To advance our understanding of dust properties in class 0/I young stellar objects, it is crucial to resolve their structures at multiple wavelengths and investigate how grain grow…
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,…
PRODIGE - envelope to disk with NOEMA: VII. (Complex) organic molecules in the NGC1333 IRAS4B1 outflow: A new laboratory for shock chemistry
Laura A. Busch, J. E. Pineda, P. Caselli +20
Shock chemistry is an excellent tool to shed light on the formation and destruction mechanisms of complex organic molecules (COMs). The L1157-mm outflow is the only low-mass protos…

We present the first results from the ALMA Perseus Polarization Survey (ALPPS), focusing on the magnetic field in the SVS13A circumbinary disk. The dataset includes full-Stokes dus…
Hunting pre-stellar cores with APEX: overview
P. Caselli, S. Spezzano, E. Redaelli +8
[Abridged] Pre-stellar cores are centrally concentrated starless cores on the verge of star formation and they represent the initial conditions for star and planet forma…
Cosmic-ray ionisation rate in low-mass cores: the role of the environment
E. Redaelli, S. Bovino, G. Sabatini +6
Context: Cosmic rays drive several key processes for the chemistry and dynamical evolution of star-forming regions. Their effect is quantified mainly by means of the cosmic-ray ion…
