New Spatially Resolved Observations of Betelgeuse from the VLA and ALMA: Evidence for Atmospheric Perturbations from a Close Companion
L. D. Matthews, A. K. Dupree, A. M. S. Richards +1
We present new spatially resolved observations of the red supergiant Betelgeuse ( Orionis) at seven frequencies: 22 GHz (1.36cm); 44 GHz (6.8mm); 107 GHz (2.8mm); 136 G…
Euclid: Calibrating distances from surface brightness fluctuations with Early Release Observations of the Fornax cluster
R. Habas, M. Cantiello, G. Riccio +169
Surface brightness fluctuations (SBF), the pixel-to-pixel variations in flux that arise from the statistical distribution of stars in galaxy images, provide a powerful tool to meas…
Investigating anomalous microwave emission near G107.2+5.20 in Ku-band with the Green Bank Telescope
Jordan E. Shroyer, Bradley R. Johnson, Dillon J. Bass +6
The authors use Green Bank Telescope Ku‑band observations to map the region around G107.2+5.20, constraining the low‑frequency side of the anomalous microwave emission spectrum and…
Euclid Quick Data Release (Q1). The average far-infrared properties of Euclid-selected star-forming galaxies
Euclid Collaboration, R. Hill, A. Abghari +302
The first Euclid Quick Data Release contains millions of galaxies with excellent optical and near-infrared (IR) coverage. To complement this dataset, we investigate the average far…
Euclid Quick Data Release (Q1). Searching for radio-selected \Euclid-dark galaxies in the EDF-N
Euclid Collaboration, M. Giulietti, I. Prandoni +308
We present and investigate the properties of a sample of radio-selected, Euclid-dark galaxies, identified from LOFAR HBA observations at 144 MHz within the Euclid Deep Field-North…
Euclid: The convective-transition gap of 47 Tuc
M. Libralato, M. Griggio, R. Gerasimov +140
We report the first detection of the `convective-transition gap' (also known as `M-dwarf gap') in the globular cluster 47 Tuc (NGC 104) thanks to Euclid data. This feature, linked…
