Heavy element abundances in blue compact galaxies
Y. I. Izotov, T. X. Thuan
We present high-quality ground-based spectroscopic observations of 54 supergiant H II regions in 50 low-metallicity blue compact galaxies with oxygen abundances 12 + log O/H betwee…
15um ISO observations of a CFRS field: the cosmic SFR as derived from UV, optical, mid-IR and radio photometry
H. Flores, F. Hammer, T. Thuan +7
The CFRS 1452+52 field has been deeply imaged with the Infrared Space Observatory (ISO) using ISOCAM through the LW3 filter (12-18um). Careful data analysis and comparison to deep…
Deep Galaxy survey at 6.75 micron with the ISO satellite
H. Flores, F. Hammer, F. X. Désert +8
Deep 6.75um mid-IR ISOCAM observations were obtained of the Canada-France Redshift Survey (CFRS) 1415+52 field with the Infrared Space Observatory. The identification of the source…
Dust in an extremely metal-poor galaxy: mid-infrared observations of SBS 0335-052
T. X. Thuan, M. Sauvage, S. Madden
The metal deficient (Z = Z_sun/41) Blue Compact Dwarf Galaxy (BCD) SBS 0335-052 was observed with ISOCAM between 5 and 17 mic. With a L_12mic/L_B ratio of 2.15, the galaxy is unexp…
Globular Clusters in Dwarf Elliptical Galaxies
B. W. Miller, H. C. Ferguson, J. Lotz +2
Globular clusters (GCs) provide one way of determining when the most important periods of star formation in dwarf elliptical (dE) galaxies occurred. Thus, they are also useful for…
Molecular Gas in Mrk 109: Constraining the O2/CO Ratio in Chemically Young Galaxies
D. T. Frayer, E. R. Seaquist, T. X. Thuan +1
We report on observations of CO(1-0) emission from the chemically young starburst galaxy Mrk 109. These observations were part of a study to constrain the O2/CO ratio in metal-defi…
