The edge of the M87 halo and the kinematics of the diffuse light in the Virgo cluster core
, 2009 We present high resolution FLAMES/VLT spectroscopy of intracluster planetary nebula (ICPN) candidates, targeting three new fields in the Virgo cluster core with surface brightness down to mu_B = 28.5.

Radar Automatic Target Open Set Recognition Based on Cluster Boundary Detection
IEEE AccessRadar automatic target recognition has developed significantly in recent years. Previous works mainly aim at addressing the closed set recognition problem, whose test set and training set have the same categories of the targets.

Single-cycle atomic force microscope force reconstruction: resolving time-dependent interactions
New Journal of Physics, 2013 Here, we enhance the capabilities of the atomic force microscope (AFM) to show that force profiles can be reconstructed without restriction by monitoring the wave profile of the cantilever during a single oscillation cycle. Two approaches are provided to

Turbulence in Clusters of Galaxies and X-Ray Line Profiles
, 2003 Large-scale bulk motions and hydrodynamic turbulence in the intergalactic gas inside clusters of galaxies significantly broaden X-ray emission lines. For lines of heavy ions (primarily helium-like and hydrogen-like iron ions), the hydrodynamic broadening
