End-to-end differentiable retrieval of molecular spectra using hydrodynamics, chemistry, and radiative transfer
T. Grassi, G. Vermariën, J. E. Pineda +3
We aim to reproduce observed molecular line emission using a pipeline that couples hydrodynamics, chemistry, and radiative transfer, capable of simultaneously optimizing all releva…
Optical constants of Ih, Ic, and amorphous HO ices in the THz and IR ranges
A. A. Gavdush, F. Ribeiro, M. K. Matveishina +9
Direct measurements of optical constants in the THz spectral region for astrophysically relevant HO ice samples are scarce. Extrapolation of optical properties in the THz spect…
Probing the ion-neutral drift velocity towards the L1544 prestellar core: Detection of ambipolar diffusion using ND and para-NHD
Doris Arzoumanian, Silvia Spezzano, Tommaso Grassi +9
The dynamical role of the magnetic field in the star formation process is tightly linked to the coupling between matter and the field. This coupling is due to the interaction betwe…
A 3D physico-chemical model of a pre-stellar core. II. Dynamic chemical evolution in a pre-stellar core model using tracer particles
S. S. Jensen, S. Spezzano, P. Caselli +3
This work explores the differences between static and dynamically evolving physico-chemical models of pre-stellar cores. A 3D MHD model of a pre-stellar core embedded in a dynamic…
A differentiable and optimizable 3D model for interpretation of observed spectral data cubes
T. Grassi, J. E. Pineda, S. Spezzano +6
Molecular spectral cubes of prestellar cores encode the information on the physical and chemical properties of these objects along the line of sight. To retrieve this information,…
Impact of cosmic-ray propagation on the chemistry and ionisation fraction of dark clouds
G. Latrille, A. Lupi, S. Bovino +3
A proper modelling of the cosmic-ray ionisation rate within gas clouds is crucial to describe their chemical evolution accurately. However, this modelling is computationally demand…
Mapping Synthetic Observations to Prestellar Core Models: An Interpretable Machine Learning Approach
T. Grassi, M. Padovani, D. Galli +6
Observations of molecular lines are a key tool to determine the main physical properties of prestellar cores. However, not all the information is retained in the observational proc…
Planet Formation and Disk Chemistry: Dust and Gas Evolution during Planet Formation
G. Perotti, L. Cacciapuoti, N. -D. Tung +3
Over the past decade, progress in observational capabilities, combined with theoretical advancements, have transformed our comprehension of the physics and chemistry during planet…
Testing analytical methods to derive the cosmic-ray ionisation rate in cold regions via synthetic observations
E. Redaelli, S. Bovino, A. Lupi +4
Cosmic rays (CRs) heavily impact the chemistry and physics of cold and dense star-forming regions. However, characterising their ionisation rate is still challenging from an observ…
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…
