Constraining inhomogeneous energy injection from annihilating dark matter and primordial black holes with 21-cm cosmology
Yitian Sun, Joshua W. Foster, Julian B. Muñoz
The cosmic dawn 21-cm signal is a highly sensitive probe of any process which injects energy into the intergalactic medium, enabling novel searches for anomalous energy injection b…
Inhomogeneous Energy Injection in the 21-cm Power Spectrum: Sensitivity to Dark Matter Decay
Yitian Sun, Joshua W. Foster, Hongwan Liu +2
The 21-cm signal provides a novel avenue to measure the thermal state of the universe during cosmic dawn and reionization (redshifts ), and thus to probe energy injecti…
Looking in the axion mirror: An all-sky analysis of stimulated decay
Yitian Sun, Katelin Schutz, Harper Sewalls +2
Axion dark matter (DM) produces echo images of bright radio sources via stimulated decay. These images appear as a faint radio line centered at half the axion mass, with the line w…
Modeling early-universe energy injection with Dense Neural Networks
Yitian Sun, Tracy R. Slatyer
We show that Dense Neural Networks can be used to accurately model the cooling of high-energy particles in the early universe, in the context of the public code package DarkHistory…
Axion dark matter-induced echo of supernova remnants
Yitian Sun, Katelin Schutz, Anjali Nambrath +2
Axions are a theoretically promising dark matter (DM) candidate. In the presence of radiation from bright astrophysical sources at radio frequencies, nonrelativistic DM axions can…
