Probing the shot behaviour in Cygnus X-1 using simultaneous AstroSat-NICER observation
Yash Bhargava, Nandini Hazra, A. R. Rao +4
We analyse the aperiodic flaring features, also known as shots, observed in Cyg X-1 in the 0.1-80 keV energy band using a 6.39 ks simultaneous observation with AstroSat and NICER.…
Accreting on the edge: a luminosity-dependent cyclotron line in the Be/X-ray Binary 2S 1553-542 accompanied by accretion regimes transition
Christian Malacaria, Yash Bhargava, Joel B. Coley +15
Accreting X-ray pulsars (XRPs) undergo luminous X-ray outbursts during which the luminosity-dependent spectral and timing features of the neutron star's emission can be analyzed in…
A timing-based estimate of the spin of the black hole in MAXI J1820+070
Yash Bhargava, Tomaso Belloni, Dipankar Bhattacharya +2
MAXI J1820+070 (ASSASN-18ey) is a Black hole X-ray binary discovered in 2018. The brightness of the source triggered multi-wavelength campaigns of this source from different observ…
Spectro-timing analysis of MAXI J1535-571 using AstroSat
Yash Bhargava, Tomaso Belloni, Dipankar Bhattacharya +1
We report the results of the analysis of an AstroSat observation of the Black Hole candidate MAXI J1535-571 during its Hard Intermediate state. We studied the evolution of the spec…
Explaining the asymmetric line profile in Cepheus X-4 with spectral variation across pulse phase
Yash Bhargava, Varun Bhalerao, Ralf Ballhausen +4
The high mass X-ray binary Cep X-4, during its 2014 outburst, showed evidence for an asymmetric cyclotron line in its hard X-ray spectrum. The 2014 spectrum provides one of the cle…
A precise measurement of the orbital period parameters of Cygnus X-3
Yash Bhargava, A. R. Rao, K. P. Singh +9
We present X-ray light curves of Cygnus X-3 as measured by the recently launched AstroSat satellite. The light curve folded over the binary period of 4.8 hours shows a remarkable s…
