We use IFS data of four galaxies from the TIMER survey to explore the kinematics measured in different spectral regions that are sensitive to distinct stellar populations. We derive the velocity and velocity dispersion of both a young and an old stellar population and several stellar parameters. We report a correlation of the mean luminosity

We present a comparison of the spin parameter λ R, measured in a region dominated by the galaxy disc, between 20 pairs of nearby (0.005 < z < 0.03) seemingly isolated twin galaxies differing in nuclear activity. We find that 80-82% of the active galaxies show higher values of λ R than their corresponding non-active twin(s), indicating larger

We present an independent discovery and detailed characterization of K2-280 b, a transiting low density warm sub-Saturn in a 19.9-d moderately eccentric orbit (e = $0.35_{-0.04}^{+0.05}$ ) from K2 campaign 7. A joint analysis of high precision HARPS, HARPS-N, and FIES radial velocity measurements and K2 photometric data indicates that K2-280 b has

Presenting the first detection of a peanut structure in the inner bar of a double-barred system! Peanuts are formed after the buckling of stellar bars. Having peanuts in inner bars suggests they are long-lived structures, analogous to regular bars... thus solving the long debate about the nature of double bars.

The High Optical Resolution Spectrograph (HORus) has been available on the 10-m GTC telescope since early 2019. Based largely on optical elements reused from UES, in operation on the 4-m WHT in the 90s, HORuS provides a resolving power of 25,000 with nearly complete coverage in the range 380-700 nm. This instrument gives a signal-to-noise ratio at

A brief narrative on how the effective radius and isophotal diameters were accepted as galaxy size measures is presented. Evidence suggests that these parameters were defined only based on observational premises, independent of any astrophysical theories. An alternative, new physically motivated size definition based on the expected gas density
