Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS / Fermi-LAT Collaboration
Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low astrophysical background. [...]

Physics potential of the International Axion Observatory (IAXO) / IAXO Collaboration
We review the physics potential of a next generation search for solar axions: the International Axion Observatory (IAXO). Endowed with a sensitivity to discover axion-like particles (ALPs) with a coupling to photons as small as $g_{a\gamma}\sim 10^{-12}$ GeV$^{-1}$, or to electrons $g_{ae}\sim$10$^{-13}$, IAXO has the potential to find the QCD axion in the 1 meV$\sim$1 eV mass range where it solves the strong CP problem, can account for the cold dark matter of the Universe and be responsible for the anomalous cooling observed in a number of stellar systems.

Planck 2018 results. I. Overview and the cosmological legacy of Planck / Planck Collaboration
The European Space Agency's Planck satellite, which was dedicated to studying the early Universe and its subsequent evolution, was launched on 14 May 2009. It scanned the microwave and submillimetre sky continuously between 12 August 2009 and 23 October 2013, producing deep, high-resolution, all-sky maps in nine frequency bands from 30 to 857GHz. [...]

Production cross sections of cosmic antiprotons in the light of new data from the NA61 and LHCb experiments / Korsmeier, Michael (INFN, Italy ; RWTH Aachen U. ; Turin U.) ; Donato, Fiorenza (INFN, Turin ; Turin U.) ; Di Mauro, Mattia (SLAC ; Stanford U., HEPL)
The cosmic-ray flux of antiprotons is measured with high precision by the space-borne particle spectrometers AMS-02.Its interpretation requires a correct description of the dominant production process for antiprotons in our Galaxy, namely, the interaction of cosmic-ray proton and helium with the interstellar medium. In the light of new cross section measurements by the NA61 experiment of $p + p \rightarrow \bar{p} + X$ and the first ever measurement of $p + \mathrm{He} \rightarrow \bar{p} + X$ by the LHCb experiment, we update the parametrization of proton-proton and proton-nucleon cross sections.We find that the LHCb $p$He data constrain a shape for the cross section at high energies and show for the first time how well the rescaling from the $pp$ channel applies to a helium target. [...]

Phase structure of complete asymptotically free SU($N_c$) theories with quarks and scalar quarks / Hansen, Frederik F. (Southern Denmark U., CP3-Origins) ; Janowski, Tadeusz (Southern Denmark U., CP3-Origins) ; Langæble, Kasper (Southern Denmark U., CP3-Origins) ; Mann, Robert B. (Waterloo U.) ; Sannino, Francesco (Southern Denmark U., CP3-Origins ; CERN ; U. Southern Denmark, Odense, DIAS) ; Steele, Tom G. (Saskatchewan U.) ; Wang, Zhi-Wei (Southern Denmark U., CP3-Origins ; Waterloo U.)
We determine the phase diagram of complete asymptotically free SU($N_c$) gauge theories featuring $N_s$ complex scalars and $N_f$ Dirac quarks transforming according to the fundamental representation of the gauge group. The analysis is performed at the maximum known order in perturbation theory. [...]

Measurement of the high-energy gamma-ray emission from the Moon with the Fermi Large Area Telescope / Fermi LAT Collaboration
We have measured the gamma-ray emission spectrum of the Moon using the data collected by the Large Area Telescope onboard the Fermi satellite during its first 7 years of operation, in the energy range from 30 MeV up to a few GeV. We have also studied the time evolution of the flux, finding a correlation with the solar activity. [...]

Planck 2015 results. XI. CMB power spectra, likelihoods, and robustness of parameters / Planck Collaboration
This paper presents the Planck 2015 likelihoods, statistical descriptions of the 2-point correlation functions of CMB temperature and polarization. They use the hybrid approach employed previously: pixel-based at low multipoles, $\ell$, and a Gaussian approximation to the distribution of cross-power spectra at higher $\ell$. [...]

Planck 2015 results. XXVI. The Second Planck Catalogue of Compact Sources / Planck Collaboration
The Second Planck Catalogue of Compact Sources is a catalogue of sources detected in single-frequency maps from the full duration of the Planck mission and supersedes previous versions of the Planck compact source catalogues. It consists of compact sources, both Galactic and extragalactic, detected over the entire sky. [...]

Planck 2015 results. XVI. Isotropy and statistics of the CMB / Planck Collaboration
We test the statistical isotropy and Gaussianity of the cosmic microwave background (CMB) anisotropies using observations made by the Planck satellite. Our results are based mainly on the full Planck mission for temperature, but also include some polarization measurements. [...]
