COMPARISON OF Hα AND UV STAR FORMATION RATES IN THE LOCAL VOLUME: SYSTEMATIC DISCREPANCIES FOR DWARF GALAXIES
- Janice C. Lee, A. Paz, D. Weisz
- Physics
- 29 September 2009
Using a complete sample of ~300 star-forming galaxies within 11 Mpc of the Milky Way, we evaluate the consistency between star formation rates (SFRs) inferred from the far ultraviolet (FUV)…
The ACS Nearby Galaxy Survey Treasury
- J. Dalcanton, B. Williams, T. Quinn
- Physics
- 1 December 2007
The ACS Nearby Galaxy Survey Treasury (ANGST) is a systematic survey to establish a legacy of uniform multi-color photometry of resolved stars for a volume-limited sample of nearby galaxies (D 14…
On Extending the Mass-Metallicity Relation of Galaxies by 2.5 Decades in Stellar Mass
- Henry Lee, E. Skillman, M. Germany
- Physics
- 1 May 2006
We report 4.5 � m luminosities for 27 nearby (DP5 Mpc) dwarf irregular galaxies measured with the Spitzer Infrared Array Camera. We have constructed the 4.5 � m luminosity-metallicity (L-Z) relation…
Oxygen Abundances in Nearby Dwarf Irregular Galaxies
- E. Skillman, R. Kennicutt, P. Hodge
- Physics
- 1 December 1989
Oxygen abundances are obtained by optical spectrophotometry of H II regions in seven nearby dwarf irregular galaxies. All of these yield oxygen abundances of less than 1/10 of the solar value, and…
The Calibration of Monochromatic Far-Infrared Star Formation Rate Indicators
- D. Calzetti, S.-Y. Wu, Y. Wu
- Physics
- 4 March 2010
Spitzer data at 24, 70, and 160 μm and ground-based Hα images are analyzed for a sample of 189 nearby star-forming and starburst galaxies to investigate whether reliable star formation rate (SFR)…
Interstellar Abundance Gradients in NGC 2403: Comparison to M33
- D. Garnett, G. Shields, E. Skillman, S. Sagan, R. Dufour
- Physics
- 1 November 1997
We present new long-slit spectra of 12 H II regions in the Scd spiral galaxy NGC 2403. Gas-phase element abundances for O, N, S, Ne, and Ar were estimated using direct measurements of electron…
THE SPITZER LOCAL VOLUME LEGACY: SURVEY DESCRIPTION AND INFRARED PHOTOMETRY
The survey description and the near-, mid-, and far-infrared flux properties are presented for the 258 galaxies in the Local Volume Legacy (LVL). LVL is a Spitzer Space Telescope legacy program that…
Direct Oxygen Abundances for Low Luminosity LVL Galaxies
- D. Berg, E. Skillman, Benjamin D. Johnson
- Physics
- 30 May 2012
We present MMT spectroscopic observations of H II regions in 42 low luminosity galaxies in the Spitzer Local Volume Legacy survey. For 31 of the 42 galaxies in our sample, we were able to measure the…
The ACS Nearby Galaxy Survey Treasury. IX. Constraining Asymptotic Giant Branch Evolution with Old Metal-poor Galaxies
- L. Girardi, B. Williams, E. Skillman
- Physics
- 23 September 2010
In an attempt to constrain evolutionary models of the asymptotic giant branch (AGB) phase at the limit of low masses and low metallicities, we have examined the luminosity functions and number ratios…
Elemental Abundance Variations and Chemical Enrichment from Massive Stars in Starbursts. I. NGC 4214
- H. Kobulnicky, E. Skillman
- Physics
- 1 November 1996
This spectroscopic study of NGC 4214 is part of a project to determine the extent to which the winds and supernovae from massive stars contribute to the short-term, localized chemical enrichment of…
