The variance of the CMB temperature gradient: a dependence on the spatial orientation and anisotropy of a multiply connected Universe
Ralf Aurich, Martin J France, Frank Steiner
In the present work we develop a model--independent method to reveal the underlying patterns of anisotropy and geometry in CMB temperature maps. This method, based on the rho-stati…
The GECKOS survey: Assembly history of the lenticular galaxy NGC 3957
Yuchen Ding, Marie Martig, Ling Zhu +24
We analyse the assembly history of the edge-on lenticular galaxy NGC 3957 using deep integral-field spectroscopic MUSE data from the GECKOS survey. By applying a dust-corrected Mul…
Predisposition of galaxy clusters to producing exotic hyperbolic umbilic lensing configurations
Quentin Basto, Johan Richard, David J. Lagattuta +2
Strong gravitational lensing is a powerful tool for investigating the universe's large-scale structure and understanding the properties of dark matter and dark energy. The magnific…
Destructuring the disk of AB Aurigae: Dynamics and accretion
Anthony Boccaletti, Emmanuel Di Folco, Anne Dutrey +23
In this paper, we present near-IR polarized images of the AB Aur disk at three epochs spanning 3.85 years with SPHERE/IRDIS, as well as Halpha images obtained with SPHERE/ZIMPOL at…
The slope of the power spectrum of the density field in isothermal supersonic compressible turbulence
Pierre Dumond, Jérémy Fensch, Gilles Chabrier +1
The power spectrum (PS) of the density field in supersonic turbulence is a fundamental quantity that characterizes the statistical properties of the structures formed in compressib…
Backreaction and the Role of Spatial Curvature in the Cosmic Neighborhood
Marco Galoppo, Thomas Buchert, Pierre Mourier
We present the first direct computation of spatially averaged dynamical quantities in the local Universe, employing the Cosmicflows-4++ reconstruction and a covariant scalar averag…
