SDSS-IV MaNGA: Cannibalism Caught in the Act -- on the Frequency of Occurrence of Multiple Cores in Brightest Cluster Galaxies
Yun-Hsin Hsu, Yen-Ting Lin, Song Huang +16
Although it is generally accepted that massive galaxies form in a two-phased fashion, beginning with a rapid mass buildup through intense starburst activities, followed by primaril…
Dissecting Nearby Galaxies with piXedfit: I. Spatially Resolved Properties of Stars, Dust, and Gas as Revealed by Panchromatic SED Fitting
Abdurro'uf, Yen-Ting Lin, Hiroyuki Hirashita +5
We study spatially resolved properties (on spatial scales of kpc out to at least effective radii) of the stars, dust, and gas in ten nearby spiral galaxies. The prop…
Third Data Release of the Hyper Suprime-Cam Subaru Strategic Program
Hiroaki Aihara, Yusra AlSayyad, Makoto Ando +64
The paper presents the third data release of Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP), a wide-field multi-band imaging survey with the Subaru 8.2m telescope. HSC-SSP ha…
Brightest Cluster Galaxies Are Statistically Special From to
Roohi Dalal, Michael A. Strauss, Tomomi Sunayama +5
We study Brightest Cluster Galaxies (BCGs) in galaxy clusters from the Hyper Suprime-Cam (HSC) Subaru Strategic Program. The sample is selected over an area of 830 $\tex…
Identifying AGN host galaxies by Machine Learning with HSC+WISE
Yu-Yen Chang, Bau-Ching Hsieh, Wei-Hao Wang +5
We use machine learning techniques to investigate their performance in classifying active galactic nuclei (AGNs), including X-ray selected AGNs (XAGNs), infrared selected AGNs (IRA…
On the Constraints of Galaxy Assembly Bias in Velocity Space
Kevin S. McCarthy, Zheng Zheng, Hong Guo +2
If the formation of central galaxies in dark matter haloes traces the assembly history of their host haloes, in haloes of fixed mass, central galaxy clustering may show dependence…
Subaru Hyper Suprime-Cam excavates colossal over- and under-dense structures over 360 deg2 out to z=1
Rhythm Shimakawa, Yuichi Higuchi, Masato Shirasaki +8
Subaru Strategic Program with the Hyper-Suprime Cam (HSC-SSP) has proven to be successful with its extremely-wide area coverage in past years. Taking advantages of this feature, we…
Introducing piXedfit -- a Spectral Energy Distribution Fitting Code Designed for Resolved Sources
Abdurro'uf, Yen-Ting Lin, Po-Feng Wu +1
We present piXedfit, pixelized spectral energy distribution (SED) fitting, a Python package that provides tools for analyzing spatially resolved properties of galaxies using multib…
SITELLE Hα Imaging Spectroscopy of z~0.25 Clusters: Emission Line Galaxy Detection and Ionized Gas Offset in Abell 2390 & Abell 2465
Qing Liu, Howard Yee, Laurent Drissen +9
Environmental effects are crucial to the understanding of the evolution of galaxies in dense environments, such as galaxy clusters. Using the large field-of-view of SITELLE, the un…
