Debiasing Local Cluster Infall Reveals : Application to the Virgo Cluster
Bastien Carreres, David Benisty, Jenny Wagner +3
Galaxy recession velocities are commonly used to measure the Hubble constant, , with peculiar velocities treated as random noise. Around massive clusters, however, these motio…
How much dark matter really matters?
Jenny Wagner
Strong gravitational lensing is a key probe to trace dark matter. It assumes that mass curves spacetime so that light from a background source is deflected on its way to the observ…
Hamilton's Object Revisited: A challenging source redshift of a strong lensing configuration
Jenny Wagner, Emilio E. Falco
Low-resolution spectrographs used to have difficulties in determining redshifts of galaxies at and . Spectral emission and absorption lines of magnesium and…
The Binary Ballet: Mapping Local Expansion Around M81 & M82
Jenny Wagner, David Benisty, Igor D. Karachentsev
This study of the M81 complex and its Hubble flow delivers new and improved Tip of the Red Giant Branch (TRGB)-based distances for nine member galaxies, yielding a total of 58 gala…
Unveiling the Coma Cluster Structure: From the Core to the Hubble Flow
David Benisty, Jenny Wagner, Sandeep Haridasu +1
The Coma cluster, embedded in a cosmic filament, is a complex and dynamically active structure in the local Universe. Applying a density-based member selection dbscan to data from…
Galaxy infall models for arbitrary velocity directions
Jenny Wagner, David Benisty
For most galaxies in the cosmos, our knowledge of their motion is limited to line-of-sight velocities from redshift observations. To determine the radial velocity between two galax…
Observables of super-extremal black holes: challenging Cosmic Censorship to comprehend the Cosmological Constant
Jenny Wagner
Einstein's Field Equations have proven applicable across many scales, from black holes to cosmology. Even the mysterious Cosmological Constant found a physical interpretation in th…
Dark Energy as a Critical Period in Binary Motion: Bounds from Multi-scale Binaries
David Benisty, Jenny Wagner, Denitsa Staicova
The two-body problem under the influence of both dark energy and post-Newtonian modifications is studied. In this unified framework, we demonstrate that dark energy plays the role…
