    • Delaunay based algorithm for finding polygonal voids in planar point sets 
      Alonso, R.; Ojeda, J.; Hitschfeld Kahler, Nancy; Hervías-Caimapo, Carlos; Campusano Brown, Luis (Elsevier, 2018)
      This paper presents a new algorithm to find under-dense regions called voids inside a 2D point set. The algorithm starts from terminal-edges (local longest-edges) in a Delaunay triangulation and builds the largest possible ...
    • Radiation damage effects in space-borne CCD detectors operated in TDI mode 
      Terrazas Vargas, Juan; Corcione, L.; Lattanzi, M.G.; Gai, M. (IOP Publishing, 2017-07-01)
      We evaluate the astrometric and photometric implications of a series of laboratory tests conducted to study the effects of radiation damage caused by solar protons in space-borne charge coupled devices (CCDs). The photometric ...
    • Short time-scale variability in the Faint Sky Variability Survey 
      Morales Rueda, L.; Groot, P. J.; Augusteijn, T.; Nelemans, G.; Vreeswijk, Paul M.; Besselaar, E. J. M. van den (Blackwell, 2006)
      We present the V-band variability analysis of the point sources in the Faint Sky Variability Survey on time-scales from 24 min to tens of days. We find that about one per cent of the point sources down to V = 24 are ...
    • Statistically-based methodology for revealing real contagion trends and correcting delay-induced errors in ... 
      Contreras, Sebastián; Biron Lattes, Juan Pablo; Villavicencio, Andrés; Medina Ortiz, David; Llanovarced Kawles, Nyna Koyllor; Olivera Nappa, Álvaro (Elsevier, 2020)
      COVID-19 pandemic has reshaped our world in a timescale much shorter than what we can understand. Particularities of SARS-CoV-2, such as its persistence in surfaces and the lack of a curative treatment or vaccine against ...
