SUMMARY:A Multi-Wavelength, Three-Dimensional View into Protocluster Enviro
 nments 
DESCRIPTION:A Multi-Wavelength, Three-Dimensional View into Protocluster En
 vironments \nDr. Sofia Gallego\n\nGalaxies are embedded within a network o
 f interconnected filaments,  essential for their formation and growth. Sim
 ultaneously, they emit  radiation and enriched matter back into their envi
 ronment, influencing  the evolution of the cosmic gas. Recent advancements
  in wide-field  spectrographs offer a unique perspective, allowing us to p
 robe the  spatial distribution and properties of the circumgalactic medium
  at high  redshift, particularly the Lyman-alpha line emitted by cold hydr
 ogen  gas. These insights are especially valuable in overdense regions, li
 ke  protoclusters and groups, where we can explore most of the physical  m
 echanisms at play. By combining data from instruments such as KCWI,  MOSFI
 RE, IRAC, LRIS, and HST, we aim to decipher the various mechanisms  that s
 teer the evolution of galaxies and protocluster environments  around the C
 osmic Noon epoch, unveiling how mergers, AGN feedback, and  galactic outfl
 ows influence both the large-scale gas distribution and  the general prope
 rties of the galaxies themselves. Nonetheless, several  degeneracies persi
 st among the observed properties of the gas and the  potential physical me
 chanisms responsible, underscoring the necessity  for improved models of t
 hese cosmic phenomena and a larger statistical  sample of protocluster env
 ironments.
