A warm ultra-luminous infrared galaxy just 600 million years after the Big Bang
T. J. L. C. Bakx, Laura Sommovigo, Yoichi Tamura +24
We present an Atacama Large Millimeter/submillimeter Array (ALMA) Band 9 continuum detection () of MACS0416_Y1 that confirms the suspected warm dust (91 K) of…
The First Star-by-star -body/Hydrodynamics Simulation of Our Galaxy Coupling with a Surrogate Model
Keiya Hirashima, Michiko S. Fujii, Takayuki R. Saitoh +9
A major goal of computational astrophysics is to simulate the Milky Way Galaxy with sufficient resolution down to individual stars. However, the scaling fails due to some small-sca…
The origin of the metallicity difference between star-forming and passive galaxies: Insights from ν2GC semi-analytic model
Qiansheng Liu, Takashi Okamoto, Taira Oogi +1
We investigate the origin of the observed metallicity difference between star-forming and passive galaxies using the semi-analytic galaxy formation model nu2GC. Our fiducial model…
Comparison of simulations and semi-analytical model for WDM subhalo mass functions
Mizuki Ono, Takashi Okamoto, Shin'ichiro Ando +1
The Cold Dark Matter (CDM) model successfully explains large-scale structure formation, but challenges remain at smaller scales, leading to interest in Warm Dark Matter (WDM) as an…
