SVOM discovery of a strong X-ray outburst of the blazar 1ES~1959+650 and multi-wavelength follow-up with the Neil Gehrels Swift observatory
A. Foisseau, A. Coleiro, S. Komossa +37
On December 6, 2024, 1ES 1959+650, one of the X-ray brightest blazars known, underwent a high-amplitude X-ray outburst detected by SVOM, the first such discovery with this mission.…
Extreme line profile variations in the repeating changing-look active galactic nucleus IRAS23226-3843
Wolfram Kollatschny, Dirk Grupe, Hartmut Winkler +7
IRAS23226-3843 has been identified as a highly variable Seyfert galaxy and even as a changing-look active galactic nucleus based on optical spectra. Here we present follow-up obser…
A Comparative Analysis of Multi-Criteria Decision-Making (MCDM) Methods
Nguyen Thi Thu Hien, Pham Huong Quynh, Vu Quang Minh
Multi-Criteria Decision-Making (MCDM) techniques have found widespread application across diverse fields. The rapid evolution of MCDM has led to the development of hundreds of meth…
Double-peaked Ca II traces a relativistic broad-line region disk in NGC 4593
M. W. Ochmann, P. M. Weilbacher, M. A. Probst +7
Double-peaked emission lines are observed in a small percentage of active galactic nuclei (AGN). These lines allow the determination of properties of the line-emitting region, know…
Detecting Unsuccessful Students in Cybersecurity Exercises in Two Different Learning Environments
Valdemar Švábenský, Kristián Tkáčik, Aubrey Birdwell +6
This full paper in the research track evaluates the usage of data logged from cybersecurity exercises in order to predict students who are potentially at risk of performing poorly.…
Investigating the {Origin} of the Absorption-Line Variability in Narrow-Line Seyfert 1 Galaxy WPVS 007
Kaylie S. Green, Sarah C. Gallagher, Karen M. Leighly +5
Broad Absorption Line Quasars (BALQs) are actively accreting supermassive black holes that have strong outflows characterized by broad absorption lines in their rest-UV spectra. Va…
