DESCRIPTION:Speakers: Mick Wright\n\nAbstract: Gravitational waves may exp
 erience a number of astrophysical phenomena on their path from emission to
  observation by the current ground-based gravitational wave detector netwo
 rk operated by the LIGO--Virgo--KAGRA (LVK) Scientific Collaborations. One
  of these phenomena is deflection due to the signal passing through the sp
 ace-time distortions of massive objects and being deflected in a process q
 ualitatively similar to the lensing of light through a lens. Gravitational
  lensing has been an important probe of dark matter through electromagneti
 c observations\, and observation in gravitational wave signals may be simi
 larly used\, or used to constrain cosmological parameters\, perform tests 
 of General Relativity\, and for other important scientific applications. T
 his seminar will present the means by which gravitational wave signals are
  examined by the LVK for signatures of lensing from a broad variety of pos
 sible lensing scenarios and present the results from these searches applie
 d to the latest catalog of gravitational wave events (GWTC-4.0). We will i
 n particular discuss the event GW231123 which had the highest support for 
 lensing of any event observed thus far and the difficulties in reaching a 
 definitive conclusion for this event.\n\nhttps://agenda.irmp.ucl.ac.be/eve
