COLLISIONAL EXCITATION OF THE [C ii] FINE STRUCTURE TRANSITION IN INTERSTELLAR CLOUDS [PDF]
, 2012 We analyze the collisional excitation of the 158 μm (1900.5 GHz) fine structure transition of ionized carbon in terms of line intensities produced by simple cloud models.

The Turbulent Interstellar Medium [PDF]
, 2006 An overview is presented of the main properties of the interstellar medium. Evidence is summarized that the interstellar medium is highly turbulent, driven on different length scales by various energetic processes.

TOWARD UNDERSTANDING THE COSMIC-RAY ACCELERATION AT YOUNG SUPERNOVA REMNANTS INTERACTING WITH INTERSTELLAR CLOUDS: POSSIBLE APPLICATIONS TO RX J1713.7−3946 [PDF]
, 2011 Using three-dimensional magnetohydrodynamic simulations, we investigate general properties of a blast wave shock interacting with interstellar clouds.

Large Interstellar Polarisation Survey, II : UV/optical study of cloud-to-cloud variations of dust in the diffuse ISM [PDF]
, 2018 It is well known that the dust properties of the diffuse interstellar medium exhibit variations towards different sight-lines on a large scale. We have investigated the variability of the dust characteristics on a small scale, and from cloud-to-cloud. We

PROPERTIES OF TURBULENCE IN THE VERY LOCAL INTERSTELLAR CLOUDS [PDF]
, 2011 We have investigated the degree to which turbulence in the Very Local Interstellar Clouds resembles the highly studied turbulence in the solar corona and the solar wind, particularly the high-speed solar wind.

Frontiers in Astronomy and Space Sciences, 2023 Combined in situ observations of the interstellar wind through the solar system and of its pickup ions (PUIs), implanted after ionization in the solar wind, explain, in comparison with interstellar absorption lines of nearby stars, that the Sun is in an ...

ON THE DENSITY DISTRIBUTION IN STAR-FORMING INTERSTELLAR CLOUDS [PDF]
TeraGrid Conference, 2010 We use deep adaptive mesh refinement simulations of isothermal self-gravitating supersonic turbulence to study the imprints of gravity on the mass density distribution in molecular clouds.

Interstellar processes: Ortho/para conversion, radiative association, and dissociative recombination
EPJ Web of Conferences, 2015 The study of the ortho-to-para ratio of assorted gas-phase interstellar molecules such as H2, H2O, NH3, and H2O+ has gained interest in recent years, based partially on new spectral observations of light hydrides by the Herschel Space Observatory ...

The chemistry of fluorine-bearing molecules in diffuse and dense interstellar gas clouds
, 2005 We present a theoretical investigation of the chemistry of fluorine-bearing molecules in diffuse and dense interstellar gas clouds. The chemistry of interstellar fluorine is qualitatively different from that of any other element, because - unlike the ...
