      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 ...
    • A thermal pulse in progress in the nucleus of the LMC planetary nebula N66 
      Peña, M.; Torres Peimbert, S.; Peimbert, M.; Ruiz González, María Teresa; Maza Sancho, José (1994-06-10)
      Optical and spectrophotometric ata, gathered in the 1987-1994 interval, are presented for the planetary nebula N66 (WS 35 or SMP 83) in the Large Magellanic Cloud. These data show that the central star has suffered dramatic ...
    • Three planetary companions around M67 stars 
      Brucalassi, A.; Pasquini, L.; Saglia, R.; Ruiz González, María Teresa; Bonifacio, P.; Bedin, L. R.; Biazzo, K.; Melo, C.; Lovis, C.; Randich, S. (ESO, 2014)
      For the past six years we have carried out a search for massive planets around main sequence and evolved stars in the open cluster M67, using radial velocity (RV) measurements obtained with HARPS at ESO (La Silla), SOPHIE ...
    • Time-dependent behavior and physical conditions of the LMC planetary nebular N66 
      Peña, M.; Peimbert, M.; Torres Peimbert, S.; Ruiz González, María Teresa; Maza, J. (1995-03-01)
      Optical and UV spectrophotometric data for the planetary nebula N66 in the Large Magellanic Cloud gathered in the 1987-1994 interval are analyzed. The central star, which had a featureless weak continuum, has developed ...
    • Transient double-peaked line emission as signatures of accretion events around supermassive black holes 
      Storchi-Bergmann, Thaisa; Ruiz González, María Teresa; Eracleous, Michael (Elsevier Ltd, 1998)
      We discuss the recent appearance of very broad (FWZI∼20000 km s-1) double-peaked Balmer emission lines in the nuclei of the galaxies NGC 1097, Pictor A and M 81. Such profiles are rare, and only found in about 10% of ...
    • A transiting planet among 23 new near-threshold candidates from the OGLE survey⋆ — OGLE-TR-182 
      Pont, F.; Tamuz, O.; Udalski, A.; Mazeh, T.; Bouchy, F.; Melo, C.; Naef, D.; Moutou, C.; Díaz, R.; Gieren, W.; Gillón, M.; Hoyer, Sergio; Kubiak, M.; Mayor, M.; Minniti, D.; Pietrzynski, G.; Queloz, D.; Ramírez, S.; Ruiz González, María Teresa; Santos, N. C.; Soszynski, I.; Szewczyk, O.; Szymanski, M. K.; Udry, S.; Ulaczyk, K.; Wyrzykowski, Ł.; Zoccali, Manuela (Springer Verlag, 2008)
      By re-processing the data of the second season of the OGLE survey for planetary transits and adding new mesurements on the same fields gathered in subsequent years with the OGLE telescope, we have identified 23 new transit ...
    • The Type Ic SN 1990B in NGC 4568 
      Clocchiatti, Alejandro; Suntzeff, Nicholas B.; Phillips, Mark M.; Filippenko, Alexei V.; Turatto, Massimo; Benetti, Stefano; Cappellaro, Enrico; Avilés, Roberto; Covarrubias, Ricardo; DeGiogia Eastwood, K.; Dickinson, Mark.; Gouiffes, Christian; Guhathakurta, Puragra; Hamuy Wackenhut, Mario; Heathcote, Steve R.; Leibundgut, Bruno; Matheson, Thomas; Navarrete, Mauricio; Pérez, M.; Phillips, Andrew; Piemonte, Antonello; Ruiz González, María Teresa; Shields, Joseph C.; Smith, Chris; Spinrad, Hyron; Sturch, Conrad R.; Tyson, J. Anthony; Wells, Lisa (2001-06-01)
      We present a study of the Type Ic supernova (SN) 1990B that includes most of the observations obtained from around the world. The combined data set comprises 84 BV (RI)c photometric points spanning approximately 360 days ...
