Description
Galaxy formation by gravitational instability implies the presence of temperature fluctuations in the cosmic microwave background. New observations at 10.45 and 14.9 GHz from the Observatorio del Teide in Tenerife on angular scales of several degrees reveal structure of galactic origin at the lower frequency, while at the upper frequency the magnitude of fluctuations of cosmological origin must be less than 1.8 x 10 exp -5 on a scale of 5 deg. This strongly constrains models of galaxy formation, and is compatible with the recently announced discovery by the COBE satellite of fluctuations on larger angular scales.

    Constraining the TeV gamma-ray emission of SN 2024bch, a possible type IIn-L from a red supergiant progenitor: Multiwavelength observations and analysis of the progenitor
    We present very high-energy optical photometry and spectroscopic observations of SN 2024bch in the nearby galaxy NGC 3206 (∼20 Mpc). We used gamma-ray observations performed with the first Large-Sized Telescope (LST-1) of the Cherenkov Telescope Array Observatory (CTAO) and optical observations with the Liverpool Telescope (LT) combined with data

    Context. Over the past 15 years, studies of quasars in the far-infrared (FIR) have reported host luminosities ranging from 10 12 to 10 14 L ⊙. These luminosities, often derived from Herschel/SPIRE photometry, suggest star formation rates (SFRs) of up to several thousand M ⊙ yr ‑1, positioning them among the most luminous starburst galaxies in the

    Transit timing variations in HIP 41378: CHEOPS and TESS confirm a non-transiting sixth planet in the system
    In multiple-planet systems, gravitational interactions of exoplanets could lead to transit timing variations (TTVs), whose amplitude becomes significantly enhanced when planets are in or near mean-motion resonances (MMRs), making them more easily detectable. In cases where both TTVs and radial velocity (RV) measurements are available, combined
