Precision Measurement of the Proton Flux in Primary Cosmic Rays from 1 GV to 1.8 TV with the Alpha Magnetic Spectrometer on the International Space Station
Cristina Consolandi
A precision measurement of the proton flux in primary cosmic rays with rigidity from 1 GV to 1.8 TV is presented based on 300 million events. The results show that the proton flux…
The Broadband Spectral Variability of Holmberg IX X-1
D. J. Walton, F. Fuerst, F. A. Harrison +9
We present results from four new broadband X-ray observations of the extreme ultraluminous X-ray source Holmberg IX X-1 ( erg/s), performed by and $N…
Nature of the soft ULX in NGC 247: super-Eddington outflow and transition between the supersoft and soft ultraluminous regimes
Hua Feng, Lian Tao, Philip Kaaret +1
We report on XMM-Newton/Chandra/Swift/HST observations of the ultraluminous X-ray source (ULX) in NGC 247, which is found to make transitions between the supersoft ultraluminous (S…
A 78 Day X-ray Period Detected from NGC 5907 ULX1 by Swift
D. J. Walton, F. Fuerst, M. Bachetti +12
We report the detection of a day period in the X-ray lightcurve of the extreme ultraluminous X-ray source NGC 5907 ULX1 ( erg s$^{-1…
A broadband X-ray spectral study of the intermediate-mass black hole candidate M82 X-1 with NuSTAR, Chandra and Swift
Murray Brightman, Fiona A. Harrison, Didier Barret +8
M82 X-1 is one of the brightest ultraluminous X-ray sources (ULXs) known, which, assuming Eddington-limited accretion and other considerations, makes it one of the best intermediat…
