Evidence for a bursty -ray QPO in the neutrino-associated FSRQ PKS 1424418 using Fast Template Periodograms and Machine Learning
Aaron A. Maldonado, Alberto DomÃnguez, Adithiya Dinesh +4
Standard frequency-domain searches for quasi-periodic oscillations (QPOs) in active galactic nuclei generally assume sinusoidal variability. However, -ray blazar emission often…

The Quasar Main Sequence of Super-Eddington NLSy1 Galaxies
Alberto DomÃnguez, Alberto Domínguez, Suvendu Rakshit +3
The quasar main sequence, or Eigenvector 1 (EV1), describes the optical diversity of active galactic nuclei (AGN), with Narrow-Line Seyfert 1 (NLSy1) galaxies anchoring the high-ac…

Damped nonlinear Ginzburg-Landau equation with saturation. Part I. Existence of solutions on general domains
Pascal Bégout, Jesús Ildefonso DÃaz
We study the complex Ginzburg-Landau equation posed on possibly unbounded domains, including some singular and saturated nonlinear damping terms. This model interpolates between th…
