Low-energy C continuum states in three- model
Souichi Ishikawa
The electric multipole strength distributions for transitions from the ground state to (, , , and ) continuum states are studied…
Environment of SDSS quasars at explored by Subaru HSC
Kohei Shibata, Tohru Nagao, Hisakazu Uchiyama +5
The relationship between quasars and their galaxy environment is important for understanding the evolution of galaxies and supermassive black holes, but it is not fully understood.…
Algorithm Unrolling-based Denoising of Multimodal Graph Signals
Hayate Kojima, Keigo Takanami, Junya Hara +4
We propose a denoising method for multimodal graph signals by an alternating minimization scheme that sequentially solves signal restoration and graph learning problems. Many compl…
SILVIA: Ultra-precision formation flying demonstration for space-based interferometry
Takahiro Ito, Kiwamu Izumi, Isao Kawano +26
We propose SILVIA (Space Interferometer Laboratory Voyaging towards Innovative Applications), a mission concept designed to demonstrate ultra-precision formation flying between thr…
Initial acquisition requirements for optical cavities in the space gravitational wave antennae DECIGO and B-DECIGO
Yuta Michimura, Koji Nagano, Kentaro Komori +8
DECIGO (DECi-hertz Interferometer Gravitational Wave Observatory) is a space-based gravitational wave antenna concept targeting the 0.1-10 Hz band. It consists of three spacecraft…
DES to HSC: Detecting low surface brightness galaxies in the Abell 194 cluster using transfer learning
H. Thuruthipilly, Junais, J. Koda +7
Low surface brightness galaxies (LSBGs) are important for understanding galaxy evolution and cosmological models. The upcoming large-scale surveys are expected to uncover a large n…
