DESCRIPTION:Speakers: Joan Doria\, Andrea Guerrero\n\nSearch for anomalous
  events in CTAO-LST1 observations\nAndrea Guerrero - (Gamma Ray group)\nLS
 T-1 is the first operational Large-Sized Telescope of the Cherenkov Telesc
 ope Array Observatory (CTAO)\, designed to perform ground-based gamma-ray 
 astronomy by capturing the brief flashes of Cherenkov light generated when
  very-high-energy photons interact with the Earth's atmosphere. It has bee
 n working since 2019\, however\, could the observations be affected by the
  recording of undesired events? No previous study on the search for anomal
 ies had been carried out with LST-1. We developed an anomaly detection pip
 eline\, as well as a satellite identification tool to identify and charact
 erize such events. By characterizing every observed anomaly\, we leave roo
 m for the discovery of unidentified phenomena.\nMapping the young Universe
 \nJoan Doria - (Observational Cosmology group)\nThe evolution of the Unive
 rse is still not fully understood\, particularly during its early stages w
 hen the first large-scale structures were forming. Studying the distributi
 on of matter at high redshift provides valuable information about the grow
 th of cosmic structure and the underlying cosmological model. To study it\
 , we have analyzed two complementary probes of this distant matter distrib
 ution: CMB gravitational lensing and the Lyman-Alpha forest from distant q
 uasars. For this purpose\, we have used CoLoRe simulations which provide a
  CMB lensing map as well as Lyman Alpha forest fluctuations. This allows u
 s to validate the analysis in a controlled environment.  These results pr
 ovide a basis for future joint analyses of these two probes.\n\nhttps://in
