Detection of Circumstellar Helium in Type Iax Progenitor Systems

Wynn Jacobson-Galan, Ryan Foley, Josiah Schwab +6

We present direct spectroscopic modeling of 44 Type Iax supernovae (SNe Iax) using spectral synthesis code SYNAPPS. We confirm detections of helium emission in the early-time spect…

Deep Learning of Quasar Spectra to Discover and Characterize Damped Lya Systems

David Parks, J. Xavier Prochaska, Shawfeng Dong +1

We have designed, developed, and applied a convolutional neural network (CNN) architecture using multi-task learning to search for and characterize strong HI Lya absorption in quas…

GPU-accelerated Gibbs sampling: a case study of the Horseshoe Probit model

Alexander Terenin, Shawfeng Dong, David Draper

Gibbs sampling is a widely used Markov chain Monte Carlo (MCMC) method for numerically approximating integrals of interest in Bayesian statistics and other mathematical sciences. M…

The Deflagration Stage of Chandrasekhar Mass Models For Type Ia Supernovae: I. Early Evolution

C. M. Malone, A. Nonaka, S. E. Woosley +4

We present high-resolution, full-star simulations of the post-ignition phase of Type Ia supernovae using the compressible hydrodynamics code Castro. Initial conditions, including t…

Burning Thermals in Type Ia Supernovae

A J Aspden, J B Bell, S Dong +1

We develop a one-dimensional theoretical model for thermals burning in Type Ia supernovae based on the entrainment assumption of Morton, Taylor and Turner. Extensions of the standa…

Star Formation and Feedback in Dwarf Galaxies

Shawfeng Dong, D. N. C. Lin, S. D. Murray

We examine the star formation history and stellar feedback effects of dwarf galaxies under the influence of extragalactic ultraviolet radiation. We consider the dynamical evolution…
