Planck 2018 results. VI. Cosmological parameters
Kim, J.; Miville-Deschênes, M. -A.; Boulanger, F. +179 more
We present cosmological parameter results from the final full-mission Planck measurements of the cosmic microwave background (CMB) anisotropies, combining information from the temperature and polarization maps and the lensing reconstruction. Compared to the 2015 results, improved measurements of large-scale polarization allow the reionization opti…
TDCOSMO. IV. Hierarchical time-delay cosmography - joint inference of the Hubble constant and galaxy density profiles
Treu, T.; Christensen, L.; Koopmans, L. V. E. +24 more
The H0LiCOW collaboration inferred via strong gravitational lensing time delays a Hubble constant value of H0 = 73.3-1.8+1.7 km s-1 Mpc-1, describing deflector mass density profiles by either a power-law or stars (constant mass-to-light ratio) plus standard dark matter halos. The mass-sheet tr…
A new set of atmosphere and evolution models for cool T-Y brown dwarfs and giant exoplanets
Tremblin, P.; Allard, N. F.; Baraffe, I. +6 more
We present a new set of solar metallicity atmosphere and evolutionary models for very cool brown dwarfs and self-luminous giant exoplanets, which we term ATMO 2020. Atmosphere models are generated with our state-of-the-art 1D radiative-convective equilibrium code ATMO, and are used as surface boundary conditions to calculate the interior structure…
The ALPINE-ALMA [CII] survey: Data processing, catalogs, and statistical source properties
Cimatti, A.; Pozzi, F.; Schaerer, D. +33 more
The Atacama Large Millimeter Array (ALMA) Large Program to INvestigate [CII] at Early times (ALPINE) targets the [CII] 158 µm line and the far-infrared continuum in 118 spectroscopically confirmed star-forming galaxies between z = 4.4 and z = 5.9. It represents the first large [CII] statistical sample built in this redshift range. We present…
The ALPINE-ALMA [CII] survey. Survey strategy, observations, and sample properties of 118 star-forming galaxies at 4 < z < 6
Cimatti, A.; Maiolino, R.; Pozzi, F. +43 more
The ALMA-ALPINE [CII] survey is aimed at characterizing the properties of a sample of normal star-forming galaxies (SFGs). The ALMA Large Program to INvestigate (ALPINE) features 118 galaxies observed in the [CII]-158 µm line and far infrared (FIR) continuum emission during the period of rapid mass assembly, right after the end of the HI rei…
The ALPINE-ALMA [CII] survey. The nature, luminosity function, and star formation history of dusty galaxies up to z ≃ 6
Cimatti, A.; Pozzi, F.; Rodighiero, G. +30 more
Aims: We present the detailed characterisation of a sample of 56 sources serendipitously detected in ALMA band 7 as part of the ALMA Large Program to INvestigate CII at Early Times (ALPINE). These sources, detected in COSMOS and ECDFS, have been used to derive the total infrared luminosity function (LF) and to estimate the cosmic star formati…
The stellar-to-halo mass relation over the past 12 Gyr. I. Standard ΛCDM model
Bolzonella, M.; Giocoli, C.; Marulli, F. +3 more
Aims: Understanding the link between the galaxy properties and the dark matter halos they reside in and their coevolution is a powerful tool for constraining the processes related to galaxy formation. In particular, the stellar-to-halo mass relation (SHMR) and its evolution throughout the history of the Universe provides insights on galaxy fo…
Observations of edge-on protoplanetary disks with ALMA. I. Results from continuum data
Pinte, C.; Ménard, F.; Duchêne, G. +15 more
Aims: We aim to study vertical settling and radial drift of dust in protoplanetary disks from a different perspective: an edge-on view. An estimation of the amplitude of settling and drift is highly relevant to understanding planet formation.
Methods: We analyze a sample of 12 HST-selected edge-on protoplanetary disks (i.e., seen with hi…
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS). IV. A spectral inventory of atoms and molecules in the high-resolution transmission spectrum of WASP-121 b
Heng, K.; Ségransan, D.; Ehrenreich, D. +22 more
Context. WASP-121 b is a hot Jupiter that was recently found to possess rich emission (day side) and transmission (limb) spectra, suggestive of the presence of a multitude of chemical species in the atmosphere.
Aims: We survey the transmission spectrum of WASP-121 b for line-absorption by metals and molecules at high spectral resolution and e…
The origin of the escape of Lyman α and ionizing photons in Lyman continuum emitters
Chisholm, J.; Schaerer, D.; Verhamme, A. +2 more
Context. Identifying the physical mechanisms driving the escape of Lyman continuum (LyC) photons is crucial for the search of Lyman continuum emitter (LCE) candidates.
Aims: To understand the physical properties involved in the leakage of LyC photons, we investigate the connection between the H I covering fraction, H I velocity width, the Lym…
