A comprehensive study of the nucleus and western hotspot of Pictor A is carried out using AstroSat observations, 13 years of Fermi, and archival Swift observations, along with other published data. We report the first detection of the western hotspot

We report the results of AstroSat observations of GRS 1915$+$105 obtained using 100 ks guaranteed-time (GT) during the soft state. The Color-Color Diagram (CCD) indicates a variability class of $\delta$ with the detection of High Frequency QPO (HFQPO

In this paper, we present the first results obtained using $\sim$ 50 ks observations of the bright low-mass X-ray binary (LMXB) GX 17+2 with Large Area X-ray Proportional Counter (LAXPC) onboard {\it AstroSat}. The source traced out a complete Z-trac

In this paper, we present the first results of spectral and timing properties of the atoll source 4U 1705-44 using $\sim$ 100 ks data obtained with Large Area X-ray Proportional Counter (LAXPC) onboard {\it AstroSat}. The source was in the high-soft

By analyzing the time series of RXTE/PCA data, the nonlinear variabilities of compact sources have been repeatedly established. Depending on the variation in temporal classes, compact sources exhibit different nonlinear features. Sometimes they show

We present the results of analysis of the X-ray transient source MAXI J1836-194 during its outburst in August 2011. MAXI GSC detected the source on 30th August 2011, when it started rising from the quiescence. We have studied the source using the obs

A Solar Low-energy X-ray Spectrometer (SoLEXS), a high spectral resolution (\leq 250 eV at 5.9 keV) instrument with soft X-ray energy coverage (\leq 1.5 keV), is being proposed as an additional payload on-board Aditya-1. The motivation behind this is

We present the results of the analysis of RXTE (Rossi X-ray Timing Explorer) observations of the new x-ray transient, SWIFT J1753.5-0127 during its outburst in July, 2005. The source was caught at the peak of the burst with a flux of 7.19e-09 ergs-s$
