Description
NGC 5982 is known to be one of those elliptical galaxies that have peculiar kinematics in their centres. In this paper, optical spectroscopic observations are presented, which show that a specific feature is present in the velocity field of NGC 5982. This suggests that the kinematical behaviour is the result of projection effects in a dynamically smooth triaxial elliptical galaxy, and that it is not due to a dynamically distinct, central mass component. Nevertheless, we suggest that it may be related to a merger event.

    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
