Title: Deciphering Lyman alpha emitting galaxies with integral field 
spectroscopy

Abstract:
Lyman alpha emitting high-redshift galaxies offer insights into galaxy 
formation processes in the young universe.  Moreover, they can be used 
to address cosmological questions regarding the "Epoch of Reionisation" 
and the nature of dark energy.  In my talk I will show how integral 
field spectroscopy (IFS) is a viable observational technique for such 
studies.  In particular, I will detail how we use IFS data to understand 
Lyman alpha escape mechanisms in a sample of nearby high-redshift 
analogues.  I will then show how we use the revolutionary IFS instrument 
MUSE for conducting surveys of Lyman emitting galaxies in the redshift 
range 3 < z < 6.  Here I will provide an overview over the latest 
results from those campaigns, with a particular focus on luminosity 
function studies. My talk will conclude with new (preliminary) results 
from a 17.5 hour MUSE integration of an extremely luminous extended 
z=3.1 Lyman alpha emitter known as 'Lyman Alpha Blob 1'.
