Current Status of the Hubble Tension

Dear Colleagues,

In the age of precision cosmology, advancements in measuring the Hubble Tension have been remarkable. However, over the past decade, a notable disparity has arisen between the values obtained using the Planck Satellite and those predicted via Type Ia supernovae analysis from the SH0ES Collaboration. This five-sigma inconsistency, termed “Hubble Tension” has garnered significant attention due to the unexpected correlation between the Hubble constant and the redshift of the source used for its determination. Various explanations, ranging from astrophysical phenomena like redshift evolution to conjectures about new physics in the evolution of the Universe, have been proposed.

This Special Issue aims to offer a comprehensive overview of the Hubble Tension, encompassing both data analysis and theoretical models aimed towards resolving it. Central to this collection is the exploration of model testing, crucial for identifying the most promising theoretical avenues. Manuscripts in the form of letters, regular articles, and topical reviews are encouraged, covering diverse aspects of this Special Issue theme. Priority will be given to submissions addressing the physics of dark energy/dark matter interaction, modified gravity formulations, and early-universe dark energy.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Universe is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
