Insights into the dependence of galaxy properties on the environment with explainable machine learning models
Shun-ya S. Uchida, Suchetha Cooray, Atsushi J. Nishizawa +2
Galaxies reside within dark matter halos, but their properties are influenced not only by their halo properties but also by the surrounding environment. We construct an interpretab…
A Potential Link between Nuclear Winds and Cold Gas Outflows on Kiloparsec Scales in Reionization-Era Quasars
Yongda Zhu, Marcia J. Rieke, Luis C. Ho +23
Feedback from accreting supermassive black holes may regulate galaxy evolution, but statistical evidence linking nuclear winds to kiloparsec-scale cold gas outflows remains limited…
A new constraint on galaxy-halo connections of [O II] emitters via HOD modelling with angular clustering and luminosity functions from the Subaru HSC survey
Shogo Ishikawa, Teppei Okumura, Masao Hayashi +1
Establishing a robust connection model between emission-line galaxies (ELGs) and their host dark haloes is of paramount importance in anticipation of upcoming redshift surveys. We…

We report the discovery of a unique quasar-dusty star-forming galaxy (DSFG) system at , consisting of the bright quasar J1133+1603 () and its compact…
sOPTICS: A Modified Density-Based Algorithm for Identifying Galaxy Groups/Clusters and Brightest Cluster Galaxies
Hai-Xia Ma, Tsutomu T. Takeuchi, Suchetha Cooray +1
A direct approach to studying the galaxy-halo connection is to analyze groups and clusters of galaxies that trace the underlying dark matter halos, emphasizing the importance of id…
Extracting an Informative Latent Representation of High-Dimensional Galaxy Spectra
Daiki Iwasaki, Suchetha Cooray, Tsutomu T. Takeuchi
To understand the fundamental parameters of galaxy evolution, we investigated the minimum set of parameters that explain the observed galaxy spectra in the local Universe. We ident…
High Dimensional Statistical Analysis and its Application to ALMA Map of NGC 253
Tsutomu T. Takeuchi, Kazuyoshi Yata, Kento Egashira +6
In astronomy, if we denote the dimension of data as and the number of samples as , we often meet a case with . Traditionally, such a situation is regarded as ill-po…
An Empirical Estimation of the Galaxy Radio Number Counts model at 3~GHz and the Effect of Gravitational Lensing
K. T. Kono, T. T. Takeuchi
We analyzed the evolution of 3GHz luminosity function of radio selected galaxies through cosmic time, up to about 1 Gyr after Big Bang, with making use of the VLA-COSMOS3GHz large…
