Motti Intermediate Physics — HAL: Matter Fluctuations, Neutrino Mass Bounds, and Phase Transition Gravitational Waves

Key Points

• This research aims to explore cosmological predictions related to neutrino masses and gravitational waves.
• Analyzed three HAL cosmological predictions regarding sigma_8, neutrino mass bounds, and phase transition gravitational waves.
• Sigma_8 predicated at 0.7980, addressing sigma_8 tension (reduction of -1.6%).
• Neutrino mass bound established at sum(m_nu) < 0.11913 eV, a decrease of -0.87 meV.
• Phase transition gravitational waves enhanced by C0^2 = +1.46%.
