Dissecting the active galactic nucleus in Circinus - I. Peculiar mid-IR morphology explained by a dusty hollow cone
(Oxford university press, 2017)
Recent high angular resolution observations resolved for the first time the mid-infrared (MIR) structure of nearby active galactic nuclei (AGN). Surprisingly, they revealed that a major fraction of their MIR emission comes ...
BUDHIES – III: the fate of HI and the quenching of galaxies in evolving environments
(Oxford Univ Press, 2016)
In a hierarchical Universe clusters grow via the accretion of galaxies from the field, groups and even other clusters. As this happens, galaxies can lose and/or consume their gas reservoirs via different mechanisms, ...
Properties of galaxies with ring structures
(EDP Sciences, 2021-09)
Aims: We present a statistical analysis of different characteristics of ringed spiral galaxies with the aim of assessing the effects of rings on disk galaxy properties. Methods: We built a catalog of ringed galaxies from ...

Masas de agujeros negros en galaxias narrow line seyfert 1
(2011)
En este trabajo se presentan los fundamentos básicos sobre el fenómeno de actividad nuclear en galaxias. Se hace un particular énfasis en los núcleos activos del tipo Narrow Line Seyfert 1 (NLS1). Se describen los métodos ...
Estudio infrarrojo de la galaxia activa NGC 2992
(2023)
NGC 2992 es una galaxia que posee un núcleo activo de tipo Seyfert vista desde el Hemisferio Sur. Diferentes estudios sobre esta galaxia han presentado perfiles asimétricos, curvas distintas de velocidad radial de gas, ...
Análise da anisotropia orbital de populações de galáxias em aglomerados
(Universidade Federal de Santa MariaBrasilFísicaUFSMPrograma de Pós-Graduação em FísicaCentro de Ciências Naturais e Exatas, 2023-07-28)
In this work we analyze the velocity anisotropy profiles β(r) of the star-forming (SF), transition
(T), AGN, and quiescent (Q) galaxy populations belonging to gaussian clusters in
order to study the impact of a galaxy’s ...
A New Collisional Ring Galaxy at z = 0.111: Auriga's Wheel
(2011)
We report the serendipitous discovery of a collision ring galaxy, identified as 2MASX J06470249+4554022, which we have dubbed 'Auriga's Wheel', found in a SUPRIME-CAM frame as part of a larger Milky Way survey. This peculiar ...
Los pársecs más internos de las galaxias activas /
(2010-12)
Los núcleos activos de galaxias o AGNs son considerados los objetos más luminosos del Universo. Estos emiten cantidades importantes de energía a lo largo de todo el espectro electromagnético, la cual es capaz de superar ...
Variable broad lines and outflow in the weak blazar PBC J2333.9-2343
(Oxford University Press, 2018-08)
PBC J2333.9-2343 is a peculiar active nucleus with two giant radio lobes and a weak blazarlike nucleus at their centre. In this work we show new optical, ultraviolet (UV), and X-ray data taken from the San Pedro Mártir ...
