The Outer Disks of Dwarf Irregular Galaxies
Deidre A. Hunter, Bruce G. Elmegreen, Se-Heon Oh +5
To explore the properties of extreme outer stellar disks, we obtained ultra-deep V and GALEX UV images of 4 dwarf irregular galaxies and one Blue Compact Dwarf galaxy and ultra-dee…
VII Zw 403: HI Structure in a Blue Compact Dwarf Galaxy
Caroline E. Simpson, Deidre A. Hunter, Tyler E. Nordgren +9
We present optical (UBVJ), ultraviolet (FUV, NUV), and high resolution atomic hydrogen (HI) observations of the nearby blue compact dwarf (BCD), VII Zw 403. We find that VII Zw 403…
A High-Resolution Study of the HI Content of Local Group Dwarf Irregular Galaxy WLM
Amanda Kepley, Eric Wilcots, Deidre Hunter +1
Dwarf irregular galaxies are unique laboratories for studying the interaction between stars and the interstellar medium in low mass environments. We present the highest spatial res…
Initial Results from the USNO Dispersed Fourier Transform Spectrograph
Arsen R. Hajian, Bradford B. Behr, Andrew T. Cenko +15
We have designed and constructed a ``dispersed Fourier Transform Spectrometer'' (dFTS), consisting of a conventional FTS followed by a grating spectrometer. By combining these two…
DDO 43: A Prototypical Dwarf Irregular Galaxy?
Caroline E. Simpson, Deidre A. Hunter, Tyler E. Nordgren
We present sensitive and high resolution 21 cm observations of the dwarf irregular (dIm) galaxy DDO 43, in conjunction with optical broad and narrow band images in U, B, V, and Hal…
Predicted and empirical radii of RR Lyrae stars
M. Marconi, T. Nordgren, G. Bono +2
We present new theoretical Period-Radius-Metallicity (PRZ) relations for RR Lyrae stars. Current predictions are based on a large set of nonlinear, convective models that cover a b…
