High Resolution Grid-based Simulations of the Warm-Hot Intergalactic Medium
Lile Wang, Renyue Cen
We present high-resolution cosmological hydrodynamic simulations of the Warm-Hot Intergalactic Medium (WHIM) using the GPU-optimized grid-based hydrodynamic code Kratos. Employing…
From Inspiral to Expansion: The Wake-Driven Torque on Binary Black Holes in Gaseous Medium
Jixuan Yang, Lile Wang, Xinyu Li +1
Binary black holes (BBHs) in gaseous medium, such as active galactic nucleus (AGN) disks, are important gravitational-wave sources, yet the gas-driven torque that governs their orb…
HOTDISK. Finding Massive Protostellar Disks with Water and Refractory Molecular Species
Kai Yang, Yichen Zhang, Kei E. I. Tanaka +16
We present high-angular-resolution (, au) ALMA Band~6 observations from the HOTDISK project (Hot-Origin Tracer survey of DISKs of massive pro…
The effects of star-gas interactions on binary evolution in open clusters
Jixuan Yang, Lile Wang, Xinyu Li +3
Star-gas interactions can provide gravitational feedback that influences the dynamical evolution of stellar clusters, through processes such as dynamical friction (DF) and its non-…
Consistent Modeling of Non-equilibrium Dust Sublimation and the Interactions with Dust Evolution in the Inner Regions of Protoplanetary Disks
Sheng Xu, Lile Wang, Luis C. Ho +2
The inner regions of protoplanetary disks are host to the sublimation of dust grains, a process traditionally modeled using equilibrium thermodynamics. We demonstrate through ab-in…
AGN star dynamics under the Influence of Outflow-Ambient Interactions
Muxin Liu, Lile Wang, Peng Peng
Stars with outflows interacting with ambient gas experience accelerations arising from the gravitational feedback induced by the interaction structure. In this work, three-dimensio…
Disturbed cold gas in galaxy and structure formation
Siwei Zou, Robert A. Simcoe, Patrick Petitjean +18
Cold and cool gas (T K) in the circumgalactic medium (CGM) and its interaction with galaxies remain poorly understood. Simulations predict that cold gas flows into gala…
Turbulent Diffuse Molecular Media with Non-ideal Magnetohydrodynamics and Consistent Thermochemistry: Numerical Simulations and Dynamic Characteristics
Nannan Yue, Lile Wang, Thomas Bisbas +2
Turbulent diffuse molecular clouds can exhibit complicated morphologies caused by the interactions among radiation, chemistry, fluids, and fields. We performed full 3D simulations…
Cloud Crushing and Dissipation of Uniformly-Driven Adiabatic Turbulence in Circumgalactic Media
Alex Lv, Lile Wang, Renyue Cen +1
The circumgalactic medium (CGM) is responsive to kinetic disruptions generated by nearby astrophysical events. In this work, we study the saturation and dissipation of turbulent hy…
FEASTS Combined with Interferometry (I): Overall Properties of Diffuse HI and Implications for Gas Accretion in Nearby Galaxies
Jing Wang, Xuchen Lin, Dong Yang +19
We present a statistical study of the properties of diffuse HI in ten nearby galaxies, comparing the HI detected by the single-dish telescope FAST (FEASTS program) and the interfer…
Open Cluster Dynamics under the Influence of Outflow-Ambient Interactions
Muxin Liu, Lile Wang, Xiaoting Fu +1
Stars with outflows impinging on ambient gas experience accelerations due to the gravitational feedback from the interaction morphology between the outflow and the ambient gas. Suc…
