Near-Infrared Survey and Photometric Redshifts in the Extended GOODS-North field
Li-Ting Hsu, Lihwai Lin, Mark Dickinson +22
We present deep and -band images in the extended Great Observatories Origins Deep Survey-North (GOODS-N) field covering an area of 0.22 . The observations were…
Halo Concentrations and the Fundamental Plane of Galaxy Clusters
Yutaka Fujita, Megan Donahue, Stefano Ettori +6
According to the standard cold dark matter (CDM) cosmology, the structure of dark halos including those of galaxy clusters reflects their mass accretion history. Older clusters ten…
Time Evolution of 3D Disk Formation with Misaligned Magnetic Field and Rotation Axes
Miikka S. Väisälä, Hsien Shang, Ruben Krasnopolsky +3
Distinguishing diagnostic observational signatures produced by MHD models is essential in understanding the physics for the formation of protostellar disks in the ALMA era. Develop…
Does the mid-infrared-hard X-ray luminosity relation for active galactic nuclei depend on Eddington ratio?
Yoshiki Toba, Yoshihiro Ueda, Kenta Matsuoka +5
We revisit the correlation between the mid-infrared (6 m) and hard X-ray (2--10 keV) luminosities of active galactic nuclei (AGNs) to understand the physics behind it. We constr…
Dusty Superwind from a Galaxy with a Compact Obscured Nucleus: Optical Spectroscopic Study of NGC 4418
Youichi Ohyama, Kazushi Sakamoto, Susanne Aalto +1
We report our optical spectroscopic study of the nucleus and its surrounding region of a nearby luminous infrared galaxy NGC 4418. This galaxy has been known to host a compact obsc…
Faraday rotation in the jet of M87 inside the Bondi radius: indication of winds from hot accretion flows confining the relativistic jet
Jongho Park, Kazuhiro Hada, Motoki Kino +3
We study Faraday rotation in the jet of M87 inside the Bondi radius using eight Very Long Baseline Array data sets, one at 8 GHz, four at 5 GHz, and three at 2 GHz. We obtain Farad…
Line-of-sight gas sloshing in the cool core of Abell 907
Shutaro Ueda, Yuto Ichinohe, Tetsu Kitayama +1
We present line-of-sight gas sloshing first found in a cool core in a galaxy cluster. The galaxy cluster Abell 907 is identified as a relaxed cluster owing to its global X-ray surf…
Anomalously low metallicity regions in MaNGA star-forming galaxies: Accretion Caught in Action?
Hsiang-Chih Hwang, Jorge K. Barrera-Ballesteros, Timothy M. Heckman +14
We use data from 1222 late-type star-forming galaxies in the SDSS IV MaNGA survey to identify regions in which the gas-phase metallicity is anomalously-low compared to expectations…
OSSOS XII: Variability studies of 65 Trans-Neptunian Objects using the Hyper Suprime-Cam
Mike Alexandersen, Susan D. Benecchi, Ying-Tung Chen +11
We present variability measurements and partial light curves of Trans-Neptunian Objects (TNOs) from a two-night pilot study using Hyper Suprime-Cam (HSC) on the Subaru Telescope (M…
A Balloon-Borne Very Long Baseline Interferometry Experiment in the Stratosphere: Systems Design and Developments
Akihiro Doi, Yusuke Kono, Kimihiro Kimura +33
The balloon-borne very long baseline interferometry (VLBI) experiment is a technical feasibility study for performing radio interferometry in the stratosphere. The flight model has…
The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library
D. S. Aguado, Romina Ahumada, Andres Almeida +230
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years o…
Molecular-Cloud-Scale Chemical Composition III: Constraints of Average Physical Properties through Chemical Models
Nanase Harada, Yuri Nishimura, Yoshimasa Watanabe +4
It is important to understand the origin of molecular line intensities and chemical composition in the molecular-cloud scale in the Galactic sources because it serves as a benchmar…
ALMA High Angular Resolution Polarization Study; An Extremely Young Class 0 Source, OMC-3/MMS 6
Satoko Takahashi, Masahiro N. Machida, Kohji Tomisaka +4
Using the 15km ALMA long baselines, we imaged the Stokes emission and linearly polarized intensity () in the 1.1-mm continuum band of a very young intermediate-mas…
Col-OSSOS: Color and Inclination are Correlated Throughout the Kuiper Belt
Michael Marsset, Wesley C. Fraser, Rosemary E. Pike +12
Both physical and dynamical properties must be considered to constrain the origins of the dynamically excited distant Solar System populations. We present high-precision (g-r) colo…
The wavelength dependence of interstellar polarization in the Local Hot Bubble
Daniel V. Cotton, Jonathan P. Marshall, Priscilla C. Frisch +6
The properties of dust in the interstellar medium (ISM) nearest the Sun are poorly understood because the low column densities of dust toward nearby stars induce little photometric…
Gas Flows Within Cavities of Circumbinary Discs in Eccentric Binary Protostellar Systems
Philipp Mösta, Ronald E. Taam, Paul C. Duffell
The structure and evolution of gas flows within the cavity of a circumbinary disk (CBD) surrounding the stellar components in eccentric binaries are examined via two-dimensional hy…
