A misfired outburst in the neutron star X-ray binary Centaurus X-4
M. C. Baglio, P. Saikia, D. M. Russell +12
We report on a long-term optical monitoring of the neutron star X-ray binary Centaurus X-4 performed during the last 13.5 years. This source has been in quiescence since its outbur…
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…
NICER uncovers the transient nature of the type-B quasi-periodic oscillation in the black hole candidate MAXI J1348-630
L. Zhang, D. Altamirano, P. Uttley +13
We present a systematic spectral-timing analysis of a fast appearance/disappearance of a type-B quasi-periodic oscillation (QPO), observed in four NICER observations of MAXI J1348-…
A Machine Learning Approach For Classifying Low-mass X-ray Binaries Based On Their Compact Object Nature
R. Pattnaik, K. Sharma, K. Alabarta +5
Low Mass X-ray binaries (LMXBs) are binary systems where one of the components is either a black hole or a neutron star and the other is a less massive star. It is challenging to u…
NICER observations reveal that the X-ray transient MAXI J1348-630 is a Black Hole X-ray binary
L. Zhang, D. Altamirano, V. A. Cuneo +16
We studied the outburst evolution and timing properties of the recently discovered X-ray transient MAXI J1348-630 as observed with NICER. We produced the fundamental diagrams commo…
X-ray Spectral and Timing evolution of MAXI J1727-203 with NICER
K. Alabarta, D. Altamirano, M. Méndez +16
We present a detailed X-ray spectral and variability study of the full 2018 outburst of MAXI J1727-203 using NICER observations. The outburst lasted approximately four months. Spec…
