The diversity and variability of star formation histories in models of galaxy evolution
(2020-07-25)
Understanding the variability of galaxy star formation histories (SFHs) across a range of time-scales provides insight into the
underlying physical processes that regulate star formation within galaxies. We compile the ...
The origin of the dust extinction curve in milky way-like galaxies
(Oxford University Press, 2021)
We develop a cosmological model for the evolution of dust grains in galaxies with a distribution of sizes in order to understand the origin of the Milky Way dust extinction curve. Our model considers the formation of active ...
The origin and evolution of Lyα blobs in cosmological galaxy formation simulations
(IOP Publishing Ltd, 2021)
High-redshift Lyα blobs (LABs) are an enigmatic class of objects that have been the subject of numerous observational and theoretical investigations. It is of particular interest to determine the dominant power sources for ...
Galaxy cold gas contents in modern cosmological hydrodynamic simulations
(Oxford University Press, 2020-07-03)
We present a comparison of galaxy atomic and molecular gas properties in three recent cosmological hydrodynamic simulations,
namely SIMBA, EAGLE, and IllustrisTNG, versus observations from z ∼ 0 to 2. These simulations ...
X-ray emission from hot gas in galaxy groups and clusters in SIMBA
(Oxford University Press, 2020-08-31)
We examine X-ray scaling relations for massive haloes (M500 > 1012.3 M) in the SIMBA galaxy formation simulation. The X-ray
luminosity, LX versus M500 has power-law slopes ≈5
3 and ≈8
3 above and below 1013.5 M, deviating ...
Breaking baryon-cosmology degeneracy with the electron density power spectrum
(IOP Publishing, 2022)
Uncertain feedback processes in galaxies affect the distribution of matter, currently limiting the power of weak lensing surveys. If we can identify cosmological statistics
that are robust against these uncertainties, or ...
Finding universal relations in Subhalo properties with artificial intelligence
(The Astrophysical Journal, 2022)
We use a generic formalism designed to search for relations in high-dimensional spaces to determine if the total mass of a subhalo can be predicted from other internal properties such as velocity dispersion, radius, or ...
Ceers key paper. I. An early look into the first 500myr of galaxy formation with jwst
(American Astronomical Society, 2023)
We present an investigation into the first 500 Myr of galaxy evolution from the Cosmic Evolution Early Release
Science (CEERS) survey. CEERS, one of 13 JWST ERS programs, targets galaxy formation from z ∼ 0.5 to >10
using ...
Efficient long-range active galactic nuclei (agns) feedback affects the low-redshift lyα forest
(American Astronomical Society, 2023)
Active galactic nuclei (AGNs) feedback models are generally calibrated to reproduce galaxy observables such as
the stellar mass function and the bimodality in galaxy colors. We use variations of the AGN feedback
implementations ...
Boundless baryons: how diffuse gas contributes to anisotropic tSZ signal around simulated three hundred clusters
(Oxford University Press, 2023)
Upcoming advances in galaxy surveys and cosmic microwave background data will enable measurements of the anisotropic distribution of diffuse gas in filaments and superclusters at redshift z = 1 and beyond, observed through ...
