    1. 181. Electromagnetic Duality in Black Hole Mergers
      José Ferreira (University of Aveiro)

      Contributed Talk (20 minutes)

      The electromagnetic duality is a symmetry of Maxwell’s equations in vacuum that can be used as a method to generate dyonic or magnetic solutions from the purely charged case. Since this symmetry does not make any assumptions regarding the underlying geometry, it also applies to dynamical spacetimes. Here, we show that the emitted electromagnetic radiation differs between solutions in the same...

    2. 182. EEEC from CFT correlation functions
      Ricardo Almeida Rodrigues (University of Porto)
      02/10/2026, 14:35
      Contributed Talk (20 minutes)

      We extend event shape distributions for N detectors in conformal field theories. We explain how to compute this observable starting from the Euclidean kinematic by means of a non-trivial analytic continuation which can be elegantly performed in Mellin space. We study the formalism in detail for three scalar detectors in N=4 SYM both at weak and strong coupling and we also consider a mixed of...

    3. 201. EMRI dynamics around rotating boson stars
      Manuel Mariano (Universidade de Aveiro)

      Contributed Talk (20 minutes)

      Extreme mass-ratio inspirals (EMRIs) are expected to provide precision probes of strong field gravity and the nature of compact objects, making them key targets for LISA. While Kerr black holes remain the standard paradigm, exotic compact objects such as
      rotating boson stars have emerged as possible alternatives. These horizonless objects can have a toroidal energy distribution, leading to a...

    5. 194. A Freeze-In Interpretation of the LZ 248 keV Nuclear Recoil Event
      Vinícius Oliveira (Universidade de Aveiro)
      02/10/2026, 15:35
      Contributed Talk (20 minutes)

      The LUX-ZEPLIN (LZ) experiment recently reported a nuclear recoil candidate at $E_R \simeq 248 $ keV. Inelastic dark matter (DM) is among the best-motivated explanations of this signal, since it suppresses the low-energy recoils that elastic scattering would predict. However, in thermal freeze-out the relic density fixes the DM–nucleon cross section for a given mass. In this talk, based on...
