Binary neutron stars in the next-generation era: Multi-messenger detection prospects and constraints on the equation of state, mass distribution, and cosmology
Hauke Koehn, Thibeau Wouters, Gilad Sadeh +5
The paper forecasts how many binary neutron‑star mergers will be observed jointly in gravitational waves and electromagnetic light by next‑generation detectors like the Einstein Te…
The Dark Dimension meets the Axiverse
Kevin Langhoff, Maria Ramos, Mario Reig
The paper studies how combining dark dimension models with an axiverse affects early‑universe cosmology, showing that freeze‑in production of Kaluza‑Klein axion and graviton towers…
Outcomes of Grand Unified Symmetry Breaking
Harish Hemming, Tanmay Vachaspati, Anja Wachowitz
The paper numerically investigates symmetry breaking in Grand Unified models, showing that biased domain walls and magnetic monopoles form and interact, leading to phenomena such a…
micrOMEGAs 7: Beyond standard cosmology
G. Belanger, A. Belyaev, N. Bernal +4
micrOMEGAs 7 is an upgraded software package that computes dark‑matter observables while allowing user‑defined modifications to the early‑Universe expansion, entropy, and non‑therm…
Gravitational Wave Astronomy With TianQin
En-Kun Li, Shuai Liu, Alejandro Torres-Orjuela +50
The paper outlines the scientific potential of the TianQin space‑based gravitational‑wave observatory, describing the types of compact‑object sources it can detect in the mHz band…
Lectures on Open Systems and Cosmology
Enrico Pajer
These lecture notes introduce the operator formalism and Schwinger‑Keldysh path‑integral techniques for describing open systems, with a focus on their application to cosmology and…
