Morphological Segregation in the Surroundings of Cosmic Voids

We explore the morphology of galaxies living in the proximity of cosmic voids, using a sample of voids identified in the Sloan Digital Sky Survey Data Release 7. At all stellar masses, void galaxies exhibit morphologies of a later type than galaxies in a c ...

Photometric redshifts and clustering of emission line galaxies selected jointly by DES and eBOSS

Yi Zhang, Jean-Paul Richard Kneib, Eduardo Sanchez, Johan Comparat, Timothée Guy Olivier Delubac

We present the results of the first observations of the emission line galaxies (ELG) of the extended Baryon Oscillation Spectroscopic Survey. From the total 9000 targets, 4600 have been selected from the Dark Energy Survey (DES). In this subsample, the tot ...

Potential Recoiling Supermassive Black Hole, CXO J101527.2+625911

David Richard Harvey

We have carried out a systematic search for recoiling supermassive black holes (rSMBH) using the Chandra Source and SDSS Cross-Match Catalog. From the survey, we have detected a potential rSMBH, CXO J101527.2 +625911, at z = 0.3504. The source CXO J101527. ...

Stellar-to-halo mass relation of cluster galaxies

Jean-Paul Richard Kneib, Huanyuan Shan

In the formation of galaxy groups and clusters, the dark matter haloes containing satellite galaxies are expected to be tidally stripped in gravitational interactions with the host. We use galaxy-galaxy weak lensing to measure the average mass of dark matt ...

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

Frédéric Courbin, Adriano Agnello

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 ...

Testing Lorentz invariance of dark matter with satellite galaxies

Sergey Sibiryakov, Diego Blas Temino

We develop the framework for testing Lorentz invariance in the dark matter sector using galactic dynamics. We consider a Lorentz violating (LV) vector field acting on the dark matter component of a satellite galaxy orbiting in a host halo. We introduce a n ...

Discovery of the Lensed Quasar System DES J0408-5354

Eduardo Sanchez, Frédéric Courbin, Georges Meylan, Hung-Hsu Chan, Adriano Agnello

We report the discovery and spectroscopic confirmation of the quad-like lensed quasar system DES J0408-5354 found in the Dark Energy Survey (DES) Year 1 (Y1) data. This system was discovered during a search for DES Y1 strong lensing systems using a method ...

A test for skewed distributions of dark matter, and a possible detection in galaxy cluster Abell 3827

Frédéric Courbin, David Richard Harvey, Mathilde Jauzac, Rémy Elie Joseph, Richard Massey

Simulations of self-interacting dark matter predict that dark matter should lag behind galaxies during a collision. If the interaction is mediated by a high-mass force carrier, the distribution of dark matter can also develop asymmetric dark matter tails. ...
