H emission in the outskirts of galaxies at z=0.4
Rhythm Shimakawa, Masayuki Tanaka, Satoshi Kikuta +1
This paper reports detections of H emission and stellar continuum out to approximately 30 physical kpc, and H directionality in the outskirts of H-emitting galaxies (H…
Environmental dependence of gas properties in a protocluster at z~2.5
Kohei Aoyama, Tadayuki Kodama, Tomoko L. Suzuki +5
In a protocluster USS1558-003 at z=2.53, galaxies in the dense cores show systematically elevated star-forming activities than those in less dense regions. To understand its origin…
Where's Swimmy?: Mining unique color features buried in galaxies by deep anomaly detection using Subaru Hyper Suprime-Cam data
Takumi S. Tanaka, Rhythm Shimakawa, Kazuhiro Shimasaku +4
We present the Swimmy (Subaru WIde-field Machine-learning anoMalY) survey program, a deep-learning-based search for unique sources using multicolored () imaging data from th…
Subaru Hyper Suprime-Cam revisits the large-scale environmental dependence on galaxy morphology over 360 deg at z=0.3-0.6
Rhythm Shimakawa, Takumi S. Tanaka, Seiji Toshikage +1
This study investigates the role of large-scale environments on the fraction of spiral galaxies at 0.3-0.6 sliced to three redshift bins of . Here, we sample 276220 ma…
What determines the HI gas content in galaxies?: morphological dependence of the HI gas fraction across M*-SFR plane
Shigeru V. Namiki, Yusei Koyama, Shuhei Koyama +5
We perform a stacking analysis of the HI spectra from the Arecibo Legacy Fast ALFA (ALFALFA) survey for optically-selected local galaxies from the Sloan Digital Sky Survey (SDSS) t…
COALAS: I. ATCA CO(1-0) survey and luminosity function in the Spiderweb protocluster at z=2.16
S. Jin, H. Dannerbauer, B. Emonts +25
We report a detailed CO(1-0) survey of a galaxy protocluster field at , based on 475 hours of observations with the Australia Telescope Compact Array. We constructed a larg…
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…
