Context. The transiting exoplanetary system WASP-174 was reported to be composed by a main-sequence F star (V = 11.8 mag) and a giant planet, WASP-174b (orbital...
The HIPASS catalogue - III. Optical counterparts and isolated dark galaxies
We present the largest catalogue to date of optical counterparts for HI radio-selected galaxies, HOPCAT. Of the 4315 HI radio-detected sources from the HI...
Aims: Over its lifetime and despite not being a survey telescope, the Hubble Space Telescope (HST) has obtained multi-epoch observations by multiple, diverse...
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. XV. The Dynamical Clock: Reading Cluster Dynamical Evolution from the Segregation Level of Blue Straggler Stars
The parameter A +, defined as the area enclosed between the cumulative radial distribution of blue straggler stars (BSSs) and that of a reference population, is...
The Hydrangea simulations: galaxy formation in and around massive clusters
We introduce the Hydrangea simulations, a suite of 24 cosmological hydrodynamic zoom-in simulations of massive galaxy clusters (M200c = 1014-1015.4 M⊙) with...
The impact of baryons on the spins and shapes of dark matter haloes
We use numerical simulations to investigate how the statistical properties of dark matter (DM) haloes are affected by the baryonic processes associated with...
The impact of filaments on dwarf galaxy properties in the Auriga simulations
With a hydrodynamical simulation using a simple galaxy formation model without taking into account feedback, our previous work has shown that dense and massive...
The Impact of Gaia and LSST on Binaries and Exoplanets
Two upcoming large scale surveys, the ESA Gaia and LSST projects, will bring a new era in astronomy. The number of binary systems that will be observed and...
