CAVITY, Calar Alto Void Integral-field Treasury surveY and project extension Open
We have learnt in the last decades that the majority of galaxies belong to high density regions interconnected in a sponge-like fashion. This large-scale structure is characterised by clusters, filaments, walls, where most galaxies concent…
Sociology and hierarchy of voids: A study of seven nearby CAVITY galaxy voids and their dynamical CosmicFlows-3 environment Open
Context. The present study addresses a key question related to our understanding of the relation between void galaxies and their environment: the relationship between luminous and dark matter in and around voids. Aims. To explore the exten…

Cosmicflows-4 Open
With Cosmicflows- 4, distances are compiled for 55,877 galaxies gathered into 38,065 groups. Eight methodologies are employed, with the largest numbers coming from the correlations between the photometric and kinematic properties of spiral…
Gravity in the local Universe: Density and velocity fields using CosmicFlows-4 Open
This article publicly releases 3D reconstructions of the local Universe gravitational field below z = 0.8 that were computed using the CosmicFlows-4 (CF4) catalog of 56 000 galaxy distances and its subsample of 1008 supernovae distances. T…

WALLABY pre-pilot and pilot survey: The Tully Fisher relation in Eridanus, Hydra, Norma, and NGC4636 fields Open
The WALLABY pilot survey has been conducted using the Australian SKA Pathfinder (ASKAP). The integrated 21-cm H i line spectra are formed in a very different manner compared to usual single-dish spectra Tully–Fisher measurements. It is thu…

<i>Euclid</i>: Cosmological forecasts from the void size function Open
The Euclid mission – with its spectroscopic galaxy survey covering a sky area over 15 000 deg 2 in the redshift range 0.9 < z < 1.8 – will provide a sample of tens of thousands of cosmic voids. This paper thoroughly explores for the first …

Structure of $^{83}$As, $^{85}$As and $^{87}$As: from semi-magicity to\n $\\gamma$-softness Open
The structure of $^{83}$As, $^{85}$As and $^{87}$As have been studied in\nfusion-fission reaction $^{238}$U+$^9$Be. Fission fragments were identified in\nmass and atomic number using the VAMOS++ spectrometer and the coincident\n$\\gamma$-r…
Cosmicflows-4: the baryonic Tully–Fisher relation providing ∼10 000 distances Open
The interstellar gas in spiral galaxies can constitute a significant fraction of the baryon mass and it has been demonstrated that the sum of stellar and gas components correlates well with the kinematic signature of the total mass content…
Toward Cosmicflows-4: The HI data catalog Open
Aims. In this study, we present an update of a compilation of line width measurements of neutral atomic hydrogen (H I ) galaxy spectra at 21 cm wavelength. Our All Digital HI (ADHI) catalog consists of the previous release augmented with o…
Segmenting the Universe into dynamically coherent basins Open
This paper explores in depth a watershed concept to partition the Universe, introduced in a previous Letter and applied to the Cosmicflows-3 observational data set. We present a series of tests conducted with cosmological dark matter simul…

Peculiar velocity cosmology with type Ia supernovae Open
Type Ia Supernovae have yet again the opportunity to revolutionize the field of cosmology as the new generation of surveys are acquiring thousands of nearby SNeIa opening a new era in cosmology: the direct measurement of the growth of stru…
Partitioning the Universe into gravitational basins using the cosmic velocity field Open
This letter presents a new approach using the cosmic peculiar velocity field to characterize the morphology and size of large-scale structures in the local Universe. The algorithm developed uses the three-dimensional peculiar velocity fiel…

Validation of a new “3D calorimetry” of hot nuclei with the HIPSE event generator Open
In nuclear thermodynamics, the determination of the excitation energy of hot\nnuclei is a fundamental experimental problem. Instrumental physicists have been\ntrying to solve this problem for several years by building the most exhaustive\n…

New “3D calorimetry” of hot nuclei Open
In the domain of Fermi energy, it is extremely complex to isolate experimentally fragments and particles issued from the cooling of a hot nucleus produced during a heavy ion collision. This paper presents a new method to characterize more …

Probing clustering in excited alpha-conjugate buclei Open
The fragmentation of quasi-projectiles from the nuclear reaction $^{40}$Ca+$^{12}$C at 25 MeV per nucleon bombarding energy was used to produce $α$-emission sources. From a careful selection of these sources provided by a complete detectio…
