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…

Tracking optical variability and outflows across the accretion states of the black hole transient MAXI J1820+070

M. C. Baglio, K. Alabarta, D. M. Russell +10

We present a study of the minute-timescale optical variability and spectroscopic outflow signatures in the black hole X-ray binary MAXI J1820+070 during its 2018 outburst and re-br…

Powerful Radio Sources in the Southern Sky. II. A SWIFT X-Ray Perspective

F. Massaro, S. V. White, A. Paggi +18

We recently constructed the G4Jy-3CRE, a catalog of extragalactic radio sources based on the GLEAM 4-Jy (G4Jy) sample, with the aim of increasing the number of powerful radio galax…

Powerful Radio Sources in the Southern Sky. I. Optical Identifications

F. Massaro, S. V. White, A. Garcia-Perez +18

Since the early sixties, our view of radio galaxies and quasars has been drastically shaped by discoveries made thanks to observations of radio sources listed in the Third Cambridg…

Optical spectroscopic observations of gamma-ray blazar candidates. X. Results from the 2018--2019 SOAR and OAN-SPM observations of blazar candidates of uncertain type

Raniere de Menezes, Raul A. Amaya-Almazán, Ezequiel J. Marchesini +14

The fourth Fermi Large Area Telescope Source Catalog (4FGL) lists over 5000 gamma-ray sources with statistical significance above 4. About 23% of the sources listed in this cata…

Optical spectroscopic observations of gamma-ray blazar candidates. IX. Optical archival spectra and further observations from SOAR and OAGH

H. A. Peña-Herazo, F. Massaro, V. Chavushyan +11

Nearly one-third of the sources in the -LAT catalogs lack a lower energy counterpart, hence being referred as unidentified/unassociated gamma-ray sources (UGSs). In order to…
