Resolving the Dust Budget Crisis at with Optically Thick, High-Density Molecular Clumps: MACS0416_Y1
Ryusei R. Kano, Tsutomu T. Takeuchi, Erina R. Kawamoto +3
Dust plays a crucial role in galaxy evolution by shaping the spectral energy distribution (SED) and star formation history. However, standard models often underestimate the infrare…
A new galaxy spectral energy distribution model consistent with the evolution of dust
Kazuki Y. Nishida, Tsutomu T. Takeuchi, Takuma Nagata +1
The spectral energy distribution (SED) of galaxies provides fundamental information on the related physical processes. However, the SED is significantly affected by dust in its int…
Detection of the Far-infrared [O III] and Dust Emission in a Galaxy at Redshift 8.312: Early Metal Enrichment in the Heart of the Reionization Era
Yoichi Tamura, Ken Mawatari, Takuya Hashimoto +19
We present the Atacama Large Millimeter/submillimeter Array (ALMA) detection of the [O III] 88 m line and rest-frame 90 m dust continuum emission in a Y-dropout Lyman break g…
Revisiting the lifetime estimate of large presolar grains in the interstellar medium
Hiroyuki Hirashita, Takaya Nozawa, Ryosuke S. Asano +1
Some very large (>0.1 um) presolar grains are sampled in meteorites. We reconsider the lifetime of very large grains (VLGs) in the interstellar medium focusing on interstellar shat…
Evolution of grain size distribution in high-redshift dusty quasars: Integrating large amounts of dust and unusual extinction curves
Takaya Nozawa, Ryosuke S. Asano, Hiroyuki Hirashita +1
The discoveries of huge amounts of dust and unusual extinction curves in high-redshift quasars (z > 4) cast challenging issues on the origin and properties of dust in the early uni…
Evolution of the extinction curves in galaxies
Ryosuke S. Asano, Tsutomu T. Takeuchi, Hiroyuki Hirashita +1
We investigate the evolution of extinction curves in galaxies based on our evolution model of grain size distribution. In this model, we considered various processes: dust formatio…
Dense molecular cloud cores as a source of micrometer-sized grains in galaxies
Hiroyuki Hirashita, Ryosuke S. Asano, Takaya Nozawa +2
Coreshine in dense molecular cloud cores (dense cores) is interpreted as evidence for micrometer-sized grains (referred to as very large grains, VLGs). VLGs may have a significant…
Formation History of Polycyclic Aromatic Hydrocarbons in Galaxies
Ji Yeon Seok, Hiroyuki Hirashita, Ryosuke S. Asano
Polycyclic aromatic hydrocarbons (PAHs) are some of the major dust components in the interstellar medium (ISM). We present our evolution models for the abundance of PAHs in the ISM…
Gas-to-Dust mass ratios in local galaxies over a 2 dex metallicity range
A. Rémy-Ruyer, S. C. Madden, F. Galliano +17
This paper analyses the behaviour of the gas-to-dust mass ratio (G/D) of local Universe galaxies over a large metallicity range. We combine three samples: the Dwarf Galaxy Survey,…
What determines the grain size distribution in galaxies?
Ryosuke S. Asano, Tsutomu T. Takeuchi, Hiroyuki Hirashita +1
We construct a dust evolution model taking into account the grain size distribution, and investigate what kind of dust processes determine the grain size distribution at each stage…
Dust formation history of galaxies: a critical role of metallicity for the dust mass growth by accreting materials in the interstellar medium
Ryosuke S. Asano, Tsutomu T. Takeuchi, Hiroyuki Hirashita +1
This paper investigate what is the main driver of the dust mass growth in the interstellar medium (ISM) by using a chemical evolution model of galaxy with metals (elements heavier…
