First Detection of 12CO (1--0) Emission from Two Narrow-Line Seyfert 1 Galaxies
T. Kawaguchi, K. Nakanishi, K. Kohno +2
In order to investigate how the growth of galactic bulges progresses with the growth of central black holes (BHs), we observed molecular gas (fuel for the coming star formation) in…
Millimeter Interferometric HCN(1-0) and HCO+(1-0) Observations of Luminous Infrared Galaxies
Masatoshi Imanishi, Kouichiro Nakanishi, Yoichi Tamura +2
We present the results on millimeter interferometric observations of four luminous infrared galaxies (LIRGs), Arp 220, Mrk 231, IRAS 08572+3915, and VV 114, and one Wolf-Rayet gala…
Observation Campaign of SS 433 in April 2006
T. Kotani, K. Kubota, M. Namiki +19
A radio-IR-optical-X-ray observation campaign of SS 433 has been performed in April 2006, when the jet axis is almost perpendicular to the line of sight. Five flares have been dete…
Millimeter Interferometric Investigations of the Energy Sources of Three Ultraluminous Infrared Galaxies, UGC 5101, Mrk 273, and IRAS 17208-0014, based on HCN to HCO+ Ratios
Masatoshi Imanishi, Kouichiro Nakanishi, Kotaro Kohno
We present interferometric observations of three ultraluminous infrared galaxies (ULIRGs; UGC 5101, Mrk 273, and IRAS 17208-0014) in the 3-mm wavelength range, using the Nobeyama M…
A high-frequency radio survey of low-luminosity active galactic nuclei
A. Doi, S. Kameno, K. Kohno +2
We investigate the high-frequency radio spectra of twenty low-luminosity active galactic nuclei (LLAGNs) with compact radio cores. Our millimetre survey with the Nobeyama Millimetr…
Nature of a Strongly-Lensed Submillimeter Galaxy SMM J14011+0252
K. Motohara, T. Takata, F. Iwamuro +6
We have carried out near-infrared JHK spectroscopy of a gravitationally lensed submillimeter galaxy SMM J14011+0252 at z=2.565, using OHS and CISCO on the Subaru telescope. This ob…
