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…
Binding Energy Evaluation Platform: A database of quantum chemical binding energy distributions for the astrochemical community
Giulia M. Bovolenta, Stefan Vogt-Geisse, Stefano Bovino +1
The quality of astrochemical models is highly dependent on reliable binding energy (BE) values that consider the morphological and energetic variety of binding sites on the surface…
Reducing the complexity of chemical networks via interpretable autoencoders
T. Grassi, F. Nauman, J. P. Ramsey +3
In many astrophysical applications, the cost of solving a chemical network represented by a system of ordinary differential equations (ODEs) grows significantly with the size of th…
Chemical complexity in astrophysical simulations: optimization and reduction techniques
T. Grassi, S. Bovino, D. Schleicher +1
Chemistry has a key role in the evolution of the interstellar medium (ISM), so it is highly desirable to follow its evolution in numerical simulations. However, it may easily domin…
Complexity reduction of astrochemical networks
T. Grassi, S. Bovino, F. A. Gianturco +2
We present a new computational scheme aimed at reducing the complexity of the chemical networks in astrophysical models, one which is shown to markedly improve their computational…
