NuSTAR and AstroSat observations of GX 91: Spectral and temporal studies
Neal Titus Thomas, S. B. Gudennavar, S. G. Bubbly
We have studied the spectro-temporal properties of the neutron star low mass X-ray binary GX 91 using data from \textit{NuSTAR/FPM} and \textit{AstroSat/SXT} and \textit{LAXPC}.…
Spectro-temporal and Type I X-ray burst analysis of GX 31 using AstroSat observations
Neal Titus Thomas, S. B. Gudennavar, S. G. Bubbly
GX 31, an atoll type neutron star low-mass X-ray binary, was observed four times by Soft X-ray Telescope and The Large Area X-ray Proportional Counters on-board \textit{AstroSat…
Spectral characteristics of the black hole binary 4U 1957+115: A multi-mission perspective
Sneha Prakash Mudambi, S. B. Gudennavar, R. Misra +1
We report spectral analysis of the persistent black hole X-ray binary, 4U 1957+115, using AstroSat, Swift and NuSTAR observations carried out between 2016-2019. Modelling with a di…
Spectral properties of soft X-ray transient MAXI J0637430 using AstroSat
Neal Titus Thomas, Shivappa B. Gudennavar, Ranjeev Misra +1
Soft X-ray transients are systems that are detected when they go into an outburst, wherein their X-ray luminosity increases several orders of magnitude. These outbursts are markers…
Estimation of the black hole spin in LMC X-1 using AstroSat
Sneha Prakash Mudambi, A. Rao, S. B. Gudennavar +2
LMC X-1, a persistent, rapidly rotating, extra-galactic, black hole X-ray binary (BHXB) discovered in 1969, has always been observed in its high soft state. Unlike many other BHXBs…
A stochastic propagation model to the energy dependent rapid temporal behaviour of Cygnus X-1 as observed by AstroSat in the hard state
Bari Maqbool, M. Sneha Prakash, R. Misra +8
We report the results from analysis of six observations of Cygnus X-1 by Large Area X-ray Proportional Counters (LAXPC) and Soft X-ray Telescope (SXT) on-board AstroSat, when the s…
A study of the star forming regions in the spiral galaxy NGC 2336 using the Ultraviolet Imaging Telescope (UVIT)
P. T. Rahna, M. Das, Jayant Murthy +2
We present a far-UV (FUV) and near-UV (NUV) imaging study of recent star formation in the nearby spiral galaxy NGC 2336 using the Ultraviolet Imaging Telescope (UVIT). NGC 2336 is…
Investigating the In-Flight Performance of the UVIT Payload on ASTROSAT
P. T. Rahna, Jayant Murthy, M. Safonova +3
We have studied the performance of the Ultraviolet Imaging Telescope payload on AstroSat and derived a calibration of the FUV and NUV instruments on board. We find that the sensiti…
JUDE: An Ultraviolet Imaging Telescope Pipeline
Jayant Murthy, P. T. Rahna, Firoza Sutaria +3
The Ultraviolet Imaging Telescope (UVIT) was launched as part of the multi-wavelength Indian ASTROSAT mission on 28 September, 2015 into a low Earth orbit. A 6-month performance ve…
Photometric Identification of Objects from Galaxy Evolution Explorer Survey and Sloan Digital Sky Survey
K. Preethi, S. B. Gudennavar, S. G. Bubbly +2
We have used GALEX and SDSS observations to extract 7 band photometric magnitudes for over 80,000 objects in the vicinity of the North Galactic Pole. Although these had been identi…
