• Memory effects and entanglement dynamics of finite time acceleration 

  Dubey, Nitesh K; Kolekar, Sanved (American Physical Society, 2026-04-15)

  We construct a smooth trajectory in Minkowski spacetime that is inertial in the asymptotic past and future but undergoes approximately uniform acceleration for a finite duration. In a suitable limit, this trajectory ...
• Probing departures from ΛCDM by late-time datasets 

  Chaudhary, Himanshu; Sharma, Vipin Kumar; Capozziello, Salvatore; Mustafa, Ghulam (American Astronomical Society, 2026-04)

  Observational data play a pivotal role in identifying cosmological models that are both theoretically consistent and empirically viable. In this work, we investigate the level of preference for dynamical dark energy over ...
• Non-Gaussian expansion of Minkowski tensors in redshift space 

  Appleby, S; Pichon, C; Pravabati, C; Pogosyan, Dmitri; Park, C (American Astronomical Society, 2026-04-20)

  This paper focuses on extending the use of Minkowski tensors to analyze anisotropic signals in cosmological data, focusing on those introduced by redshift space distortions. We derive the ensemble average of the two ...
• The evolution of the reconnection flux during the eruption of magnetic flux ropes 

  Maity, Samriddhi Sankar; Chatterjee, Piyali; Sarkar, Ranadeep; Mytheen, Ijas S (American Astronomical Society, 2026-04-01)

  Coronal mass ejections (CMEs) are powerful drivers of space weather, with magnetic flux ropes (MFRs) widely regarded as their primary precursors. However, the variation in the reconnection (RC) flux during the evolution ...
• SN 2017hcc and SN2023usc—A comparative spectroscopic study of type IIn supernovae 

  Sethulakshmi, V; Sutaria, F. K; Sharma, Riddhiman; Ray, A (American Astronomical Society, 2026-04-20)

  We report on a spectroscopic study of the bright, nearby type IIn supernovae SN 2017hcc and SN 2023usc using data obtained from the Himalayan Chandra Telescope. SN 2017hcc is a well-studied event, and our sampling covers ...
