Kavli Affiliate: George Ricker | First 5 Authors: Marcelo Tala Pinto, Andrés Jordán, Lorena Acuña, Matías Jones, Rafael Brahm | Summary: We report the discovery and characterization of three new transiting giant planets orbiting TOI-6628, TOI-3837 and TOI-5027, and one new warm sub-Saturn orbiting TOI-2328, whose transits events were detected in the lightcurves of the […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Ian Holst, Gordan Krnjaic, Huangyu Xiao, , | Summary: If primordial black holes (PBH) are present in the early universe, their contribution to the energy budget grows relative to that of radiation and generically becomes dominant unless the initial abundance is exponentially small. This black hole domination […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Oscar S. D. O’Hara, Quentin Gueuning, Eloy de Lera Acedo, Fred Dulwich, John Cumner | Summary: We investigate the impact of Mutual Coupling (MC) between antennas on the time-delay power spectrum response of the core of the SKA-Low radio telescope. Using two in-house tools – Fast Array […]

Kavli Affiliate: Xian Chen | First 5 Authors: Chunyang Cao, F. K. Liu, Xian Chen, Shuo Li, | Summary: Quasi-periodic eruptions (QPEs) are a novel class of transients recently discovered in a few extragalactic nuclei. It has been suggested that a QPE can be produced by a main-sequence star undergoing repeated partial disruptions by the […]

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Motoko Fujiwara, Gonzalo Herrera, Shunsaku Horiuchi, , | Summary: Multi-messenger observations of astrophysical transients provide powerful probes of the underlying physics of the source as well as beyond the Standard Model effects. We explore transients that can occur in the vicinity of supermassive black holes at the […]
Kavli Affiliate: Blake Sherwin | First 5 Authors: Andrew Laverick, Kristen Surrao, Inigo Zubeldia, Boris Bolliet, Miles Cranmer | Summary: Multi-agent systems (MAS) utilizing multiple Large Language Model agents with Retrieval Augmented Generation and that can execute code locally may become beneficial in cosmological data analysis. Here, we illustrate a first small step towards AI-assisted […]
