A near/mid infrared search for ultra-bright submillimetre galaxies: Searching for Cosmic Eyelash Analogues
We present results from a near-/mid-IR search for submillimetre galaxies over a region of 6230 deg2 of the southern sky. We used a cross-correlation of the...
A New Chemo-evolutionary Population Synthesis Model for Early-Type Galaxies. I. Theoretical Basis
We have developed a new stellar population synthesis model designed to study early-type galaxies. It provides optical and near-infrared colors, and line indices...
A New Chemo-evolutionary Population Synthesis Model for Early-Type Galaxies. II. Observations and Results
We present the results of applying a new chemo-evolutionary stellar population model, developed in a previous paper, to new high-quality observational data of...
A new discovery space opened by eROSITA. Ionised AGN outflows from X-ray selected samples
Context. In the context of an evolutionary model, the outflow phase of an active galactic nucleus (AGN) occurs at the peak of its activity, once the central...
A New Einstein Cross Gravitational Lens of a Lyman-break Galaxy
We report the study of an “Einstein Cross” configuration first identified in a set of HST images by Cerny et al. Deep spectroscopic observations obtained at the...
A new method for age-dating the formation of bars in disc galaxies. The TIMER view on NGC1433's old bar and the inside-out growth of its nuclear disc
The epoch in which galactic discs settle is a major benchmark for testing models of galaxy formation and evolution but remains largely unknown. Once discs...
A New Method of Estimating the Mass-to-Light Ratio of the Ursa Minor Dwarf Spheroidal Galaxy
Dwarf satellite galaxies undergo strong tidal forces produced by the main galaxy potential. These forces disturb the satellite and produce asymmetries in its...
