A new determination of the primordial He abundance using the HeI 10830A emission line: cosmological implications
Y. I. Izotov, T. X. Thuan, N. G. Guseva
We present near-infrared spectroscopic observations of the high-intensity HeI 10830 emission line in 45 low-metallicity HII regions. We combined these NIR data with spectroscopic d…

The X-ray Properties of the Cometary Blue Compact Dwarf galaxies Mrk 59 and Mrk 71
T. X. Thuan, F. E. Bauer, Y. I. Izotov
We present XMM-Newton and Chandra observations of two low-metallicity cometary blue compact dwarf (BCD) galaxies, Mrk 59 and Mrk 71. The first BCD, Mrk 59, contains two ultralumino…
