Abstract: Since first confirmation in December 2019, the novel coronavirus diseases (COVID-19) infected more than 50,000 people and claimed over 2000 lives in Wuhan, China. It was transmitted across the whole country shortly, and now swept the world by causing more 20,000 infections in countries other than China. Using official reported cases and assuming changing reporting ratio, we investigated the early stage of the epidemic of COVID-19 in Wuhan and analysed its transmissibility. We then built up a conceptual model and incorporated the zoonotic introduction, emigration, individual reaction, and governmental action to simulate the trends of the outbreak in Wuhan and predicted the disease would be completely controlled by the end of April under current policies. These studies provide insights into not only the characteristics of COVID-19 itself, but the impact of governmental actions.

 

MIDAS Fellow, Arya Farahi, publishes manuscript on how the age of Dark Matter halos govern their content.

By | News, Research
Dark Matter halos are the most massive gravitationally bound objects in our Universe. These halos host the majority of baryonic matter in the Universe in the form of hot gas and cold stellar phase. Determining how baryons are partitioned into these phases is challenging and requires detailed modeling of galaxy formation and their assembly history. By employing a suite of cosmological simulations, Farahi et al. show that formation time of the same mass halos is strongly correlated with their gas and stellar content. This implies that formation time is one of the key factors that governs the content and form of the Baryons within the dark matter halos. Incorporating this information has the potential to improve our understanding of the fundamental physics of our Universe using galaxy cluster abundance and allows us to gain insight into the matter evolution within these systems.
