THE TEMPERATURE OF INTERSTELLAR CLOUDS FROM TURBULENT HEATING [PDF]
, 2008 To evaluate the effect of turbulent heating in the thermal balance of interstellar clouds, we develop an extension of the log-Poisson intermittency model to supersonic turbulence.

Putting the Diffuse Interstellar Bands on the map - literally!
, 2013 In a quest to further our understanding of the diffuse interstellar medium (ISM) as well as the unidentified carriers of the diffuse interstellar bands (DIBs), we are mapping DIBs across the sky using hundreds of hot stars as background torches ...

ChemPhysChem, Volume 26, Issue 18, September 19, 2025.In bulk carbonic acid (e.g., in interstellar icy dust grains) cluster formation produces two distinct UV‐Vis spectral features redshifted by ≈2 eV (25 nm) and by ≈5 eV (80 nm) compared to gas phase single molecule carbonic acid 's adiabatic ionization energy. Theory and experiment were used to investigate the origin of these shifts.

Mapping Galactic Dust Emission and Extinction with H I, H II, and H2
The Astrophysical JournalNeutral hydrogen (H i ) emission closely traces the dust column density at high Galactic latitudes and is thus a powerful tool for predicting dust extinction. However, the relation between H i column density N _HI and high-latitude dust emission observed

On the structure of the turbulent interstellar clouds . Influence of the equation of state on the dynamics of 3D compressible flows [PDF]
, 2009 Context. It is well established that the atomic interstellar hydrogen is filling the galaxies and constitutes the building blocks of molecular clouds. Aims. To understand the formation and the evolution of molecular clouds, it is necessary to investigate

Plasma Production by Laser Ablation of Heavy Metals
Contributions to Plasma Physics, Volume 65, Issue 7, August 2025.ABSTRACT An Nd:YAG focused laser operating at 1064 nm, 3 ns pulse width, 360 mJ pulse energy, is employed to irradiate heavy metals, such as Ta, W, Pt, Au, and Pb. The in‐vacuum irradiation produces an expanding plasma at the target surface which has high density, temperature, and kinetic energy of emitted ions. Ions have a velocity of the order of 104

Gas and Dust in Interstellar Clouds [PDF]
Symposium - International Astronomical Union, 1973 Detailed measurements have been made of the H, OH and H2CO lines formed in the L1534 dense dust cloud; some H and H2CO observations have been made of the dust cloud lying behind the Orion cluster. These indicate a similar distribution of the 3 species throughout the dust clouds.

Tracing the Layers of Photodissociated Gas in the Trifid Nebula
The Astrophysical JournalPhotodissociated gas bears the signature of the dynamical evolution of the ambient interstellar medium impacted by the mechanical and radiative feedback from an expanding H ii region.

DESTRUCTION OF THE INTERSTELLAR CLOUDS BY THESHOCK WAVES
Odessa Astronomical Publications, 2008 We study the influence of the interstellar cloud structure irregularity on the dynamics of its destruction by a supernova shock wave. It is shown that irregular clouds are destroyed twice quickly as the spherical ones.

Formation of interstellar clouds: Parker instability with phase transitions [PDF]
, 2009 We numerically follow the nonlinear evolution of the Parker instability in the presence of phase transitions from a warm to a cold H i interstellar medium in two spatial dimensions.
