    A hot mini-Neptune and a temperate, highly eccentric sub-Saturn around the bright K-dwarf TOI-2134
    We present the characterization of an inner mini-Neptune in a 9.2292005 ± 0.0000063 d orbit and an outer mono-transiting sub-Saturn planet in a 95.50$^{+0.36}_{...

    A machine learning approach to galaxy properties: joint redshift-stellar mass probability distributions with Random Forest
    We demonstrate that highly accurate joint redshift-stellar mass probability distribution functions (PDFs) can be obtained using the Random Forest (RF) machine...

    A meta-analysis of the magnetic line broadening in the solar atmosphere
    A multiline Bayesian analysis of the Zeeman broadening in the solar atmosphere is presented. A hierarchical probabilistic model, based on the simple but...

    A method to detect p-mode oscillations in solar-like star signals
    A good example of finding a signal buried in noise, a common problem in Astrophysics, is the search for stellar oscillations in the acoustic power spectrum of...

    A modified χ2-test for cosmic microwave background analyses
    We present a new general procedure for determining a given set of quantities. To this end, we define a certain statistic, which we call `modified χ2' (χ2M)...

    A multi-wavelength analysis of M 81: insight on the nature of Arp's loop
    Context. The optical ring-like structure detected by Arp (1965) around M 81 (commonly referenced as “Arp's loop”) represents one of the most spectacular...

    A multifrequency maximum-entropy joint analysis of COBE and Tenerife data
    We use data from the Tenerife 10-, 15- and 33-GHz beam-switching experiments along with the COBE 53- and 90-GHz data to separate the cosmic microwave background...
