The AGORA High-resolution Galaxy Simulations Comparison Project. V. Satellite Galaxy Populations in a Cosmological Zoom-in Simulation of a Milky Way-Mass Halo
Yves Revaz, Loïc Hausammann, Alessandro Lupi
We analyze and compare the satellite halo populations at z similar to 2 in the high-resolution cosmological zoom-in simulations of a 1012 M circle dot target halo (z = 0 mass) carried out on eight widely used astrophysical simulation codes (Art-I, Enzo, Ra ...
Bristol2024Hydrodynamical simulations of merging galaxy clusters: giant dark matter particle colliders, powered by gravity
David Richard Harvey, Richard Massey
Terrestrial particle accelerators collide charged particles, then watch the trajectory of outgoing debris - but they cannot manipulate dark matter. Fortunately, dark matter is the main component of galaxy clusters, which are continuously pulled together by ...
Oxford Univ Press2024COSMOS-Web: An Overview of the JWST Cosmic Origins Survey
Michaela Hirschmann, Richard Massey
We present the survey design, implementation, and outlook for COSMOS-Web, a 255 hr treasury program conducted by the James Webb Space Telescope in its first cycle of observations. COSMOS-Web is a contiguous 0.54 deg² NIRCam imaging survey in four filters ( ...
IOP Publishing Ltd2023The evolution of the Milky Way's thin disc radial metallicity gradient with K2 asteroseismic ages
The radial metallicity distribution of the Milky Way's disc is an important observational constraint for models of the formation and evolution of our Galaxy. It informs our understanding of the chemical enrichment of the Galactic disc and the dynamical pro ...
