FRIDA (inFRared Imager and Dissector for the Adaptive optics system of the GTC) will be a NIR (1-2.5 μm) imager and Integral Field Unit spectrograph to operate...
Data treatment towards the ELT age. The ESPRESSO case
Several ambitious scientific projects are currently pushing the limits of astrophysical spectroscopy, in terms of wavelength accuracy and long-term stability...
The photometric decay of sunspots is studied in some detail. Aspects related to leader vs. follower sunspot decay are presented and our current understanding of...
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 behavior 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...
