The strength of Type-C quasi-periodic oscillations in black hole X-ray binaries correlates with the jet inclination
F. M. Vincentelli, N. Bollemeijer, A. Veledina +10
X-ray quasi-periodic oscillations (QPOs) are a characteristic feature of low-mass X-ray binaries (LMXBs). These oscillations have been studied for decades and revealed a rich and c…
Probing the Strong Gravity Region of Black Holes with eXTP
Qingcui Bu, Cosimo Bambi, Lijun Gou +42
We present the novel capabilities of the enhanced X-ray Timing and Polarimetry (eXTP) mission to study the strong gravity region around stellar-mass black holes in X-ray binary sys…
Type I X-ray Burst Emission Reflected into the Eclipses of EXO 0748-676
Amy H. Knight, Jakob van den Eijnden, Adam Ingram +8
The neutron star X-ray binary, EXO 0748--676, was observed regularly by the Rossi X-ray Timing Explorer (RXTE) and XMM-Newton during its first detected outburst (1985 - 2008). Thes…
Skipping a beat: discovery of persistent quasi-periodic oscillations associated with pulsed fraction drop of the spin signal in M51 ULX-7
Matteo Imbrogno, Sara Elisa Motta, Roberta Amato +24
The discovery of pulsations in (at least) six ultraluminous X-ray sources (ULXs) has shown that neutron stars can accrete at (highly) super-Eddington rates, challenging the standar…
A systematic study of the high-frequency bump in the black-hole low-mass X-ray binary GX 339-4
Yuexin Zhang, Mariano Méndez, Sara E. Motta +8
The high-frequency bump, characterized by a frequency exceeding ~30 Hz, represents a seldom-explored time-variability feature in the power density spectrum (PDS) of black-hole X-ra…
Highly Significant Detection of X-Ray Polarization from the Brightest Accreting Neutron Star Sco X-1
Fabio La Monaca, Alessandro Di Marco, Juri Poutanen +116
The Imaging X-ray Polarimetry Explorer (IXPE) measured with high significance the X-ray polarization of the brightest Z-source Scorpius X-1, resulting in the nominal 2-8 keV energy…
Spectral variability in Swift and Chandra observations of the Ultraluminous source NGC 55 ULX1
F. Pintore, P. Esposito, L. Zampieri +2
NGC 55 ULX1 is a bright Ultraluminous X-ray source located 1.78 Mpc away. We analysed a sample of 20 Swift observations, taken between 2013 April and August, and two Chandra observ…
The aperiodic variability of the Ultraluminous X-ray source in NGC 5408
M. D. Caballero-Garcia, S. E. Motta, T. M. Belloni +1
Ultra-Luminous X-ray sources are accreting black holes that might represent strong evidence of the Intermediate Mass Black Holes (IMBH), proposed to exist by theoretical studies bu…
The spin and orbit of the newly discovered pulsar IGR J17480-2446
A. Papitto, A. D'Ai', S. Motta +5
We present an analysis of the spin and orbital properties of the newly discovered accreting pulsar IGR J17480-2446, located in the globular cluster Terzan 5. Considering the pulses…
The evolution of the high-energy cut-off in the X-Ray spectrum of the GX 339-4 across a hard-to-soft transition
S. Motta, T. Belloni, J. Homan
We report on X-ray observations of the black-hole candidate GX 339-4 during its 2006/2007 outburst. The hardness-intensity diagram of all RXTE/PCA data combined shows a q-shaped tr…
