We analyse the globular cluster (GC) systems of a sample of 15 massive, compact early-type galaxies (ETGs), 13 of which have already been identified as good...

We test the modified Newtonian dynamics (MOND) theory with the velocity dispersion profiles of Galactic globular clusters populating the outermost region of the...

Studying the content and distribution of molecular gas (H $_{2}$) provides key insights into how feedback from active galactic nuclei (AGNs) and star formation...

A significant fraction of an exoplanet transit model evaluation time is spent calculating projected distances between the planet and its host star. This is a...

Many areas of astrophysics, including exoplanetary studies, rely on precise and accurate stellar parameters. This demands that uncertainties on these parameters...

As the fields of stellar and exoplanetary study grow and revolutionary new detection instruments are created, it is imperative that a homogeneous, precise...

We present a reassessment of the radial abundance gradients of He, C, N, O, Ne, S, Cl, and Ar in the Milky Way using the deep optical spectra of 42 H II regions...

We present the results of our search near the end of the Reionization Epoch for faint galaxies. This has been done using very deep OSIRIS images obtained at the...

By assuming the existence of a quasi-steady state of binary orbits of collapsed objects, a simple theory, relating the initial input distribution of semimajor...
