A key challenge in understanding the feedback mechanism of active galactic nucleus (AGN) in Brightest Cluster Galaxies (BCGs) is the inherent rarity of catching an AGN during its strong outburst phase. This is exacerbated by the ambiguity of differen... Read More about Hiding in plain sight – recovering clusters of galaxies with the strongest AGN in their cores.

A Mechanism for stimulating AGN feedback by lifting gas in massive galaxies (2016)
Journal Article

Observation shows that nebular emission, molecular gas, and young stars in giant galaxies are associated with rising X-ray bubbles inflated by radio jets launched from nuclear black holes. We propose a model where molecular clouds condense from low-e... Read More about A Mechanism for stimulating AGN feedback by lifting gas in massive galaxies.

Hyper-luminous infrared galaxies (HyLIRGs) lie at the extreme luminosity end of the IR galaxy population with LIR > 1013 L⊙. They are thought to be closer counterparts of the more distant sub-millimeter galaxies, and should therefore be optimal targe...

Cold, clumpy accretion onto an active supermassive black hole (2016)
Journal Article

Supermassive black holes in galaxy centres can grow by the accretion of gas, liberating energy that might regulate star formation on galaxy-wide scales. The nature of the gaseous fuel reservoirs that power black hole growth is nevertheless largely un... Read More about Cold, clumpy accretion onto an active supermassive black hole.

The ΛCDM cosmological model successfully reproduces many aspects of the galaxy and structure formation of the universe. However, the growth of large-scale structures (LSSs) in the early universe is not well tested yet with observational data. Here, w...
