    • Study of the circumgalactic environment of the merger system J205724.14 AT z ~ 4.6 using ALMA 
      Fuentealba Fuentes, Melissa Francisca (Universidad de Chile, 2023)
      Comprender cómo evolucionan las galaxias a lo largo del tiempo es la clave para entender cómo crecieron estos sistemas a partir de pequeñas perturbaciones impresas en el fondo cósmico de microondas (CMB) hasta las galaxias ...
    • Super massive black holes and the Central Region in active galactic nuclei 
      Mejía Restrepo, Julián Esteban (Universidad de Chile, 2017)
      Here I present an in-depth study of the central region of active galactic nuclei oriented to improve current mass estimation methods of distant super massive black holes and to infer the physical properties of the gas ...
    • Swift monitoring of NGC 5548: X-ray reprocessing and short-term UV/optical variability 
      McHardy, I. M.; Cameron, D. T.; Dwelly, T.; Connolly, S.; Lira Teillery, Paulina; Emmanoulopoulos, D.; Gelbord, J.; Breedt, E.; Arevalo, P.; Uttley, P. (Royal Astronomical Society, 2014)
      Lags measured from correlated X-ray/UV/optical monitoring of AGN allow us to determine whether UV/optical variability is driven by reprocessing of X-rays or X-ray variability is driven by UV/optical seed photon variations. ...
    • THE MULTIWAVELENGTH SURVEY BY YALE-CHILE (MUSYC): SURVEY DESIGN AND DEEP PUBLIC UBVRIz0 IMAGES AND CATALOGS ... 
      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 ...
    • Twelve years of X-ray and optical variability in the Seyfert galaxy NGC 4051 
      Breedt, E.; McHardy, I. M.; Arévalo, P.; Uttley, P.; Sergeev, S. G.; Minezaki, T.; Yoshii, Y.; Sakata, Y.; Lira Teillery, Paulina; Chesnok, N. G. (2009)
      We discuss the origin of the optical variations in the Narrow line Seyfert 1 galaxy NGC 4051 and present the results of a cross-correlation study using X-ray and optical light curves spanning more than 12 years. The ...
    • Type II Supernovae light curves characterization using Moriya wind acceleration hydrodynamical models 
      Silva Farfán, Javier Ignacio (Universidad de Chile, 2023)
      A pesar de ser el tipo más común de SNe, todavía hay incertidumbre en torno al origen de estos objetos. Las curvas de luz (LC) de las SNe de tipo II se ven afectadas por las propiedades de las estrellas progenitoras. Esto ...
    • Variabilidad de AGN en la era de las grandes Bases de Datos 
      Sánchez Sáez, Paula Andrea (Universidad de Chile, 2019)
      Los núcleos activos de galaxias o AGN por su sigla en inglés, se caracterizan por su continuo variable en el tiempo en cada banda de frecuencias en la que se han estudiado (Peterson, 2001). Sin embargo, aún no entendemos ...
    • WEAK LINE QUASARS AT HIGH REDSHIFT: EXTREMELY HIGH ACCRETION RATES OR ANEMIC BROAD-LINE REGIONS? 
      Lira Teillery, Paulina (The American Astronomical Society, 2010-09-28)
      We present Gemini-North K-band spectra of two representative members of the class of high-redshift quasars with exceptionally weak rest-frame ultraviolet emission lines (WLQs), SDSS J114153.34+021924.3 at z = 3.55 and SDSS ...
