Galaxy Spectra Networks (GaSNet). III. Generative pre-trained network for spectrum reconstruction, redshift estimate and anomaly detection
Fucheng Zhong, Nicola R. Napolitano, Caroline Heneka +11
Classification of spectra (1) and anomaly detection (2) are fundamental steps to guarantee the highest accuracy in redshift measurements (3) in modern all-sky spectroscopic surveys…
Efficient Experimental Qudit State Estimation via Point Tomography
D. Martínez, L. Pereira, K. Sawada +7
Point tomography is a new approach to the problem of state estimation, which is arguably the most efficient and simple method for modern high-precision quantum information experime…
Uncertainty estimation for time series classification: Exploring predictive uncertainty in transformer-based models for variable stars
Martina Cádiz-Leyton, Guillermo Cabrera-Vives, Pavlos Protopapas +3
Classifying variable stars is key for understanding stellar evolution and galactic dynamics. With the demands of large astronomical surveys, machine learning models, especially att…
Quasispecies dynamics with time lags and periodic fluctuations in replication
Edward A. Turner, Francisco Crespo, Josep Sardanyés +1
Quasispecies theory provides the conceptual and theoretical bases for describing the dynamics of biological information of replicators subject to large mutation rates. This theory,…
Feedback from intermediate mass black holes on dwarf galaxy morphology at z=2
Da Bi, Dominik R. G. Schleicher, Andres Escala
This study investigates the influence of intermediate-mass black holes (IMBHs) on galactic morphology, focusing on their evolution within dwarf galaxies at high redshift (z~2). Usi…
Asymptotic structure of three-dimensional Maxwell Chern-Simons gravity coupled to spin-3 fields
Patrick Concha, Javier Matulich, Daniel Pino +1
In this work we analyze the asymptotic symmetries of the three-dimensional Chern-Simons (CS) gravity theory for a higher spin extension of the so-called Maxwell algebra. We propose…
