    • Cartier Ugarte, Regis (Universidad de Chile, 2014)
      La variabilidad de los núcleos activos de las galaxias (AGNs) es un fenómeno bien establecido, el cual puede ser observado en un amplio rango del espectro electromagnético; desde longitudes de onda en radio hasta los ...
    • Rabinowitz, David; Tourtellotte, Suzanne; Rojo, Patricio; Hoyer, Sergio; Folatelli, Gastón; Coppi, Paolo; Baltay, Charles; Bailyn, Charles (IOP PUBLISHING LTD, 2011-05-01)
      We report the discovery of an eclipsing cataclysmic variable with eclipse depths > 5.7 mag, orbital period 94.657 minutes, and peak brightness V similar to 18 at J2000 position 17(h)25(m)54(s). 8, -64 degrees 38'39 ''. ...
    • Dai, Lixin; Escala Astorquiza, Andrés; Coppi, Paolo (The American Astronomical Society, 2013-09-20)
      We have carried out general relativistic particle simulations of stars tidally disrupted by massive black holes. When a star is disrupted in a bound orbit with moderate eccentricity instead of a parabolic orbit, the ...
    • Cartier Ugarte, Regis; Hamuy Wackenhut, Mario; Pignata Libralato, Giuliano; Förster, Francisco; Zelaya, Paula; Folatelli, Gastón; Phillips, Mark M.; Morrell, Nidia; Krisciunas, Kevin; Suntzeff, Nicholas B.; Clocchiatti, Alejandro; Coppi, Paolo; Contreras, Carlos; Roth, Miguel; Koviak, Kathleen; Maza Sancho, José; González, Luis; González, Sergio; Huerta, Leonor (The American Astronomical Society, 2014-07-01)
      We present well-sampled UBVRIJHK photometry of SN 2002fk starting 12 days before maximum light through 122 days after peak brightness, along with a series of 15 optical spectra from −4 to +95 days since maximum. ...
    • Cartier Ugarte, Regis; Lira Teillery, Paulina; Coppi, Paolo; Sánchez, Paula; Arévalo, Patricia; Bauer, Franz; Rabinowitz, David; Zinn, Robert; Muñoz Vidal, Ricardo Rodrigo; Meza, Nicolás (IOP Pub., 2015)
      We present the characterization and initial results from the QUEST–La Silla active galactic nucleus (AGN) variability survey. This is an effort to obtain well-sampled optical light curves in extragalactic fields with ...
    • Gawiser, Eric; van Dokkum, Pieter; Herrera, David; Maza Sancho, José; Castander, Francisco; Infante, Leopoldo; Lira Teillery, Paulina; Quadri, Ryan; Toner, Ruth; Treister, Ezequiel; Urry, C. Megan; Altmann, Martín; Assef, Roberto; Christlein, Daniel; Coppi, Paolo; Durán, María Fernanda; Marijn, Franx; Galaz, Gaspar, 1967-; Huerta, Leonor; Charles, Liu; López Morales, Sebastián; Méndez Bussard, René Alejandro; Moore, David C.; Rubio López, Mónica; Ruiz González, María Teresa; Sune, Toft; Sukyoung K., Yi (IOP Publishing., 2006-01)
      We present UBVRIz0 optical images taken with MOSAIC on the CTIO 4 m telescope of the 0.32 deg2 Extended Hubble Deep Field–South. This is one of four fields comprising the MUSYC survey, which is optimized for the study ...
