    • Near infrared variability of obscured and unobscured X-Ray selected AGN in the Cosmos field 
      Sánchez, P.; Lira Teillery, Paulina; Cartier Ugarte, Regis; Pérez, V.; Miranda, N.; Yovaniniz, C.; Arévalo, P.; Milvang Jensen, B.; Fynbo, J.; Dunlop, J.; Coppi, P.; Marchesi, S. (IOP Publishing Ltd., 2017)
      We present our statistical study of near-infrared (NIR) variability of X-ray-selected active galactic nuclei (AGNs) in the COSMOS field, using UltraVISTA data. This is the largest sample of AGN light curves in YJHK(s) ...
    • Persistent Cii Absorption In the Normal TYPE Ia Supernova 2002fk∗ 
      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. ...
