Descripción
The serendipitous discovery of a new type I Seyfert galaxy, IRAS 09149-6206, found during a search for planetary nebulae using the IRAS Point Source Catalog is reported. The optical spectrum of this galaxy shows very strong broad Balmer and Fe II emission, indicating the existence of large optical depths, while the emission spectrum from the narrow line region is relatively weak, with only the high excitation lines present. The object presents extended forbidden O III emission, and from the rotation curve, a mass of 8 x 10th the 9th solar masses is calculated within a radius of 3 kpc. It is suggested that the activity could have been triggered by interaction with a close faint companion.

    Beyond the Nyquist frequency: Asteroseismic catalog of undersampled Kepler late subgiants and early red giants
    Subgiants and early red giants are crucial for studying the first dredge-up, a key evolutionary phase in which the convective envelope deepens, mixing previously interior-processed material and bringing it to the surface. Yet, very few have been seismically characterized with Kepler because their oscillation frequencies are close to the 30 minute

    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
