Cyclotron Line Variability and Accretion Dynamics in Vela X-1
Mohammed Tobrej, Binay Rai, Manoj Ghising +1
We present a comprehensive analysis of Vela X-1 using two new NuSTAR observations, placed in the context of four earlier datasets obtained between 2012 and 2020. The energy-resolve…
Spectral-Timing Evolution of a Black hole X-ray binary Swift J1727.8-1613: Linking Disk Reflection and Type-C QPO Frequency During the 2023 Outburst
Manoj Ghising, Nirpat Subba, Mohammed Tobrej +2
We present a comprehensive spectral-timing analysis of a BHXB Swift J1727.81613 during its 2023 outburst, using five pointed \textit{NuSTAR} observations sampling the luminous h…
Spectro-timing analysis of Be X-ray pulsar SMC X-2 during the 2022 outburst
Mohammed Tobrej, Binay Rai, Manoj Ghising +2
We present broadband X-ray observations of the High Mass X-ray Binary (HMXB) pulsar SMC X-2, using concurrent NuSTAR and NICER observations during its 2022 outburst. The source is…
NuSTAR detection of a broad absorption line in IGR J06074+2205
Mohammed Tobrej, Binay Rai, Manoj Ghising +1
We present the broadband X-ray study of the BeXRB pulsar IGR J06074+2205 using NuSTAR observations. The temporal and spectral characteristics of the source are investigated. We det…
The ongoing spin-down episode of 4U 1626-67
Mohammed Tobrej, Ruchi Tamang, Binay Rai +2
We report the X-ray characteristics of the persistent X-ray pulsar 4U 1626-67 using simultaneous NuSTAR and NICER observations. The X-ray pulsar 4U 1626-67 has just encountered a t…
Luminosity dependent cyclotron line in Swift J1626.6-5156
Binay Rai, Biswajit Paul, Mohammed Tobrej +3
We studied the timing and spectral properties of the Be/X-ray pulsar Swift J1626.6-5156 using the \emph{NICER} observations of its 2021 outburst. The most important observation is…
Long-term evolution of Cyclotron Line energy in an eclipsing pulsar 4U 1538-522
Ruchi Tamang, Manoj Ghising, Mohammed Tobrej +2
We present the timing and spectral analysis of the HMXB source 4U 1538-522 using NuSTAR observations. One of the observations partially covers the X-ray eclipse of the source along…
Low luminosity observation of BeXRB source IGR J21347+4737
Manoj Ghising, Ruchi Tamang, Binay Rai +2
In this paper, we report the results of the detailed temporal and spectral studies of the BeXRB J21347+4737 based on the data from the NuSTAR and \textit{SWIFT/XRT} in a wide energ…
Spectral study of neutron star low mass X-ray binary source 1A 1744-361
Mohammed Tobrej, Binay Rai, Manoj Ghising +2
We present X-ray observations of the recent outburst of 2022 from the neutron star low mass X-ray binary (LMXB) source 1A 1744-361. Spectral properties of the source have been anal…
Spectral properties of the Be/X-ray pulsar 2S 1553-542 during Type II outbursts
Binay Rai, Biswajit Paul, Mohammed Tobrej +3
We present an extended study of the Be/X-ray pulsar 2S 1553-542 during its Type II outbursts. We have incorporated \emph{NICER, Swift-XRT, RXTE-PCA, \emph{NuSTAR} and FERMI} observ…
