Description
We report some recent of the Tenerife experiments. On a strip at Dec = +40° we have identified structure in the microwave sky at several frequencies. Clear evidence is found for a feature centred at RA 185° with a peak amplitude of 80 K. A statistical analysis of the data at this declination reveals the presence of signal at an rms of 42 ± 9 K. Assuming a model of a Harrison-Zeldovich spectrum of fluctuations, we infer an expected quadrupole term of 25-7+9 K. The radiometers are now observing adjacent bands of the sky separated 2.5 degrees in declination; some of the preliminary results obtained in these adjacent scans are discussed.

    Detection of Na in the atmosphere of the hot Jupiter HAT-P-55b
    The spectral signatures of optical absorbers, when combined with those of infrared molecules, play a critical role in constraining the cloud properties of exoplanet atmospheres. We aim to use optical transmission spectroscopy to confirm the tentative color signature previously observed by multiband photometry in the atmosphere of hot Jupiter HAT-P

    The COSMOS-Web ring: In-depth characterization of an Einstein ring lensing system at z ∼ 2
    Aims: We provide an in-depth analysis of the COSMOS-Web ring, an Einstein ring at z ≈ 2 that we serendipitously discovered during the data reduction of the COSMOS-Web survey and that could be the most distant lens discovered to date. Methods: We extracted the visible and near-infrared photometry of the source and the lens from more than 25 bands

    Migration and Evolution of giant ExoPlanets (MEEP). I. Nine Newly Confirmed Hot Jupiters from the TESS Mission
    Hot Jupiters were many of the first exoplanets discovered in the 1990s, but in the decades since their discovery the mysteries surrounding their origins have remained. Here we present nine new hot Jupiters (TOI-1855 b, TOI-2107 b, TOI-2368 b, TOI-3321 b, TOI-3894 b, TOI-3919 b, TOI-4153 b, TOI-5232 b, and TOI-5301 b) discovered by NASA's TESS
