Discovery of a Supercluster at 0.91 and Testing the CDM Cosmological Model
J. -W. Kim, M. Im, S. -K. Lee +13
The CDM cosmological model successfully reproduces many aspects of the galaxy and structure formation of the universe. However, the growth of large-scale structures (LSSs) in th…
Mergers as triggers for nuclear activity: A near-IR study of the close environment of AGN in the VISTA-VIDEO survey
Marios Karouzos, Matt J. Jarvis, David Bonfield
There is an ongoing debate concerning the driver of nuclear activity in galaxies, with AGN either being triggered by major or minor galactic mergers or, alternatively, through secu…
Star-formation in the host galaxies of radio-AGN
Marios Karouzos, Markos Trichas, Myungshin Im +2
There exist strong evidence supporting the co-evolution of central supermassive black holes and their host galaxies. It is however still unclear what the exact role of nuclear acti…
Radio-AGN in the AKARI-NEP field and their role in the evolution of galaxies
Marios Karouzos, Myungshin Im, the AKARI-NEP team
Radio-loud active galaxies have been found to exhibit a close connection to galactic mergers and host galaxy star-formation quenching. We present preliminary results of an optical…
Where the active galaxies live: a panchromatic view of radio-AGN in the AKARI-NEP field
Marios Karouzos, Myungshin Im, Markos Trichas +1
We study the host galaxy properties of radio sources in the AKARI-North Ecliptic Pole (NEP) field, using an ensemble of multi-wavelength datasets. We identify both radio-loud and r…
AGN jets under the microscope: A divide?
Marios Karouzos, Silke Britzen, Arno Witzel +2
A new paradigm for active galactic jet kinematics has emerged through detailed investigations of BL Lac objects using very long baseline radio interferometry. In this new scheme, m…
