This paper represents a collective effort to provide an extensive electronic database useful for the interpretation of the spectra and evolution of galaxies. A...
A dearth of planetary transits in the direction of NGC 6940
We present results of our survey for planetary transits in the field of NGC 6940. We think nearly all of our observed stars are field stars. We have obtained...
A dearth of small particles in the transiting material around the white dwarf WD 1145+017
White dwarf WD 1145+017 is orbited by several clouds of dust, possibly emanating from actively disintegrating bodies. These dust clouds reveal themselves...
A dearth of young and bright massive stars in the Small Magellanic Cloud
Context. Massive star evolution at low metallicity is closely connected to many fields in high-redshift astrophysics, but is poorly understood so far. Because...
A decade of near-infrared variability in NGC4388: insights into the AGN structure
Variability studies have proven to be a powerful diagnostic tool for understanding the physics and properties of active galactic nuclei (AGNs). They provide...
A DECam view of the diffuse dwarf galaxy Crater II - Variable stars
Time series observations of a single dithered field centred on the diffuse dwarf satellite galaxy Crater II were obtained with the Dark Energy Camera (DECam) at...
A DECam view of the diffuse dwarf galaxy Crater II: the colour-magnitude diagram
We present a deep Blanco/DECam colour-magnitude diagram (CMD) for the large but very diffuse Milky Way satellite dwarf galaxy Crater II. The CMD shows only old...
A deep learning approach to infer galaxy cluster masses from Planck Compton-y parameter maps
Galaxy clusters are useful laboratories to investigate the evolution of the Universe, and accurate measurement of their total masses allows us to constrain...
