Scalar field dark energy: Insights into cosmological evolution and black hole accretion

M. Koussour, Y. Sekhmani, Alnadhief H. A. Alfedeel +2

We propose a novel approach to parameterize the equation of state for Scalar Field Dark Energy (SFDE) and use it to derive analytical solutions for various cosmological parameters.…

Probing the disc-jet coupling in S4 0954+65, PKS 0903-57, & 4C +01.02 with -rays

Ajay Sharma, Sushanth Reddy Kamaram, Raj Prince +2

We present a comprehensive variability study on three blazars, S4 0954+65, PKS 0903-57, and 4C +01.02 covering a mass range of log(M/M) = 8--9, by using 15 years-lo…

Discovery of a Radiation Component from the Vela Pulsar Reaching 20 Teraelectronvolts

The H. E. S. S. Collaboration, :, F. Aharonian +178

Gamma-ray observations have established energetic isolated pulsars as outstanding particle accelerators and antimatter factories in the Galaxy. There is, however, no consensus rega…

Cosmological implications of the constant jerk parameter in gravity theory

N. Myrzakulov, M. Koussour, Alnadhief H. A. Alfedeel +1

This study delves into modified gravity theories that are equivalent to General Relativity but involve the torsion or non-metricity scalar instead of the curvature scalar. Specific…

The effect of cluster dynamical state on ram-pressure stripping

A. C. C. Lourenço, Y. L. Jaffé, B. Vulcani +14

Theoretical and observational studies have suggested that ram-pressure stripping by the intracluster medium can be enhanced during cluster interactions, boosting the formation of t…
