The WISE and VLASS-SE images of J2335-0004. The right panel is the VLASS-SE image. The FWHM and centroid derived from the VLASS-SE image are blue ellipses and dots in all five panels. The four left panels are W1, W2, W3, and W4 band images of the source. The green contours represent 10𝜎, 50𝜎 and 100𝜎 of the noise levels in WISE W1 and W2 images, 3𝜎 and 6𝜎 in W3 and W4 images, and −1𝜎, 10𝜎 and 80𝜎 in the VLASS-SE image. The candidate star’s location is shown as the red stars in all the panels. -- astro-ph.GA

High-resolution Imaging Of The Radio Source Associated With Project Hephaistos Dyson Sphere Candidate G

by Keith CowingJanuary 11, 2025January 11, 2025

We present high-resolution e-MERLIN and EVN (e-VLBI) observations of a radio source associated with Dyson Sphere candidate G, identified as part of Project Hephaistos.

The offset positions of the radio sources associated with DS candidates A, B and G. Each field is 15 x 15 arcseconds in extent. The Gaia coordinates of the DS candidates define the centre of each field. -- astro-ph.SR

Background Contamination of the Project Hephaistos Dyson Spheres Candidates

by Keith CowingMay 27, 2024

Project Hephaistos recently identified seven M-dwarfs as possible Dyson Spheres (DS) candidates. We have cross-matched three of these candidates (A, B \& G) with radio sources detected in various all-sky […]
