High energy emission from massive stars: the precocious X-Ray recovery of Eta Carinae after January 2009 minimum
Elena Pian, Sergio Campana, Guido Chincarini +7
We observed the massive binary stellar system of Eta Carinae in the 0.3-10 keV energy range with the X-ray Telescope onboard the Swift satellite during the period 15 December 2008…
Variability in the Prompt Emission of Swift-BAT Gamma-Ray Bursts
T. N. Ukwatta, K. S. Dhuga, W. C. Parke +8
We present the results of our study of the variability time scales of a sample of 27 long Swift Gamma-Ray Bursts (GRBs) with known redshifts. The variability time scale can help ou…
Spectral Lags of Gamma-Ray Bursts from Primordial Black Hole (PBH) Evaporations
T. N. Ukwatta, J. H. MacGibbon, W. C. Parke +5
Primordial Black Holes (PBHs), which may have been created in the early Universe, are predicted to be detectable by their Hawking radiation. PBHs with an initial mass of 5.0 * 10^1…
