Grain-size evolution and rapid dust growth in high-redshift galaxies
Daisuke Toyouchi, Andrea Ferrara, Yurina Nakazato +3
We present a galaxy evolution model that incorporates grain-size evolution in a multiphase interstellar medium (ISM) to investigate dust attenuation in galaxies at . Our…
Dust enrichment from core-collapse supernovae and extinction curves in the high-redshift universe
Koki Otaki, Raffaella Schneider, Simone Bianchi +4
Recent JWST observations have revealed that some galaxies at generally exhibit relatively flat ultraviolet (UV) attenuation curves and a weak UV bump. These features…
Collision frequency between dark matter subhaloes within Milky Way-like galaxies
Koki Otaki, Yudai Kazuno, Masao Mori
In the standard cold dark matter (CDM) model, sub-galactic structures hierarchically collide and merge to build up larger structures. Mergers and collisions between dwarf galaxies…
Effective supernova dust yields from rotating and non-rotating stellar progenitors
Koki Otaki, Raffaella Schneider, Luca Graziani +4
Supernovae (SNe) are believed to be the dominant sources of dust production at high redshift. However, the reverse shock generated by the interaction of the SN forward shock and th…
Cosmological evolution of dark matter subhaloes under tidal stripping by growing Milky Way-like galaxies
Yudai Kazuno, Masao Mori, Yuka Kaneda +1
We present the findings of a comprehensive and detailed analysis of merger tree data from ultra-high-resolution cosmological -body simulations. The analysis, conducted with a pa…
