Binary Black Hole Parameter Estimation with Hybrid CNN-Transformer Neural Networks
Panagiotis N. Sakellariou, Spiros V. Georgakopoulos, Sotiris Tasoulis +1
The detection of gravitational waves has revolutionized our ability to explore fundamental aspects of the Universe. Traditionally, modeled gravitational-wave signals have been iden…
On the Spectrum of Certain Hadamard Manifolds
Werner Ballmann, Mayukh Mukherjee, Panagiotis Polymerakis
We show the absolute continuity of the spectrum and determine the spectrum as a set for two classes of Hadamard manifolds and for specific domains and quotients of one of the class…
From Data Harvesting to Querying for Making Urban Territories Smart
Genoveva Vargas-Solar, Ana-Sagrario Castillo-Camporro, José Zechinelli-Martini +1
This chapter provides a summarized, critical and analytical point of view of the data-centric solutions that are currently applied for addressing urban problems in cities. These so…
Singularities and Phenomenological aspects of Asymptotic Safe Gravity
Vasilios Zarikas, Georgios Kofinas
Asymptotic Safety (AS) Program for quantum gravity keeps the same fields and symmetries with General Relativity and studies the associated gravitational action as a fundamental par…
High resolution observations with Artemis--JLS, (II) Type IV associated intermediate drift bursts
C. Bouratzis, A. Hillaris, C. E. Alissandrakis +5
Aims. We examined the characteristics of isolated intermediate drift bursts (IMDs) and their morphologies on dynamic spectra, in particular the positioning of emission and absorpti…
Detection of spike-like structures near the front of type-II bursts
S. Armatas, C. Bouratzis, A. Hillaris +6
Aims. We examine high time resolution dynamic spectra for fine structures in type II solar radio bursts Methods. We used data obtained with the (SAO) receiver of the Artemis-JLS (A…
