Outside-in Shrinking of the Star-forming Disk of Dwarf Irregular Galaxies
Hong-Xin Zhang, Deidre A. Hunter, Bruce G. Elmegreen +2
We have studied multi-band surface brightness profiles of a representative sample of 34 nearby dwarf irregular galaxies (dIrrs). Our data include GALEX FUV/NUV, UBV, Hα, and Spitze…
Mapping the Extended HI Distribution of Three Dwarf Galaxies
Deidre A. Hunter, Fakhri Zahedy, Emily C. Bowsher +3
We present large field HI-line emission maps obtained with the single-dish Green Bank Telescope centered on the dwarf irregular galaxies Sextans A, NGC 2366, and WLM. We do not det…
Deep Radio Continuum Imaging of the Dwarf Irregular Galaxy IC10: Tracing Star Formation and Magnetic Fields
Volker Heesen, Urvashi Rau, Michael Rupen +2
We exploit the vastly increased sensitivity of the Expanded Very Large Array (EVLA) to study the radio continuum and polarization properties of the post-starburst, dwarf irregular…
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…
The long-lasting activity of 3C 454.3. GASP-WEBT and satellite observations in 2008-2010
C. M. Raiteri, M. Villata, M. F. Aller +6
We present multiwavelength observations of 3C 454.3 from April 2008 to March 2010. The radio to optical data are mostly from the GASP-WEBT, UV and X-ray data from Swift, and gamma-…
The Wolf-Rayet Content of M33
Kathryn F. Neugent, Philip Massey
Wolf-Rayet stars (WRs) are evolved massive stars, and the relative number of WC-type and WN-type WRs should vary with metallicity, providing a sensitive test of stellar evolutionar…
