Discovery of Dying Active Galactic Nucleus in Arp 187: Experience of Drastic Luminosity Decline within years
Kohei Ichikawa, Junko Ueda, Hyun-Jin Bae +4
Arp 187 is one of the fading active galactic nuclei (AGN), whose AGN activity is currently decreasing in luminosity. We investigate the observational signatures of AGN in Arp 187,…
ALMA observations of HCN and HCO+ outflows in the merging galaxy NGC 3256
Tomonari Michiyama, Daisuke Iono, Kazimierz Sliwa +7
We report ~2" resolution Atacama Large Millimeter/submillimeter Array observations of the HCN(1-0), HCO+(1-0), CO(1-0), CO(2-1), and CO(3-2) lines towards the nearby merging double…
A gravitationally unstable gas disk of a starburst galaxy 12 billion years ago
Ken-ichi Tadaki, Daisuke Iono, Min S. Yun +18
Submillimeter bright galaxies in the early Universe are vigorously forming stars at ~1000 times higher rate than the Milky Way. A large fraction of stars is formed in the central 1…
SMA Observations of Extended Emission in Interacting Galaxy NGC 3627
Charles J. Law, Qizhou Zhang, Luca Ricci +5
We present moderate () and high angular resolution () observations of emission toward nearby, interacting ga…
Spatially-resolved Dense Molecular Gas Excitation in the Nearby LIRG VV 114
Toshiki Saito, Daisuke Iono, Daniel Espada +14
We present high-resolution observations (0".2-1".5) of multiple dense gas tracers, HCN and HCO ( = 1-0, 3-2, and 4-3), HNC ( = 1-0), and CS ( = 7-6) lines, toward the…
Discovery of an extremely-luminous dust-obscured galaxy observed with SDSS, WISE, JCMT, and SMA
Yoshiki Toba, Junko Ueda, Chen-Fatt Lim +5
We present the discovery of an extremely-luminous dust-obscured galaxy (DOG) at = 3.703, WISE J101326.25+611220.1. This DOG is selected as a candidate of extremely-l…
