280 one-opposition near-Earth asteroids recovered by the EURONEAR with the Isaac Newton Telescope
O. Vaduvescu, L. Hudin, T. Mocnik +80
One-opposition near-Earth asteroids (NEAs) are growing in number, and they must be recovered to prevent loss and mismatch risk, and to improve their orbits, as they are likely to b…
The galaxy-subhalo connection in low-redshift galaxy clusters from weak gravitational lensing
Cristóbal Sifón, Ricardo Herbonnet, Henk Hoekstra +2
We measure the gravitational lensing signal around satellite galaxies in a sample of galaxy clusters at by combining high-quality imaging data from the Canada-France-Hawai…
A first constraint on the average mass of ultra diffuse galaxies from weak gravitational lensing
Cristóbal Sifón, Remco F. J. van der Burg, Henk Hoekstra +2
The recent discovery of thousands of ultra diffuse galaxies (UDGs) in nearby galaxy clusters has opened a new window into the process of galaxy formation and evolution. Several sce…
A KiDS weak lensing analysis of assembly bias in GAMA galaxy groups
Andrej Dvornik, Marcello Cacciato, Konrad Kuijken +19
We investigate possible signatures of halo assembly bias for spectroscopically selected galaxy groups from the GAMA survey using weak lensing measurements from the spatially overla…
