Characteristics of the curvature effect of uniform jets or spherical fireballs
Rui-Jing Lu, Yi-Ping Qin
Qin et al. (2004) have derived a formula of count rates based on a model of highly symmetric expanding fireballs, where the Doppler effect is the key factor to be concerned. In thi…
Relationship between different channel light curves of gamma-ray burst pulses shown in aspects other than the pulse width
Yi-Ping Qin
In this paper, we employ the peak count rate{\bf \} and the total count of light curves to study in the corresponding aspects the relationship between different ch…
Formulas for direct determination of real speed in Galactic superluminal sources
Yi-Ping Qin
In this paper we show explicit and direct relations between the expected quantities and the observed quantities for the components of Galactic superluminal sources. Basic formulas…
An Accelerated Expansion Model in the Absence of the Cosmological Constant
Yi-Ping Qin
Based on some observations, the apparent energy, associated with gravity, of vacuums is defined, with that of normal vacuums to be zero and that of the vacuums losing some energy t…
