A HINSA view of cosmic-ray ionization in IC 348 and NGC 1333: evidence for a strong low-energy cosmic-ray disparity
Gan Luo, Marco Padovani, Daniele Galli +5
The cosmic-ray ionization rate (CRIR) is one of the fundamental parameters influencing the chemical and dynamical evolution of molecular clouds. Although observations in recent yea…
New Estimate for the Cosmic Ray-Induced Photodissociation Rate in the Interstellar Medium
O. Sipilä, P. Caselli, M. Padovani +5
In the interstellar medium, cosmic rays (CRs) generate a field of ultraviolet (UV) photons via the excitation and subsequent radiative decay of molecules. This UV field i…
Excitation of molecular hydrogen by cosmic-ray protons
Marco Padovani, Daniele Galli, Corey T. Plowman +4
Low-energy cosmic rays ( GeV) are responsible for the ionisation and heating of molecular clouds. While the role of supra-thermal electrons produced in the ionisation…
The evolution of CH in Planck Galactic Cold Clumps
Gan Luo, Arshia M. Jacob, Marco Padovani +6
Methylidyne (CH) has long been considered a reliable tracer of molecular gas in the low-to-intermediate extinction range. Although extended CH 3.3 GHz emission is commonly observed…
Electron impact ro-vibrational transitions and dissociative recombination of H2+ and HD+: Rate coefficients and astrophysical implications
Riyad Hassaine, Emerance Djuissi, Nicolina Pop +11
Context. Molecular hydrogen and its cation H+2 are among the first species formed in the early Universe, and play a key role in the thermal and chemical evolution of the primordial…
Are Stellar Embryos in Perseus Radio-Synchrotron Emitters? Statistical data analysis with Herschel and LOFAR paving the way for the SKA
Andrea Bracco, Marco Padovani, Daniele Galli +3
Cosmic rays (CRs) are fundamental to the chemistry and physics of star-forming regions, influencing molecular gas ionization, mediating interactions with interstellar magnetic fiel…
Magnetic Fields in Massive Star-forming Regions (MagMaR): Unveiling an Hourglass Magnetic Field in G333.46-0.16 using ALMA
Piyali Saha, Patricio Sanhueza, Marco Padovani +33
The contribution of the magnetic field to the formation of high-mass stars is poorly understood. We report the high-angular resolution (, 870 au) map of the…
Unveiling the role of magnetic fields in an accreting filament onto a young protocluster
Farideh S. Tabatabaei, Elena Redaelli, Daniele Galli +4
In order to develop a more comprehensive picture of star formation, it is essential to understand the physical relationship between dense cores and the filaments embedding them. Th…
Magnetic field dragging in filamentary molecular clouds
Domitilla Tapinassi, Daniele Galli, Marco Padovani +1
Maps of polarized dust emission of molecular clouds reveal the morphology of the magnetic field associated with star-forming regions. In particular, polarization maps of hub-filame…
The Wide-field Spectroscopic Telescope (WST) Science White Paper
Vincenzo Mainieri, Richard I. Anderson, Jarle Brinchmann +214
The Wide-field Spectroscopic Telescope (WST) is proposed as a new facility dedicated to the efficient delivery of spectroscopic surveys. This white paper summarises the initial con…
A new analytical model of the cosmic-ray energy flux for Galactic diffuse radio emission
Andrea Bracco, Marco Padovani, Daniele Galli
Low-frequency radio observations of diffuse synchrotron radiation offer a unique vantage point for investigating the intricate relationship between gas and magnetic fields in the f…
Ultraviolet H luminescence in molecular clouds induced by cosmic rays
Marco Padovani, Daniele Galli, Liam H. Scarlett +5
Galactic cosmic rays (CRs) play a crucial role in ionisation, dissociation, and excitation processes within dense cloud regions where UV radiation is absorbed by dust grains and ga…
Exploring the Formation of Resistive Pseudodisks with the GPU Code Astaroth
Miikka S. Väisälä, Hsien Shang, Daniele Galli +2
Pseudodisks are dense structures formed perpendicular to the direction of the magnetic field during the gravitational collapse of a molecular cloud core. Numerical simulations of t…
