Spectrally and spatially resolved (sub)millimeter HCN-to-HCO flux ratios in nearby ultraluminous infrared galaxies
Masatoshi Imanishi, Yuri Nishimura, Shunsuke Baba +2
We present the results of our investigations of spectrally and spatially resolved (sub)millimeter HCN-to-HCO flux ratios at J=2-1, J=3-2, and/or J=4-3 in 18 nearby ( 0.1…

A High Incidence of Mid-infrared Variability in Local Ultraluminous Infrared Galaxies
Shun Hatano, Masatoshi Imanishi, Takanobu Kirihara +3
We explore mid-infrared (MIR) variability in local ultraluminous infrared galaxies (ULIRGs; infrared luminsoity ) utilizing the 11 years of photo…
