Failed-Transition outbursts in Black hole low-mass X-ray binaries

K. Alabarta, D. Altamirano, M. Méndez +6

Black hole low-mass X-ray binaries (BH LMXBs) evolve in a similar way during outburst. Based on the X-ray spectrum and variability, this evolution can be divided into three canonic…

Kilohertz quasi-periodic oscillations in neutron-star X-ray binaries: Flattening of the lag spectrum with increasing luminosity

Valentina Peirano, Mariano Méndez

We study the energy-dependent time lags and rms fractional amplitude of the kilohertz quasi-periodic oscillations (kHz QPOs) of a group of neutron-star low mass X-ray binaries (LMX…

Spectral and timing evolution of MAXI J1631-479 during the 2018-19 outburst with NICER

Sandeep K. Rout, Mariano Méndez, Tomaso M. Belloni +1

The X-ray transient MAXI J1631-479 went into outburst on 2018 December 21 and remained active for about seven months. Owing to various constraints it was monitored by NICER only du…

A variable corona for GRS 1915+105

Konstantinos Karpouzas, Mariano Méndez, Federico García +4

Most models of the low frequency quasi periodic oscillations (QPOs) in low-mass X-ray binaries (LMXBs) explain the dynamical properties of those QPOs. On the other hand, in recent…

Drifts of the marginally stable burning frequency in the X-ray binaries 4U 1608--52 and Aql X--1

G. C. Mancuso, D. Altamirano, M. Méndez +2

We detect millihertz quasi-periodic oscillations (mHz QPOs) using the Rossi X-ray Time Explorer (RXTE) from the atoll neutron-star (NS) low-mass X-ray binaries 4U 1608--52 and Aql…

A two-component Comptonisation model for the type-B QPO in MAXI J1348-630

Federico García, Mariano Méndez, Konstantinos Karpouzas +3

Spectral-timing analysis of the fast variability observed in X-rays is a powerful tool to study the physical and geometrical properties of the accretion/ejection flows in black-hol…
