A gradient boosting and broadband approach to finding Lyman-α emitting galaxies beyond narrowband surveys
A. Vale, A. Paulino-Afonso, A. Humphrey +5
In this work, we test whether gradient-boosting algorithms, trained on broadband photometric data from traditional Lyman- emitting (LAE) surveys, can efficiently and accurately…

Temperature and high-pressure dependent X-ray absorption of SmNiO3 at the Ni K- and Sm L3- edges
Néstor E. Massa, Aline Y. Ramos, Helio C. N. Tolentino +3
We report on XANES and EXAFS measurements of SmNiO3 from 20 K to 600 K and up to 38 GPa at the Ni K- and Sm L3- edges. A multiple component pre- Ni K-edge tail is understood origin…
