Dear colleague,
we are pleased to announce the conference
"Escape of Lyman radiation from galactic labyrinths".
This conference will be held on 11-14 September 2018, in Kolymbari,
a beautiful seaside village 20 km west of the city of Chania
on the island of Crete (Greece).
Please distribute this notice to your colleagues, and kindly post
this conference information on any relevant sites.
The outline of the Conference is given below and also at the
Conference website: http://www.iastro.pt/lyman2018

************************************************************
*Scientific Rationale*
The genesis and escape of Lyman alpha and continuum radiation on
galactic and sub-galactic scales is a result of a complex and subtle
interplay between the dynamical constituents of evolving galaxies.
Whereas the Lyman radiation produced by massive stars, AGN and shocks
has been studied in detail, our knowledge on how Lyman photons, once
they are produced, are reprocessed within a galaxy is woefully
incomplete, especially when it comes to the mechanisms facilitating
and regulating their escape into the galactic halo and beyond.
On sub-galactic scales, the pathways of Lyman photons from young
stellar clusters and HII regions into the ambient diffuse ionized gas,
and their imprints on the physical properties of the multi-phase ISM
are still obscure. 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 that route
and what mechanisms regulate the escape of Lyman photons out of the
galaxy labyrinth is an unsolved enigma. Similarly, how Lyman photon
escape, and its evolution with time are related to the growth of
galaxies and to various star-formation rate indicators remains a
longstanding puzzle.
The escape fraction of Lyman radiation along the co-evolution of AGN
with their galaxy hosts and in different environments - from evolving
HII regions all the way to galaxy mergers and massive early-type
galaxies - are further examples of subjects with key astrophysical
relevance where our knowledge is largely incomplete.
A final question concerns how escaping Lyman radiation illuminates the
cosmic web and may influence galaxy evolution over larger cosmic
volumes?
The meeting aims at bringing observers and theoreticians together
towards a joint exploration of the Odyssey that Lyman radiation
undergoes as it attempts to escape the galaxy labyrinth. This meeting
is motivated by astrophysically important questions, such as:
- how is the assembly history of galaxies and evolving physical properties
of their multi-phase ISM related to the escape fraction of Lyman 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 imprints does Lyman photon escape from galaxies leave
on the intergalactic medium and the cosmic web?
- what modeling concepts and observational constraints are most needed
for achieving a breakthrough in our understanding of Lyman photon escape
both at sub-galactic and galactic scales?
*Topics*
i. Production, transport and escape of Lyman radiation
ii. Lyman photon escape in star-forming galaxies
iii. Lyman photon escape in the presence of accretion-powered nuclear
activity in galaxies
iv. The evolution of the Lyman photon escape fraction across cosmic time
v. Challenges and opportunities: observational and theoretical input
towards a better understanding of Lyman photon production and escape
along the galaxy assembly history

Opening of registration & abstract submission: April 1, 2018
Deadline for abstract submission: May 28, 2018
Announcement of the program: June 11, 2018
Deadline for regular registration: August 20, 2018
*Proceedings*
The conference will have no proceedings, but the contributions
will be published on our webpage.
*Venue and Registration*
(see http://www.iastro.pt/lyman2018 for details)
The conference will take place at Orthodox Academy of Crete (OAC;
http://www.oac.gr), a public welfare institution.
The OAC is located in a beautiful environment next to the village of
Kolymbari, about 20 km from the city of Chania.
OAC offers 60 rooms (all with two beds or one twin-size bed), 5 of
which are suites (i.e. suitable for families).
If you wish accommodation at OAC (4 nights: Monday 10th September to
Thursday 13th September)
please choose option 1-4 (first come first served policy).
Conference participants who prefer to make their own accommodation
arrangements (options 5-6) can choose among several
conveniently located (15-30 min walking distance) hotels in Kolymbari.
For options 1-4 the conference fee (CF) includes full-board
accommodation (breakfast + 2 meals according to the traditional Cretan
cuisine at OAC), whereas options 5-6 include only lunch and dinner at
OAC.
Additionally, the conference fee includes the welcome reception,
access to wireless LAN, coffee breaks, the conference dinner (which
will be followed by a concert) and, for all participants except for
accompanying persons, the "conference material" (T-shirt, bag, etc.).
Option CF Remarks
