H0LiCOW. VI. Testing the fidelity of lensed quasar host galaxy reconstruction

The empirical correlation between the mass of a supermassive black hole (M-BH) and its host galaxy properties is widely considered to be an evidence of their co-evolution. A powerful way to test the co-evolution scenario and learn about the feedback proces ...

Models of the strongly lensed quasar DES J0408-5354

Eduardo Sanchez, Frédéric Courbin, Georges Meylan, Cameron Alexander Campbell Lemon, Hung-Hsu Chan, Vivien François Bonvin, Adriano Agnello

We present detailed modelling of the recently discovered, quadruply lensed quasar J0408-5354, with the aim of interpreting its remarkable configuration: besides three quasar images (A, B, D) around the main deflector (G1), a fourth image (C) is significant ...

The Spitzer-Irac/Mips Extragalactic Survey (Simes) In The South Ecliptic Pole Field

Hakim Atek

We present the Spitzer-IRAC/MIPS Extragalactic survey (SIMES) in the South Ecliptic Pole field. The large area covered (7.7 deg(2)), together with one of the lowest Galactic cirrus emissions in the entire sky and a very extensive coverage by Spitzer, Hersc ...

Evaluating the effect of stellar multiplicity on the point spread function of space-based weak lensing surveys

Frédéric Courbin, Georges Meylan, Thibault Adrien Kuntzer

The next generation of space-based telescopes used for weak lensing surveys will require exquisite point spread function (PSF) determination. Previously negligible effects may become important in the reconstruction of the PSF, in part because of the improv ...

Operation of a Concurrent Design Facility for university projects

Louis Antoine Masson, Anton Ivanov, Federico Belloni

Concurrent Design is a part of the systems engineering process, which has been widely adopted in space mission design. This paper describes the setting up a facility in a university and will try to answer a question of where the Concurrent Design Facility ...

A General Framework for Compressed Sensing and Parallel MRI Using Annihilating Filter Based Low-Rank Hankel Matrix

Kyong Hwan Jin

Parallel MRI (pMRI) and compressed sensing MRI (CS-MRI) have been considered as two distinct reconstruction problems. Inspired by recent k-space interpolation methods, an annihilating filter-based low-rank Hankel matrix approach is proposed as a general fr ...

ARE ULTRA-FAINT GALAXIES AT z=6-8 RESPONSIBLE FOR COSMIC REIONIZATION? COMBINED CONSTRAINTS FROM THE HUBBLE FRONTIER FIELDS CLUSTERS AND PARALLELS

Jean-Paul Richard Kneib, Benjamin Yvan Alexandre Clement, Mathilde Jauzac, Hakim Atek, Johan Richard

We use deep Hubble Space Telescope imaging of the Frontier Fields to accurately measure the galaxy rest-frame ultraviolet luminosity function (UV LF) in the redshift range z similar to 6-8. We combine observations in three lensing clusters, A2744, MACS 041 ...

NEW CONSTRAINTS ON THE FAINT END OF THE UV LUMINOSITY FUNCTION AT z similar to 7-8 USING THE GRAVITATIONAL LENSING OF THE HUBBLE FRONTIER FIELDS CLUSTER A2744

Jean-Paul Richard Kneib, Benjamin Yvan Alexandre Clement, Mathilde Jauzac, Hakim Atek, Johan Richard

Exploiting the power of gravitational lensing, the Hubble Frontier Fields (HFF) program aims at observing six massive galaxy clusters to explore the distant universe far beyond the limits of blank field surveys. Using the complete Hubble Space Telescope ob ...

Discovery of two gravitationally lensed quasars in the Dark Energy Survey

Yi Zhang, Eduardo Sanchez, Frédéric Courbin, Georges Meylan, Adriano Agnello

We present spectroscopic confirmation of two new gravitationally lensed quasars, discovered in the Dark Energy Survey (DES) and Wide-field Infrared Survey Explorer (WISE) based on their multiband photometry and extended morphology in DES images. Images of ...
