Rebrightenings of gamma-ray burst afterglows from an increasing magnetic inclination angle of a nascent magnetar
M. Xu, J. Li, C. F. Xiao +1
A nascent magnetar, accompanying a gamma-ray burst (GRB) explosion, releases enormous rotational energy via magnetic dipole radiation. The energy loss rate of the magnetar is deter…
Observations of Cygnus X-1 in the MeV band by the INTEGRAL imager
R. Walter, M. Xu
The spectrum of the MeV tail detected in the black-hole candidate Cygnus X-1 remains controversial as it appeared much harder when observed with the INTEGRAL Imager IBIS than with…
Signature of a spin-up magnetar from multi-band afterglow rebrightening of GRB 100814A
Y. B. Yu, Y. F. Huang, X. F. Wu +2
In recent years, more and more gamma-ray bursts with late rebrightenings in multi-band afterglows unveil the late-time activities of the central engines. GRB 100814A is a special o…
Failed Gamma-Ray Bursts: Thermal UV/Soft X-ray Emission Accompanied by Peculiar Afterglows
M. Xu, S. Nagataki, Y. -F. Huang +1
We show that the photospheres of "failed" Gamma-Ray Bursts (GRBs), whose bulk Lorentz factors are much lower than 100, can be outside of internal shocks. The resulting radiation fr…
An Off-Axis Relativistic Jet Model for the Type Ic supernova SN 2007gr
M. Xu, S. Nagataki, Y. F. Huang
We propose an off-axis relativistic jet model for the Type Ic supernova SN 2007gr. Most of the energy ( erg) in the explosion is contained in non-relativistic e…
A new three-parameter correlation for gamma-ray bursts with a plateau phase in the afterglow
M. Xu, Y. F. Huang
Gamma ray bursts (GRBs) have great advantages for their huge burst energies, luminosities and high redshifts in probing the Universe. A few interesting luminosity correlations of G…
Early Rebrightenings of X-ray Afterglows from Ring-Shaped GRB Jets
M. Xu, Y. -F. Huang
Early rebrightenings at a post-burst time of 10^2 - 10^4 s have been observed in the afterglows of some gamma-ray bursts (GRBs). Unlike X-ray flares, these rebrightenings usually l…
