Four New Publications at the Open Journal of Astrophysics
It’s Satuday morning once again so here’s another quick update of activity at the Open Journal of Astrophysics. Since the last update a week ago we have published four papers, which takes the count in Volume 7 (2024) up to 114 and the total published altogether by OJAp up to 229. If we publish just one more paper between now and the end of the year, we will have published as many papers in 2024 as we have in all previous years.
Anyway, in chronological order of publication, the four papers published this week, with their overlays, are as follows. You can click on the images of the overlays to make them larger should you wish to do so.
First one up is “Star formation beyond galaxies: widespread in-situ formation of intra-cluster stars” by Niusha Ahvazi & Laura V. Sales (UC Riverside, USA), Julio F. Navarro (U. Victoria, Canada), Andrew Benson (Carnegie Obs. USA), Alessandro Boselli (Aix Marseille U., France) and Richard D’Souza (Vatican Obs.). The paper, which is in the folder marked Astrophysics of Galaxies, The paper presents a simulation-based analysis of a diffuse star forming component in galaxy clusters extending for hundreds of kiloparsecs and tracing the distribution of neutral gas in the cluster host halo.
Here is a screen grab of the overlay, which includes the abstract:
You can find the officially accepted version of the paper on the arXiv here.
The second paper to announce, published on 10th December 2024 in the folder Cosmology and NonGalactic Astrophysics, is “Cosmological Constraints from Combining Photometric Galaxy Surveys and Gravitational Wave Observatories” by E.L. Gagnon, D. Anbajagane, J. Prat, C. Chang, and J. Frieman (all of U. Chicago, USA). This article quantifies the expected cosmological information gain from combining the forecast LSST 3x2pt analysis with the large-scale auto-correlation of GW sources from proposed next-generation GW experiments.
You can see the overlay here:
The accepted version of this paper can be found on the arXiv here.
The third paper, also published on 10th December 2024, but in the folder marked Earth and Planetary Astrophysics, has the title “A potential exomoon from the predicted planet obliquity of β Pictoris b” and is written by Michael Poon, Hanno Rein, and Dang Pham all of the University of Toronto, Canada. It presents discussion, based on the β Pictoris system, of the idea that the presence of exomoons can excite misalignment between the spin and orbit axis (obliquity) in exoplanet systems
Here is the overlay
The final version accepted on arXiv is here.
Last of this quartet, published on 11th December 2024, and in the folder Cosmology and NonGalactic Astrophysics is “Map-level baryonification: Efficient modelling of higher-order correlations in the weak lensing and thermal Sunyaev-Zeldovich fields” and is by Dhayaa Anbajagane & Shivam Pandey (U. Chicago) and Chihway Chang (Columbia U.), all based in the USA.
The paper proposes an extension of the semi-analytic formalism to weak lensing and thermal Sunyaev-Zeldovich (tSZ) fields directly on the full-sky, with an emphasis on higher-order correlations. The overlay is here:
You can find the official accepted version on the arXiv here.
That’s all for this week. I’ll do another update next Saturday, and that will probably be the last one of the year. If we publish just one more paper between now and 31st December, we will have published as many papers in 2024 as we have in all previous years put together!

Large #Exomoons unlikely around Kepler-1625 b and Kepler-1708 b: https://arxiv.org/abs/2312.03786 -> "Here we reanalyse the Hubble and Kepler data used to identify the two exomoon candidates employing nested sampling and Bayesian inference techniques coupled with a fully automated photodynamical transit model. [...] Our injection-retrieval experiments of simulated transits in the original Kepler data reveal false positive rates of 10.9% and 1.6% for Kepler-1625 b and Kepler-1708 b, respectively."

The big planet-forming ring around the #star PDS 70 is clearly imaged.
But it is not the #planet on the right, just inside the ring, that’s being talked about the most.
Although the planet PDS 70c is a newly formed and, interestingly, similar in size and mass to #Jupiter, it's the fuzzy patch around the planet PDS 70c that's causing the commotion.
That fuzzy patch is thought to be a dusty disk that is now forming into #moons.

In case anyone is wondering why some of us #exoplanet #scientists are interested in today's launch of #ESAEuclid, here's a link to a recent #WhitePaper that the #EuclidMission Exoplanet Science Working Group posted a few days ago. In it we explain how Euclid could help the #nasa #RomanMission to test planet formation theories, hunt and confirm the existence and nature of free floating planets, and possibly make the first discovery of #exomoons - moons around #exoplanets

Presence of liquid water during the evolution of #exomoons orbiting ejected free-floating planets: https://arxiv.org/abs/2302.04946 - "Earth-mass moons with CO2-dominated atmospheres could retain liquid water on their surfaces for long timescales, depending on the mass of the atmospheric envelope and the surface pressure assumed" -> Life on distant moons: https://www.origins-cluster.de/en/news-events/news/detail?tx_news_pi1%5Bnews%5D=313&cHash=cd72b6d32089c3829ad148e3728d0cda

Life on distant moons🌑? Researchers from #ORIGINSExcellenceCluster, including #MPE scientist Tommaso Grassi, have determined the necessary properties that allow moons around free-floating planets to retain liquid water 💦 for a sufficiently long time and thus enable life.

Cool.
"[T]here’s intriguing evidence that a planet orbiting a nearby star may have the raw materials to build a moon, and one or more moons may be forming there right now. New (and extremely cool) observations confirm earlier ones that the planet is surrounded by a disk of dust with enough mass to make several moons the size of our own Moon."
