    • Bayesian inference in single-line spectroscopic binaries with a visual orbit 
      Videla Araya, Miguel; Méndez Bussard, René; Clavería, Rubén; Silva Sánchez, Jorge; Orchard Concha, Marcos (IOP, 2022)
      We present a Bayesian inference methodology for the estimation of orbital parameters on single-line spectroscopic binaries with astrometric data, based on the No-U-Turn sampler Markov chain Monte Carlo algorithm. Our ...

S.; Tollerud, E. J.; Adamow, M.; Hernandez Lang, D.; Kuropatkin, N.; Santana Silva, L.; Tucker, D. L.; Zenteno, A. (IOP, 2021)
      We present the discovery of a candidate ultra-faint Milky-Way satellite, Eridanus IV (DELVE J0505-0931), detected in photometric data from the DECam Local Volume Exploration survey (DELVE). Eridanus IV is a faint (M-V = - ...
