On signed graphs with at most two eigenvalues unequal to
Willem H. Haemers, Hatice Topcu
We present the first steps towards the determination of the signed graphs for which the adjacency matrix has all but at most two eigenvalues equal to 1 or -1. Here we deal with the…
Resolved Neutral Outflow from a Lensed Dusty Star Forming Galaxy at z=2.09
Kirsty M. Butler, Paul P. van der Werf, Matus Rybak +9
We report the detection of a massive neutral gas outflow in the z=2.09 gravitationally lensed Dusty Star-Forming Galaxy HATLASJ085358.9+015537 (G09v1.40), seen in absorption with t…
The "Second Solar Spectrum" of the post-AGB binary 89 Herculis
Manuele Gangi, Francesco Leone
We report a spectropolarimetric study of the post-AGB binary system 89 Herculis, based on data acquired with the high-resolution Catania Astrophysical Observatory Spectropolarimete…
Spectro-Polarimetric Analysis of an Umbral Filament
S. L. Guglielmino, P. Romano, B. Ruiz Cobo +2
High-resolution observations of the solar photosphere have recently revealed the presence of elongated filamentary bright structures inside sunspot umbrae. These features, which ha…
Automatic Detection of Fake News

The proliferation of misleading information in everyday access media outlets such as social media feeds, news blogs, and online newspapers have made it challenging to identify trus…
Forest fires on with ignition only at 0
Stanislav Volkov
We consider a version of the forest fire model on graph , where each vertex of a graph becomes occupied with rate one. A fixed vertex is hit by lightning with the same rat…
