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…
Prestellar Cores in Turbulent Clouds: Observational Perspectives on Structure, Kinematics, and Lifetime
Sanghyuk Moon, Eve C. Ostriker
We analyze an ensemble of simulated prestellar cores to facilitate interpretation of structure, kinematics, and lifetime of observed cores. While our theory predicts a "characteris…
Prestellar Cores in Turbulent Clouds: Properties of Critical Cores
Sanghyuk Moon, Eve C. Ostriker
A fraction of the dense cores within a turbulent molecular cloud will eventually collapse to form stars. Identifying the physical criteria for instability and analyzing critical co…
Prestellar Cores in Turbulent Clouds: Numerical Modeling and Evolution to Collapse
Sanghyuk Moon, Eve C. Ostriker
A fundamental issue in star formation is understanding the precise mechanisms leading to the formation of prestellar cores, and their subsequent gravitationally unstable evolution.…
Theory of Turbulent Equilibrium Spheres with Power-Law Linewidth-Size Relation
Sanghyuk Moon, Eve C. Ostriker
Dense cores inherit turbulent motions from the interstellar medium in which they form. As a tool for comparison to both simulations and observations, it is valuable to construct th…
Effects of Magnetic Fields on Gas Dynamics and Star Formation in Nuclear Rings
Sanghyuk Moon, Woong-Tae Kim, Chang-Goo Kim +1
Nuclear rings at the centers of barred galaxies are known to be strongly magnetized. To explore the effects of magnetic fields on star formation in these rings and nuclear gas flow…
Effects of Varying Mass Inflows on Star Formation in Nuclear Rings of Barred Galaxies
Sanghyuk Moon, Woong-Tae Kim, Chang-Goo Kim +1
Observations indicate that the star formation rate (SFR) of nuclear rings varies considerably with time and is sometimes asymmetric rather than being uniform across a ring. To unde…
Star Formation in Nuclear Rings with the TIGRESS Framework
Sanghyuk Moon, Woong-Tae Kim, Chang-Goo Kim +1
Nuclear rings are sites of intense star formation at the centers of barred galaxies. To understand what determines the structure and star formation rate (SFR; ) o…
A Fast Poisson Solver of Second-Order Accuracy for Isolated Systems in Three-Dimensional Cartesian and Cylindrical Coordinates
Sanghyuk Moon, Woong-Tae Kim, Eve C. Ostriker
We present an accurate and efficient method to calculate the gravitational potential of an isolated system in three-dimensional Cartesian and cylindrical coordinates subject to vac…
Equilibrium Sequences and Gravitational Instability of Rotating Isothermal Rings
Woong-Tae Kim, Sanghyuk Moon
Nuclear rings at centers of barred galaxies exhibit strong star formation activities. They are thought to undergo gravitational instability when sufficiently massive. We approximat…
