Gauging the Impact of Cosmic Ray Feedback on the Stellar Initial Mass Function
Margot Fitz Axen, Stella S. R. Offner, Philip F. Hopkins +1
Cosmic rays (CRs) drive ionization and influence gas dynamics in molecular clouds (MCs), potentially impacting the resulting star formation outcomes. Although previous simulations…
Connection between galaxy morphology and dark-matter halo structure II: predicting disk structure from dark-matter halo properties
Jinning Liang, Fangzhou Jiang, Houjun Mo +4
We investigate how galactic disk structures connect to the detailed properties of their host dark-matter halos using the TNG50 simulation. From the hydrodynamic and matched dark-ma…
Connection between galaxy morphology and dark-matter halo structure I: a running threshold for thin discs and size predictors from the dark sector
Jinning Liang, Fangzhou Jiang, Houjun Mo +5
We study the connection between galaxy morphology and host dark matter (DM) halo structure using cosmological simulations. Introducing a new kinematic decomposition scheme, we robu…
Bridging Scales: Coupling the galactic nucleus to the larger cosmic environment
Kung-Yi Su, Priyamvada Natarajan, Hyerin Cho +4
Coupling black hole (BH) feeding and feedback involves interactions across vast spatial and temporal scales that is computationally challenging. Tracking gas inflows and outflows f…
Suppressed Cosmic Ray Energy Densities in Molecular Clouds From Streaming Instability-Regulated Transport
Margot Fitz Axen, Stella Offner, Phillip F. Hopkins +2
Cosmic rays (CRs) are the primary driver of ionization in star forming molecular clouds (MCs). Despite their potential impacts on gas dynamics and chemistry, no simulations of star…
