An Evaluation of Hybrid Annotation Workflows on High-Ambiguity Spatiotemporal Video Footage
Juan Gutiérrez, Victor Gutiérrez, Ángel Mora +2
Manual annotation remains the gold standard for high-quality, dense temporal video datasets, yet it is inherently time-consuming. Vision-language models can aid human annotators an…
Strong-lensing rates of massive black hole binaries in LISA
Juan Gutiérrez, Macarena Lagos
Similarly to electromagnetic (EM) signals, gravitational lensing by intervening galaxies can also affect gravitational waves (GWs). In this paper, we estimate the strong-lensing ra…
Open-Source System for Multilingual Translation and Cloned Speech Synthesis
Mateo Cámara, Juan Gutiérrez, María Pilar Daza +1
We present an open-source system designed for multilingual translation and speech regeneration, addressing challenges in communication and accessibility across diverse linguistic c…
The Dark Ages Explorer (DEX): a filled-aperture ultra-long wavelength radio interferometer on the lunar far side
C. D. Brinkerink, M. J. Arts, M. J. Bentum +21
The measurement of the spatial fluctuations of the neutral hydrogen 21 cm signal arising during the Dark Ages and Cosmic Dawn periods of our Universe (z from 200 to 10) holds the p…
