A Compton polarimeter using scintillators read out with MPPCs through Citiroc ASIC
Rakhee Kushwah, Nirmal K. Iyer, Mózsi Kiss +2
In recent years, a number of purpose-built scintillator-based polarimeters have studied bright astronomical sources for the first time in the hard X-ray band (tens to hundreds of k…
AstroSat view of MAXI J1535-571: broadband spectro-temporal features
Sreehari H., Ravishankar B. T., Nirmal Iyer +4
We present the results of Target of Opportunity (ToO) observations made with AstroSat of the newly discovered black hole binary MAXI J1535-571. We detect prominent C-type Quasi-per…
LAXPC / AstroSat Study of ~ 1 and ~ 2 mHz Quasi-periodic Oscillations in the Be/X-ray Binary 4U 0115+63 During its 2015 Outburst
Jayashree Roy, P. C. Agrawal, N. K. Iyer +13
The Be X-ray Binary 4U 0115+63 was observed by Large Area X-ray Proportional Counter (LAXPC) instrument on AstroSat on 2015 October 24 during the peak of a giant Type II outburst.…
Gamma-ray burst localisation strategies for the SPHiNX hard X-ray polarimeter
L. Heckmann, N. K. Iyer, M. Kiss +2
SPHiNX is a proposed gamma-ray burst (GRB) polarimeter mission operating in the energy range 50-600 keV with the aim of studying the prompt emission phase. The polarisation sensiti…
