H0LiCOW XII. Lens mass model of WFI2033-4723 and blind measurement of its time-delay distance and H-0

Frédéric Courbin, Hung-Hsu Chan, Vivien François Bonvin

We present the lens mass model of the quadruply-imaged gravitationally lensed quasar WFI2033 - 4723, and perform a blind cosmographical analysis based on this system. Our analysis combines (1) time-delay measurements from 14 yr of data obtained by the COSm ...

LSST: From Science Drivers to Reference Design and Anticipated Data Products

David Atienza Alonso, Jonathan Andrew Blazek, Darong Huang, Shahram Khazaei

We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). The LSST design is driven by four main science themes: probing dark energy and dark matter, taking an inventory of the solar system, ex ...

The Pristine survey - I. Mining the Galaxy for the most metal-poor stars

Pascale Jablonka, Nicolas Lawrence Etienne Longeard

We present the Pristine survey, a new narrow-band photometric survey focused on the metallicity-sensitive Ca H&K lines and conducted in the Northern hemisphere with the wide-field imager MegaCam on the Canada-France-Hawaii Telescope. This paper reviews our ...

Extreme laser spectral broadening driven by intense THz field

Christoph Peter Hauri

We present giant spectral broadening by cross phase modulation of a 60 fs nIR pulse in GaP by means of an intense Terahertz transient. The THz field induces up to 500% spectral broadening supporting sub-10 fs nIR pulses. ...

MULTIWAVELENGTH STUDY OF QUIESCENT STATES OF Mrk 421 WITH UNPRECEDENTED HARD X-RAY COVERAGE PROVIDED BY NuSTAR IN 2013

Xin Chen, Thomas Günther Bretz

We present coordinated multiwavelength observations of the bright, nearby BL Lacertae object Mrk 421 taken in 2013 January-March, involving GASP-WEBT, Swift, NuSTAR, Fermi-LAT, MAGIC, VERITAS, and other collaborations and instruments, providing data from r ...

THE LYMAN ALPHA REFERENCE SAMPLE V. THE IMPACT OF NEUTRAL ISM KINEMATICS AND GEOMETRY ON Ly alpha ESCAPE

Hakim Atek

We present high-resolution far-UV spectroscopy of the 14 galaxies of the Ly alpha Reference Sample; a sample of strongly star-forming galaxies at low redshifts (0.028 < z < 0.18). We compare the derived properties to global properties derived from multi-ba ...

IceCube sensitivity for neutrino flux from Fermi blazars in quiescent states

Mathieu Ribordy

We investigate the IceCube detection potential of very high energy neutrinos from blazars, for different classes of hadronic models, taking into account the limits imposed on the neutrino flux by the recent Fermi telescope observations. Assuming the observ ...

The Low-Mass Initial Mass Function In The 30 Doradus Starburst Cluster

Marilyne Andersen, Georges Meylan

We present deep Hubble Space Telescope NICMOS 2 F160W band observations of the central 56 '' x 57 '' (14 pc x 14.25 pc) region around R136 in the starburst cluster 30Dor (NGC 2070) located in the Large Magellanic Cloud. Our aim is to derive the stellar ini ...
