We present the results of hydrodynamical model calculations of the barred galaxy NGC 5850 and compare to HI observations. The models assume a mass distribution...

From a diameter-limited sample of 86 low-inclination (face-on) spiral galaxies, the bulge-to-disk size and luminosity ratios and other quantitative measurements...

We present the first results of an observational project aimed at producing a database of nearby face-on spiral galaxies in the optical. The project is being...

We have serendipitously discovered that Leoncino Dwarf, an ultrafaint, low-metallicity record-holder dwarf galaxy, may have hosted a transient source, and...

The scatter in the galaxy size versus stellar mass (M ⋆) relation gets largely reduced when, rather than the half-mass radius R e, the size at a fixed surface...

Context. The halos of low-mass galaxies may allow us to constrain the nature of dark matter (DM), but the kinematic measurements needed to diagnose the required...

Now almost 70 years since its introduction, the effective or half-light radius has become a very popular choice for characterising galaxy size. However, the...

We studied a sample of 93 asteroid pairs, i.e., pairs of genetically related asteroids that are on highly similar heliocentric orbits. We estimated times...

Giant stars as known exoplanet hosts are relatively rare due to the potential challenges in acquiring precision radial velocities and the small predicted...
