SN 2021pfs: A Type Ia Supernova Likely Affected by Progenitor Metallicity, as Revealed by Comparison with Its Twin Counterpart

Abdusamatjan Iskandar, Xiaofeng Wang, Ali Esamdin +15

We present extensive photometric and spectroscopic observations of the normal type Ia supernovae (SNe Ia) 2021pfs, which occurred in the Seyfert 2 galaxy NGC 5427 at a redshift 0.0…

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…

Radiative Transfer Modeling of Stripped-envelope Supernovae II: Neural Network Emulation of Light Curves

S. Karthik Yadavalli, V. Ashley Villar, Maria R. Drout +3

We present the first neural-network emulator of stripped-envelope supernova (SESN) lightcurves, trained on a grid of 4499 light curves simulated with the radiative transfer (RT) co…

Electron correlation in semiconductors and insulators via symbolic regression

Nick Pant, Viet-Anh Ha, Donghwan Kim +1

Predicting quasiparticle energies in materials requires expensive numerical evaluations of the electron self-energy. This limits calculations to ordered systems with small unit cel…

Compass: Continuously Aligning Social Media Feeds via In-Situ Reflections

Aadit Barua, Leijie Wang, Amy X. Zhang

Social media recommendation feeds often optimize for users' immediate impulses rather than preferences they would hold after deeper reflection. Some systems address this misalignme…
