SN 2012ec: Mass of the progenitor from PESSTO follow-up of the photospheric phase
(Oxford University Press, 2015-04)
We present the results of a photometric and spectroscopic monitoring campaign of SN 2012ec, which exploded in the spiral galaxy NGC 1084, during the photospheric phase. The photometric light curve exhibits a plateau with ...
450 d of Type II SN 2013ej in optical and near-infrared
(OXFORD UNIV PRESS, 2016)
We present optical and near-infrared photometric and spectroscopic observations of SN 2013ej, in galaxy M74, from 1 to 450 d after the explosion. SN 2013ej is a hydrogen-rich supernova, classified as a Type IIL due to its ...
BASS. XLII. The Relation between the Covering Factor of Dusty Gas and the Eddington Ratio in Nearby Active Galactic Nuclei
(Wiley, 2023)
Accreting supermassive black holes (SMBHs) located at the centers of galaxies are typically surrounded by large quantities of gas and dust. The structure and evolution of this circumnuclear material can be studied at ...

Estudio de las propiedades físicas del disco de acreción en AGNs, a partir del análisis de las curvas de luz
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - AstronomíaObservatorio Astronómico NacionalFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022-08-10)
Los núcleos activos, presentes en algunas galaxias, se caracterizan fundamentalmente por presentar variabilidad en las emisiones emitidas sobre diferentes rangos del espectro. Para estudiar las propiedades en la variabilidad ...
SN 2015bn: a detailed multi-wavelength view of a nearbysuperluminous supernova
(IOP Publishing, 2016)
We present observations of SN 2015bn (=PS15ae = CSS141223-113342+004332 = MLS150211-113342+004333), a Type I superluminous supernova (SLSN) at redshift z = 0.1136. As well as being one of the closest SLSNe I yet discovered, ...
