PublicaciónThe Tilt of the Fundamental Plane: Three-Quarters Structural Nonhomology, One-Quarter Stellar Population
The variation of the mass-to-light M/L ratios of early-type galaxies as a function of their luminosities L is investigated. It is shown that the tilt β=0.27 (in...

PublicaciónThe tilted old Galactic disc and the position of the Sun
With the use of data from COBE, IRAS and the Two-micron Galactic Survey (TMGS), we examine the effect on star counts and surface brightness maps of the position...

PublicaciónThe 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...

PublicaciónThe 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...
