Observational Cosmology: caveats and open questions in the standard model
I will review some results of observational cosmology which critically cast doubt upon the foundations of the standard cosmology: 1) The redshifts of the...
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...
