Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). XVI. 69 New Quasars at 5.8 < z < 7.0
Yoshiki Matsuoka, Kazushi Iwasawa, Masafusa Onoue +41
We present the spectroscopic discovery of 69 quasars at 5.8 < z < 7.0, drawn from the Hyper Suprime-Cam (HSC) Subaru Strategic Program (SSP) imaging survey data. This is the 16th p…
ALMA Sub-arcsec-resolution 183 GHz H2O and Dense Molecular Line Observations of Nearby Ultraluminous Infrared Galaxies
Masatoshi Imanishi, Kouichiro Nakanishi, Takuma Izumi +1
We present the results of ALMA 2 mm, 1-resolution observations of ten (ultra)luminous infrared galaxies ([U]LIRGs; infrared luminosity 10L$_{…
The MBHBM Project -- II. Molecular Gas Kinematics in the Lenticular Galaxy NGC 3593 Reveal a Supermassive Black Hole
Dieu D. Nguyen, Martin Bureau, Sabine Thater +15
As part of the Measuring Black Holes in Below Milky Way-mass (M) galaxies (MBHBM) Project, we present a dynamical measurement of the supermassive black hole (SMBH)…
Hard X-ray Irradiation Potentially Drives Negative AGN Feedback by Altering Molecular Gas Properties
Taiki Kawamuro, Claudio Ricci, Takuma Izumi +4
To investigate the role of active galactic nucleus (AGN) X-ray irradiation on the interstellar medium (ISM), we systematically analyzed Chandra and ALMA CO(=2-1) data for 26 ult…
An ACA Survey of [CI] , CO , and Dust Continuum in Nearby U/LIRG
Tomonari Michiyama, Toshiki Saito, Ken-ichi Tadaki +11
We present the results of surveying [CI] , CO , and 630 m dust continuum emission for 36 nearby ultra/luminous infrared galaxies (U/LIRGs) using the B…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). XIV. A Candidate Type-II Quasar at z=6.1292
Masafusa Onoue, Yoshiki Matsuoka, Nobunari Kashikawa +13
We present deep Keck/MOSFIRE near-infrared spectroscopy of a strong Lyman alpha emitting source at z=6.1292, HSC J142331.71-001809.1, which was discovered by the SHELLQS program fr…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). XIII. Large-scale Feedback and Star Formation in a Low-Luminosity Quasar at z = 7.07 on the Local Black Hole to Host Mass Relation
Takuma Izumi, Yoshiki Matsuoka, Seiji Fujimoto +22
We present ALMA [CII] 158 m line and underlying far-infrared (FIR) continuum emission observations ( resolution) toward HSC J124353.93010038.5 (J1243…
Circumnuclear Multi-phase Gas in Circinus Galaxy IV: absorption owing to high- CO rotational transitions
Taisei Uzuo, Keiichi Wada, Takuma Izumi +3
We studied the absorption features of CO lines against the continuum originating from the heated dust in the obscuring tori around active galactic nuclei (AGNs). We investigated th…
Black hole mass measurement using ALMA observations of [CI] and CO emissions in the Seyfert 1 galaxy NGC7469
Dieu D. Nguyen, Takuma Izumi, Sabine Thater +11
We present a supermassive black hole (SMBH) mass measurement in the Seyfert 1 galaxy NGC7469 using Atacama Large Millimeter/submillimeter Array (ALMA) observations of the atomic-${…
ALMA detection of millimetre 183 GHz H2O maser emission in the Superantennae galaxy at z ~ 0.06
