Self-consistent model of cosmic ray penetration into molecular clouds: Effect of energy losses
D. O. Chernyshov, A. V. Ivlev, V. A. Dogiel
The theory of cosmic-ray (CR) penetration into dense molecular clouds developed recently for relativistic particles by Chernyshov et al. (2024) is extended to non-relativistic CRs.…
Comprehensive laboratory constraints on thermal desorption of interstellar ice analogues
F. Kruczkiewicz, F. Dulieu, A. V. Ivlev +4
To explain grain growth and destruction in warm media, ice mantle formation and sublimation in cold media, and gas line emission spectroscopy, astrochemical models must mimic the g…
Secondary cosmic-ray nuclei in the Galactic halo model with nonlinear Landau damping
D. O. Chernyshov, A. V. Ivlev, V. A. Dogiel
We employed our recent model of the cosmic-ray (CR) halo to compute the Galactic spectra of stable and unstable secondary nuclei. In this model, confinement of the Galactic CRs is…
Gas phase Elemental abundances in Molecular cloudS (GEMS) VII. Sulfur elemental abundance
A. Fuente, P. Rivière-Marichalar, L. Beitia-Antero +18
Gas phase Elemental abundances in molecular CloudS (GEMS) is an IRAM 30m large program aimed at determining the elemental abundances of carbon (C), oxygen (O), nitrogen (N), and su…
Formation of the cosmic-ray halo: The role of nonlinear Landau damping
D. O. Chernyshov, V. A. Dogiel, A. V. Ivlev +2
We present a nonlinear model of self-consistent Galactic halo, where the processes of cosmic ray (CR) propagation and excitation/damping of MHD waves are included. The MHD-turbulen…
Broadband spectroscopy of astrophysical ice analogues: II. Optical constants of CO and CO ices in the terahertz and infrared ranges
A. A. Gavdush, F. Kruczkiewicz, B. M. Giuliano +7
Context: Broadband optical constants of astrophysical ice analogues in the infrared (IR) and terahertz (THz) ranges are required for modeling the dust continuum emission and radiat…
Self-modulation of cosmic rays in molecular clouds: Imprints in the radio observations
V. A. Dogiel, D. O. Chernyshov, A. V. Ivlev +2
We analyze properties of non-thermal radio emission from the Central Molecular Zone (CMZ) and individual molecular clouds, and argue that the observed features can be interpreted i…
Interstellar dust charging in dense molecular clouds: cosmic ray effects
Alexei Ivlev, Marco Padovani, Daniele Galli +1
The local cosmic-ray (CR) spectra are calculated for typical characteristic regions of a cold dense molecular cloud, to investigate two so far neglected mechanisms of dust charging…
