Various possible decay laws (exponential, linear, parabolic) are tried to fit the observational material. The dependence of the decay rates on the spot's...
The global behaviour and fine structure of the distribution of sunspot decay rates from activity cycle 13 to 20 are presented. It is shown that the distribution...

Deciphering Quasar Millilensing How to Distinguish Between Dark and Luminous Lenses
Dwarf-galaxy sized dark matter halos may be detectable when a bright background source is gravitationally lensed on scales of milliarcseconds. Such effects can...
Deciphering TNOs thermal evolution through Centaur surface studies using JWST
This research explores the surface properties of ten Centaurs through their reflective properties in the 0.6-5.3 μm range obtained using the JWST/NIRSpec...
We present a study that links the Number Counts (NCs) to the rest-frame luminosity functions (LFs) at the passbands probed by the observed K-band at different...
The black hole binary V404 Cyg has provided a primary test bed for models of accretion in quiescent black hole binaries because it is by far the brightest in...
Decoupling luminosity, evolution and orientation effects in AGN
With this proposal we will decouple luminosity effects from evolutionary effects in matched samples of radio-loud and radio-quiet quasars, and determine the...
