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…
The evolution of supermassive blackhole mass--bulge mass relation by a semi-analytic model, GC
Tatsuki Shimizu, Taira Oogi, Takashi Okamoto +2
We have investigated the redshift evolution of the relationship between supermassive black hole (SMBH) mass and host bulge mass using a semi-analytical galaxy formation model …
Cloud-cloud collisions triggering star formation in galaxy simulations
Shu Horie, Takashi Okamoto, Asao Habe
Cloud-cloud collisions (CCCs) are expected to compress gas and trigger star formation. However, it is not well understood how the collisions and the induced star formation affect g…
The impact of bar origin and morphology on stellar migration
Elizabeth J. Iles, Alex R. Pettitt, Takashi Okamoto +1
Different mechanisms driving bar structure formation indicate that bar origins should be distinguishable in the stellar populations of galaxies. To study how these origins affect d…
