Subaru weak-lensing study of A2163: bimodal mass structure
Subaru weak-lensing study A2163 bimodal mass structure
2011/8/24
We present a weak-lensing analysis of the merging cluster A2163 using Subaru/Suprime-Cam and CHFT/Mega-Cam data and discuss the dynamics of this cluster merger, based on complementary weak-lensing, X-...

Context. Palomar 1 is a peculiar globular cluster (GC). It is the youngest Galactic GC and it has been tentatively associated to several of the substructures recently discovered in the Milky Way (MW),...
The Subaru Ly-alpha blob survey: A sample of 100 kpc Ly-alpha blobs at z=3
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
We present results of a survey for giant Ly-alpha nebulae (LABs) at z=3 with Subaru/Suprime-Cam. We obtained Ly-alpha imaging at z=3.09+-0.03 around the SSA22 protocluster and in several blank fields.
