     “Wave dark matter”

    A dark matter particle lighter than about 30 eV exhibits wave-like behavior in a typical galactic environment. We will discuss the particle physics motivations for such a light particle, in particular an axion or axion-like-particle. We will review the wave dynamics and phenomenology, and discuss the implications for astrophysical observations as well as experimental detection.

    "Redefining the Standard for 1D Stellar Modeling"


    One-dimensional stellar structure and evolution models are the foundation upon which our chains of inference regarding all manner of cosmological phenomena are built. Questions regarding the enrichment of the interstellar medium, the initial mass functions of galaxies, the frequency of supernovae, the formation mechanisms of planetary systems, the origins of heavy elements and life, and the value of the Hubble constant cannot be answered without...

    "Comparing star formation in TNG50 (SH03) with the Pressure-Regulated, Feedback-Modulated (PRFM) Equilibrium Model"


    Traditional star formation sub-grid models, such as the Springel and Hernquist (2003, SH03), implemented on cosmological galaxy formation simulations, usually employ phenomenological adjustable parameters to reproduce certain key observables such as the Kennicutt-Schmidt empirical relation. Calibrated to a suite of multiphase magnetohydrodynamic simulations run with the TIGRESS computational framework, Ostriker and Kim (2022) have recently presented the...

    "Dynamical Instabilities in the Aid of Planet Formation in Circumstellar Disks"

    Abstract: During the first million years of evolution, nascent planetary systems are embedded in dense disk-shaped clouds of gas. These circumstellar disks are home to a myriad of hydrodynamical processes, which bring about turbulence and the emergence of viscous-like behavior, enabling accretion of gas onto the protostar. Meanwhile, micron-sized dust grains embedded in the disk are growing through coagulation onto pebbles and rocks. Turbulence has a positive effect on these small solids,...
