Axions explain the formation of supermassive black holes at cosmic dawn
Pierre Sikivie, Yuxin Zhao
In a recent paper we pointed out that supermassive black holes, with masses ranging from to form naturally at cosmic dawn if the dark matter is QCD axions…
The nine rings of the galaxy LEDA 1313424
Pierre Sikivie, Yuxin Zhao
The galaxy LEDA 1313424 has recently been discovered by I. Pasha et al. to have nine rings. The authors of the discovery paper interpret the rings to be the result of the passing o…
Supermassive black hole formation in the initial collapse of axion dark matter
Pierre Sikivie, Yuxin Zhao
Axion dark matter thermalizes by gravitational self-interactions and forms a Bose-Einstein condensate. We show that the rethermalization of the axion fluid during the initial colla…
Effects of a dark matter caustic passing through the Oort cloud
Yuxin Zhao, Antonios Kyriazis, Pierre Sikivie
We investigate the effect of a dark matter caustic passing through the Solar System. We find, confirming a previous result, that the Sun tracks the caustic surface for some time. W…
