The Structure and Stellar Content of the Outer Disks of Galaxies: A New View from the Pan-STARRS1 Medium Deep Survey
Z. Zheng, D. Thilker, T. Heckman +11
We present the results of an analysis of Pan-STARRS1 Medium Deep Survey multi-band (g,r,i,z,y) images of a sample of 698 low-redshift disk galaxies that span broad ranges in stella…
The initial mass function and star formation law in the outer disc of NGC 2915
S. M. Bruzzese, G. R. Meurer, C. D. P. Lagos +4
Using Hubble Space Telescope (HST) ACS/WFC data we present the photometry and spatial distribution of resolved stellar populations in the outskirts of NGC 2915, a blue compact dwar…
Choirs HI Galaxy Groups: The metallicity of dwarf galaxies
Sarah M. Sweet, Michael J. Drinkwater, Gerhardt Meurer +4
We present a recalibration of the luminosity-metallicity relation for gas-rich, star-forming dwarfs to magnitudes as faint as M ~ -13. We use the Dopita et al. (2013) metallici…
