Wide-Mass-Scanning-Range Setup and Phase-Resolved Protocol for Axion Dark Matter Detection
A. Cottet, T. Kontos
We propose a paradigm for quantum enhanced axion dark matter search, which does not rely on power measurements. We propose to measure directly the axion amplitude and phase in an i…
Birds of a Feather Flock Together: Network-Based Detection of Coordinated Disinformation Campaigns on Telegram
Panteleimon Tsagkarakis, Emmanouil Papadogiannakis, Evangelos Markatos
In recent years, disinformation has increasingly proliferated across social networks. The firing of fact-checkers from Meta and the disbanding of Twitter's Trust and Safety Council…
COBRA: A Content-Agnostic Framework for Zero-Day Detection of Suspicious Domains
Alexandros Fourtounis, Emmanouil Papadogiannakis, Panagiotis Papadopoulos +2
The use of malicious domains is central to cyberattacks such as phishing, malware distribution, impersonation, and fraudulent transactions. Because domains are inexpensive to regis…
Ultraluminous X-ray sources in the first eROSITA survey I. Candidate catalogs
P. Weber, T. P. Roberts, S. Hämmerich +28
Ultraluminous X-ray sources (ULXs) are luminous non-nuclear X-ray point sources embedded in galaxies. Their luminosities exceeding 10^39 erg/s potentially require sub-Eddington acc…
Impact of Plasmonic Modes and Thermophysical Properties on the Double-Pulse Structuring of Highly-Ordered LIPSS for Biosensing Applications
G. D. Tsibidis, F. Fraggelakis, P. Lingos +5
The fabrication of highly ordered laser-induced periodic surface structures (LIPSS) on thin metallic films is dictated, predomaninatly, by a synergy of periodic electromagnetic ene…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
