An Aromatic Inventory of the Local Volume
A. R. Marble, C. W. Engelbracht, L. van Zee +13
Using infrared photometry from the Spitzer Space Telescope, we perform the first inventory of aromatic feature emission (AFE, but also commonly referred to as PAH emission) for a s…
Chemical Abundances of Seven Irregular and Three Tidal Dwarf Galaxies in the M81 Group
Kevin V. Croxall, Liese van Zee, Henry Lee +5
We have derived nebular abundances for 10 dwarf galaxies belonging to the M81 Group, including several galaxies which do not have abundances previously reported in the literature.…
Interstellar Medium Oxygen Abundances of Dwarf Irregular Galaxies in Centaurus A and Nearby Groups
Henry Lee, D. B. Zucker, E. K. Grebel
We present results of optical spectroscopy of 35 H II regions from eight dwarf galaxies in the Centaurus A group. [O III]4363 A is detected in ESO272-G025 and ESO324-G024, and dire…
The Extinction and Distance of Maffei 2 and a New View of the IC 342/Maffei Group
Robin L. Fingerhut, Henry Lee, Marshall L. McCall +1
We have obtained spectra of HII regions in the heavily obscured spiral galaxy Maffei 2. The observations have allowed for a determination of the Galactic extinction of this galaxy…
On Extending the Mass-Metallicity Relation of Galaxies by 2.5 Decades in Stellar Mass
Henry Lee, Evan D. Skillman, John M. Cannon +4
We report 4.5 micron luminosities for 27 nearby (D < 5 Mpc) dwarf irregular galaxies measured with the Spitzer Infrared Array Camera. We have constructed the 4.5 micron luminosity-…
Hot Dust and PAH Emission at Low Metallicity: A Spitzer Survey of Local Group and Other Nearby Dwarf Galaxies
Dale C. Jackson, John M. Cannon, Evan D. Skillman +4
We present Spitzer Space Telescope 4.5 and 8.0 micron imaging of 15 Local Group and nearby dwarf galaxies. Our sample spans a range of more than one dex in nebular metallicity and…
