This site is currently under construction (hydrogen and helium atom setup routines are still missing), but eventually it should contain:

1. •Explanation of recombination physics
   

2. •My C++ version of Recfast, which includes several extensions
   

3. •Description of the new cosmological recombination code CosmoRec
   

4. •Routines to allow a detailed description of hydrogenic atoms
   

5. •Download section for different codes
   

If you are interested in updates, please email me: Jens@Chluba.de. I also already have several routines available that I will be very happy to share as they are now.
