Assessing the Impact of Unequal Noises and Foreground Modeling on SGWB Reconstruction with LISA / Kume, Jun'ya ; Peloso, Marco (Padua U. ; INFN, Padua) ; Pieroni, Mauro (CERN) ; Ricciardone, Angelo (Pisa U. ; INFN, Pisa)
In the search for stochastic gravitational wave backgrounds (SGWB) of cosmological origin with LISA, it is crucial to account for realistic complications in the noise and astrophysical foreground modeling that may impact the signal reconstruction. [...]

Tensionless String Limits in 4d Conformal Manifolds / Calderón-Infante, José (CERN) ; Valenzuela, Irene (CERN ; Madrid, Autonoma U. ; Madrid, IFT)
Drawing on insights from the Swampland program, we initiate a classification of infinite distance limits in the conformal manifolds of 4d SCFTs. [...]
