Statistics of Microlensing Caustic Crossings in Q~2237+0305: Peculiar Velocity of the Lens Galaxy and Accretion Disk Size

E. Mediavilla, J. Jimenez-Vicente, J. A. Muñoz +2

We use the statistics of caustic crossings induced by microlensing in the lens system Q~2237+0305 to study the lens galaxy peculiar velocity. We calculate the caustic crossing rate…

Planck intermediate results. XXX. The angular power spectrum of polarized dust emission at intermediate and high Galactic latitudes

Planck Collaboration, R. Adam, P. A. R. Ade +230

The polarized thermal emission from Galactic dust is the main foreground present in measurements of the polarization of the cosmic microwave background (CMB) at frequencies above 1…

Theory of non-Gaussianity in warm inflation

Mar Bastero-Gil, Arjun Berera, Ian G. Moss +1

The theory and methodology is developed to compute the bispectrum in warm inflation, leading to results for the non-linearity parameter and the shape of the bispectrum. Particular…

Planck intermediate results. XXVI. Optical identification and redshifts of Planck clusters with the RTT150 telescope

Planck Collaboration, P. A. R. Ade, N. Aghanim +194

We present the results of approximately three years of observations of Planck Sunyaev-Zeldovich (SZ) sources with the Russian-Turkish 1.5-m telescope (RTT150), as a part of the opt…

Planck intermediate results. XXIV. Constraints on variation of fundamental constants

P. A. R. Ade, N. Aghanim, M. Arnaud +166

Any variation of the fundamental physical constants, and more particularly of the fine structure constant, , or of the mass of the electron, , would affect the recombinatio…

Observational implications of mattergenesis during inflation

Mar Bastero-Gil, Arjun Berera, Rudnei O. Ramos +1

The observed baryon asymmetry, as well as potentially an asymmetry in the dark matter sector, can be produced through dissipative particle production during inflation. A distinctiv…

Effects of the environment on galaxies in the Catalogue of Isolated Galaxies: physical satellites and large scale structure

M. Argudo-Fernández, S. Verley, G. Bergond +8

We aim to identify and quantify the effects of the satellite distribution around a sample of galaxies in the Catalogue of Isolated Galaxies (CIG), as well as the effects of the Lar…

The Average Size and Temperature Profile of Quasar Accretion Disks

J. Jiménez-Vicente, E. Mediavilla, C. S. Kochanek +4

We use multi-wavelength microlensing measurements of a sample of 10 image pairs from 8 lensed quasars to study the structure of their accretion disks. By using spectroscopy or narr…

Cosmological fluctuations of a random field and radiation fluid

Mar Bastero-Gil, Arjun Berera, Ian G. Moss +1

A generalization of the random fluid hydrodynamic fluctuation theory due to Landau and Lifshitz is applied to describe cosmological fluctuations in systems with radiation and scala…
