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'.

This is the last seminar of the spring semester. First event in the 
autumn will be
