Self-Calibration of BICEP1 Three-Year Data and Constraints on Astrophysical Polarization Rotation
J. P. Kaufman, N. J. Miller, M. Shimon +33
Cosmic Microwave Background (CMB) polarimeters aspire to measure the faint -mode signature predicted to arise from inflationary gravitational waves. They also have the potential…
A no-go theorem for generalized vector Galileons on flat spacetime
Cedric Deffayet, A. Emir Gumrukcuoglu, Shinji Mukohyama +1
We explore the possibility for generalized electromagnetism on flat spacetime. For a single copy of gauge theory, we show that the Galileon-type generalization of electromag…
A Rare Encounter with Very Massive Stars in NGC 3125-A1
Aida Wofford, Claus Leitherer, Rupali Chandar +1
Super star cluster A1 in the nearby starburst galaxy NGC 3125 is characterized by broad He\ii \lam1640 emission (full width at half maximum, km s) of unpreced…
A Sub-Earth-Mass Moon Orbiting a Gas Giant Primary or a High Velocity Planetary System in the Galactic Bulge
D. P. Bennett, V. Batista, I. A. Bond +90
We present the first microlensing candidate for a free-floating exoplanet-exomoon system, MOA-2011-BLG-262, with a primary lens mass of M_host ~ 4 Jupiter masses hosting a sub-Eart…
Compressed convolution
F. Elsner, B. D. Wandelt
We introduce the concept of compressed convolution, a technique to convolve a given data set with a large number of non-orthogonal kernels. In typical applications our technique dr…
Identifying clustering at high redshift through actively star-forming galaxies
L. J. M. Davies, M. N. Bremer, E. R. Stanway +3
Identifying galaxy clustering at high redshift (i.e. z > 1) is essential to our understanding of the current cosmological model. However, at increasing redshift, clusters evolve co…
A Search for Methane in the Atmosphere of GJ 1214b via GTC Narrow-Band Transmission Spectrophotometry
P. A. Wilson, K. D. Colón, D. K. Sing +11
We present narrow-band photometric measurements of the exoplanet GJ 1214b using the 10.4 m Gran Telescopio Canarias (GTC) and the OSIRIS instrument. Using tuneable filters we obser…
Structure and substructure analysis of DAFT/FADA galaxy clusters in the [0.4-0.9] redshift range
L. Guennou, C. Adami, F. Durret +29
We analyse the structures of all the clusters in the DAFT/FADA survey for which XMM-Newton and/or a sufficient number of galaxy redshifts in the cluster range is available, with th…
Relative frequencies of supernovae versus properties of spiral hosts
A. A. Hakobyan, T. A. Nazaryan, V. Zh. Adibekyan +8
In this work, we present an analysis of SNe number ratios in spiral galaxies with different morphological subtypes, luminosities, sSFR, and metallicities, to provide important info…
The bright end of the galaxy luminosity function at z ~ 7: before the onset of mass quenching?
R. A . A. Bowler, J. S. Dunlop, R. J. McLure +9
We present the results of a new search for bright star-forming galaxies at z ~ 7 within the UltraVISTA DR2 and UKIDSS UDS DR10 data, which together provide 1.65 sq deg of near-infr…
Planck intermediate results. XVII. Emission of dust in the diffuse interstellar medium from the far-infrared to microwave frequencies
Planck Collaboration, A. Abergel, P. A. R. Ade +196
The dust-HI correlation is used to characterize the emission properties of dust in the diffuse interstellar medium. We cross-correlate sky maps from Planck, WMAP, and DIRBE, at 17…
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: Baryon Acoustic Oscillations in the Data Release 10 and 11 galaxy samples
Lauren Anderson, Eric Aubourg, Stephen Bailey +62
We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation…
Close pairs of galaxies with different activity levels
T. A. Nazaryan, A. R. Petrosian, A. A. Hakobyan +2
We selected and studied 180 pairs with dV < 800 km/s and Dp < 60 kpc containing Markarian (MRK) galaxies to investigate the dependence of galaxies' integral parameters, star-format…
Supernovae in paired galaxies
T. A. Nazaryan, A. R. Petrosian, A. A. Hakobyan +5
We investigate the influence of close neighbor galaxies on the properties of supernovae (SNe) and their host galaxies using 56 SNe located in pairs of galaxies with different level…
Spectral distortions in the cosmic microwave background polarization
Sebastien Renaux-Petel, Christian Fidler, Cyril Pitrou +1
We compute the spectral distortions of the Cosmic Microwave Background (CMB) polarization induced by non-linear effects in the Compton interactions between CMB photons and cold int…
The Best Inflationary Models After Planck
Jerome Martin, Christophe Ringeval, Roberto Trotta +1
We compute the Bayesian evidence and complexity of 193 slow-roll single-field models of inflation using the Planck 2013 Cosmic Microwave Background data, with the aim of establishi…
Half-integral conservative post-Newtonian approximations in the redshift factor of black hole binaries
Luc Blanchet, Guillaume Faye, Bernard F. Whiting
Recent perturbative self-force computations (Shah, Friedman & Whiting, submitted to Phys. Rev. {\bf D}, arXiv:1312.1952 [gr-qc]), both numerical and analytical, have determined tha…
Finding high-order analytic post-Newtonian parameters from a high-precision numerical self-force calculation
