Dual AGN and Multiple SMBH Systems in the Era of SKAO
Q. D'Amato, L. Cui, R. Deane +23
We present a radio-oriented review of current strategies for the detection and characterization of dual active galactic nuclei (DAGN) and supermassive black hole binaries (SMBHBs),…
Archival Multiband Gravitational-Wave Signals from Massive Black Hole Binary Mergers
Alexander W. Criswell, Stephen R. Taylor, Kris Pardo +4
While massive black hole binaries (MBHBs) merge at gravitational-wave frequencies above the pulsar timing array (PTA) sensitivity band, we show that they leave orphaned low-frequen…
J-PAS: unprecedented precision in stellar populations of diffuse tidal features
Sepideh Eskandarlou, Mohammad Akhlaghi, Francisco Arizo-Borillo +38
Galaxies frequently interact with nearby systems, a process that can significantly alter their morphology and star formation activity. However, spectroscopic studies of their faint…
The Yasone catalogue: three new Milky Way satellites and 17 further hypercompact candidates
J. Untzaga, M. Mezcua, S. Bonoli +5
We present the discovery of three new low-latitude (|b| ~ 20) Milky Way satellites: Yasone-1, Yasone-2, and Yasone-3. They were identified in our search for compact stell…
Well-being and career instability across genders in the Spanish Astronomical Society
Maritza A. Lara-Lopez, I. Rebollido, A. Vidal-Garcia +9
We present the results of a comprehensive survey conducted among members of the Spanish Astronomical Society (Sociedad Espanola de Astronomia, SEA) to assess well-being, profession…
Detection of a universal core-halo transition in dwarf galaxies as predicted by Bose-Einstein dark matter
Alvaro Pozo, Tom Broadhurst, Ivan de Martino +4
The presence of large dark matter cores in dwarf galaxies has long been puzzling and many are now known to be surrounded by an extensive halo of stars. Distinctive core-halo struct…
