DESCRIPTION:Speakers: Göran Östlin (Stockholm University\, OKC)\, Matthe
 w Hayes (IRAP)\, Garrelt Mellema (Stockholm University\, OKC)\n\nVenue\n\n
 \n\nNordita\, Stockholm\, Sweden\n\nScope\n\n This program is about the Ly
  α transition in Hydrogen and its astrophysical applications. Young stell
 ar populations are dominated by massive\, hot and short-lived stars that i
 onize their surroundings. Hydrogen recombination lines reprocess the ioniz
 ing radiation and are therefore ubiquitously strong in star forming region
 s. The intrinsically strongest line is Ly α (following the transition fro
 m the first excited state to the ground state) and with a rest wavelength 
 in the far Ultra Violet it has become the most used spectral probe of the 
 distant universe\, and is used to assemble large samples of high redshift 
 galaxies. However\, the line is a resonant one and the absorption cross se
 ction in neutral Hydrogen is high\, meaning that Ly α photons have a tend
 ency to scatter in the interstellar medium in galaxies. Ly α is hence a p
 owerful\, but complicated\, probe of star forming and high redshift galaxi
 es. This programs aims to bring together experts in modeling Ly α radiati
 ve transfer and galaxy formation\, and observations of Ly α in local gala
 xies and the distant universe.\n\nDuring the second week of the program\, 
 9-13 September 2013\, there will be a workshop.\n\n[Timetable]\n\n[Slides 
 from talks]\n\nFurther information\n\nYou can find more information about 
 this program and the workshop 9-13 September on the home page of the Astro
 nomy Department at Stockholm University.\n\nApplication\n\nIf you want to 
 apply for participation in the program\, please fill in the application fo
 rm.\n\nYou should use this application form both if you intend to particip
 ate in the program 2-6 and 16-27 September as well as if you will only be 
 attending the workshop 9-13 September.\n\nYou will be informed by the orga
 nizers shortly after the application deadline whether your application has
  been approved. Due to space restrictions\, the total number of participan
 ts is strictly limited. (Invited speakers are of course automatically appr
 oved\, but need to register anyway.)\n\nApplication deadline: 14 July 2013
 \n\nA minimum stay of one working week is required and we encourage partic
 ipants to stay for a period of at least two weeks.\n\n\n\nSponsored by:\n\
