Hard X-Ray Focal-Plane Compton Spectro-Polarimeter: Detector Development and Sensitivity Evaluation
Abhay Kumar, Tanmoy Chattopadhyay, Santosh V. Vadawale +1
The scientific potential of X-ray polarimetry has long been recognized, yet the challenges of measuring polarization have left it largely unexplored, mainly in the hard X-ray regim…
Multi-Wavelength Diagnostics of Pre-Flare Evolution with Aditya-L1: From the Solar Chromosphere to the Corona
Adithya H. N., Sreejith Padinhatteeri, Soumya Roy +13
The pre-flare phase of solar flares provides important insight into the processes that drive active regions toward instability. We investigate chromospheric pre-flare activity usin…
Can We Find the Emission Mechanism Behind the Extremely Bright GRB 230812B?
Utkarsh Pathak, Sameer K. Patil, Hitesh Tanenia +23
GRB 230812B is a bright long-duration GRB with a luminous, long-lived afterglow and an AstroSat/CZTI polarization measurement during the prompt phase, enabling a joint study of its…
Chhavi: A Python Tool for Converting RAMSES Outputs to VTKHDF for High-Fidelity AMR Visualization
Hemangi C. Varkal, Shubhankar R. Gharote, Munn Vinayak Shukla +1
RAMSES is an adaptive mesh refinement (AMR) astrophysical simulation code that generates high-resolution multiscale data. However, its native binary output format is not directly c…
Development of a one-dimensional position sensitive detector for Compton X-ray polarimeters
Abhay Kumar, Santosh V. Vadawale, N. P. S. Mithun +4
The scientific potential of X-ray polarimetry has long been recognized, but the challenges in measuring polarization have left it largely unexplored, particularly in the hard X-ray…
Star formation efficiency and scaling relations in parsec-scale cluster-forming clumps
V. Rawat, M. R. Samal, A. Zavagno +5
Numerical simulations predict that clumps (1 pc) should form stars at high efficiency to produce bound star clusters. We conducted a statistical study of 17 nearby cluster-fo…
