报告摘要：In my talk, I will present recent results from my group on various aspects of galaxy evolution from the end of epoch of re-ionisation to the present-day Universe. In the first part, I will focus on the dust-obscured galaxy population and their statistical properties. In particular, we have discovered a population of ultra-massive galaxies with a space density which is 2 orders of magnitude larger than previously known over the redshift range 2<z<4. This is consistent with several very recent observational and theoretical studies that highlight the importance of properly accounting for the dusty population which is dominant at the massive end of the galaxy stellar mass function. In the second part, I will showcase a sub-grid interstellar medium model we have developed to predict the far-infrared emission lines for cosmological hydrodynamic simulations. In the third and last part, I will present some results from our ongoing work on the connection between mergers and bars with the triggering of star-formation and AGN activity.

主讲人简介：I received my BSc degree in physics from Zhejiang University in 2005. In 2009, I obtained my PhD from Imperial College London in the UK. From 2009 and 2012, I was a post-doctoral research fellow at the University of Sussex and from 2012 to 2015, I was a research fellow at the University of Durham (both in the UK). From 2015, I was a tenure-track scientist at SRON Netherlands Institute for Space research, and a Rosalind Franklin fellow & assistant professor at the University of Groningen in the Netherlands. In 2019 I was tenured and in 2021 I was promoted to senior scientist at SRON. I focus on statistical galaxy evolution studies in diverse environment across cosmic time and how galaxy evolution connects to the underlying cosmological framework, using large multiwavelength photometric and spectroscopic extragalactic galaxy surveys from the local to the early Universe and state-of-the-art theoretical models of galaxy formation and evolution. In particular, I study the two main physical processes driving galaxy evolution, i.e., star formation and accretion onto supermassive black holes, using multiple observational probes and test galaxy populations (from field galaxies to galaxy clusters). For my work, I have won several fellowships and grants, including a Rosalind Franklin Fellowship and a NWO VIDI grant. Among various panels and committees, I have also served as a Topical Team member for the European Space Agency Voyage 2050 Programme and as a panel member of the European Southern Observatory Observing Programmes Committee. So far I have (co-)authored over 140 original articles published in high-impact international peer-reviewed journals. I am a lead author (defined here as one of the first three authors) on 38 refereed articles. To date I have a total of over 9000 citations and an H-index of 55.
