Black-hole X-ray binary Swift J1727.81613 shows simultaneous Type-B and Type-C quasi-periodic oscillations across the hard-intermediate and soft-intermediate states
Pei Jin, Mariano Méndez, Federico García +2
We present a timing analysis of \textit{Insight}-HXMT observations of the black-hole X-ray binary Swift J1727.81613 across a bright soft X-ray flare on 2023 September 19 (MJD 60…
Evidence for enhanced mass transfer in the disc preceding the transition to the soft state in MAXI J1820+070
Pengcheng Yang, Guobao Zhang, David M. Russell +6
We investigate the 2018-2019 main outburst and the subsequent mini-outbursts of the black hole low-mass X-ray binary MAXI J1820+070 using optical/ultraviolet data from the Las Cumb…
Fast Transitions of X-ray Variability in the Neutron Star Low Mass X-ray Binary Cygnus X-2
Liang Zhang, Mariano Méndez, Hua Feng +12
We present a spectral-timing analysis of two NICER observations of the weakly magnetized neutron star low-mass X-ray binary Cygnus X-2. During these observations, we detect a rapid…
Detection of a Type-C QPO during the soft-to-hard transition in Swift J1727.8-1613
Maïmouna Brigitte, Noel Castro Segura, Federico García +6
Timing analysis of accreting systems is key to probe the structure and dynamics around compact objects. In Black-Hole Low-Mass X-ray Binaries (BH LMXBs), the compact object accrete…
Timing analysis of the black-hole candidate Swift J1727.8-1613: detection of a dip-like feature in the high-energy cross spectrum
Pei Jin, Mariano Méndez, Federico García +3
We present a timing analysis of observations with the Hard X-ray Modulation Telescope of the black hole X-ray transient Swift J1727.8-1613 during its 2023 outburst. We detect, for…
Evolution of the Comptonizing medium of the black-hole candidate Swift J1727.81613 along the hard to hard-intermediate state transition using NICER
Divya Rawat, Mariano Méndez, Federico García +1
We analyse the properties of the Comptonizing medium in the black-hole X-ray binary Swift J1727.81613 using the time-dependent Comptonization model vkompth, using NICER observat…
