A method is defined for identifying late-T and Y dwarfs in WISE down to low values of signal-to-noise. This requires a WISE detection only in the W2-band and...

PublicationA deeper look at the dust attenuation law of star-forming galaxies at high redshift
A diverse range of dust attenuation laws is found in star-forming galaxies. In particular, Tress et al. (2018) studied the SHARDS survey to constrain the NUV...

PublicationA detailed look at the stellar populations in green valley galaxies
The green valley (GV) represents an important transitional state from actively star-forming galaxies to passively evolving systems. Its traditional definition...

PublicationA detailed study of the barium central star of the planetary nebula Abell 70
We present a detailed study of the barium star at the heart of the planetary nebula Abell 70. Time-series photometry obtained over a period of more than 10 yr...

PublicationA detailed two-dimensional stellar population study of M32
We present integral field spectroscopy of the 9×12arcsec2 circumnuclear region of M32 obtained with the 2D_FIS fibre optics spectrographs installed at the 4.2-m...

PublicationA detection of the donor star of Aquila X-1 during its 2004 outburst?
Phase-resolved high-resolution optical spectroscopy has revealed narrow NIII and HeII emission lines from the soft X-ray transient Aquila X-1 during its 2004...

PublicationA determination of the space density and birth rate of hydrogen-line (DA) white dwarfs in the Galactic plane, based on the UVEX survey
We present a determination of the average space density and birth rate of hydrogen-line (DA) white dwarfs within a radius of 1 kpc around the Sun, based on an...

PublicationA devil in the detail: parameter cross-talk from the solar cycle and estimation of solar p-mode frequencies
Frequencies, powers and damping rates of the solar p modes are all observed to vary over the 11-yr solar activity cycle. Here, we show that simultaneous...

PublicationA distance of 13 Mpc resolves the claimed anomalies of the galaxy lacking dark matter
The claimed detection of a diffuse galaxy lacking dark matter represents a possible challenge to our understanding of the properties of these galaxies and...
