Description
The Laser Interferometer Space Antenna (LISA) offers a unique opportunity to probe the early universe through the detection of stochastic gravitational wave backgrounds. In this talk, I will review recent progress within the LISA Cosmology Working Group in analyzing these signals as probes of physics beyond the Standard Model. I will focus on early-universe sources such as first-order cosmological phase transitions and cosmic strings, highlighting their predicted signatures and the key challenges that must be addressed to fully exploit LISA’s scientific potential.
