Simulations of Dust Content and Attenuation in Galaxies
Dhruv T. Zimmerman, Jed McKinney, Desika Narayanan +10
Correctly modeling the dust attenuation law in galaxies is essential to properly inferring their growth and physical properties. With the rapid discovery of galaxies by JWST…
AGN-driven outflows in dwarf galaxies from cosmological simulations: Internal properties and observational signatures
Elena Arjona-Gálvez, Arianna Di Cintio, Robert J. J. Grand +4
While AGN feedback is a key driver of massive galaxy evolution, its physical properties and observational signatures in the dwarf regime remain poorly understood. We investigate th…
The Lifecycle and Emission Properties of PAHs in Cosmological Hydrodynamic Galaxy Formation Simulations
Desika Narayanan, Paul Torrey, Massimiliano Parente +16
We present the first cosmological model for the lifecycle and luminous properties of PAHs in galaxies as they evolve from z=6-->0. We model 40 zoom-in galaxies, coupled with an on-…
SMUGGLE-Ring: Evolutionary link between nuclear star cluster and nuclear disk
SungWon Kwak, Mathias Schultheis, Ivan Minchev +8
We present a high-resolution hydrodynamical simulation of the formation and evolution of nuclear structures in a Milky Way-mass galaxy using the SMUGGLE model. The system naturally…
The SMUGGLE-Ring project: Bar and bulge effects on nuclear disk and ring formation
SungWon Kwak, Federico Marinacci, Matthias Steinmetz +8
We present the first results from the SMUGGLE-Ring project, a suite of simulations employing the SMUGGLE ISM and stellar feedback model to explore nuclear structures in Milky Way-m…
AGN feedback in merging galaxies with a SMUGGLE multiphase ISM
Aneesh Sivasankaran, Laura Blecha, Paul Torrey +6
We study fast nuclear winds driven by Active Galactic Nucleus (AGN) feedback in merging galaxies using high-resolution hydrodynamics simulations. We use Stars and MUltiphase Gas in…
The Entangling of Supernova Feedback Impacts with Coarsening Simulation Resolution
Eric Zhang, Laura V. Sales, Thales A. Gutcke +11
It is often understood that supernova (SN) feedback in galaxies is responsible for regulating star formation (SF) and generating gaseous outflows. However, a detailed look at the s…
Tracing the Origins of Hot Halo Gas in Milky Way-Type Galaxies with SMUGGLE
Zhijie Zhang, Xiaoxia Zhang, Hui Li +8
Current galaxy formation models predict the existence of X-ray-emitting gaseous halos around Milky Way (MW)-type galaxies. To investigate properties of this coronal gas in MW-like…
The Growth of Dust in Galaxies in the First Billion Years with Applications to Blue Monsters
Desika Narayanan, Paul Torrey, Daniel Stark +9
A combination of JWST observations at z~12-14 and ALMA observations of extremely dust-rich systems at z~6 has demonstrated that dust grows extremely fast in the early Universe, wit…
Understanding the Baryon Cycle: Fueling Star Formation via Inflows in Milky Way-like Galaxies
Filippo Barbani, Raffaele Pascale, Federico Marinacci +4
Galaxies are not isolated systems; they continuously interact with their surroundings by ejecting gas via stellar feedback and accreting gas from the environment. Understanding the…
The life cycle of giant molecular clouds in simulated Milky Way-mass galaxies
Yang Ni, Hui Li, Mark Vogelsberger +3
In this work, we trace the complete life cycle of individual GMCs in high-resolution Milky Way-mass galaxy simulations to determine how different stellar feedback mechanisms and ga…
The Ultraviolet Slopes of Early Universe Galaxies: The Impact of Bursty Star Formation, Dust, and Nebular Continuum Emission
Desika Narayanan, Daniel P. Stark, Steven L. Finkelstein +8
JWST has enabled the detection of the UV continuum of galaxies at z>10, evidencing a population of extremely blue, potentially dust-free galaxies. Interpreting the UV spectra of ga…
Large dark matter content and steep metallicity profile predicted for Ultra-Diffuse Galaxies formed in high-spin halos
José A. Benavides, Laura V. Sales, Mario. G. Abadi +3
We study the stellar properties of a sample of simulated ultra-diffuse galaxies (UDGs) with stellar mass , selected from the TNG50 simul…
Bursty Star Formation in Dwarfs is Sensitive to Numerical Choices in Supernova Feedback Models
Eric Zhang, Laura V. Sales, Federico Marinacci +6
Simulations of galaxy formation are mostly unable to resolve the energy-conserving phase of individual supernova events, having to resort to subgrid models to distribute the energy…
Evolution and distribution of superbubbles in simulated Milky Way-like galaxies
Chengzhe Li, Hui Li, Wei Cui +4
Stellar feedback plays a crucial role in regulating baryon cycles of a galactic ecosystem, and may manifest itself in the formation of superbubbles in the interstellar medium. In t…
AGN feedback in isolated galaxies with a SMUGGLE multiphase ISM
Aneesh Sivasankaran, Laura Blecha, Paul Torrey +6
Feedback from active galactic nuclei (AGN) can strongly impact the host galaxies by driving high-velocity winds that impart substantial energy and momentum to the interstellar medi…
Low- and High-velocity \ion{O}{6} in Milky Way-like Galaxies: the Role of Stellar Feedback
Zhijie Zhang, Xiaoxia Zhang, Hui Li +7
