My paper with Jun-Qian Jiang, William Giarè, Stefano Gariazzo, Maria Giovanna Dainotti, Eleonora Di Valentino, Olga Mena, Davide Pedrotti, and Simony Santos da Costa, where we investigate the status of (positive) neutrino mass cosmology after the latest DESI measurements (see this earlier news item), has been accepted for publication in JCAP! The paper has undergone has a substantial revision, which resulted in the addition of several appendices clarifying various technical aspects of the analysis (e.g. cosmology-internal tension, impact of PR4 likelihoods, and H0 versus MB prior among others), as well as an additional useful plot, and useful discussions on the neutrino mass ordering: however, the main results are unaltered, and are now more robust.

Scale-invariant inflation paper accepted in JCAP!
My paper with with with Chiara Cecchini, Mariaveronica De Angelis, William Giarè, and Max Rinaldi, where we tested a theoretically very well-motivated classically scale-invariant inflationary model against current cosmological data (see this earlier news item), has been accepted for publication in JCAP! There were a few minor changes in order to better clarify a few aspects of our analysis, but the results are completely unchanged with respect to the earlier version. You can read the preprint version of the paper on arXiv: 2403.04316.

State of the dark energy equation of state paper accepted in JCAP!
My paper with with Luis Escamilla, William Giarè, Eleonora Di Valentino, and Rafael Nunes, where we present state-of-the-art constraints on the dark energy equation of state from a number of cosmological probes (see this earlier news item), has been accepted for publication in JCAP! There were a few changes, mostly making a few parts of the discussion clearer, but the results are otherwise completely unchanged compared to the previous version we posted this summer. You can read the preprint version of the paper on arXiv: 2307.14802.
IOP Trusted Reviewer Status
I’m extremely glad to have been awarded the status of IOP Trusted Reviewer! This is a certification from the Institute of Physics (IOP) which recognizes the best reviewers for IOP journals, in recognition of an exceptionally high level of peer review competency, as rated by the editors (more specifically, it recognizes “a high level of peer review competence, with the ability to critique scientific literature to an excellent standard”). In practice, it recognizes reviewers who consistently submit good reviews. The IOP journals I regularly review for (which are also journals where I regularly publish my papers) are JCAP and CQG. I believe in the value of peer review and put significant efforts into ensuring my reviews are always detailed and helpful for the authors, so I am glad this has been officially recognized!
Laniakea paper published in JCAP!
My paper on Laniakea with Leo Giani, Cullan Howlett, Khaled Said, and Tam Davis, which I previously reported on in an earlier news item, has now officially been published in JCAP! The full bibliographic coordinates for the paper are JCAP 2401 (2024) 071. Here is the link to the paper (which is published Open Access).
Laniakea paper accepted in JCAP!
My paper with Leo Giani, Cullan Howlett, Khaled Said, and Tam Davis, where we show how the Hubble tension is worsened when properly accounting for local effects of Laniakea (see this earlier news item), has been accepted for publication in JCAP - excellent Christmas present! There were a few minor changes compared to the previous version, and I especially want to highlight the first sentence from the referee report, which in my opinion really sums up the impact of the paper and of Leo’s exceptional work: “I found this paper to be a significant contribution to the characterization of our local spacetime“ (thank you so much referee, whoever you are!). You can read the preprint version of the paper on arXiv: 2311.00215.
Negative cosmological constant and JWST paper published in JCAP!
My paper with Shahnawaz Adil, Upala Mukhopadhyay, and Anjan Sen, studying a dark energy model featuring a negative cosmological constant in light of the JWST observations, which I previously reported on in an earlier news item, has now officially been published in JCAP! The full bibliographic coordinates for the paper are JCAP 2310 (2023) 072. Here is the link to the paper (which is published Open Access).
Negative cosmological constant and JWST paper accepted in JCAP!
My paper with Shahnawaz Adil, Upala Mukhopadhyay, and Anjan Sen, where we show how a dark energy model featuring a negative cosmological constant with an evolving component on top can potentially explain the puzzling JWST observations (see this earlier news item), has been accepted for publication in JCAP! The revision requested was pretty minor, but a notable (and in my opinion rather important) addition is the new Fig. 1 I produced, where we show the effective equation of state of this dark energy model. In some cases it goes through a singularity, which indicates the point where the total energy density of the dark energy switches sign. The singularity is nothing to worry about, as we argued. You can read the preprint version of the paper on arXiv: 2307.12763.
Asteroid and fifth forces paper published in JCAP!
My paper with Yu-Dai Tsai, Youjia Wu, and Luca Visinelli on the use of asteroids as a probe of fifth forces, which I previously reported on in an earlier news item, has now officially been published in JCAP! The full bibliographic coordinates for the paper are JCAP 2304 (2023) 031. Here is the link to the paper.
Asteroid precession and fifth forces paper accepted in JCAP!
My paper with Yu-Dai Tsai, Youjia Wu, and Luca Visinelli, where we use asteroids as a probe of fifth forces, including those mediated by new ultralight particles which could be the dark matter, has been accepted for publication in JCAP! We find that we can potentially set some of the leading fifth force constraints in a certain range of mediator mass. This is another paper which has gone through a really long journey, as it was conceived during a brainstorm Zoom call in October 2020. We are now developing a number of follow-up ideas with asteroid experts, so stay tuned for more! You can find the preprint version of the paper on arXiv: 2107.04038.
