Meng-Xiang Lin "Seeking Solutions for the Hubble Tension"
As the standard paradigm for cosmology, LCDM model is still challenged by more and more precise modern observations. One of the most significant challenges is so-called Hubble tension, the discrepancy between the locally measured Hubble constant $H_0$ and its value inferred from the early Universe Cosmic Microwave Background (CMB) measurements assuming $\Lambda$CDM model. I will provide some thoughts and examples as the possible solutions for the Hubble tension based on my work with collaborators during my PhD, including the Acoustic Dark Energy model, the interaction between dark energy and dark matter, and early modified gravity. The future directions will also be discussed.
