SUMMARY:Multimessenger constraints on intergalactic magnetic fields\, 
 NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Rafael Alves Batista\, Uni
 versidad Autónoma de Madrid
DESCRIPTION:The most traditional and promising way to probe intergalac
 tic magnetic fields (IGMFs) is using gamma rays produced in electromag
 netic cascades initiated by high-energy gamma rays in the intergalacti
 c space. Because the charged component of the cascade is sensitive to 
 intervening magnetic fields\, it is possible to probe IGMFs by combini
 ng spectral\, temporal\, and angular information from distant sources 
 of high-energy gamma rays such as blazars. High-energy cosmic rays\, t
 oo\, being charged\, can provide insights into IGMFs\, although this i
 s more complicated given that their sources remain to be found. At the
  dawn of the multimessenger era\, a third probe can be used to help us
  solve this puzzle: neutrinos.
\nIn this talk I will firstly motivate 
 the quest for understanding cosmic magnetogenesis and review the statu
 s of studies of IGMFs with neutrinos\, cosmic rays\, and gamma rays. I
  will then describe a novel multimessenger strategy for probing IGMFs 
 using combined gamma-ray and neutrino observations from flaring object
 s. Finally\, I will present the first constraints on the coherence len
 gth of IGMFs obtained with this method.
