Exploring non-cold dark matter in a scenario of dynamical dark energy with DESI DR2 data
Tian-Nuo Li, Peng-Ju Wu, Guo-Hong Du +3
Recent observations of DESI hint that dark matter (DM) may not be cold but have a non-zero equation of state (EoS) parameter, and that dark energy (DE) may not be a cosmological co…

Testing the cosmic distance duality relation with baryon acoustic oscillations and supernovae data
Tian-Nuo Li, Guo-Hong Du, Peng-Ju Wu +3
One of the most fundamental relationships in modern cosmology is the cosmic distance duality relation (CDDR), which describes the relationship between the angular diameter distance…

The Multi-Messenger Astroparticle Physics: the First Constraint on Light Millicharged Dark Matter via Time-Delay Analysis of GRB GW170817A
Wenxing Zhang, Junle Pei, Xin Zhang +1
The multi-messenger astroparticle physics provides a new approach to probe the new physics beyond the Standard Model. We propose to probe the light dark matter which can interact w…
