The Mid-Infrared Properties of Blue Compact Dwarf Galaxies
نویسندگان
چکیده
The unprecedented sensitivity of the Spitzer Space Telescope has enabled us for the first time to detect a large sample of Blue Compact Dwarf galaxies (BCDs), which are intrinsically faint in the infrared. In the present paper we present a summary of our findings which providing essential information on the presence/absence of the Polycyclic Aromatic Hydrocarbon features in metal-poor environments. In addition, using Spitzer/IRS high-resolution spectroscopy, we study the elemental abundances of neon and sulfur in BCDs and compare with the results from optical studies. Finally, we present an analysis of the midand far-infrared to radio correlation in low luminosity low metallicity galaxies. Subject headings: galaxies: ISM — infrared: galaxies — infrared: ISM — ISM: dust, extinction — ISM: structure

Blue Compact Dwarf Galaxies with Spitzer: the Infrared/radio Properties
We study the correlation between the radio, mid-infrared, and far-infrared properties for a sample of 28 blue compact dwarf (BCD) and low-metallicity star-forming galaxies observed by Spitzer. We find that these sources extend the same far-infraredYtoYradio correlation typical of star-forming late-type galaxies to lower luminosities. In BCDs, the 24 m (or 22 m) mid-infraredYtoYradio correlation...
متن کاملDust in the Extremely Metal-poor Blue Compact Dwarf Galaxy Izw18: the Spitzer Mid-infrared View
IZw18, a blue compact dwarf (BCD) galaxy with the 2nd lowest metallicity measured in a starforming object, has been observed with all three instruments on board the Spitzer Space Telescope. We present the deepest 5−36μmmid-infrared (mid-IR) spectrum of this galaxy as yet obtained, as well as 3.6μm to 70μm imaging results. As with SBS0335-052E, another BCD with similar metallicity, I Zw18 shows ...

New infrared and millimeter observations from Keck, Palomar, ISO, and OVRO and archival data from the NRAO VLA and IRAS are presented for the low metallicity blue compact dwarf galaxy SBS 0335-052. Mid-infrared imaging shows this young star-forming system is compact (0. 31; 80 pc) at 12.5 μm. The large Brγ equivalent width (235 Å) measured from integral field spectroscopy is indicative of a ∼5 ...
متن کاملThe Extraordinary Mid-infrared Spectrum of the Blue Compact Dwarf Galaxy Sbs 0335 052
SBS0335-052 is a blue compact dwarf galaxy (BCD) with one of the lowest known metallicities, Z∼Z⊙/41, making it a local example of how primordial starburst galaxies and their precursors might appear. A spectrum obtained with the Infrared Spectrograph (IRS) on the Spitzer Space Telescope clearly shows silicate absorption features, emission lines of [SIV] and [NeIII], and puts strong upper limits...
