The Multimodal Universe: Enabling Large-Scale Machine Learning with 100TB of Astronomical Scientific Data

Posted by dbos Cambridge

Kavli Affiliate: Kaisey Mandel | First 5 Authors: The Multimodal Universe Collaboration, Jeroen Audenaert, Micah Bowles, Benjamin M. Boyd, David Chemaly | Summary: We present the MULTIMODAL UNIVERSE, a large-scale multimodal dataset of scientific astronomical data, compiled specifically to facilitate machine learning research. Overall, the MULTIMODAL UNIVERSE contains hundreds of millions of astronomical observations, constituting […]

Clustering and Runaway Merging in a Primordial Black Hole Dominated Universe

Posted by dbos Chicago

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 […]

Uncovering the Effects of Array Mutual Coupling in 21-cm Experiments with the SKA-Low Radio Telescope

Posted by dbos Cambridge

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 […]

Formation Rate of Quasi-periodic Eruptions in Galactic Nuclei Containing Single and Dual Supermassive Black Holes

Posted by dbos Peking

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 […]

Neutrino Diffusion within Dark Matter Spikes

Posted by dbos Tokyo

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 […]
