Axions are naturally coupled to photons through the Chern-Simons term. This coupling would open a window for us to probe the dark components and the inflation by their imprints on the visible sector. Over the past years, we have explored the cosmological signatures of axionic dark energy, dark matter, and inflaton. The axionic dark energy and dark matter can rotate the plane of polarization of...
Axion-like particles (ALPs) appear in many beyond-the-Standard-Model theories, either as candidatesfor dark matter or as partners of the axion that explains the apparent conservation of charge-parity symmetry, known as the strong CP problem. In the first part of the talk, I will present a novel method for probing ALPs using eclipsing binary systems which can serve as an astrophysical...
I will discuss how temperature observations of neutron stars provide a unique window to explore physics beyond the Standard Model of particle physics. Neutron stars, with their extreme environments, serve as natural laboratories for testing the limits of our physical understanding. The standard cooling theory, which accounts for the cooling of isolated neutron stars through neutrino and...
We show how light axions generic in String Theory provide definitive predictions that are borne out by deep lensing and galaxy formation data from JWST. This wave-like behaviour was predicted by pioneering simulations in Taiwan, with pervasive substructure on the de Broglie scale that is very distinguishable from standard heavy particle CDM. This dark matter solution reinforces the absence of...
I will review the current state of the theories and observations of the primordial black holes (PBHs). In particular, I will discuss how a new window for PBH to become dark matter opens when the memory burden effect acts on the evaporating PBHs.
