The interstellar cloud surrounding the Sun: a new perspective [PDF]
, 2014 Aims: We offer a new, simpler picture of the local interstellar medium, made of a single continuous cloud enveloping the Sun. This new outlook enables the description of a diffuse cloud from within and brings to light some unexpected properties. Methods:

Mid-infrared Spectroscopy of Protonated Benzonitrile, 2-Cyanonaphthalene, and 9-Cyanoanthracene for Astrochemical Consideration. [PDF]
ChemphyschemExperimental infrared absorption spectra of three protonated cyano‐substituted PAHs measured by infrared multiple photon dissociation using the free‐electron laser Free‐Electron Laser for Infrared eXperiments are studied. These spectra are compared to an emission spectrum measured by JWST, and the largest measured protonated cyano‐PAH, cyanoanthracene,

Revisiting CN<sup>-</sup> Formation Mechanisms in Electron Collisions with Benzonitrile. [PDF]
ChemphyschemThis study explores negative ion formation via electron attachment, revealing CN− formation at 3.0 and 7–10 eV. Dissociation pathways are analyzed using G4(MP2) and CASPT2 calculations, highlighting the coupling between the π4* and σ* resonances critical for interstellar chemistry. Radiation‐induced processes in the aromatic cyano compound benzonitrile

Microstructure of the Local Interstellar Cloud and the Identification of the Hyades Cloud [PDF]
, 2001 We analyze high-resolution UV spectra of the Mg II h and k lines for 18 members of the Hyades Cluster to study inhomogeneity along these proximate lines of sight.

Atomistic Modeling of Methyl Formate and Glycolaldehyde Formation on Interstellar Dirty Ice Mantles via a "Radical + Ice" Mechanism. [PDF]
ChempluschemThe presence of interstellar complex organic molecules (COMs) has been baffling astrochemists for a long time. Methyl formate and glycolaldehyde are widely detected but their abundances mismatch kinetic astrochemical model predictions. Here, the formation of these two COMs is characterized onto a mixed ice surface, highlighting the importance of ...

An Ice Age JWST inventory of dense molecular cloud ices [PDF]
Nature Astronomy, 2023 Icy grain mantles are the main reservoir of the volatile elements that link chemical processes in dark, interstellar clouds with the formation of planets and the composition of their atmospheres.

The Interface between the Outer Heliosphere and the Inner Local ISM: Morphology of the Local Interstellar Cloud, Its Hydrogen Hole, Strömgren Shells, and 60Fe Accretion [PDF]
Astrophysical Journal, 2019 We describe the interface between the outer heliosphere and the local interstellar medium (LISM) surrounding the Sun. The components of the inner LISM are the four partially ionized clouds (the Local Interstellar Cloud (LIC), G cloud, Blue cloud, and Aql

Profiles of interstellar cloud filaments. Observational effects in synthetic sub-millimetre observations [PDF]
, 2012 Sub-millimetre observations suggest that the filaments of interstellar clouds have rather uniform widths and can be described with the so-called Plummer profiles. The shapes of the filament profiles are linked to their physical state.

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
