Star formation towards the Galactic HII region RCW120
M. Figueira, A. Zavagno, L. Deharveng +16
The expansion of HII regions can trigger the formation of stars. An overdensity of young stellar objects (YSOs) is observed at the edges of HII regions but the mechanisms that give…
Testing Predictions of the Quantum Landscape Multiverse 2: The Exponential Inflationary Potential
Eleonora Di Valentino, Laura Mersini-Houghton
The 2015 Planck data release tightened the region of the allowed inflationary models. Inflationary models with convex potentials have now been ruled out since they produce a large…
Planck intermediate results. LII. Planet flux densities
Planck Collaboration, Y. Akrami, M. Ashdown +147
Measurements of flux density are described for five planets, Mars, Jupiter, Saturn, Uranus, and Neptune, across the six Planck High Frequency Instrument frequency bands (100-857 GH…
Challenges in Cosmology from the Big Bang to Dark Energy, Dark Matter and Galaxy Formation
Joseph Silk
I review the current status of Big Bang Cosmology, with emphasis on current issues in dark matter, dark energy, and galaxy formation. These topics motivate many of the current goal…
Metallicity-dependendent kinematics and morphology of the Milky Way bulge
E. Athanassoula, S. A. Rodionov, N. Prantzos
We use N-body chemo-dynamic simulations to study the coupling between morphology, kinematics and metallicity of the bar/bulge region of our Galaxy. We make qualitative comparisons…
Cosmological constraints with weak lensing peak counts and second-order statistics in a large-field survey
Austin Peel, Chieh-An Lin, Francois Lanusse +3
Peak statistics in weak lensing maps access the non-Gaussian information contained in the large-scale distribution of matter in the Universe. They are therefore a promising complem…
Causal structures in cosmology
George Ellis, Jean-Philippe Uzan
This article reviews the properties and limitations associated with the existence of particle, visual, and event horizons in cosmology in general and in inflationary universes in p…
First Detection of Hydrogen in the β Pictoris Gas Disk
P. A. Wilson, A. Lecavelier des Etangs, A. Vidal-Madjar +6
The young and nearby star β Pictoris (β Pic) is surrounded by a debris disk composed of dust and gas known to host a myriad evaporating exocomets, planetesimals and at least one pl…
Testing Predictions of the Quantum Landscape Multiverse 1: The Starobinsky Inflationary Potential
Eleonora Di Valentino, Laura Mersini-Houghton
The 2015 Planck data release has placed tight constraints on the allowed class of inflationary models. The current data favors concave downwards inflationary potentials while offer…
Exploring Cosmic Origins with CORE: Inflation
CORE Collaboration, Fabio Finelli, Martin Bucher +129
We forecast the scientific capabilities to improve our understanding of cosmic inflation of CORE, a proposed CMB space satellite submitted in response to the ESA fifth call for a m…
Weak lensing and spectroscopic analysis of the nearby dissociative merging galaxy cluster Abell 3376
Rogério Monteiro-Oliveira, Gastão B. Lima Neto, Eduardo S. Cypriano +5
The galaxy cluster Abell~3376 is a nearby (z=0.046) dissociative merging cluster surrounded by two prominent radio relics and showing an X-ray comet-like morphology. The merger sys…
Speed from light: growth rate and bulk flow at z ~ 0.1 from improved SDSS DR13 photometry
Martin Feix, Enzo Branchini, Adi Nusser
Observed galaxy luminosities (derived from redshifts) hold information on the large-scale peculiar velocity field in the form of spatially correlated scatter, which allows for boun…
Dark Matter's secret liaisons: phenomenology of a dark U(1) sector with bound states
Marco Cirelli, Paolo Panci, Kalliopi Petraki +2
Dark matter (DM) charged under a dark U(1) force appears in many extensions of the Standard Model, and has been invoked to explain anomalies in cosmic-ray data, as well as a self-i…
Cluster-Void Degeneracy Breaking: Modified Gravity in the Balance
Martin Sahlén, Joseph Silk
Combining galaxy cluster and void abundances is a novel, powerful way to constrain deviations from General Relativity and the CDM model. For a flat CDM model with growth of l…
Stochastic gravitational waves associated with the formation of primordial black holes
Tomohiro Nakama, Joseph Silk, Marc Kamionkowski
Primordial black hole (PBH) mergers have been proposed as an explanation for the gravitational wave events detected by the LIGO collaboration. Such PBHs may be formed in the early…
CMB Lens Sample Covariance and Consistency Relations
Pavel Motloch, Wayne Hu, Aurélien Benoit-Lévy
Gravitational lensing information from the two and higher point statistics of the CMB temperature and polarization fields are intrinsically correlated because they are lensed by th…
New terms for scalar multi-Galileon models and application to SO(N) and SU(N) group representations
Erwan Allys
We investigate a new class of scalar multi-galileon models, which is not included in the commonly admitted general formulation of generalized multi-galileons. The Lagrangians of th…
Molecular Gas in the Halo Fuels the Growth of a Massive Cluster Galaxy at High Redshift
B. H. C. Emonts, M. D. Lehnert, M. Villar-Martin +19
The largest galaxies in the Universe reside in galaxy clusters. Using sensitive observations of carbon-monoxide, we show that the Spiderweb Galaxy -a massive galaxy in a distant pr…
Exploring Cosmic Origins with CORE: Cosmological Parameters
Eleonora Di Valentino, Thejs Brinckmann, Martina Gerbino +125
We forecast the main cosmological parameter constraints achievable with the CORE space mission which is dedicated to mapping the polarisation of the Cosmic Microwave Background (CM…
Two is better than one: joint statistics of density and velocity in concentric spheres as a cosmological probe
Cora Uhlemann, Sandrine Codis, Oliver Hahn +2
The analytical formalism to obtain the probability distribution functions (PDFs) of spherically-averaged cosmic densities and velocity divergences in the mildly non-linear regime i…
The Atacama Cosmology Telescope: Two-Season ACTPol Lensing Power Spectrum
Blake D. Sherwin, Alexander van Engelen, Neelima Sehgal +43
We report a measurement of the power spectrum of cosmic microwave background (CMB) lensing from two seasons of Atacama Cosmology Telescope Polarimeter (ACTPol) CMB data. The CMB le…
AGN feedback and the origin of the enhancement in early type galaxies - insights from the GAEA model
Gabriella De Lucia, Fabio Fontanot, Michaela Hirschmann
We take advantage of our recently published model for Galaxy Evolution and Assembly (GAEA) to study the origin of the observed correlation between [/Fe] and galaxy stellar mass.…
