Four New Publications at the Open Journal of Astrophysics

Story


It is time yet again for an update of recent activity at the Open Journal of Astrophysics.

This week we have published four papers, which I now present to you. These four take the count in Volume 7 (2024) up to 36 and the total published by OJAp up to 151. I speculated last week that we would probably pass the 150 mark this week, and so we did. We’re still on target to publish around 100 papers this year.

In chronological order, 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 “Ephemeris Matching Reveals False Positive Validated and Candidate Planets from the K2 Mission” by Drake A. Lehmann (U. Wisconsin-Madison, USA) and Andrew Vanderburg (MIT, USA). It presents a description and application of a technique for identifying false positives among candidate exoplanets. The paper was published on 7th May 2024, is in the folder marked Earth and Planetary Astrophysics, and can be found here.

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 is “Accuracy requirements on intrinsic alignments for Stage-IV cosmic shear” which is by by Anya Paopiamsap, Natalia Porqueres & David Alonso (Oxford, UK) and Joachim Harnois-Deraps & C. Danielle Leonard (Newcastle, UK). This paper sets about quantifying the Quantifying the permissible level of disagreement between the true intrinsic galaxy alignments and the theoretical models thereof that can be allowed for future Stage-IV cosmic shear surveys. This one is in the folder marked Cosmology and Nongalactic Astrophysics. The paper was published on May 9th 2024 and you can see the overlay here:

 

The accepted version of this paper can be found on the arXiv here.

The next paper, is in the folder Instrumentation and Methods for Astrophysics and is entitled “Optimal Summary Statistics for X-ray Polarization”. The authors are Jeremy Heyl (Uni. British Columbia, Canada), Denis González-Caniulef (Uni. Toulouse, France) and Ilaria Caiazzo (Caltech, USA). This presents new statistical estimators for use in studies of X-ray polarization, with an analytic discussion of their efficiency. It can be found here and the accepted version can be read on arXiv here. Here is the overlay:

The last paper of this batch is called  “B-modes from galaxy cluster alignments in future surveys” and is by Christos Georgiou, Thomas Bakx, Juliard van Donkersgoed and Nora Elisa Chisari, all from Utrecht University in The Netherlands. It presents a discussion of the possible detection of cosmic shear B-modes produced by intrinsic alignments in future galaxy surveys.

Here is the overlay:

You can find the full text for this one on the arXiv here. The primary classification for this one is Cosmology and Nongalactic Astrophysics.

And that ends this week’s update. More next week!
