The large scale velocity field from the Cosmicflows-4 data
Yehuda Hoffman, Aurélien Valade, Noam I. Libeskind +5
The reconstruction of the large scale velocity field from the grouped Cosmicflows-4 (CF4) database is presented. The lognormal bias of the inferred distances and velocities data is…
Simulating the LOcal Web (SLOW) -- III: Synchrotron emission from the local cosmic web
Ludwig M. Böss, Klaus Dolag, Ulrich P. Steinwandel +4
Aims: Detecting diffuse synchrotron emission from the cosmic web is still a challenge for current radio telescopes. We aim to make predictions about the detectability of cosmic web…
Mass bias in clusters of galaxies: Projection effects on the case study of Virgo replica
Théo Lebeau, Jenny G. Sorce, Nabila Aghanim +2
When measuring the observed pressure, density or temperature profiles of the intracluster gas, and hence the mass of clusters of galaxies, projection effects or departures from the…
Statistically bias-minimized peculiar velocity catalogs from Gibbs point processes and Bayesian inference
Jenny G. Sorce, Radu S. Stoica, Elmo Tempel
Galaxy peculiar velocities are excellent cosmological probes provided that biases inherent to their measurements are contained before any study. This paper proposes a new algorithm…
Kinematics of the Local Group gas and galaxies in the Hestia simulations
Luis Biaus, Sebastián E. Nuza, Cecilia Scannapieco
The Local Group (LG) consists of two giant spiral galaxies, the Milky Way (MW) and Andromeda (M31), and several smaller galaxies. The MW and M31 are approaching each other at a rad…
The cosmic web around the Coma cluster from constrained cosmological simulations: I. Filaments connected to Coma at
Nicola Malavasi, Jenny G. Sorce, Klaus Dolag +1
Galaxy clusters in the Universe occupy the important position of nodes of the cosmic web. They are connected among them by filaments, elongated structures composed of dark matter,…
Simulating the LOcal Web (SLOW): I. Anomalies in the local density field
Klaus Dolag, Jenny G. Sorce, Sergey Pilipenko +5
Context: Several observations of the local Universe (LU) point towards the existence of very prominent structures. The presence of massive galaxy clusters and local super clusters…
Cosmic Variance and the Inhomogeneous UV Luminosity Function of Galaxies During Reionization
Taha Dawoodbhoy, Paul R. Shapiro, Pierre Ocvirk +8
When the first galaxies formed and starlight escaped into the intergalactic medium to reionize it, galaxy formation and reionization were both highly inhomogeneous in time and spac…
Distortions of the Hubble diagram: Line-of-sight signatures of local galaxy clusters
Jenny G. Sorce, Roya Mohayaee, Nabila Aghanim +2
The Universe expansion rate is modulated around local inhomogeneities due to their gravitational potential. Velocity waves are then observed around galaxy clusters in the Hubble di…
