. Yuri Gagarin - the first cosmonaut of our planet . Everybody knew him as a military pilot. He was worthy of his immense glory. He always was friendly, liked jokes, and had an enchanting smile, that showed breadth and wealth of his soul and at the same time the ability to brace up and concentrate. The hero who first opened the way to the cosmos for mankind should be just like this. prev. | index | . next .

Polycyclic aromatic hydrocarbons in HII regions: correlation with metallicity . ... We have perfomed the aperture photometry of HII regions using infrared images from telescopes Spitzer and Herschel at passbands 3.6, 4.5, 5.8, 8.0, 24, 70 and 160 m. Emission of PAHs are observed at passbands 3.6 - 8.0 m, 24 m is emission likely of hot small particles and finally large particles are responsible for emission at 70 and 160 m. We determine abundances of PAHs using model of Draine Li (2007) . ...
