Magnetic field evolution in feedback-dominated galaxies
Yue Samuel Lu, Dušan Kereš, Philip F. Hopkins +1
Over the last decade, magnetic fields (B-fields) have become a common ingredient in galaxy formation simulations. Although seemingly unimportant in matching observational constrain…
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…
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…
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…
Constrain the Dark Matter Distribution of Ultra-diffuse Galaxies with Globular-Cluster Mass Segregation: A Case Study with NGC5846-UDG1
Jinning Liang, Fangzhou Jiang, Shany Danieli +2
The properties of globular clusters (GCs) contain valuable information of their host galaxies and dark-matter halos. In the remarkable example of ultra-diffuse galaxy, NGC5846-UDG1…
Effects of Different Cosmic Ray Transport Models on Galaxy Formation
Philip F. Hopkins, T. K. Chan, Jonathan Squire +4
Cosmic rays (CRs) with ~GeV energies can contribute significantly to the energy and pressure budget in the interstellar, circumgalactic, and intergalactic medium (ISM, CGM, IGM). R…
Low-Redshift Lyman Limit Systems as Diagnostics of Cosmological Inflows and Outflows
Z. Hafen, C. -A. Faucher-Giguere, D. Angles-Alcazar +6
We use cosmological hydrodynamic simulations with stellar feedback from the FIRE project to study the physical nature of Lyman limit systems (LLSs) at z<1. At these low redshifts,…
A Stellar Feedback Origin for Neutral Hydrogen in High-Redshift Quasar-Mass Halos
C. -A. Faucher-Giguere, R. Feldmann, E. Quataert +3
Observations reveal that quasar host halos at z~2 have large covering fractions of cool dense gas (>~60% for Lyman limit systems within a projected virial radius). Most simulations…
The Impact of Baryonic Physics on the Structure of Dark Matter Halos: the View from the FIRE Cosmological Simulations
T. K. Chan, D. Kereš, J. Oñorbe +4
We study the distribution of cold dark matter (CDM) in cosmological simulations from the FIRE (Feedback In Realistic Environments) project, for g…
Neutral hydrogen in galaxy halos at the peak of the cosmic star formation history
C. -A. Faucher-Giguere, P. F. Hopkins, D. Keres +3
We use high-resolution cosmological zoom-in simulations from the FIRE project to make predictions for the covering fractions of neutral hydrogen around galaxies at z=2-4. These sim…
CANDELS: The progenitors of compact quiescent galaxies at z~2
Guillermo Barro, S. M. Faber, Pablo G. Perez-Gonzalez +29
We combine high-resolution HST/WFC3 images with multi-wavelength photometry to track the evolution of structure and activity of massive (log(M*) > 10) galaxies at redshifts z = 1.4…
