Observational Evidence for a Galaxy Overdensity/Protocluster at z=6.5
We present the results of our search near the end of the Reionization Epoch for faint galaxies around two close, massive Lyman-α emitters (LAEs) at redshift 6.5...
Observational evidence for stellar-mass black holes
Radial velocity studies of X-ray binaries still provide the most solid evidence for the existence of stellar-mass black holes. We currently have 20 confirmed...
Observational Evidence for the "Hot Wall" Effect in Small Magnetic Flux Concentrations
Introduction: When lacking polarimetric observations, the Bright Points (BPs) visible in the G-band at 430 nm are commonly used as tracers for magnetic fields...
The authors discuss recent evidence that the massive star formation in the grand-design spiral galaxy M51 is triggered. Studying the symmetry of the Hα...
Observational evidence of different formation mechanisms of Solar System-type architectures across spectral types
Despite being the most abundant classes of known exoplanets, super-Earths and mini-Neptunes are absent in our Solar System, and the exact reason for this is...
This paper summarizes the common properties of the currently known galactic black hole candidates. Particular emphasis is given to optical studies of the best...
