Search for Extended GeV Sources in the Inner Galactic Plane
S. Abdollahi, F. Acero, A. Acharyya +108
The recent detection of extended -ray emission around middle-aged pulsars is interpreted as inverse-Compton scattering of ambient photons by electron-positron pairs escaping the…
A Repeating Fast Radio Burst Source in a Low-Luminosity Dwarf Galaxy
Danté M. Hewitt, Mohit Bhardwaj, Alexa C. Gordon +48
We present the localization and host galaxy of FRB 20190208A, a repeating source of fast radio bursts (FRBs) discovered using CHIME/FRB. As part of the PRECISE repeater localizatio…
GRB 221009A: the B.O.A.T Burst that Shines in Gamma Rays
M. Axelsson, M. Ajello, M. Arimoto +151
We present a complete analysis of Fermi Large Area Telescope (LAT) data of GRB 221009A, the brightest Gamma-Ray Burst (GRB) ever detected. The burst emission above 30 MeV detected…
High-resolution imaging of the evolving bipolar outflows in symbiotic novae: The case of the RSOphiuchi 2021 nova outburst
R. Lico, M. Giroletti, U. Munari +6
The recurrent and symbiotic nova RS Ophiuchi (RSOph) underwent a new outburst phase during August 2021, about 15 years after the last event that occurred in 2006. This outburst rep…
Revealing faint compact radio jets at redshifts above 5 with very long baseline interferometry
Máté Krezinger, Giovanni Baldini, Marcello Giroletti +6
Over the past two decades, our knowledge of the high-redshift (z > 5) radio quasars has expanded, thanks to dedicated high-resolution very long baseline interferometry (VLBI) obser…
A JVLA, LOFAR, e-Merlin, VLBA and EVN study of RBS 797: can binary SMBHs explain the outburst history of the central radio galaxy?
Francesco Ubertosi, Marcello Giroletti, Myriam Gitti +9
We present a multi-frequency (144 MHz - 9 GHz) and multi-scale (5 pc - 50 kpc) investigation of the central radio galaxy in RBS 797, by means of JVLA, LOFAR (with international sta…
