In this work, we report the broadband spectral study of this source with the Swift-XRT & NuSTAR observations made during the latest phase of enhanced X-ray emission which started in 2015. During these observations, MXB 1658-298 showed different spectral states and accretion rates. During the observation of 2015, it was in hard state (island state) while during 2016, source was in soft state (banana state). The persistent flux of 2015 observation is an order of magnitude smaller than the 2016 observation. Total one and seven Type-I X-rays bursts were observed during NuSTAR observations of 2015 and 2016 respectively. We will discuss and compare some interesting features observed during recent outburst of the source. |
