The Unanticipated Phenomenology of the Blazar PKS~2131021: A Unique Super-Massive Black Hole Binary Candidate
S. O'Neill, S. Kiehlmann, A. C. S. Readhead +24
Most large galaxies host supermassive black holes in their nuclei and are subject to mergers, which can produce a supermassive black hole binary (SMBHB), and hence periodic signatu…
Back to quiescence: post-outburst evolution of the pulsar J1119-6127 and its wind nebula
Harsha Blumer, Samar Safi-Harb, Alice Borghese +4
We report on the analysis of a deep Chandra observation of the high-magnetic field pulsar (PSR) J1119-6127 and its compact pulsar wind nebula (PWN) taken in October 2019, three yea…
The First CHIME/FRB Fast Radio Burst Catalog
FRB Collaboration, Mandana Amiri, Bridget C. Andersen +73
We present a catalog of 536 fast radio bursts (FRBs) detected by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) Project between 400 and 800 MHz fro…
Hidden treasures in the unknown 3CR extragalactic radio sky: a multi-wavelength approach
V. Missaglia, F. Massaro, E. Liuzzo +17
We present the analysis of multi-wavelength observations of seven extragalactic radio sources, listed as unidentified in the Third Cambridge Revised Catalog (3CR). X-ray observatio…
Constraining the AGN duty cycle in the cool-core cluster MS 0735.6+7421 with LOFAR data
Nadia Biava, Marisa Brienza, Annalisa Bonafede +6
MS 0735.6+7421 is a galaxy cluster which hosts a central radio galaxy with a very steep spectrum, produced by one of the most powerful known jetted active galactic nuclei (AGN). Th…
Reactivation of the high-magnetic field pulsar PSR J1846--0258 with magnetar-like bursts
Harsha Blumer, Samar Safi-Harb, Maura A. McLaughlin +1
We report on the 2020 reactivation of the energetic high-magnetic field pulsar PSR J1846-0258 and its pulsar wind nebula (PWN) after 14 years of quiescence with new Chandra and Gre…
