Non-ideal MHD and protostellar feedback effects on disc formation and evolution in numerical simulations of star cluster formation
Nina Filippova, Stella S. R. Offner, Michael Y. Grudic +1
While recent surveys have resolved hundreds of nearby protostellar discs, numerical simulations assuming ideal magnetohydrodynamics (MHD) have historically struggled to achieve dis…
Gauging the Impact of Cosmic Ray Feedback on the Stellar Initial Mass Function
Margot Fitz Axen, Stella S. R. Offner, Philip F. Hopkins +1
Cosmic rays (CRs) drive ionization and influence gas dynamics in molecular clouds (MCs), potentially impacting the resulting star formation outcomes. Although previous simulations…
The Green Bank Ammonia Survey: Data Release 2
Jaime E. Pineda, Rachel K. Friesen, Erik Rosolowsky +22
We present an overview of the final data release (DR2) from the Green Bank Ammonia Survey (GAS). GAS is a Large Program at the Green Bank Telescope to map all Gould Belt star-formi…
First results from ALPPS: a sub-Alfvénic streamer in SVS13A
P. C. Cortes, J. E. Pineda, T. -H. Hsieh +22
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…
Modeling turbulent and self-gravitating fluids with Fourier neural operators
Keith Poletti, Stella S. R. Offner, Rachel A. Ward
Neural Operators (NOs) are a leading method for surrogate modeling of partial differential equations. Unlike traditional neural networks, which approximate individual functions, NO…
