Assessing the Impact of Unequal Noises and Foreground Modeling on SGWB Reconstruction with LISA / Kume, Jun'ya (U. Padua, Dept. Phys. Astron. ; INFN, Padua ; U. Tokyo (main)) ; 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. [...]

Gravitational waves from inflation in LISA: reconstruction pipeline and physics interpretation / LISA Cosmology Working Group Collaboration
Various scenarios of cosmic inflation enhance the amplitude of the stochastic gravitational wave background (SGWB) at frequencies detectable by the LISA detector. We develop tools for a template-based analysis of the SGWB and introduce a template databank to describe well-motivated signals from inflation, prototype their template-based searches, and forecast their reconstruction with LISA. [...]

Impact of a primordial gravitational wave background on LISA resolvable sources / Braglia, Matteo (New York U., CCPP) ; Pieroni, Mauro (CERN) ; Marsat, Sylvain (L2IT, Toulouse)
The existence of a primordial stochastic gravitational wave background (SGWB) is a common prediction in various models of the early Universe. Despite constraints at different frequency ranges and claims of detection in the nHz range by Pulsar Timing Arrays, the amplitude and spectral dependence of the SGWB in the mHz range remain largely unknown.

Forecasting the sensitivity of Pulsar Timing Arrays to gravitational wave backgrounds / Babak, Stanislav (APC, Paris) ; Falxa, Mikel (LPC2E, Orleans ; APC, Paris) ; Franciolini, Gabriele (CERN) ; Pieroni, Mauro (CERN)
Pulsar Timing Array (PTA) observations hinted towards the existence of a stochastic gravitational wave background (SGWB) in the nHz frequency band. Still, the nature of the SGWB signal cannot be confidently inferred from current data, and the leading explanation invokes mergers of supermassive black holes. [...]

Probing primordial black holes at high redshift with future gravitational wave detector / Marcoccia, Paolo (Stavanger U.) ; Nardini, Germano (Stavanger U.) ; Pieroni, Mauro (CERN)
We analyze the detection prospects for potential Primordial Black Hole Binary (PBHB) populations buried in the Stellar-Origin Black Hole Binary (SOBHB) population inferred by the LVK collaboration. We consider different PBHB population scenarios and several future Gravitational Wave (GW) detectors. [...]
