MASCARA-1 b. A hot Jupiter transiting a bright mV = 8.3 A-star in a misaligned orbit
Snellen, I. A. G.; Grundahl, F.; Albrecht, S. +11 more
We report the discovery of MASCARA-1 b, which is the first exoplanet discovered with the Multi-site All-Sky CAmeRA (MASCARA). This exoplanet is a hot Jupiter orbiting a bright mV = 8.3, rapidly rotating (vsini⋆ > 100 km s-1) A8 star with a period of 2.148780 ± 8 × 10-6 days. The planet has a mass and …
The Clouds are breaking: tracing the Magellanic system with Gaia DR1 Mira variables
Erkal, Denis; Belokurov, Vasily; Mackey, Dougal +2 more
We exploit the first data release from the Gaia mission to identify candidate Mira variables in the outskirts of the Magellanic Clouds. The repeated observations of sources during the initial phase of the Gaia mission is used to identify stars that show signs of variability. This variability information, combined with infrared photometry from Two …
The clustering of galaxies in the completed SDSS-III Baryon Oscillation Spectroscopic Survey: angular clustering tomography and its cosmological implications
Brownstein, Joel R.; Thomas, Daniel; Prada, Francisco +17 more
We investigate the cosmological implications of studying galaxy clustering using a tomographic approach applied to the final Baryon Oscillation Spectroscopic Survey (BOSS) DR12 galaxy sample, including both auto- and cross-correlation functions between redshift shells. We model the signal of the full shape of the angular correlation function, ω(θ)…
Complete reionization constraints from Planck 2015 polarization
Heinrich, Chen He; Miranda, Vinicius; Hu, Wayne
We conduct an analysis of the Planck 2015 data that is complete in reionization observables from the large angle polarization E -mode spectrum in the redshift range 6 <z <30 . Based on 5 principal components, all of which are constrained by the data, this single analysis can be used to infer constraints on any model for reionization in the s…
Modelling clumpy photon-dominated regions in 3D. Understanding the Orion Bar stratification
Röllig, M.; Ossenkopf-Okada, V.; Andree-Labsch, S.
Context. Models of photon-dominated regions (PDRs) still fail to fully reproduce some of the observed properties. In particular they do not reproduce the combination of the intensities of different PDR cooling lines together with the chemical stratification, as observed for example for the Orion Bar PDR.
Aims: We aim to construct a numerical …
True polar wander of Enceladus from topographic data
Hedman, Matthew M.; Schenk, Paul M.; Burns, Joseph A. +4 more
Many objects in the solar system are suspected to have experienced reorientation of their spin axes. As their rotation rates are slow and their shapes are nearly spherical, the formation of mass anomalies, by either endogenic or exogenic processes, can change objects' moments of inertia. Therefore, the objects reorient to align their largest momen…
Spatially Resolved Kinematics in the Central 1 kpc of a Compact Star-forming Galaxy at z ∼2.3 from ALMA CO Observations
Rujopakarn, W.; Faber, S. M.; Dekel, A. +9 more
We present high spatial resolution (FWHM ∼ 0.″14) observations of the CO(8-7) line in GDS-14876, a compact star-forming galaxy at z = 2.3 with a total stellar mass of log(M ⋆/M ⊙) = 10.9. The spatially resolved velocity map of the inner r ≲ 1 kpc reveals a continuous velocity gradient consistent with the kinematics of a rotat…
FIGS—Faint Infrared Grism Survey: Description and Data Reduction
Finkelstein, Steven L.; Hathi, Nimish P.; Koekemoer, Anton M. +26 more
The Faint Infrared Grism Survey (FIGS) is a deep Hubble Space Telescope (HST) WFC3/IR (Wide Field Camera 3 Infrared) slitless spectroscopic survey of four deep fields. Two fields are located in the Great Observatories Origins Deep Survey-North (GOODS-N) area and two fields are located in the Great Observatories Origins Deep Survey-South (GOODS-S) …
Cosmological parameters from pre-Planck CMB measurements: A 2017 update
Bond, J. Richard; Devlin, Mark J.; Dunkley, Joanna +15 more
We present cosmological constraints from the combination of the full mission nine-year WMAP release and small-scale temperature data from the pre-Planck Atacama Cosmology Telescope (ACT) and South Pole Telescope (SPT) generation of instruments. This is an update of the analysis presented in Calabrese et al. [Phys. Rev. D 87, 103012 (2013), 10.1103…
Imprint of DES superstructures on the cosmic microwave background
Benoit-Lévy, A.; Bacon, D.; D'Andrea, C. B. +61 more
Small temperature anisotropies in the cosmic microwave background (CMB) can be sourced by density perturbations via the late-time integrated Sachs-Wolfe (ISW) effect. Large voids and superclusters are excellent environments to make a localized measurement of this tiny imprint. In some cases excess signals have been reported. We probed these claims…
