I had the pleasure to be interviewed by Alexandre Morales for France Culture, to talk about the discovery of Quipu, one of the largest known structure of the Universe. It will air tomorrow morning at 6:52.
Here is the press release by the authors of the discovery at MPI Garching https://www.mpg.de/24197951/largest-superstructure-in-the-nearby-universe

Time for another roundup of business at the Open Journal of Astrophysics. This time I have three papers to announce, which brings the total we have published so far this year (Vol. 7) to 45 and the total published by OJAp to 160. We’re still on track to publish around 100 papers this year or more, compared to last year’s 50.
First one up, published on 3rd June 2024, is “Log-Normal Waiting Time Widths Characterize Dynamics” by Jonathan Katz of Washington University (St Louis, Missouri, USA). This paper presents a discussion of the connection between waiting time distributions and dynamics for aperiodic astrophysical systems, with emphasis on log-normal distributions. This paper is in the folder marked High-Energy Astrophysical Phenomena.
Here is a screen grab of the overlay, which includes the abstract:
You can read the paper directly on arXiv here.
The second paper to present is “An Empirical Model For Intrinsic Alignments: Insights From Cosmological Simulations” by Nicholas Van Alfen (Northeastern University, Boston, USA), Duncan Campbell (Carnegie Mellon University, Pittsburgh, USA), Jonathan Blazek (Northeastern University), C. Danielle Leonard (Newcastle University, UK), Francois Lanusse (Université Paris-Saclay, France), Andrew Hearin (Argonne National Laboratory, USA), Rachel Mandelbaum (Carnegie Mellon University) and The LSST Dark Energy Science Collaboration. This paper presents an extension of the halo model (specifically the Halo Occupation Distribution, HOD) to include intrinsic alignment effects for the study of weak gravitational lensing. This paper is in the folder marked Cosmology and Nongalactic Astrophysics. It was published on Tuesday June 4th 2024.
The overlay looks like this:
You can read this paper directly on the arXiv here.
Last, but by no means least, comes “Towards Cosmography of the Local Universe” which proposes the multipoles of the distance-redshift relation as new cosmological observables that have a direct physical interpretation in terms of kinematical quantities of the underlying matter flow. This was also published on 4th June. The authors are Julian Adamek (IfA Zurich, Switzerland), Chris Clarkson (Queen Mary, London, UK), Ruth Durrer (Geneva, Switzerland), Asta Heinesen (U. Lyon, France & NBI Copenhagen, Denmark), Martin Kunz (Geneva), and Hayley J. Macpherson (Chicago, USA).
Here is a screengrab of the overlay:
To read the accepted version of this on the arXiv please go here. This paper is also in the folder marked Cosmology and Nongalactic Astrophysics. That’s it for this week. I aim to post another update next weekend.https://telescoper.blog/2024/06/08/three-new-publications-at-the-open-journal-of-astrophysics-9/

I love it that Star Wars goes extragalactic in Ahsoka.
Brilliant Cosmography scene wherein a cosmographer witch finds the path leading to the galaxy where Grand Admiral Thrawn is exiled!
