Insights into Jet-Induced Cloud Disruption in NGC 1316: ALMA Reveals a Spatially Extended Molecular Gas

Kana Morokuma-Matsui, Alexander Y. Wagner, Filippo M. Maccagni +14

We present ALMA CO() observations of a nearby radio galaxy NGC1316 at a 100-pc resolution to investigate the impact of AGN jets on the molecular gas. The molecular gas exhib…

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…

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…
