The identification of MAXI J1659-152 as a black hole candidate
M. Kalamkar, J. Homan, D. Altamirano +3
We report on the analysis of all 65 pointed Rossi X-ray Timing Explorer observations of the recently discovered soft X-ray transient MAXI J1659-152 (initially referred to as GRB 10…
The return of the bursts: Thermonuclear flashes from Circinus X-1
M. Linares, A. Watts, D. Altamirano +14
We report the detection of 15 X-ray bursts with RXTE and Swift observations of the peculiar X-ray binary Circinus X-1 during its May 2010 X-ray re-brightening. These are the first…
Evolution of the radio - X-ray coupling throughout an entire outburst of Aquila X-1
J. C. A. Miller-Jones, G. R. Sivakoff, D. Altamirano +18
The 2009 November outburst of the neutron star X-ray binary Aquila X-1 was observed with unprecedented radio coverage and simultaneous pointed X-ray observations, tracing the radio…
The Double-Peaked 2008 Outburst of the Accreting Milli-Second X-ray Pulsar, IGR J00291+5934
F. Lewis, D. M. Russell, P. G. Jonker +18
In August 2008, the accreting milli-second X-ray pulsar (AMXP), IGR J00291+5934, underwent an outburst lasting ~ 100 days, the first since its discovery in 2004. We present data fr…
Type I X-ray bursts and burst oscillations in the accreting millisecond X-ray pulsar IGR J17511-3057
D. Altamirano, A. Watts, M. Linares +3
We report the discovery of burst oscillations at the spin frequency in ten thermonuclear bursts from the accreting millisecond X-ray pulsar (AMXP) IGR J17511-3057. The burst oscill…
Discovery of an accreting millisecond pulsar in the eclipsing binary system Swift J1749.4-2807
D. Altamirano, Y. Cavecchi, A. Patruno +12
We report on the discovery and the timing analysis of the first eclipsing accretion-powered millisecond X-ray pulsar (AMXP): SWIFT J1749.4-2807. The neutron star rotates at a frequ…
