    • Characterizing The V-Band Light-Curves Of Hydrogen-Rich Type II Supernovae. 
      Anderson, Joseph P.; González Gaitán, Santiago; Hamuy Wackenhut, Mario; Gutiérrez, Claudia P.; Stritzinger, Maximilian D.; Olivares, Felipe; Phillips, Mark M.; Schulze, Steve; Antezana, Roberto; Bolt, Luis; Campillay, Abdo; Castellón, Sergio; Contreras, Carlos; De Jaeger, Thomas; Folatelli, Gastón; Förster, Francisco; Freedman, Wendy L.; González, Luis; Hsiao, Eric; Krzeminski, Wojtek; Krisciunas, Kevin; Maza Sancho, José; McCarthy, Patrick; Morrell, Nidia; Persson, Sven E.; Roth, Miguel; Salgado, Francisco; Suntzeff, Nicholas B.; Thomas Osip, Joanna (The American Astronomical Society, 2014-05)
      We present an analysis of the diversity of V-band light-curves of hydrogen-rich type II supernovae. Analyzing a sample of 116 supernovae, several magnitude measurements are defined, together with decline rates at ...
    • Deep-HiTS: Rotation Invariant Convolutional Neural Network for Transient Detection 
      Cabrera Vives, Guillermo; Reyes, Ignacio; Förster, Francisco; Estévez Valencia, Pablo; Maureira, Juan Carlos (Institute of Physics, 2017)
      We introduce Deep-HiTS, a rotation invariant convolutional neuralnetwork (CNN) model for clas-sifying images of transients candidates into artifacts or real sources for the High cadence TransientSurvey (HiTS). CNNs have ...
    • Morphological analysis of the centimeter-wave continuum in the dark cloud LDN 1622 
      Casassus Montero, Simón; Cabrera, G. F.; Förster, Francisco; Pearson, Timothy J.; Readhead, A. C. S.; Dickinson, Clive (UNIV CHICAGO PRESS, 2006-03-10)
      The spectral energy distribution of the dark cloud LDN 1622, as measured by Finkbeiner using WMAP data, drops above 30 GHz and is suggestive of a Boltzmann cutoff in grain rotation frequencies, characteristic of spinning ...
    • Robust period estimation using mutual information for multiband light curves in the synoptic survey era 
      Huijse, Pablo; Estévez, Pablo; Förster, Francisco; Daniel, Scott; Connolly, Andrew; Protopapas, Pavlos; Carrasco, Rodrigo; Príncipe, José (Institute of Physics Publishing, 2018)
      The Large Synoptic Survey Telescope (LSST) will produce an unprecedented amount of light curves using six optical bands. Robust and efficient methods that can aggregate data from multidimensional sparsely-sampled time ...
    • Serendipitous discovery of RR lyrae stars in the leo v ultra-faint galaxy 
      Medina, Gustavo E.; Muñoz Vidal, Ricardo Rodrigo; Vivas, A. Katherina; Förster, Francisco; Carlin, Jeffrey L.; Martínez, Jorge; Galbany, Lluis; González Gaitán, Santiago; Hamuy Wackenhut, Mario; Jaeger, Thomas De; Maureira, Juan Carlos; San Martín, Jaime (Institute of Physics, 2017)
      During the analysis of RR Lyrae stars (RRLs) discovered in the High Cadence Transient Survey (HiTS) taken with the Dark Energy Camera at the 4 m telescope at Cerro Tololo Inter-American Observatory, we found a group of ...
