Quasars in a Neutral Universe
During the Epoch of Reionization (EoR) primeval galaxies and accreting black holes reionized and reheated the hydrogen in the intergalactic medium (IGM) ending the preceding cosmic `dark ages'. Understanding how reionization occurred and the nature of the early sources that drove it are among the most important open questions in cosmology. The latest cosmic microwave background constraints sugg...

Semi-analytic spectral fitting: simultaneously modelling the mass accumulation and chemical evolution in MaNGA spiral galaxies
We develop a novel semi-analytic spectral fitting approach to quantify the star-formation histories (SFHs) and chemical enrichment histories (ChEHs) of individual galaxies. We construct simple yet general chemical evolution models that account for gas inflow and outflow processes as well as star formation, to investigate the evolution of merger-free star-forming systems. These models are fitted...

Gravitational Wave Memory and its stochastic background
Gravitational wave memory is an outstanding theoretical prediction of general relativity. It may give an insight to fundamental physics such as quantum gravity. Alongwith the development of gravitational wave astronomy, the gravitational wave memory may be detected in the near future. In this talk I will introduce the physical picture of gravitational wave memory and its relation to fundamental...
