PublicationThe TOI-763 system: sub-Neptunes orbiting a Sun-like star
We report the discovery of a planetary system orbiting TOI-763(aka CD-39 7945), a V = 10.2, high proper motion G-type dwarf star that was photometrically...

PublicationThe trace of a substantial assembly of massive E-S0 galaxies at 0.8 < z < 1.5 in galaxy number counts
K-band galaxy number counts (GNCs) exhibit a slope change at K ˜ 17.5 mag not present in optical bands. To unveil the nature of this feature, we have derived...

PublicationThe TRAPUM L-band survey for pulsars in Fermi-LAT gamma-ray sources
More than 100 millisecond pulsars (MSPs) have been discovered in radio observations of gamma-ray sources detected by the Fermi Large Area Telescope (LAT), but...

PublicationThe triggering mechanism and properties of ionized outflows in the nearest obscured quasars
We have identified ionized outflows in the narrow-line region of all but one Sloan Digital Sky Survey type 2 quasars (QSO2) at z≲0.1 (20/21, detection rate 95...

PublicationThe triple-shell structure and collimated outflows of the planetary nebula NGC 6891
Narrow-band Hα and [Nii] images and high-dispersion spatially resolved echelle spectroscopy of the planetary nebula NGC 6891 are presented. These observations...

PublicationThe Tully-Fisher relation and the Bosma effect
We show that the rotation curves of 16 nearby disc galaxies in the THINGS sample and the Milky Way can be described by the Navarro-Frenk-White halo model and by...

PublicationThe UK Infrared Telescope M 33 monitoring project - V. The star formation history across the galactic disc
We have conducted a near-infrared monitoring campaign at the UK Infrared Telescope of the Local Group spiral galaxy M 33 (Triangulum). On the basis of their...

PublicationThe UKIRT Infrared Deep Sky Survey (UKIDSS)
We describe the goals, design, implementation, and initial progress of the UKIRT Infrared Deep Sky Survey (UKIDSS), a seven-year sky survey which began in 2005...
