We analyze the data from narrow band H-alpha and forbidden O III CCD imaging of a sample of nearby spiral galaxies with active nuclei. The results show that the...
Star formation efficiency patterns in the spiral arms of M51
The distribution of ionized, molecular, and atomic hydrogen in the disk and especially along the spiral arms of the Whirlpool galaxy, M51, is investigated by...
An analysis of the IRAS data for a sample of classical (optically selected) Seyfert galaxies is presented. The IRAS fluxes at 25 micron, 60 micron, and 100...
Star formation in the spiral arms of NGC 4321. I - CO observations
Several positions in the southern spiral arm and the interarm disk of NGC 4321 have been observed in CO (J = 1 to 0) using the NRO 45 m telescope at Nobeyama...
Star formation rates, efficiencies and initial mass functions in spiral galaxies
Using broad band photometry, a new method is derived to evaluate relative (arm with respect to the interarm disk) star formation rates and relative star...
Statistics and properties of H II regions in NGC 6814
We present a new H-alpha image of high quality of the grand-design galaxy NGC 6814, and describe statistical properties of the H II region population. We have...
Stellar and Gas Kinematics in the Core and Bar Regions of M100
Two-dimensional maps of the stellar and gas kinematics of the bar and starbursting circumnuclear region in the barred spiral galaxy M100 are presented. In this...
Using HI Nearby Galaxy Survey (THINGS) 21-cm observations of a sample of nearby (nearly face-on) galaxies we explore whether the stellar disk truncation...
