Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). XI. Proximity Zone Analysis for Faint Quasar Spectra at z~6
Rikako Ishimoto, Nobunari Kashikawa, Masafusa Onoue +14
We present measurements of the size of the quasar proximity zone () for eleven low-luminosity () quasars at , discovered by the Subaru H…
ALMA 0.02"-resolution observations reveal HCN-abundance-enhanced counter-rotating and outflowing dense molecular gas at the NGC 1068 nucleus
Masatoshi Imanishi, Dieu D. Nguyen, Keiichi Wada +6
We present ALMA ~0.02"-resolution observations of the nucleus of the nearby (~14 Mpc) type-2 AGN NGC 1068 at HCN/HCO+/HNC J=3-2 lines, as well as at their 13C isotopologue and vibr…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). IX. Identification of Two Red Quasars at z > 5.6
Nanako Kato, Yoshiki Matsuoka, Masafusa Onoue +14
We present the first discovery of dust-reddened quasars (red quasars) in the high-z universe (z >5.6). This is a result from the Subaru High-z Exploration of Low-Luminosity Quasars…
Circumnuclear Molecular Gas in Low-redshift Quasars and Matched Star-forming Galaxies
Takuma Izumi, John D. Silverman, Knud Jahnke +6
A series of gravitational instabilities in a circumnuclear gas disk (CND) are required to trigger gas transport to a central supermassive black hole (SMBH) and ignite Active Galact…
ALMA Observations of Multiple-CO and C Lines Toward the Active Galactic Nucleus of NGC 7469: X-Ray-dominated Region Caught in the Act
Takuma Izumi, Dieu D. Nguyen, Masatoshi Imanishi +15
We used the Atacama Large Millimeter/submillimeter Array (ALMA) to map CO( = 1-0), CO( = 2-1), CO( = 3-2), CO( = 2-1), and [CI](-$^3P…
AGN X-ray irradiation of CO gas in NGC 2110 revealed by and ALMA
Taiki Kawamuro, Takuma Izumi, Kyoko Onishi +3
We report spatial distributions of the Fe-K line at 6.4 keV and the CO( = 2--1) line at 230.538 GHz in NGC 2110, which are respectively revealed by and ALMA at $\ap…
Discovery of Radio Jets in Phoenix Galaxy Cluster Center
Takuya Akahori, Tetsu Kitayama, Shutaro Ueda +6
We report the results of the Australia Telescope Compact Array (ATCA) 15 mm observation of the Phoenix galaxy cluster possessing an extreme star-burst brightest cluster galaxy (BCG…
