If dwarf galaxies are primeval objects in the universe, as hierarchical galaxy formation scenarios predict, they should show traces of their old stellar...

We have obtained deep HST imaging of two candidate dwarf systems in the nearby M81 Group, DDO 44 and UGC 4998. Both are isolated, low surface brightness systems...

Dwarf-galaxy sized dark matter halos may be detectable when a bright background source is gravitationally lensed on scales of milliarcseconds. Such effects can...

We present Atacama Large Millimeter/submillimeter Array observations of the 870 μm continuum and CO(4-3) line emission in the core of the galaxy cluster Cl...

We study the distribution of cold molecular gas in the circumunuclear disks (CND; r ≤ 200 pc) of a sample of 64 nearby (D L = 7 ‑ 45 Mpc) disk galaxies –...

We present here a thorough photometric analysis of double-barred galaxies, consisting of (i) two-dimensional photometric decompositions including a bulge, inner...

The intrinsic photometric properties of inner and outer stellar bars within 17 double-barred galaxies are thoroughly studied through a photometric analysis...

We study the physical and kinematic properties of the narrow-line region (NLR) of the nearest obscured quasar MRK 477 (z = 0.037), using optical and near...

Using data from the Near-Infrared S0 Survey of nearby, early-type galaxies, we examine the distribution of bar strengths in S0 galaxies as compared to S0/a and...
