Environmental Regulation of Dust and Star Formation Unveiled by Subaru Dual Narrow-band Imaging: Degree-scale Balmer Decrement Mapping across a z = 0.9 Supercluster
Zhaoran Liu, Tadayuki Kodama, Brian C. Lemaux +13
We present results from a dual narrow-band imaging survey targeting the CL1604 supercluster at z = 0.9 using the Subaru Telescope. By combining the NB921 filter on HSC and the NB12…
Early-type Galaxies on the Star Formation Main Sequence: Internal Star Formation Geometry Revealed with MaNGA and Their Environmental Origin
Shuhei Koyama, Yusei Koyama, Takuji Yamashita +3
Star-forming galaxies on the main sequence (MS) are often regarded as a uniform population characterized by similar global star formation properties. However, there exists a divers…
A recoiling supermassive black hole in a powerful quasar
Marco Chiaberge, Takahiro Morishita, Matteo Boschini +14
Supermassive black holes (SMBH) are thought to grow through accretion of matter and mergers. Models of SMBH mergers have long suffered the final parsec problem, where SMBH binaries…
Development of a near-infrared wide-field integral field unit by ultra-precision diamond cutting
Kosuke Kushibiki, Shinobu Ozaki, Masahiro Takeda +17
Integral Field Spectroscopy (IFS) is an observational method to obtain spatially resolved spectra over a specific field of view (FoV) in a single exposure. In recent years, near-in…
Multiple emission lines of H emitters at from the broad and medium-band photometry in the ZFOURGE Survey
Nuo Chen, Kentaro Motohara, Lee R. Spitler +8
We present a multiple emission lines study of 1300 H emitters (HAEs) at in the ZFOURGE survey. In contrast to the traditional spectroscopic method, our sample…
EMPRESS. VIII. A New Determination of Primordial He Abundance with Extremely Metal-Poor Galaxies: A Suggestion of the Lepton Asymmetry and Implications for the Hubble Tension
Akinori Matsumoto, Masami Ouchi, Kimihiko Nakajima +42
The primordial He abundance is a powerful probe of cosmology. Currently, is best determined by observations of metal-poor galaxies, while there are on…
Environmental impact on star-forming galaxies in a cluster during course of galaxy accretion
Tetsuro Asano, Tadayuki Kodama, Kentaro Motohara +18
Galaxies change their properties as they assemble into clusters. In order to understand the physics behind that, we need to go back in time and observe directly what is occurring i…
