We present an analysis of the integrated Hα emission line profiles for the H SHAPE Ii region population of the spiral galaxies NGC 1530, NGC 6951 and NGC 3359...

We investigate the internal kinematics of the young star-forming region NGC 346 in the Small Magellanic Cloud (SMC). We used two epochs of deep F555W and F814W...

Comparison of recent spectra by V. Motta et al. (V. Motta et al.: Astrophys. J. 574, 719 725) of two images of a distant gravitationally lensed quasar (z = 1.38...

We present a new determination of the interstellar 12CH+/13CH+ ratio in the solar neighbourhood, based on high spectral resolution CCD observations of the CH+...

We observed the λ 4232 Å CH+ interstellar line in the direction of the Sco OB 1 association (d ≃ 2 kpc) with the aim of detecting variations of the 12C/13C...

Submillimeter galaxies (SMGs) at z≳ 1 are luminous in the far-infrared, and have star formation rates, SFR, of hundreds to thousands of solar masses per year...

We have studied the kinematics and spatial distribution of the interstellar gas in the sky region 110°

We characterise the basic far-IR properties and the gas mass fraction of massive (⟨log(M */M ⊙)⟩ ≈ 11.0) quiescent galaxies (QGs) and explore how these evolve...

By using deep observations of clusters of galaxies, it has been recently found that the projected stellar mass density closely follows the projected total (dark...
