Gaia Early Data Release 3. Catalogue validation
Jordi, C.; Luri, X.; Cantat-Gaudin, T. +33 more
Context. The third Gaia data release is published in two stages. The early part, Gaia EDR3, gives very precise astrometric and photometric properties for nearly two billion sources together with seven million radial velocities from Gaia DR2. The full release, Gaia DR3, will add radial velocities, spectra, light curves, and astrophysical parameters…
Gaia Early Data Release 3. Structure and properties of the Magellanic Clouds
Prusti, T.; Mazeh, T.; Zucker, S. +417 more
Context. This work is part of the Gaia Data Processing and Analysis Consortium papers published with the Gaia Early Data Release 3 (EDR3). It is one of the demonstration papers aiming to highlight the improvements and quality of the newly published data by applying them to a scientific case.
Aims: We use the Gaia EDR3 data to study the struct…
An atlas of MUSE observations towards twelve massive lensing clusters
Bacon, Roland; Carton, David; Bouché, Nicolas +24 more
Context. Spectroscopic surveys of massive galaxy clusters reveal the properties of faint background galaxies thanks to the magnification provided by strong gravitational lensing.
Aims: We present a systematic analysis of integral-field-spectroscopy observations of 12 massive clusters, conducted with the Multi Unit Spectroscopic Explorer (MUSE…
A new measurement of the Hubble constant using Type Ia supernovae calibrated with surface brightness fluctuations
Izzo, Luca; Gall, Christa; Hjorth, Jens +15 more
We present a new calibration of the peak absolute magnitude of Type Ia supernovae (SNe Ia) based on the surface brightness fluctuations (SBF) method, aimed at measuring the value of the Hubble constant. We build a sample of calibrating anchors consisting of 24 SNe hosted in galaxies that have SBF distance measurements. Applying a hierarchical Baye…
The Galaxy Activity, Torus, and Outflow Survey (GATOS). I. ALMA images of dusty molecular tori in Seyfert galaxies
Rouan, D.; Rigopoulou, D.; Hunt, L. K. +32 more
We present the first results of the Galaxy Activity, Torus, and Outflow Survey (GATOS), a project aimed at understanding the properties of the dusty molecular tori and their connection to the host galaxy in nearby Seyfert galaxies. Our project expands the range of active galactic nuclei (AGN) luminosities and Eddington ratios covered by previous s…
The VANDELS ESO public spectroscopic survey. Final data release of 2087 spectra and spectroscopic measurements
Maccagni, D.; Cimatti, A.; Elbaz, D. +94 more
VANDELS is an ESO Public Spectroscopic Survey designed to build a sample of high-signal-to-noise ratio, medium-resolution spectra of galaxies at redshifts between 1 and 6.5. Here we present the final Public Data Release of the VANDELS Survey, comprising 2087 redshift measurements. We provide a detailed description of sample selection, observations…
Three Lyman-α-emitting filaments converging to a massive galaxy group at z = 2.91: discussing the case for cold gas infall
Finoguenov, A.; Daddi, E.; Elbaz, D. +21 more
We have discovered a 300 kpc-wide giant Lyman-α (Lyα) nebula centered on the massive galaxy group RO-1001 at z = 2.91 in the Cosmic Evolution Survey field. Keck Cosmic Web Imager observations reveal three cold gas filaments converging into the center of the potential well of its ∼4 × 1013 M⊙ dark matter halo, hosting 1200 M
The MUSE Extremely Deep Field: The cosmic web in emission at high redshift
Feltre, A.; Roth, M.; Steinmetz, M. +29 more
We report the discovery of diffuse extended Lyα emission from redshift 3.1 to 4.5, tracing cosmic web filaments on scales of 2.5−4 cMpc. These structures have been observed in overdensities of Lyα emitters in the MUSE Extremely Deep Field, a 140 h deep MUSE observation located in the Hubble Ultra-Deep Field. Among the 22 overdense regions identifi…
Kiloparsec view of a typical star-forming galaxy when the Universe was ∼1 Gyr old. I. Properties of outflow, halo, and interstellar medium
Lutz, D.; Genzel, R.; Förster Schreiber, N. +9 more
We present new Atacama Large Millimeter/Submillimeter Array observations of the [C II] 158 µm transition and the dust continuum in HZ4, a typical star-forming galaxy when the Universe was only ∼1 Gyr old (z ≈ 5.5). Our high ≈0.3″ spatial resolution allows us to study the relationships between [C II] line emission, star formation rate, and fa…
Fast rotating and low-turbulence discs at z ≃ 4.5: Dynamical evidence of their evolution into local early-type galaxies
Magnelli, B.; Gómez-Guijarro, C.; Jiménez-Andrade, E. F. +3 more
Massive starburst galaxies in the early Universe are estimated to have depletion times of ∼100 Myr and thus be able to convert their gas very quickly into stars, possibly leading to a rapid quenching of their star formation. For these reasons, they are considered progenitors of massive early-type galaxies (ETGs). In this paper, we study two high-z…
