A possible tension between galaxy rotational velocity and observed physical properties
Lior Shamir, Darius McAdam
The discrepancy between the mass of galaxies and their rotational velocity is one of the most puzzling scientific phenomena. Despite over a century of research, this phenomenon is…
Analysis of spin directions of galaxies in the DESI Legacy Survey
Lior Shamir
The DESI Legacy Survey is a digital sky survey with a large footprint compared to other Earth-based surveys, covering both the Northern and Southern hemispheres. This paper shows t…
Asymmetry in galaxy spin directions -- analysis of data from DES and comparison to four other sky surveys
Lior Shamir
The paper shows an analysis of the large-scale distribution of galaxy spin directions of 739,286 galaxies imaged by DES. The distribution of the spin directions of the galaxies exh…
Using 3D and 2D analysis for analyzing large-scale asymmetry in galaxy spin directions
Lior Shamir
The nature of galaxy spin is still not fully known. Iye et al (2021) applied a 3D analysis to a dataset of bright SDSS galaxies that was used in the past for photometric analysis.…
Is the Observable Universe Consistent with the Cosmological Principle?
Pavan Kumar Aluri, Paolo Cea, Pravabati Chingangbam +20
The Cosmological Principle (CP) -- the notion that the Universe is spatially isotropic and homogeneous on large scales -- underlies a century of progress in cosmology. It is conven…
Analysis of spiral galaxies from four telescopes shows large-scale patterns of asymmetry in galaxy spin directions
Lior Shamir
The ability to collect unprecedented amounts of astronomical data has enabled the studying scientific questions that were impractical to study in the pre-information era. This stud…
