The Ly Alpha Reference Sample. I. Survey Outline and First Results for Markarian 259

Popis výsledku v původním jazyce

The Lyman-Alpha Reference Sample (LARS) is a substantial program with the Hubble Space Telescope (HST) that provides a sample of local universe laboratory galaxies in which to study the detailed astrophysics of the visibility and strength of the Ly?lineof neutral hydrogen. Ly-alpha is the dominant spectral line in use for characterizing high-redshift galaxies. This paper presents an overview of the survey, its selection function, and HST imaging observations. The final sample of 14 galaxies covers far-UV luminosities that overlap with those of high-z Ly-alpha emitters (LAEs) and Lyman break galaxies (LBGs), making LARS a valid comparison sample. We present the reduction steps used to obtain the Ly-alpha images, including our LARS eXtraction software,which utilizes pixel-by-pixel spectral synthesis fitting of the energy distribution to determine and subtract the continuum at Ly-alpha. To exemplify the science potential of LARS, we also present some first results for a single galaxy, M
