Origin and Evolution of Large-scale Magnetic Fields

, 2015
Magnetic elds are ubiquitous at all scales in the Universe and have been observed in galaxies and clusters of galaxies via observations of di use radio emission and Faraday Rotation Measures.

Active galactic nuclei and their role in galaxy evolution: The infrared perspective

, 2014
The remarkable progress made in infrared (IR) astronomical instruments over the last 10-15 years has radically changed our vision of the extragalactic IR sky, and overall understanding of galaxy evolution.

The Arp Ring: Galactic or extragalactic?

, 1987
The Arp Ring is a faint, loop-like structure around the northern end of M81 which becomes apparent only on deep optical photographs of the galaxy. The nature of the Ring and its proximity to M81 are uncertain.

Empirical sigma - d relations and main galactic radio loops

, 2002
This paper represents a review of the empirical Galactic and extragalactic sigma - D relations (relations between the surface brightness sigma and the diameter D) for supernova remnants (SNRs), with checking the connection of the main Galactic radio ...

VISTA Science Verification — The Galactic and Extragalactic Mini-surveys

, 2010
The Visible and Infrared Survey Telescope for Astronomy (VISTA) will be mostly dedicated to the execution of ESO public surveys, requiring large amounts of service observing time. VISTA Science Verification (SV) thus differs from that usually implemented

The Faint Radio Sky: Radio Astronomy Becomes Mainstream

, 2016
Radio astronomy has changed. After years of studying rare, mostly non-thermal sources, i.e. radio quasars and radio galaxies, it is now reaching such faint flux densities that it detects mainly star-forming galaxies and the more common radio-quiet active

Secondary evolution of galaxies investigated by N-body simulations

, 2008
In the ΛCDM cosmology, merging is one of the most important physical processes that drives the formation and evolution of galaxies. In the present work, we use N-body techniques to investigate some of currently open issues related to the formation and ...

Introducing the DREAMS Project: DaRk mattEr and Astrophysics with Machine Learning and Simulations

The Astrophysical Journal
We introduce the DaRk mattEr and Astrophysics with Machine learning and Simulations (DREAMS) project, an innovative approach to understanding the astrophysical implications of alternative dark matter (DM) models and their effects on galaxy formation and ...
