LeMMINGs IV: The X-ray properties of a statistically-complete sample of the nuclei in active and inactive galaxies from the Palomar sample

D. R. A. Williams, M. Pahari, R. D. Baldi +22

All 280 of the statistically-complete Palomar sample of nearby (<120 Mpc) galaxies dec > 20 degrees have been observed at 1.5 GHz as part of the LeMMINGs e-MERLIN legacy survey. He…

Daily variability at milli-arcsecond scales in the radio quiet NLSy1 Mrk 110

Francesca Panessa, Miguel Perez-Torres, Lorena Hernandez-Garcia +14

The origin of radio emission in the majority of Active Galactic Nuclei (AGN) is still poorly understood. Various competing mechanisms are likely involved in the production of radio…

LeMMINGs. III. The e-MERLIN Legacy Survey of the Palomar sample. Exploring the origin of nuclear radio emission in active and inactive galaxies through the [O III] -- radio connection

R. D. Baldi, D. R. A. Williams, R. J. Beswick +31

What determines the nuclear radio emission in local galaxies? We combine optical [O III] line emission, robust black hole (BH) mass estimates, and high-resolution e-MERLIN 1.5-GHz…

The PG-RQS survey. Building the radio spectral distribution of radio-quiet quasars. I. The 45-GHz data

R. D. Baldi, A. Laor, E. Behar +4

The origin of the radio emission in radio-quiet quasars (RQQs) remains unclear. Radio emission may be produced by a scaled-down version of the relativistic jets observed in radio-l…

The Fast Radio Burst FRB 20201124A in a star forming region: constraints to the progenitor and multiwavelength counterparts

L. Piro, G. Bruni, E. Troja +16

We present the results of a multiwavelength campaign of FRB 20201124A, the third closest repeating fast radio burst recently localized in a nearby (z=0.0978) galaxy. Deep VLA obser…

Hard X-ray selected giant radio galaxies -- III. The LOFAR view

G. Bruni, M. Brienza, F. Panessa +12

Giant radio galaxies (GRGs), with extended structures reaching hundreds of kpc, are among the most spectacular examples of ejection of relativistic plasma from super-massive black…
