Understanding the epoch of cosmic Reionization
LOCATION: Sport & Kurhotel at Bad Moos - Via Val Fiscalina 27, 39030, Sexten
The birth of the first stars, galaxies and black holes heralded the end of the cosmic Dark
Ages, ushering in the Cosmic Dawn. Light from these objects spread out, heating and
ionizing virtually every baryon in our Universe. This Epoch of Reionization (EoR) was
the last major phase change of our Universe, encoding a wealth of information about
the unseen first galaxies and structures in the intergalactic medium (IGM). Despite
spanning the majority of our visible Universe, the EoR has only recently begun to be
explored. We now have many observational clues of the EoR, including from: (i) the
opacity of the Lyman alpha and beta forests; (ii) damping wing imprints in QSO
spectra; (iii) evolution of Lyman alpha emitting galaxies; (iv) clustering of Lyman alpha
emitters; (v) CMB polarization power spectra; (vi) the kinetic Sunyaev-Zel’Dovich
effect in CMB temperature fluctuations; (vii) the cosmic 21-cm signal. However,
interpreting these observations is challenging, requiring careful modeling of both the
cosmic signal as well as associated systematics.
This workshop will focus on putting together these pieces of the puzzle of reionization.
What was the timing of the EoR? What sources were responsible? How did they
interact with themselves and their surroundings through feedback mechanisms? What
are the associated observational signatures? What was the role of IGM structures?
How can we improve models of the EoR? How do we best build forward models,
accounting for relevant theoretical and observational systematics? Where are the next
observational breakthroughs? How do we best prepare for upcoming data from nextgeneration telescopes like JWST and SKA?
We expect around 30-40 participants, invite only. These will span experts in
observations, theory, as well as data science; breakthroughs in understanding require
synergy between all three of these aspects.
