On the origin of the X-ray emission towards the early Herbig Be star MWC 297
Jorick S. Vink, Paul M. O'Neill, Sebastian G. Els +1
We present high resolution AO-corrected coronographic near-infrared imaging on the early-type Herbig Be star MWC 297. X-ray flaring has been reported towards this young object, how…
Long-term Periodicities in the Flux from Low Mass X-ray Binaries
Stefan Dieters, Paul O'Neill, Sean Farrell +1
Using data from the All Sky Monitor (ASM) on the Rossi X-ray Timing Explorer (RXTE) we have searched for long term periodicities in the X-ray flux of GX 1+4, Sco X-2 (GX 349+2), an…
Superorbital Period in the High Mass X-ray Binary 2S 0114+650
S. A. Farrell, R. K. Sood, P. M. O'Neill
We report the detection of a superorbital period in the high-mass X-ray binary 2S 0114+650. Analyses of data from the Rossi X-ray Timing Explorer (RXTE) All-Sky Monitor (ASM) from…
Recurrent ~24 h Periods in RXTE ASM Data
S. A. Farrell, P. M. O'Neill, R. K. Sood
Analysis of data from the Rossi X-ray Timing Explorer satellite's All Sky Monitor instrument for several X-ray binary sources has identified a recurrent \~24 h period. This period…
The relationship between X-ray variability amplitude and black hole mass in active galactic nuclei
Paul M. O'Neill, Kirpal Nandra, Iossif E. Papadakis +1
We have investigated the relationship between the 2-10 keV X-ray variability amplitude and black hole mass for a sample of 46 radio-quiet active galactic nuclei observed by ASCA. T…
