λ = 2 mm spectroscopy observations toward the circumnuclear disk of NGC 1068
Jianjie Qiu, Jiangshui Zhang, Yong Zhang +2
Aims. We investigate the physical and chemical conditions of molecular gas in the circumnuclear disk (CND) region of NGC 1068. Methods. We carried out a spectral line survey with t…
A Statistical Study of GRB X-ray Flares: Evidence of Ubiquitous Bulk Acceleration in the Emission Region
Lan-Wei Jia, Z. Lucas Uhm, Bing Zhang
When emission in a conical relativistic jet ceases abruptly (or decays sharply), the observed decay light curve is controlled by the high-latitude "curvature effect". Recently, Uhm…
Physical origin of multi-wavelength emission of GRB 100418A and implications for its progenitor
Lan-Wei Jia, Xue-Feng Wu, Hou-Jun LV +2
GRB 100418A is a long burst at z=0.624 without detection of any associated supernova (SN). Its lightcurves in both the prompt and afterglow phases are similar to GRB 060614, a near…
A test of the power law relationship between gamma-ray burst pulse width ratio and energy expected in fireballs or uniform jets
Z. -Y. Peng, Y. -P. Qin, B. -B. Zhang +3
Recently, under the assumption that the Doppler effect of the relativistically expanding fireball surface is important, Qin et al. showed that in most cases the power law relations…
The FWHM of local pulses and the corresponding power-law index of gamma-ray burst FRED pulses
L. -W. Jia, Y. -P. Qin
The FWHM of gamma-ray burst (GRB) pulses is known to be related with energy by a power-law. We wonder if the power-law index is related with the corresponding local pulse width…
Method of determining cosmological parameter ranges with samples of candles with an intrinsic distribution
Yi-Ping Qin, Bin-Bin Zhang, Yun-Ming Dong +8
In this paper, the effect of the intrinsic distribution of cosmological candles is investigated. We find that, in the case of a narrow distribution, the deviation of the observed m…
