    A refined sub-grid model for black hole accretion and AGN feedback in large cosmological simulations
    In large-scale cosmological hydrodynamic simulations simplified sub-grid models for gas accretion on to black holes and AGN feedback are commonly used. Such...

    A remarkable recurrent nova in M31: Discovery and optical/UV observations of the predicted 2014 eruption
    The Andromeda Galaxy recurrent nova M31N 2008-12a had been caught in eruption eight times. The inter-eruption period of M31N 2008-12a is ~1 yr, making it the...

    A remarkably large depleted core in the Abell 2029 BCG IC 1101
    We report the discovery of an extremely large (Rb ∼2.77 arcsec ≈ 4.2 kpc) core in the brightest cluster galaxy, IC 1101, of the rich galaxy cluster Abell 2029...

    A Robust Age Indicator for Old Stellar Populations
    We derive new spectral Hγ index definitions that are robust age indicators for old and relatively old stellar populations and therefore have great potential for...

    A sample of dust attenuation laws for Dark Energy Survey supernova host galaxies
    Context. Type Ia supernovae (SNe Ia) are useful distance indicators in cosmology, provided their luminosity is standardized by applying empirical corrections...

    A SAURON look at galaxy bulges
    Kinematic and population studies show that bulges are generally rotationally flattened systems similar to low-luminosity ellipticals. However, observations with...

    A SCUBA-2 selected Herschel-SPIRE dropout and the nature of this population
    Dusty star-forming galaxies (DSFGs) detected at z > 4 provide important examples of the first generations of massive galaxies. However, few examples with...

    A search for planetary nebulae in M33
    We searched for planetary nebulae (PNe) in the nearby spiral galaxy M33 using the Wide Field Camera at the 2.54 m Isaac Newton Telescope of La Palma (Spain)...
