Descripción
In order to test the calibration technique to be used on the GOLF solar oscillation resonant scattering spectrometer on the SOHO mission, observations with a modified instrument have been carried out at Izana, Tenerife since 1989. Different methods of analysing data are compared. These show that calibration by means of a magnetic modulation technique is effective in reducing the noise level in that part of the frequency spectrum where the gravity modes are to be sought.

    An ultra-short-period super-Earth with an extremely high density and an outer companion
    We present the discovery and characterization of a new multi-planetary system around the Sun-like star K2-360 (EPIC 201595106). K2-360 was first identified in K2 photometry as the host of an ultra-short-period (USP) planet candidate with a period of 0.88 d. We obtained follow-up transit photometry, confirming the star as the host of the signal

    CEERS Key Paper. IX. Identifying Galaxy Mergers in CEERS NIRCam Images Using Random Forests and Convolutional Neural Networks
    A crucial yet challenging task in galaxy evolution studies is the identification of distant merging galaxies, a task that suffers from a variety of issues ranging from telescope sensitivities and limitations to the inherently chaotic morphologies of young galaxies. In this paper, we use random forests and convolutional neural networks to identify

    Distance estimation of gamma-ray-emitting BL Lac objects from imaging observations
    Aims. The direct redshift determination of BL Lac objects is highly challenging as the emission in the optical and near-infrared bands is largely dominated by the non-thermal emission from the relativistic jet, which points very close to our line of sight. Therefore, the optical spectra of BL Lac objects often show no spectral lines from the host
