First test of Verlinde's theory of Emergent Gravity using Weak Gravitational Lensing measurements
Margot M. Brouwer, Manus R. Visser, Andrej Dvornik +19
Verlinde (2016) proposed that the observed excess gravity in galaxies and clusters is the consequence of Emergent Gravity (EG). In this theory the standard gravitational laws are m…
Discovery of a supercluster in the ZOA in Vela
Renée C. Kraan-Korteweg, Michelle E. Cluver, Maciej Bilicki +5
We report the discovery of a potentially major supercluster that extends across the Galactic Plane in the constellation of Vela, at a mean recessional velocity of ~18,000 km/s. Rec…
The 2-degree Field Lensing Survey: photometric redshifts from a large new training sample to r<19.5
Christian Wolf, Andrew Johnson, Maciej Bilicki +13
We present a new training set for estimating empirical photometric redshifts of galaxies, which was created as part of the 2dFLenS project. This training set is located in a 700 sq…
Cross-correlation of weak lensing and gamma rays: implications for the nature of dark matter
Tilman Tröster, Stefano Camera, Mattia Fornasa +12
We measure the cross-correlation between Fermi-LAT gamma-ray photons and over 1000 deg of weak lensing data from the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS), t…
The Astropy Problem
Demitri Muna, Michael Alexander, Alice Allen +151
The Astropy Project (http://astropy.org) is, in its own words, "a community effort to develop a single core package for Astronomy in Python and foster interoperability between Pyth…
Not a Copernican observer: biased peculiar velocity statistics in the local Universe
Wojciech A. Hellwing, Adi Nusser, Martin Feix +1
We assess the effect of the local large scale structure on the estimation of two-point statistics of the observed radial peculiar velocities of galaxies. A large N-body simulation…
