Abstract The cosmic 21 cm signal serves as a crucial probe for studying the evolutionary history of Universe. However, detecting poses significant challenges due to its extremely faint nature. To mitigate interference from Earth’s radio frequency (RFI), ground and ionospheric effects, Discovering Sky at Longest Wavelength (DSL) project will deploy constellation satellites in Lunar orbit, with high-frequency daughter satellite tasked global dawn reionization era (CD/EoR).We intend employ...
ABSTRACT Detecting the cosmic 21 cm signal from epoch of reionization has always been a difficult task. Although Galactic foreground can be regarded as smooth power-law spectrum, due to chromaticity antenna, additional structure will introduced into global making polynomial fitting algorithm perform poorly. In this paper, we introduce an improved – Vari-Zeroth-Order Polynomial (VZOP) and use it fit simulation data. This is developed for upcoming low-frequency anechoic chamber experiment, yet...
[Formula: see text] (SLTO) ceramics ([Formula: = 0.05, 0.10, 0.15) were prepared with giant dielectric constant by the traditional solid-state method at 1350[Formula: text]C. The temperature dependence of was obtained ranging from 29[Formula: text]C to 500[Formula: and frequency 2 kHz MHz. Two sets relaxation peaks appear in low (region I) high II), respectively. For region I, we conclude that behavior is related oxygen vacancy migration. II, two processes are caused grain boundary for Sr or...
