A New Framework for Multi-Line Analysis Combined Kernel PCA and Kernel SHAP: A Case of NGC 1068 ALMA Band 3 Data
Hiroma Okubo, Tsutomu T. Takeuchi, Shotaro Akaho +7
We present a new framework for multi-line analysis that combines kernel principal component analysis (Kernel PCA), an unsupervised machine-learning method, and Kernel SHapley Addit…
CO Multi-line Imaging of Nearby Galaxies (COMING). XI. Azimuthally averaged star formation rate and stellar mass relation with molecular gas amount
Ayumi Kajikawa, Kazuo Sorai, Kana Morokuma-Matsui +13
This study investigated the relation between the surface density of star formation rate (SFR) (), stellar mass (), and molecular gas mass ($Σ_{M_\ma…
The connection between galaxy mergers, star formation and AGN activity in the HSC-SSP
Kiyoaki Christopher Omori, Connor Bottrell, Sabine Bellstedt +6
Internal gas inflows driven by galaxy mergers are considered to enhance star formation rates (SFR), fuel supermassive black hole growth and stimulate active galactic nuclei (AGN).…
Solving Self-calibration of ALMA Data with an Optimization Method
Shiro Ikeda, Takeshi Nakazato, Takashi Tsukagoshi +2
We reformulate the gain correction problem of the radio interferometry as an optimization problem with regularization, which is solved efficiently with an iterative algorithm. Comb…
