We investigate the formation of the satellite galaxy population of a Milky Way-mass halo in a very highly resolved magnetohydrodynamic cosmological zoom-in...

We have studied here for the first time the use of the log(H 0/[N 0]), log (H 0/[S 0]) diagnostic diagram for determining the metallicities and ionization...

Lyman alpha emitters (LAEs) and Lyman break galaxies (LBGs) represent the most common groups of star-forming galaxies at high z, and the differences between...

We examine the stellar velocity dispersions (σ) of a sample of 48 galaxies, 35 of which are spirals, from the Palomar nearby galaxy survey. It is known that for...

We use a sample of 706 galaxies, selected as [O II]λ3727 ([O II]) emitters in the Survey for High-z Absorption Red and Dead Sources (SHARDS) on the CANDELS...

We present non-LTE analyses of four M33 early B supergiant stars and five Galactic counterparts. This is the first time that B supergiants beyond the Magellanic...

Context. Diffuse interstellar bands (DIBs) are faint spectral absorption features of unknown origin. Research on DIBs beyond the Local Group is very limited and...

Context: .Compact groups are associations of a few galaxies in which the environment plays an important role in galaxy evolution. The low group velocity...

We present the surface photometry and stellar kinematics of NGC 2950, which is a nearby and undisturbed SB0 galaxy hosting two nested stellar bars. We use the...
