Identifier: http://hdl.handle.net/1959.14/1248903
Description: There exist conflicting observations on whether or not the environment of broad- and narrowline active galatic nuclei (AGN) differ and this consequently questions the validity of the AGN unification m ... More

Identifier: http://hdl.handle.net/1959.14/1205096
Description: Recent studies have found that radio-AGN selected by radio-loudness show little difference in terms of their host galaxy properties when compared to non-AGN galaxies of similar stellar mass and redshi ... More

Identifier: http://hdl.handle.net/1959.14/1202506
Description: Context: The mechanism of radio emission in radio-quiet (RQ) active galactic nuclei (AGNs) is still debated and might arise from the central AGN, from star formation activity in the host, or from eith ... More

Identifier: http://hdl.handle.net/1959.14/1204752
Description: In order to reproduce the high-mass end of the galaxy mass distribution, some process must be responsible for the suppression of star formation in the most massive of galaxies. Commonly active galacti ... More
