Diffuse interstellar medium and the formation of molecular clouds [PDF]
, 2009 (Abridged) The formation of molecular clouds (MCs) from the diffuse interstellar gas appears to be a necessary step for star formation, as young stars invariably occur within them. However, the mechanisms controlling the formation of MCs remain controversial.

Can diffuse X-rays be important in driving photoionisation in molecular clouds?
Astronomy & AstrophysicsContext. The ionisation balance in molecular clouds is regulated by several ionising sources, including cosmic rays, X-rays, and ultraviolet radiation. Their relative importance depends on the local physical conditions and on the shielding column density.

Dissociative Recombination of CH+ Molecular Ion Induced by Very Low Energy Electrons
Atoms, 2019 We used the multichannel quantum defect theory to compute cross sections and rate coefficients for the dissociative recombination of CH + initially in its lowest vibrational level v i + = 0 with electrons of incident energy below 0 ...

Towards an anagraphical picture of high-energy Galactic neutrinos [PDF]
EPJ Web of Conferences, 2019 The TeV/PeV neutrino emission from our Galaxy is related to the distribution of cosmic-ray accelerators, their maximal energy of injection as well as the propagation of injected particles and their interaction with molecular gas.

Nonthermal Chemistry in Diffuse Clouds with Low Molecular Abundances
The Astrophysical Journal, 2003 High quality archival spectra of interstellar absorption from C I toward 9 stars, taken with the Goddard High Resolution Spectrograph on the Hubble Space Telescope, were analyzed. Our sample was supplemented by two sight lines, 23 Ori and B1 Sco, for which the C I measurements of Federman, Welty, & Cardelli were used.

The co transition from diffuse molecular gas to dense clouds: Preliminary results [PDF]
, 2016 The atomic to molecular transitions occurring in diffuse interstellar gas surrounding molecular clouds are affected by the local physical conditions (density and temperature) and the radiation field penetrating the material.

Adenosine triphosphate as a modulator of protein interactions and stability
FEBS Open Bio, EarlyView.ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...
