An accurate and precise Kepler Stellar Properties Catalog is essential for the interpretation of the Kepler exoplanet survey results. Previous Kepler Stellar Properties Catalogs have focused on reporting the best-available parameters for each star, but this has required combining data from a variety of heterogeneous sources. We present the Gaia-Ke…

Kraken reveals itself - the merger history of the Milky Way reconstructed with the E-MOSAICS simulations
DOI: 10.1093/mnras/staa2452 Bibcode: 2020MNRAS.498.2472K

Kruijssen, J. M. Diederik; Chevance, Mélanie; Bonaca, Ana +6 more

Globular clusters (GCs) formed when the Milky Way experienced a phase of rapid assembly. We use the wealth of information contained in the Galactic GC population to quantify the properties of the satellite galaxies from which the Milky Way assembled. To achieve this, we train an artificial neural network on the E-MOSAICS cosmological simulations o…

The Zwicky Transient Facility Catalog of Periodic Variable Stars
DOI: 10.3847/1538-4365/ab9cae Bibcode: 2020ApJS..249...18C

Tian, Hao; Yang, Ming; Wang, Shu +3 more

The number of known periodic variables has grown rapidly in recent years. Thanks to its large field of view and faint limiting magnitude, the Zwicky Transient Facility (ZTF) offers a unique opportunity to detect variable stars in the northern sky. Here, we exploit ZTF Data Release 2 (DR2) to search for and classify variables down to r ∼ 20.6 mag. …

A new set of atmosphere and evolution models for cool T-Y brown dwarfs and giant exoplanets
DOI: 10.1051/0004-6361/201937381 Bibcode: 2020A&A...637A..38P

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
DOI: 10.1051/0004-6361/202037649 Bibcode: 2020A&A...643A...2B

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…

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
DOI: 10.1093/mnras/stz3001 Bibcode: 2020MNRAS.491..740Y

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
DOI: 10.1103/PhysRevD.101.123514 Bibcode: 2020PhRvD.101l3514L

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
DOI: 10.3847/1538-4357/ab93cf Bibcode: 2020ApJ...896..166R

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
DOI: 10.1093/mnras/staa302 Bibcode: 2020MNRAS.493.1614F

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…
