regime. Based on a Riemann solver adaptive mesh refinement code, we present a

Small missions for energetic astrophysics, 1999
The study of the interstellar medium has been, and remains, a rich field for exploitation using small missions in the ultraviolet and X-ray spectral regions. I review the history of some such missions (of various sizes), and I also review the capabilities for study of the interstellar medium of “Hot Universe Background Explorer” (HUBE), as it was ...

Turbulence in the Interstellar Medium [PDF]
Astrophysics and Space Science, 2004 Interstellar turbulence is expected to dissipate quickly in the absence of continuous energy input. I examine the energy available for driving the turbulence from six likely mechanisms: magnetorotational instability, gravitational instability, protostellar outflows, H II region expansion, stellar winds, and supernovae.

Astrophysics of the Interstellar Medium
2021This book is based on a series of lectures for an Astrophysics of the Interstellar Medium (ISM) master’s degree in Astrophysics and Cosmology at Padova University. From the cold molecular phase in which stars and planetary systems form, to the very hot coronal gas that surrounds galaxies and galaxy clusters, the ISM is everywhere.

This chapter gives a brief introduction on the interstellar medium (ISM). It starts with an overview (Sect. 1.1) of the ISM properties including some worth-mentioning historical events that took place during its discovery and exploration. We then highlight the importance of the dust in ISM (Sect.

Chemistry in the Interstellar Medium
Annual Review of Physical Chemistry, 1995Over the past 25 years, astronomers have discovered a large number of gas-phase molecules in space, ranging in size up to more than 10 atoms. The molecules, which are mainly organic in nature and comprise both normal and abnormal species, are located between stars, in regions known as interstellar clouds, which contain both gaseous material and ...

The Interstellar Medium and Protostars
2014When we look up into the night sky we see stars, and not much else. So we get the impression that between the stars, space is empty. There doesn’t seem to be any sort of material that lies between one star and another. At the same time, we know intuitively that this cannot be true, for if space were empty, from what did stars form?

Modeling the Local Interstellar Medium
Astrophysics and Space Science, 2001The state of our observational and theoretical knowledge of the local interstellar medium (LISM) is reviewed. The LISM stretches out from the local Cloud, surrounding the solar system to the boundary of the Local Bubble, which is a region of distinct anticorrelation between HI (NH <1020 cm-2) and 1/4 keV diffuse soft X-rays.

Ammonia in the interstellar medium
AIP Conference Proceedings, 1994I discuss the astrophysical importance of ammonia in the interstellar medium with special reference to its’ use as a ‘‘thermometer’’. A very brief overview is given of the observations of interstellar ammonia in cold dark clouds and in hot star forming regions.
