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...

PublicaciónAn Investigation into the Prominence of Spiral Galaxy Bulges
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...

PublicaciónAn Optical Study of a Sample of Spiral Galaxies
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...

PublicaciónAn unusual transient in the extremely metal-poor Galaxy SDSS J094332.35+332657.6 (Leoncino Dwarf)
We have serendipitously discovered that Leoncino Dwarf, an ultrafaint, low-metallicity record-holder dwarf galaxy, may have hosted a transient source, and...

PublicaciónAnalysis of the galaxy size versus stellar mass relation
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...

PublicaciónAre ultra-diffuse galaxies Milky Way-sized?
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...

PublicaciónAsteroid pairs: A complex picture
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...

PublicaciónAsteroseismology of iota Draconis and Discovery of an Additional Long-period Companion
Giant stars as known exoplanet hosts are relatively rare due to the potential challenges in acquiring precision radial velocities and the small predicted...

PublicaciónAsymptotic giant branch stars in NGC 6822: Probes of star formation history
About 500 asymptotic giant branch (AGB) stars have been resolved and photometrically measured in the Local Group (LG) dwarf irregular galaxy NGC 6822. They draw...
