Constraints on Annihilating Dark Matter from Gamma-Ray Background-Galaxy Shape Correlations: Model-independent Null Results and Moderate Template-based Signals
Masato Shirasaki, Deheng Song, Oscar Macias +2
The paper uses cross‑correlations between the unresolved gamma‑ray background measured by Fermi‑LAT and galaxy shape data from DES Y3 and DECADE to place limits on dark‑matter anni…

Revisiting axion dark matter with nonlinear transitions
Max Miyazaki, Yuma Narita, Deheng Song +2
Recently, two of the present authors showed that even when the axion momentum is much smaller than its mass, the axion can still behave like radiation if its energy density greatly…

Composite asymmetric dark matter with a dark photon portal: Multimessenger tests
Saikat Das, Ayuki Kamada, Takumi Kuwahara +2
Composite asymmetric dark matter (ADM) is the framework that naturally explains the coincidence of the baryon density and the dark matter density of the Universe. Through a portal…
