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 Solar Orbiter Solar Wind Analyser (SWA) suite
André, N.; Fedorov, A.; Livi, S. +126 more
The Solar Orbiter mission seeks to make connections between the physical processes occurring at the Sun or in the solar corona and the nature of the solar wind created by those processes which is subsequently observed at the spacecraft. The mission also targets physical processes occurring in the solar wind itself during its journey from its sourc…
X-CIGALE: Fitting AGN/galaxy SEDs from X-ray to infrared
Ciesla, L.; Papovich, C.; Brandt, W. N. +6 more
Code Investigating GALaxy Emission (CIGALE) is a powerful multiwavelength spectral energy distribution (SED) fitting code for extragalactic studies. However, the current version of CIGALE is not able to fit X-ray data, which often provide unique insights into active galactic nucleus (AGN) intrinsic power. We develop a new X-ray module for CIGALE, …
I N T E G R A L constraints on primordial black holes and particle dark matter
Slatyer, Tracy R.; Muñoz, Julian B.; Laha, Ranjan
The International Gamma-Ray Astrophysics Laboratory (I N T E G R A L ) satellite has yielded unprecedented measurements of the soft gamma-ray spectrum of our Galaxy. Here we use those measurements to set constraints on dark matter (DM) that decays or annihilates into photons with energies E ≈0.02 - 2 MeV . First, we revisit the constraints on part…
Gamma-Ray Burst Afterglows in the Multimessenger Era: Numerical Models and Closure Relations
Piro, Luigi; Ryan, Geoffrey; Troja, Eleonora +1 more
Gamma-ray bursts (GRBs) associated with gravitational wave events are, and will likely continue to be, viewed at a larger inclination than GRBs without gravitational wave detections. As demonstrated by the afterglow of GW 170817A, this requires an extension of the common GRB afterglow models, which typically assume emission from an on-axis top-hat…
A cosmic UV/X-ray background model update
Faucher-Giguère, Claude-André
We present an updated model of the cosmic ionizing background from the UV to the X-rays. Relative to our previous model, the new model provides a better match to a large number of up-to-date empirical constraints, including: (1) new galaxy and AGN luminosity functions; (2) stellar spectra including binary stars; (3) obscured and unobscured AGN; (4…
STRIDES: a 3.9 per cent measurement of the Hubble constant from the strong lens system DES J0408-5354
Bechtol, K.; Smith, M.; Finley, D. A. +88 more
We present a blind time-delay cosmographic analysis for the lens system DES J0408-5354. This system is extraordinary for the presence of two sets of multiple images at different redshifts, which provide the opportunity to obtain more information at the cost of increased modelling complexity with respect to previously analysed systems. We perform d…
Host Galaxy Properties and Offset Distributions of Fast Radio Bursts: Implications for Their Progenitors
Kilpatrick, Charles D.; Simha, Sunil; Mannings, Alexandra +15 more
We present observations and detailed characterizations of five new host galaxies of fast radio bursts (FRBs) discovered with the Australian Square Kilometre Array Pathfinder (ASKAP) and localized to ≲1″. Combining these galaxies with FRB hosts from the literature, we introduce criteria based on the probability of chance coincidence to define a sub…
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…
Planck 2018 results. XII. Galactic astrophysics using polarized dust emission
Kim, J.; Miville-Deschênes, M. -A.; Boulanger, F. +160 more
Observations of the submillimetre emission from Galactic dust, in both total intensity I and polarization, have received tremendous interest thanks to the Planck full-sky maps. In this paper we make use of such full-sky maps of dust polarized emission produced from the third public release of Planck data. As the basis for expanding on astrophysica…
