Searching for axion dark matter with MeerKAT Radio Telescope
Yun-Fan Zhou, Nick Houston, Gyula I. G. Jozsa +11
Axions provide a natural and well-motivated dark matter candidate, with the capability to convert directly to photons in the presence of an electromagnetic field. A particularly co…
Constraining cosmological phase transitions with the Parkes Pulsar Timing Array
Xiao Xue, Ligong Bian, Jing Shu +15
A cosmological first-order phase transition is expected to produce a stochastic gravitational wave background. If the phase transition temperature is on the MeV scale, the power sp…
Constraints on the dark matter annihilation from Fermi-LAT observation of M31
Zhengwei Li, Xiaoyuan Huang, Qiang Yuan +1
Gamma-ray is a good probe of dark matter (DM) particles in the Universe. We search for the DM annihilation signals in the direction of the Andromeda galaxy (M31) using 7.5 year Fer…
Statistical interpretation of the spatial distribution of current 130 GeV gamma-ray line signal within the dark matter annihilation scenario
Rui-Zhi Yang, Qiang Yuan, Lei Feng +2
Recently, several groups identified a tentative -ray line signal with energy GeV in the central Galaxy from the Fermi-LAT data. %The morphology study shows that the s…
CosRayMC: a global fitting method in studying the properties of the new sources of cosmic e excesses
Jie Liu, Qiang Yuan, Xiao-Jun Bi +2
Recently PAMELA collaboration published the cosmic nuclei and electron spectra with high precision, together with the cosmic antiproton data updated, and the Fermi-LAT collaboratio…
Constraint on dark matter annihilation with dark star formation using Fermi extragalactic diffuse gamma-ray background data
Qiang Yuan, Bin Yue, Bing Zhang +1
It has been proposed that during the formation of the first generation stars there might be a "dark star" phase in which the power of the star comes from dark matter annihilation.…
Leptonic dark matter annihilation in the evolving universe: constraints and implications
Qiang Yuan, Bin Yue, Xiaojun Bi +2
The cosmic electron and positron excesses have been explained as possible dark matter (DM) annihilation products. In this work we investigate the possible effects of such a DM anni…
Neutrino emission from dark matter annihilation/decay in light of cosmic and data
Jie Liu, Qiang Yuan, Xiaojun Bi +2
A self-consistent global fitting method based on the Markov Chain Monte Carlo technique to study the dark matter (DM) property associated with the cosmic ray electron/positron exce…
A Markov Chain Monte Carlo Study on Dark Matter Property Related to the Cosmic e Excesses
Jie Liu, Qiang Yuan, Xiaojun Bi +2
In this paper we develop a Markov Chain Monte Carlo code to study the dark matter properties in interpreting the recent observations of cosmic ray electron/positron excesses. We as…
Dark matter annihilation and non-thermal Sunyaev-Zel'dovich effect: I. galaxy cluster
Qiang Yuan, Xiaojun Bi, Feng Huang +1
In this work we calculate the Sunyaev-Zel'dovich (SZ) effect due to the from dark matter (DM) annihilation in galaxy clusters. Two candidates of DM particle, (1) the weakl…
