Constraints on Spatial Curvature and Dark Energy Dynamics in the CDM Model from DESI DR1 and DR2
Manish Yadav, Archana Dixit, M. S. Barak +1
In this study, we investigate the CDM dynamical dark energy model with spatial curvature utilizing the recently released DESI Collaboration data (DR1 and DR2) in conjunction wit…
The Indian Pulsar Timing Array Data Release 2: II. Customised Single-Pulsar Noise Analysis and Noise Budget
K. Nobleson, Churchil Dwivedi, Shantanu Desai +33
We present the results of customised single-pulsar noise analysis of 27 millisecond pulsars from the second data release of the Indian Pulsar Timing Array (InPTA-DR2). We model var…
Effective CDM model emerging from under a special EOS limit in symmetric cosmology with Bayesian and ANN observational constraints
Anil Kumar Yadav, S. H. Shekh, N. Myrzakulov +3
In this work, we investigate the cosmological consequences of an effective CDM model emerging from the more general gravity theory under the special equation-of-state c…
Revisiting wideband pulsar timing measurements
Abhimanyu Susobhanan, Avinash Kumar Paladi, Réka Desmecht +28
In the wideband paradigm of pulsar timing, the time of arrival of a pulsar pulse is measured simultaneously with the corresponding dispersion measure from a frequency-resolved inte…
Beyond CDM: Exploring a Dynamical Cosmological Constant Framework Consistent with Late-Time Observations
Archana Dixit, Manish Yadav, Anirudh Pradhan +1
In this work, we investigate a cosmological scenario with a time-dependent cosmological constant (t) within the spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) framewo…
Investigating the CDM Model with Latest DESI BAO Observations
Manisg Yadav, Archana Dixit, M. S. Barak +1
In this study, we explore the impact of various combinations of CMB-independent datasets, including the recent DESI BAO measurements, on the equation of state (EoS) of dark energy…
