First release of Apertif imaging survey data
Elizabeth A. K. Adams, B. Adebahr, W. J. G. de Blok +56
(Abridged) Apertif is a phased-array feed system for WSRT, providing forty instantaneous beams over 300 MHz of bandwidth. A dedicated survey program started on 1 July 2019, with th…
The LOFAR Two-metre Sky Survey -- V. Second data release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +103
In this data release from the LOFAR Two-metre Sky Survey (LoTSS) we present 120-168MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at ap…
Radio data archives round table
K. A. Lutz, J. Dempsey, Y. G. Grange +3
With SKA precursor and pathfinder operations in full swing, radio and (sub-)mm astronomy is entering the era of super big data. The big questions is how to make (sub-)mm and radio…
Satellite Constellation Internet Affordability and Need
Meredith L. Rawls, Heidi B. Thiemann, Victor Chemin +3
Large satellite constellations in low-Earth orbit seek to be the infrastructure for global broadband Internet and other telecommunication needs. We briefly review the impacts of sa…
Operations in the era of large distributed telescopes
Yan Guillaume Grange, Kevin Vinsen, Juan Carlos Guzman +4
The previous generation of astronomical instruments tended to consist of single receivers in the focal point of one or more physical reflectors. Because of this, most astronomical…
Estimating turbulent velocities in the elliptical galaxies NGC 5044 and NGC 5813
J. de Plaa, I. Zhuravleva, N. Werner +5
The interstellar and intra-cluster medium in giant elliptical galaxies and clusters of galaxies is often assumed to be in hydrostatic equilibrium. Numerical simulations, however, s…
The metal contents of two groups of galaxies
Y. G. Grange, J. de Plaa, J. S. Kaastra +4
The hot gas in clusters and groups of galaxies is continuously being enriched with metals from supernovae and stars. It is well established that the enrichment of the gas with elem…
Cold fronts and multi-temperature structures in the core of Abell 2052
J. de Plaa, N. Werner, A. Simionescu +3
The physics of the coolest phases in the hot Intra-Cluster Medium (ICM) of clusters of galaxies is yet to be fully unveiled. X-ray cavities blown by the central Active Galactic Nuc…
X-ray spectral study of the hot gas in three Clusters of Galaxies
Y. G. Grange, E. Costantini, J. de Plaa +4
We study the physical properties of three clusters of galaxies, selected from a BeppoSAX Wide Field Camera (WFC) survey. These sources are identified as 1RXS J153934.7-833535, 1RXS…
