DESCRIPTION:Speakers: Adriano Fontana\, Benedetta Ciardi\, Pascal Oesch\, 
 Richard Ellis\, Alice Shapley\n\n\n\nUnderstanding the physical processes 
 that led to the formation of the first stars and galaxies is one of themos
 t exciting issues in modern astronomy and physics as a whole. This is a co
 mplex problem that involves arange of scales from the small\, where black 
 holes (BH) and stars form\, to the large\, where the circumgalacticand int
 ergalactic media (IGM) are ionised and chemically enriched. To make progre
 ss we must address anumber of astrophysical challenges\, e.g. star- and BH
 -formation\, heavy element production and radiativetransfer through multi-
 phase environments. Importantly\, advancing this field may reveal evidence
  of newphysical processes such as primordial BHs of non-stellar origin and
  even fundamentally new ingredients ofthe universe.The required observatio
 nal data must come from the first billion years after the Big Bang – an 
 epoch that hasescaped detailed observations until recently. This is becaus
 e of the necessity for sensitive instrumentationoperating at wavelengths l
 onger than 2 μm beyond the capabilities of the Hubble Space Telescope (HS
 T)and ground-based observatories. Recently\, however\, the observational s
 ituation has been completelyrevolutionised by the advent of the James Webb
  Space Telescope (JWST). With a larger aperture and anextended wavelength 
 coverage\, JWST offers unrivalled opportunities for studies of early galax
 ies. A majoradvantage is its extensive suite of instruments\, which provid
 e broad- and intermediate-band imagingcapabilities as well as multi-slit a
 nd slitless spectroscopy with a range of resolutions.\n\nThe launch of the
  James Webb Space Telescope (JWST) in 2021 has revolutionized our understa
 nding of the early universe\, with over 300 scientific articles published 
 on early galaxies and black holes since operations began in July 2022. The
  telescope has dramatically increased our detection and characterization o
 f high-redshift galaxies and AGN\, and has led to several puzzles that inc
 lude a large number of luminous and massive galaxies\, and a high abundanc
 e of AGN. This is an incredibly exciting and dynamic period in observation
 al astronomy. Yet there is still no clear picture emerging of the most bas
 ic questions that motivated JWST in the mid-1990s. When did the first gala
 xies emerge from darkness? What seeds led to the SMBHS that fuel quasars a
 s early as at times corresponding to redshifts z~7? How did reionisation p
 rogress and what were the contributing sources? Fortunately\, JWST will no
 t be alone in exploring this era. Both the Atacama Millimetre Array (ALMA)
  and soon the Square Kilometre Array (SKA) can provide complementary data 
 on\, respectively\, the dust content of early galaxies and the topology of
  the neutral IGM. Shortly thereafter\, ESO’s Extremely Large Telescope (
 ELT) will offer higher angular resolution and improved signal to noise mea
 surements compared to JWST\, enabling new insight into the resolved dynami
 cs\, stellar content and physical processes in selected sources.\nThis fou
 r-week MIAPbP workshop will bring together observers and theorists to achi
 eve a consolidated physical summary of the exciting new results from the f
 irst four years of JWST science operations. We will review the census of e
 arly star-forming galaxies\, early BH demographics and growth mechanisms\,
  the ionizing properties of early sources and their role in reionization\,
  and the prospect of detecting pristine stellar populations. We will thus 
 discuss future plans for JWST\, guided by theoretical developments. What s
 hould JWST achieve during the next five years and what should our observin
 g strategies be with complementary and future facilities like ALMA\, SKA\,
  and ELT?\n\n\n\n\nhttps://indico.ph.tum.de/event/8010/
