JWST observations of cosmic-ray-excited H in Barnard 68: spatial variations and constraints on cosmic-ray attenuation

David A. Neufeld, Kedron Silsbee, Alexei V. Ivlev +9

We present James Webb Space Telescope (JWST) NIRSpec observations of the starless dark cloud Barnard 68 that reveal the spatially-resolved signature of cosmic-ray excited molecular…

Mapping the Cosmic-Ray Ionization Rate in the Local Galaxy with H

Nick Indriolo, Alexei V. Ivlev, T. Pellegrin +6

Chemistry in diffuse molecular clouds relies primarily on rapid ion-molecule reactions. Formation of the initial ions, H and H, is dominated by cosmic-ray ionization of H…

Formation of protostars and the launching of stellar core outflows with moving-mesh radiation non-ideal magnetohydrodynamics

Alexander C. Mayer, Rüdiger Pakmor, Thorsten Naab +5

We present an implementation of radiative transfer with flux-limited diffusion (FLD) for the moving-mesh code {\small AREPO} and use the method in a physical model for the formatio…

Broadband spectroscopy of astrophysical ice analogues: III. Scattering properties and porosity of CO and CO ices

A. A. Gavdush, A. V. Ivlev, K. I. Zaytsev +5

The quantification of the terahertz (THz) and IR optical properties of astrophysical ice analogs, which have different molecular compositions, phases, and structural pro…

The first detection of cosmic-ray excited H in interstellar space

Shmuel Bialy, Amit Chemke, David A. Neufeld +12

Stars and planets form within cold, dark molecular clouds. In these dense regions, where starlight cannot penetrate, cosmic rays (CRs) are the dominant source of ionization -- driv…

Protostellar disks in their natural habitat -- the formation of protostars and their accretion disks in the turbulent and magnetized interstellar medium

Alexander C. Mayer, Thorsten Naab, Paola Caselli +6

We present simulations of the supernova-driven turbulent interstellar medium (ISM) in a simulation domain of volume within which we resolve the formation of pro…
