X-ray and optical decline of the intermediate mass black hole HLX-1
Roberto Soria, Maya Garbaccio Gili, Francesco Massaro +2
The paper presents new Hubble, Chandra, and Swift observations of the intermediate‑mass black hole candidate HLX‑1, showing a rapid X‑ray decline while the optical/UV emission fade…
Powerful Radio Sources in the Southern Sky. IV. Observations of the G4Jy-3CRE Catalog with the Australian Square Kilometre Array Pathfinder
Siegfried A. Gawenda, Juan P. Madrid, Francesco Massaro +19
A recent 2023 paper by Massaro et al. introduced the G4Jy-3CRE, a new catalog of the brightest radio sources in the southern hemisphere that serve as a southern equivalent to the T…
The GLEAM 4-Jy (G4Jy) Sample: IV. Multiwavelength data and analysis
Sarah V. White, Precious K. Sejake, Kshitij Thorat +17
We provide an updated 'multiwavelength' version of the G4Jy catalogue (available at https://github.com/svw26/G4Jy, https://zenodo.org/communities/g4jy/records, and through VizieR),…
The GLEAM 4-Jy (G4Jy) Sample: III. Further host-galaxy identification, and redshift assessment
Sarah V. White, Precious K. Sejake, Kshitij Thorat +17
In this paper we present 127 new host-galaxy identifications for G4Jy sources (S_151MHz > 4 Jy), based on radio images from MeerKAT, the Very Large Array Sky Survey (VLASS), and th…
SALT spectroscopic follow-up of the G4Jy Sample
Sarah V. White, Kshitij Thorat, Moses Mogotsi +9
The GLEAM 4-Jy (G4Jy) Sample is a thorough compilation of the 'brightest' radio sources in the southern sky (Declination < 30 deg), as measured at 151 MHz (S > 4.0 Jy) with the Mur…
The MUSE view of Lyman- nebulae in High redshift Radio Galaxies
Miguel Coloma Puga, Barbara Balmaverde, Alessandro Capetti +2
We present the results of VLT/MUSE integral field spectroscopic observations of the Ly emission nebulae associated with 11 high redshift () radio galaxies (HzRGs)…
