Analytical covariances for catalogue-based pseudo-s
Kevin Wolz, Elyas Farah, Robert Reischke +2
The paper presents a method to analytically compute the Gaussian (disconnected) covariance of angular power spectra estimated directly from discrete source catalogues, accounting f…
Probing the Baryon Distribution with Fast Radio Bursts
Manisha Caleb, Jéferson A. S. Fortunato, Steffen Hagstotz +12
The paper investigates how fast radio bursts observed with the Square Kilometre Array can be used to map the distribution of baryonic matter from cosmological to galactic scales, b…
KiDS-Legacy: The consistency test of the large-scale structure with Bernardeau-Nishimichi-Taruya transform
Shiming Gu, Ziang Yan, Ludovic van Waerbeke +10
We perform the first -cut cosmic shear analysis of the KiDS-Legacy survey. This method uses the Bernardeau-Nishimichi-Taruya (BNT) transform to construct weak-lensing kernels th…
Fast Radio Bursts as Cosmological Probes
Manisha Caleb, Jéferson A. S. Fortunato, Steffen Hagstotz +14
Fast radio bursts (FRBs) are brief, coherent radio pulses of extragalactic origin. They typically last from microseconds to milliseconds and have energies large enough to be visibl…
A first measurement of baryonic feedback with Fast Radio Bursts
Robert Reischke, Steffen Hagstotz
Baryonic feedback fundamentally alters the total matter distribution on small to intermediate cosmological scales, posing a significant challenge for contemporary cosmological anal…
The Astrophysics of Fast Radio Bursts
Alice P. Curtin, Marcin GawroÅski, Jason Hessels +11
Fast radio bursts (FRBs) provide a glimpse of high-energy astrophysical phenomena in other galaxies. They point the way to extreme conditions that are currently undetectable by any…
