Rationale
The genesis and escape of Lyman
alpha and continuum radiation on galactic and subgalactic
scales is a result of a complex and subtle interplay between
the dynamical constituents of evolving galaxies. Our knowledge
on how Lyman radiation produced by massive stars, AGN and
shocks is further processed within a galaxy is woefully
incomplete.
On subgalactic scales, the pathways of Lyman photons from
young stellar clusters and HII regions into the surrounding
diffuse ionized gas, and their imprints on the physical
properties of the multi-phase ISM are still unclear. On
galactic scales, the scattering Odyssey of Lyman-alpha photons
from their birthplace out to the galactic halo remains to be
written. How feedback processes shape the 3D structure,
chemical abundance patterns and kinematics of the gas along
this route, and what mechanisms regulate the escape of Lyman
radiation out of the galaxy Labyrinth is an unsolved enigma.
The escape fraction of Lyman radiation along the co-evolution
of AGN with their galaxy hosts is another subject with key
astrophysical relevance where our knowledge is still largely
incomplete. A final question concerns how escaping Lyman
radiation can illuminate the cosmic web and influence the
evolution of galaxies across larger cosmic volumes.
The goal of this meeting is to bring observers and
theoreticians together toward a joint exploration of the
Odyssey of Lyman radiation on its way out of the galaxy
Labyrinth.
This conference is motivated by questions such as:
- how are the formation history of
galaxies and the evolving physical properties of their
multi-phase ISM related to the escape fraction of
Lyman-alpha and Lyman-continuum photons?
- how does the escape of Lyman
radiation evolve with the rise and fall of star-forming
and accretion-powered nuclear activity in galaxies, and
what are its imprints on the circumgalactic medium and the
cosmic web?
- what modeling concepts and
observational constraints are most needed to achieve a
breakthrough in our understanding of Lyman photon escape
both at subgalactic and galactic scales?
