A jet model for the fast IR variability of the black hole X-ray binary GX 339-4
Julien Malzac, Maithili Kalamkar, Federico Vincentelli +16
Using the simultaneous Infra-Red (IR) and X-ray light curves obtained by Kalamkar et al. (2016), we perform a Fourier analysis of the IR/X-ray timing correlations of the black hole…
Modelling the cross-spectral variability of the black hole binary MAXI J1659-152 with propagating accretion rate fluctuations
S. Rapisarda, A. Ingram, M. Kalamkar +1
The power spectrum of the X-ray fluctuations of accreting black holes often consists of two broad humps. We quantitatively investigate the hypothesis that the lower frequency hump…
Detection of the first infra-red quasi periodic oscillation in a black hole X-ray binary
M. Kalamkar, P. Casella, P. Uttley +5
We present analysis of fast variability of Very Large Telescope/ISAAC (infra-red), \textit{XMM-Newton}/OM (optical) and EPIC-pn (X-ray), and RXTE/PCA (X-ray) observations of the bl…
Swift X-ray Telescope study of the Black Hole Binary MAXI J1659-152: Variability from a two component accretion flow
M. Kalamkar, M. van der Klis, L. Heil +1
We present an energy dependent X-ray variability study of the 2010 outburst of the black hole X-ray binary MAXI J1659-152 with the Swift X-ray Telescope (XRT). The broad-band noise…
Are spectral and timing correlations similar in different spectral states in black hole X-ray binaries?
M. Kalamkar, M. T. Reynolds, M. van der Klis +2
We study the outbursts of the black hole X-ray binaries MAXI J1659-152, SWIFT J1753.5--0127 and GX 339-4 with the Swift X-ray Telescope. The bandpass of the X-ray Telescope has acc…
The physics of accretion-ejection with LOFT
P. Casella, R. Fender, M. Coriat +29
This is a White Paper in support of the mission concept of the Large Observatory for X-ray Timing (LOFT), proposed as a medium-sized ESA mission. We discuss the potential of LOFT f…
Discovery of twin kHz quasi periodic oscillations in the low mass X-ray binary XTE J1701-407
Devraj D. Pawar, Maithili Kalamkar, Diego Altamirano +5
We report the discovery of kHz quasi periodic oscillations (QPOs) in three Rossi X-ray Timing Explorer observations of the low mass X-ray binary (LMXB) XTE J1701-407. In one of the…
Swift XRT Timing Observations of the Black-Hole Binary SWIFTJ1753.5-0127: Disk-Diluted Fluctuations in the Outburst Peak
Maithili Kalamkar, Michiel van der Klis, Phil Uttley +2
After a careful analysis of the instrumental effects on the Poisson noise to demonstrate the feasibility of detailed stochastic variability studies with the Swift X-Ray Telescope (…
The faint "heartbeats" of IGR J17091-3624: an exceptional black-hole candidate
D. Altamirano, T. Belloni, M. Linares +9
We report on the first 180 days of RXTE observations of the outburst of the black hole candidate IGR J17091-3624. This source exhibits a broad variety of complex light curve patter…
Possible twin kHz Quasi Periodic Oscillations in the accreting millisecond X-ray Pulsar IGR J17511-3057
Maithili Kalamkar, Diego Altamirano, M. van der Klis
We report on the aperiodic X-ray timing and color behavior of the accreting millisecond X-ray pulsar (AMXP) IGR J17511-3057, using all the pointed observations obtained with the Ro…
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…
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…
