Modeling Long-Wavelength Amorphous Dust Emission Based on the Physically Motivated Soft-Potential Model
Masashi Nashimoto
We propose a new amorphous dust emission model based on the soft-potential (SP) model, applicable in the long-wavelength range from the far-infrared to the microwave. The SP model…
Cosmic very small dust grains as a natural laboratory of mesoscopic physics: Modeling thermal and optical properties of graphite grains
Kenji Amazaki, Masashi Nashimoto, Makoto Hattori
Cosmic very small dust grains (VSGs) contain 100 to 10,000 atoms, making it a mesoscopic system with specific thermal and optical characteristics due to the finite number of atoms…
Mitigating Cosmic Microwave Background Shadow Degradation of Tensor-to-scalar Ratio Measurements through Map-based Studies
Tamaki Murokoshi, Yuji Chinone, Masashi Nashimoto +2
It has been pointed out that the spurious Cosmic Microwave Background (CMB) B-mode polarization signals caused by the absorption of the CMB monopole component due to the Galactic i…
The Missing Satellite Problem Outside of the Local Group. II. Statistical Properties of Satellites of Milky Way-like Galaxies
Masashi Nashimoto, Masayuki Tanaka, Masashi Chiba +3
We present a new observation of satellite galaxies around seven Milky Way (MW)-like galaxies located outside of the Local Group (LG) using Subaru/Hyper Suprime-Cam imaging data to…
Cosmic Amorphous Dust Model as the Origin of Anomalous Microwave Emission
Masashi Nashimoto, Makoto Hattor, Frederick Poidevin +1
We have shown that the thermal emission of the amorphous dust composed of amorphous silicate dust (a-Si) and amorphous carbon dust (a-C) provides excellent fit both to the observed…
CMB Shadows: The Effect of Interstellar Extinction on Cosmic Microwave Background Polarization and Temperature Anisotropy
Masashi Nashimoto, Makoto Hattori, Yuji Chinone
We evaluate the degradation of the accuracy of the component separation between the cosmic microwave background (CMB) and foreground components caused by neglect of absorption of t…
Thermal emission from the amorphous dust: An alternative possibility of the origin of the anomalous microwave emission
Masashi Nashimoto, Makoto Hattori, Ricardo Génova-Santos +1
Complete studies of the radiative processes of thermal emission from the amorphous dust from microwave through far infrared wavebands are presented by taking into account, self-con…
