First Very Long Baseline Interferometry Fringe Detection at 690GHz
Ming-Tang Chen, Geoffrey B. Crew, Dan Bintley +42
We report the first very long baseline interferometry (VLBI) experiment conducted in the 690 GHz atmospheric window. On 2024 November 21, observations with the Atacama Large Millim…
Virgo Filaments VII: MeerKAT HI-imaging of the VirgoIII filament
M. Ramatsoku, G. Nagaraj, P. Jablonka +11
We present MeerKAT HI observations of galaxies in the nearby Virgo III filament. At a median distance of Mpc, the filament extends over Mpc across deg…
High performance Stingray
Eleonora Veronica Lai, Matteo Bachetti, Maura Pilia +4
X-ray astrophysical objects show variability on a wide range of timescales, i.e. from fractions of second to years. The open-source Python library stingray is able to perform time…
Constraints on the magnetic field in the hadronic scenario for the origin of the radio halo in the A1795 galaxy cluster
P. Marchegiani, V. Vacca, F. Loi +2
The radio halo in the cool-core galaxy cluster, A1795, has recently been proposed to be of hadronic origin, because it extends on megaparsec scales, where no turbulence is expected…
Quasi-automatic software support for Gaia ground based optical tracking
S. Bouquillon, C. Barache, T. Carlucci +6
The ESA Gaia satellite mission will create a catalog of 1 billion stars with unprecedented astrometric precision. To achieve its aim in terms of astrometric precision, a ground bas…
GBOT: ground based optical tracking of the Gaia satellite
Martin Altmann, Sebastien Bouquillon, Francois Taris +6
Gaia, the 1 billion star, high precision, astrometric satellite will revolutionise our understanding in many areas of astronomy ranging from bodies in our Solar System to the forma…
