    New VR Magnification Ratios of QSO 0957+561
    We present VR magnification ratios of QSO 0957+561 that are inferred from the GLITP light curves of Q0957+561A and new frames taken with the 2.56 m Nordic...

    New young planetary nebulae in IPHAS
    Aims: We search for very small-diameter galactic planetary nebulae (PNe) representing the earliest phases of PN evolution. The IPHAS catalogue of Hα-emitting...

    Newly formed downflow lanes in exploding granules in the solar photosphere
    Context. Exploding granules have drawn renewed interest because of their interaction with the magnetic field (either emerging or already present). Especially...

    NGC 1436: the making of a lenticular galaxy in the Fornax Cluster
    We study the evolutionary path of the Fornax Cluster galaxy NGC 1436, which is known to be currently transitioning from a spiral into a lenticular morphology...

    NGC 1624-2: a slowly rotating, X-ray luminous Of?cp star with an extraordinarily strong magnetic field
    This paper presents a first observational investigation of the faint Of?p star NGC 1624-2, yielding important new constraints on its spectral and physical...
  • Publication
    NGC 2419: a large and extreme second generation in a currently undisturbed cluster
    We analyse complementary Hubble Space Telescope and Subaru data for the globular cluster NGC 2419. We make a detailed analysis of the horizontal branch (HB)...
  • Publication
    NGC 2579 and the carbon and oxygen abundance gradients beyond the solar circle
    We present deep echelle spectrophotometry of the Galactic H II region NGC 2579. The data have been taken with the Very Large Telescope Ultraviolet-Visual...

    NGC 4526 gas, high velocity clouds, and Galactic halo gas: the interstellar medium towards SN 1994D.
    We present spectroscopic observations of supernova 1994D in NGC 4526, an S0_3_ galaxy in the Virgo cluster 15Mpc distant. The datasets consist of the...

    NGC 4672: A new case of an early-type disk galaxy with an orthogonally decoupled core
    We report the case of the early-type disk galaxy NGC 4672 as a new example of a galaxy characterized by the orthogonal geometrical decoupling between bulge and...
