We have carried out a pilot study for the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) ‘All-Sky’ Survey (SASSy), a wide and shallow mapping project at...
A plausible link between dynamically unsettled molecular gas and the radio jet in NGC 6328
We report the detection of outflowing molecular gas at the center of the nearby radio galaxy NGC6328 (z = 0.014), which has a gigahertz-peaked spectrum radio...
Mrk 622 is a Compton thick active galactic nuclei (AGN) and a double-peaked narrow emission line galaxy, thus a dual AGN candidate. In this work, new optical...
A possible origin of the mass-metallicity relation of galaxies
Observations show that galaxies follow a mass-metallicity relation over a wide range of masses. One currently favoured explanation is that less massive galaxies...
A Possible Relationship between Quasars and Clusters of Galaxies
The distribution on the sky of clusters of galaxies shows significant association with relatively nearby, large, active galaxies. The pattern is that of...
A possible shutting-down event of mass accretion in an active galactic nucleus at z ∼ 1.8
We present the discovery of a large gradual apparent fading event in optical and near-infrared wavelengths in a quasar at by a factor of (in optical) over a...
A possible shutting-down event of mass accretion in an active galactic nucleus at z ∼ 1.8
We present the discovery of a large gradual apparent fading event in optical and near-infrared wavelengths in a quasar at $z=1.767$ by a factor of ${\sim}20\!-\...
A possible signature of the influence of tidal perturbations in dwarf galaxy scaling relations
Dwarf galaxies are excellent cosmological probes, because their shallow potential wells make them very sensitive to the key processes that drive galaxy...
