Viscous Dark Energy In Bianchi Type V Space-Time.
We study the behavior of dark energy (DE) in the scope of anisotropic Bianchi type V (BV) space-time. First we derive Friedmann-Like Equations, then we compare the dark energy equation of state (EoS) parameter for viscous and non-viscous dark energy and make a correspondence between DE and quintessence and phantom descriptions of non-viscous and viscous dark energy and reconstruct the potential of these two scalar fields. The late time behavior of EoS parameter through a thermodynamical study has also been investigated. Finally, we investigate the conditions under which BV space-time can be mapped into the FRW and how the bulk viscose coefficient may affect dark energy EoS parameter of our $\omega\mbox{BV}$ Model with constraints from 28 Hubble parameter, $H(z)$, measurements at intermediate redshifts $0.07\leq z\leq 2.3$.

Keeping up-to-date with research can feel impossible, with papers being published faster than you'll ever be able to read them. That's where Researcher comes in: we're simplifying discovery and making important discussions happen. With over 19,000 sources, including peer-reviewed journals, preprints, blogs, universities, podcasts and Live events across 10 research areas, you'll never miss what's important to you. It's like social media, but better. Oh, and we should mention - it's free.
Researcher displays publicly available abstracts and doesn’t host any full article content. If the content is open access, we will direct clicks from the abstracts to the publisher website and display the PDF copy on our platform. Clicks to view the full text will be directed to the publisher website, where only users with subscriptions or access through their institution are able to view the full article.
