ASTE CO(3--2) Survey of Elliptical Galaxies
Hiroyuki Nakanishi, Tomoka Tosaki, Kotaro Kohno +2
We report CO(3--2) observations of 15 nearby elliptical galaxies carried out with the ASTE telescope. Thirteen were selected without regard to the presence of other trac…
Environmental Effects on Gaseous Disks of the Virgo Spiral Galaxies
Hiroyuki Nakanishi, Nario Kuno, Yoshiaki Sofue +8
We found high molecular fractions (; ratio of the molecular to total gas surface densities) in three of five Virgo spiral galaxies in spite of their low total gas colu…
ASTE observations of nearby galaxies: A tight correlation between CO(J=3-2) emission and Halpha
Shinya Komugi, Kotaro Kohno, Tomoka Tosaki +4
Star formation rates (SFRs) obtained via extinction corrected H alpha are compared to dense gas as traced by CO(J=3-2) emission at the centers of nearby galaxies, observed with the…
