Searching Stochastic Gravitational Wave Background Landscape Across Frequency Bands
Yunjia Bao, Tore Boybeyi, Vuk Mandic +1
Gravitational wave (GW) astrophysics is entering a multi-band era with upcoming GW detectors, enabling detailed mapping of the stochastic GW background across vast frequencies. We…
Uncool soft-wall transitions and gravitational waves
Ameen Ismail, Lian-Tao Wang
Theories with warped extra dimensions, like the Randall-Sundrum (RS) model, exhibit a holographic phase transition from a hot, deconfined black brane phase to a cool, confined phas…
Anatomy of Parity-violating Trispectra in Galaxy Surveys
Yunjia Bao, Lian-Tao Wang, Zhong-Zhi Xianyu +1
Parity-violating interactions are ubiquitous phenomena in particle physics. If they are significant during cosmic inflation, they can leave imprints on primordial perturbations and…
Anisotropic Gravitational Waves from Anisotropic Axion Rotation
Arushi Bodas, Keisuke Harigaya, Keisuke Inomata +2
Gravitational waves (GWs) provide a powerful probe of the early universe due to their ability to free-stream across cosmic history. We study GW production in a compelling scenario…
Acoustic Misalignment Mechanism for Axion Dark Matter
Arushi Bodas, Raymond T. Co, Akshay Ghalsasi +2
A rotation in the field space of a complex scalar field corresponds to a Bose-Einstein condensation of charges. We point out that fluctuations in this rotating condensate ex…
Crescendo Beyond the Horizon: More Gravitational Waves from Domain Walls Bounded by Inflated Cosmic Strings
Yunjia Bao, Keisuke Harigaya, Lian-Tao Wang
Gravitational-wave (GW) signals offer a unique window into the dynamics of the early universe. GWs may be generated by the topological defects produced in the early universe, which…
