A Multiwavelength Inventory for the Local Group L-band Survey I: Atlas and Radial Profiles of Local Group Galaxies
Cosima Eibensteiner, Adam K. Leroy, Jiayi Sun +21
Resolving atomic gas at pc physical resolution is currently feasible only for the very nearest galaxies. We combine 120 pc resolution HI data using the Karl G. Jansky…
Pressure-regulated feedback-modulated star formation as a subgrid model for galaxy formation simulations
Sarah M. R. Jeffreson, Eve C. Ostriker, Chang-Goo Kim +1
We present a new subgrid model for interstellar gas evolution in cosmological simulations of galaxy formation, based on the pressure-regulated, feedback-modulated (PRFM) theory of…
Learning the Universe with PRFM-vol: Introducing a new subgrid model for star formation in cosmological simulations
Jan D. Burger, Volker Springel, Eve C. Ostriker +7
We introduce PRFM-vol, a new subgrid model for star formation in cosmological simulations that aims to increase the physical realism of cosmological simulations by leveraging resul…
Cosmic Ray Feedback in Galactic Disks: Star Formation, Cosmic Ray Transport, and Multiphase Outflows in TIGRESS++ Simulations
Chang-Goo Kim, Lucia Armillotta, Eve C. Ostriker +5
We present new simulations of local star-forming disks that self-consistently evolve cosmic rays (CRs) and multiphase gas using TIGRESS++. To isolate the role of CRs, we conduct pa…
Interstellar Medium-Driven Orbital Transport -- I. Radial Heating and Migration
Shaunak Modak, Chris Hamilton, Eve C. Ostriker +1
Interstellar medium (ISM) structures gravitationally perturb stellar orbits in galactic disks, driving orbital heating and migration. However, studies of these transport processes…
Stellar associations powering HII regions $\unicode{x2013}$ II. Escape fraction of ionizing photons
Fabian Scheuermann, Kathryn Kreckel, Jia Wei Teh +27
Newly formed stars have a profound impact on their environment by depositing energy and momentum into the surrounding gas. However, only a fraction of the stellar feedback is retai…
