Compressive sensing for spectroscopy and polarimetry
We demonstrate, through numerical simulations with real data, the feasibility of using compressive sensing techniques for the acquisition of spectro...
Context. CarbON CII line in post-rEionisation and ReionisaTiOn epoch (CONCERTO) instrument is a low-resolution mapping spectrometer based on lumped element...
Confidence levels of evolutionary synthesis models
The stochastic nature of the IMF in young stellar clusters implies that clusters of the same mass and age do not present the same unique values of their...
Confidence levels of evolutionary synthesis models. II. On sampling and Poissonian fluctuations
In terms of statistical fluctuations, stellar population synthesis models are only asymptotically correct in the limit of a large number of stars, where...
Confidence limits of evolutionary synthesis models. III. On time-integrated quantities
Evolutionary synthesis models are a fundamental tool to interpret the properties of observed stellar systems. In order to achieve a meaningful comparison...
Confidence limits of evolutionary synthesis models. IV. Moving forward to a probabilistic formulation
Context: .Synthesis models predict the integrated properties of stellar populations. Several problems exist in this field, mostly related to the fact that...
Confirmation and characterisation of three giant planets detected by TESS from the FIES/NOT and Tull/McDonald spectrographs
We report the confirmation and characterisation of TOI-1820 b, TOI-2025 b, and TOI-2158 b, three Jupiter-sized planets on short-period orbits around G-type...
Confirmation of an exoplanet using the transit color signature: Kepler-418b, a blended giant planet in a multiplanet system
Aims: We announce confirmation of Kepler-418b, one of two proposed planets in this system. This is the first confirmation of an exoplanet based primarily on the...
Confirmation of an He I evaporating atmosphere around the 650-Myr-old sub-Neptune HD 235088 b (TOI-1430 b) with CARMENES
HD 235088 (TOI-1430) is a young star known to host a sub-Neptune-sized planet candidate. We validated the planetary nature of HD 235088 b with multiband...
