Rotation curves and velocity dispersion profiles are presented for both the stellar and gaseous components along five different position angles (PA =5°, 50°, 95...

Aims: NGC 6240 is a well-studied nearby galaxy system in the process of merging. Based on optical, X-ray, and radio observations, it is thought to harbor two...

We construct Schwarzschild orbit-based models of NGC 7457, known as a peculiar low-mass lenticular galaxy. Our best-fitting model successfully retrieves most of...

As early as 10 Gyr ago, galaxies with more than 1011 M ☉ of stars already existed. While most of these massive galaxies must have subsequently transformed...

We examine the spectrum in the vicinity of the NH3360 index of Davidge & Clark, which was defined to measure the NH absorption around 3360 Å and shows almost no...

We present deep, high angular-resolution HST NICMOS imaging in the Hubble Deep Field South (HDF-S), focusing on a subset of 14 distant red galaxies (DRGs) at z...

We report 0.9-1.4 mu m spectroscopic observations of NGC 1068 collected during the commissioning phase of the near infrared camera spectrometer (NICS) of the...

We have simulated the formation of a galaxy cluster in a Λ cold dark matter universe using 13 different codes modelling only gravity and non-radiative...

Building on the initial results of the nIFTy simulated galaxy cluster comparison, we compare and contrast the impact of baryonic physics with a single massive...
