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 class of dark matter-free dwarf galaxies?: I. Clues from FCC 224, NGC 1052-DF2, and NGC 1052-DF4
Context. The discovery of quiescent, dark matter (DM)-deficient ultra-diffuse galaxies (UDGs) with overluminous globular clusters (GCs) has challenged galaxy...
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...
