I will present a brief overview of the current status of cosmology, and highlight what we can expect from the Euclid Dark Energy Mission which launched mid-2023.
The Subaru Prime Focus Spectrograph (PFS) cosmology program will deliver redshifts for four million [OII] emission-line galaxies over 1200 deg² across 𝑧 = 0.6 to 𝑧 = 2.4, based on approximately 100 nights of observations. The program has two primary goals: (1) to rule out the inverted neutrino mass hierarchy by measuring Σ𝑚𝜈 < 0.1 eV at 95% CL, or to determine the total neutrino mass if Σ𝑚𝜈 >...
The stochastic gravitational wave background (SGWB) provides a unique window into the early universe, offering insights into high-energy physics beyond the reach of conventional cosmological observations. Unlike the cosmic microwave background, which probes the universe after recombination, gravitational waves can propagate freely from the earliest moments after the Big Bang, carrying imprints...
