Halo spin and orientation in Interacting Dark Matter Dark Energy Cosmology
Guandi Zhao, Jiajun Zhang, Peng Wang +1
In recent years, the interaction between dark matter (DM) and dark energy (DE) has become a topic of interest in cosmology. Interacting dark matter-dark energy (IDE) models have a…
Forecast measurement of the 21 cm global spectrum from Lunar orbit with the Vari-Zeroth-Order Polynomial (VZOP) method
Tianyang Liu, Jiajun Zhang, Yuan Shi +7
The cosmic 21 cm signal serves as a crucial probe for studying the evolutionary history of the Universe. However, detecting the 21 cm signal poses significant challenges due to its…
A Multi-Mechanism Hybrid Model of Peaked-Spectrum Radio Sources
Guang-Chen Sun, Yichao Li, Furen Deng +6
The peaked-spectrum (PS) sources exhibit turnover characteristics in their broad radio spectra. However, the mechanism underlying this phenomenon remains elusive. The two most comm…
Loop I/NPS morphology predictions in the ultralong-wavelength band
Yanping Cong, Bin Yue, Yidong Xu +3
Loop I/North Polar Spur (NPS) is the giant arc structure above the Galactic plane observed at radio wavelengths ( GHz). There has been long-standing debate about its o…
