Turbulence inference from CO spectral observations
Jayashree Narayan, Aris Tritsis, Christoph Federrath
Turbulence influences the structure and dynamics of molecular clouds, and plays a key role in regulating star formation. We therefore need methods to accurately infer turbulence pr…
Investigating the role of magnetic fields in the formation and evolution of striations in interstellar clouds with PRIMA
Raphael Skalidis, Konstantinos Tassis, Aris Tritsis +1
Striations are diffuse, linear, quasi-periodic, and magnetized structures located in the outskirts of molecular clouds. These structures seem to play an important role during the e…
Ambipolar diffusion and the mass-to-flux ratio in a turbulent collapsing cloud
Aris Tritsis
The formation of stars is governed by the intricate interplay of nonideal magnetohydrodynamic (MHD) effects, gravity, and turbulence. Computational challenges have hindered a compr…
A three-step approach to reliably estimate magnetic field strengths in star-forming regions
Aristeidis Polychronakis, Aris Tritsis, Raphael Skalidis +1
The magnetic field is known to play a crucial role in star formation. Dust polarization is an effective tool for probing the morphology of the field, yet it does not directly trace…
Projection-angle effects when "observing" a turbulent magnetized collapsing molecular cloud. II. Magnetic field
A. Tritsis, S. Basu, C. Federrath
Interstellar magnetic fields are thought to play a fundamental role in the evolution of star-forming regions. Polarized thermal dust emission serves as a key probe for understandin…
A fast and robust recipe for modeling non-ideal MHD effects in star-formation simulations
E. Agianoglou, A. Tritsis, K. Tassis
Non-ideal MHD effects are thought to be a crucial component of the star-formation process. Numerically, several complications render the study of non-ideal MHD effects in 3D simula…
