keV Warm Dark Matter (ΛWDM) in Agreement with Observations in Tribute to Héctor J. de Vega (2nd Edition)

Dear Colleagues,

In light of the success of the first volume of this Special Issue, titled “keV Warm Dark Matter (ΛWDM) in Agreement with Observations in Tribute to Héctor J. de Vega”, we are publishing this second volume under the same title.

The first volume attracted great interest, as evidenced by its impressive 11 publications and pioneering content of high impact and actuality.

This topic is robust, attracting various authors and readers; thus, further developments and results are welcome to be submitted to this second Special Issue.

This collection of papers will thus register the exciting ongoing theoretical and experimental developments in (i) the search for the leading keV WDM particle candidates and (ii) the impact of keV WDM astrophysics (including its signatures and constraints with high-redshift galaxies and clusters, cosmic recombination, 21 cm line, and implications for star formation, as well as black holes too) with or for the JWST, HST, SKA, X-ray astronomy, gravitational lensing, particle and nuclear physics, keV neutrinos, and other astronomical observations, as well as news from KATRIN, ECHo, Ptolome, and other experiments.

Astronomical evidence that cold dark matter (CDM) and its proposed tailored baryonic cures/recipes do not work at the small and galactic scales is staggering. keV WDM reproduces all observations on large as well as

galactic scales, as well as supermassive black holes.

The results by the JWST of high redshift galaxies and supermassive black holes are clearly and naturally explained by keV WDM, as, for instance, in the paper by de Vega and Sanchez and references therein, published in the first volume. And all the papers in the first volume of this Special Issue have had a great impact on the recent JWST results.

We invite our colleagues to submit their works to this Special Issue in Tribute to Héctor J. de Vega https://chalonge-devega.fr/HdeV.html.

Reviews can be submitted as well. All submitted papers must include clear purposes, results, and conclusions.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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.
