Extreme color-magnitude variability: connection to changing-look AGNs
Litao Zhu, Zhongxiang Wang, Alok C. Gupta +5
Context. Changing-look active galactic nuclei (CL-AGNs) challenge the unified model of AGNs and offer key insights into the physics of the accretion processes of super-massive blac…
Detection of actinides in CEMP-rs stars
A. M. Riyas, D. Karinkuzhi, S. Van Eck +4
The carbon-enhanced metal-poor stars with hybrid enrichments of slow- and rapid neutron-capture elements, the so-called CEMP-rs stars, still raise many questions due to their elusi…
Applications of quantum annealing to magnetic dipole hyperfine structure constants: First results beyond energies for atoms
Boni Paul, Subimal Deb, Per Jönsson +2
We report the first results of the magnetic dipole hyperfine structure (HFS) constants of neutral , Li-like , neutral , and Na-like $\mathrm{…
Observational Frontiers in the post-EoR 21-cm Intensity Mapping: Lessons from the SKA Pathfinders
Khandakar Md Asif Elahi, Somnath Bharadwaj, Philip Bull +21
The 21-cm line from neutral hydrogen has long been recognised as a promising tracer of the large-scale structure of the Universe. The line is weak however, making individual galaxy…
On the governing mechanism of unsteadiness in bow shock-induced three-dimensional separation
S. Vayala, K. Ramachandra, K. Abhishek +2
We investigate the driving mechanism of low-frequency unsteadiness in bow shock-turbulent boundary layer interactions due to protuberances. Wind tunnel experiments are conducted at…
Field-like Perturbation Enabled Six-state Readout in Triaxial -|Pt Bi-layers
Aditya A. Wagh, Shwetha G. Bhat, Krishna Jha +2
Understanding current-induced spin-orbit torques provides a route for all-electrical control of antiferromagnetic (AFM) order. Here, we demonstrate the reading of six-state memory…
