Astrometry and photometry of 7 open clusters
We present a study of seven southern open clusters based on UBVRI CCD photometry (Johnsons-Cousins system) and Gaia DR2 data. Dias4, Dias6, and four other clusters had UBVRI... -
Parallaxes of Southern Extremely Cool objects
We present new results from the Parallaxes of Southern Extremely Cool dwarfs program to measure parallaxes, proper motions and multiepoch photometry of L and early T dwarfs. The... -
JINGLE, Survey overview and first results
JINGLE is a new JCMT legacy survey designed to systematically study the cold interstellar medium of galaxies in the local Universe. As part of the survey we perform 850{mu}m... -
Chemo-kinematics from MARVELS
Combining stellar atmospheric parameters, such as effective temperature, surface gravity, and metallicity, with barycentric radial velocity data provides insight into the... -
Gaia Nuclear Transient (GNT) cand.
The high spatial resolution and precise astrometry and photometry of the Gaia mission should make it particularly apt at discovering and resolving transients occurring in, or... -
On the nature of small galaxy systems
We aim at defining homogeneous selection criteria of small galaxy systems in order to build catalogues suitable to compare main properties of pairs, triplets, and groups with... -
2MASS bright galaxies HI ZoA survey
To complement the 2MASS Redshift Survey (2MRS) and the 2MASS Tully-Fisher survey (2MTF) a search for 21cm HI line emission of 2MASS bright galaxy candidates has been pursued... -
Gaia DR2 RR Lyrae stars as standard candles
We present results from the analysis of 401 RR Lyrae stars (RRLs) belonging to the field of the Milky Way (MW). For a fraction of them multiband (V, Ks, W1) photometry, metal... -
ShaSS filamentary network connecting clusters
We have mapped the structure and connectivity of the Shapley supercluster core and its surroundings as traced by its member galaxies. To achieve this, we have carried out a new... -
Variable stars in the SMCNOD
We present a study of a recently discovered stellar overdensity near the northern edge of the Small Magellanic Cloud (SMCNOD). We exploited variable stars from the fourth... -
Multiwavelength cross-correlations in blazars
Blazars are known for their energetic multiwavelength flares from radio wavelengths to high-energy {gamma}-rays. In this work, we study radio, optical, and {gamma}-ray light... -
(non-)existence of five sparse open clusters
Sparse open clusters can be found at high galactic latitudes where loosely populated clusters are more easily detected against the lower stellar background. Because most star... -
SDSS distant sample of halo wide binaries
Samples of reliably identified halo wide binaries are scarce. If reasonably free from selection effects and with a small degree of contamination by chance alignments, these wide... -
Extended main sequence turnoff in open cluster
We present an analysis of the relatively low mass (~2400M_{sun}_), ~800Myr, Galactic open cluster, NGC 2818, using Gaia DR2 results combined with VLT/FLAMES spectroscopy. Using... -
AGN luminosity fraction in merging galaxies
Galaxy mergers are key events in galaxy evolution, often causing massive starbursts and fueling active galactic nuclei (AGNs). In these highly dynamic systems, it is not yet... -
CORNISH project IV. Radio-selected galactic PN
We present a new radio-selected sample of PNe from the CORNISH survey. We find 90 new PNe, of which 12 are newly discovered and 78 are newly classified as PN. A further 47... -
Extended emission-line regions of obscured AGN
Narrow-line regions excited by active galactic nuclei (AGNs) are important for studying AGN photoionization and feedback. Their strong [OIII] lines can be detected with... -
Quantifying maximum discs in galaxies
Maximum disc decompositions of rotation curves place a dynamical upper limit to the mass attributable to stars in galaxies. The precise definition of this term, however, can be... -
The {gamma}-ray spectrum of 1BIGB sources
We present the 1-100GeV spectral energy distribution (SED) for a population of 148 high-synchrotron-peaked (HSP) blazars recently detected with Fermi-LAT as part of the First... -
Star formation on LV dwarf galaxies
Spatially resolved HI studies of dwarf galaxies have provided a wealth of precision data. However these high-quality, resolved observations are only possible for handful of...
