The multi-planet system TOI-5624: Four transiting sub-Neptunes with an outer companion revealed by transit-timing variations

A. Bonfanti, D. Gandolfi, P. Leonardi +96

Following the 2022 alert of a TESS object of interest transiting TOI-5624 (a G7 V star 100 pc away), a CHEOPS campaign in 2023 detected four planetary signals at $P_b\approx3…

The Northern Cross Fast Radio Burst project: V. Search for transient radio emission from Galactic magnetars

A. Geminardi, P. Esposito, G. Bernardi +21

Context. The radio emission from magnetars is poorly understood and poorly characterized observationally, in particular for what concerns single pulses and sporadic events. The int…

Periodic Gamma-ray Modulation of the blazar PG 1553+113 Confirmed by Fermi-LAT and Multi-wavelength Observations

S. Abdollahi, L. Baldini, G. Barbiellini +98

A 2.1-year periodic oscillation of the gamma-ray flux from the blazar PG 1553+113 has previously been tentatively identified in almost 7 year of data from the Fermi Large Area Tele…

The Northern Cross Fast Radio Burst project IV. Multi-wavelength study of the actively repeating FRB 20220912A

D. Pelliciari, G. Bernardi, M. Pilia +26

Fast radio bursts (FRBs) are energetic, millisecond-duration radio pulses observed at extragalactic distances and whose origins are still a subject of heated debate. A fraction of…

Multi-wavelength observations of the lensed quasar PKS 1830211 during the 2019 -ray flare

S. Vercellone, I. Donnarumma, C. Pittori +32

PKS 1830211 is a -ray emitting, high-redshift (z ), lensed flat-spectrum radio quasar. During the period mid-February to mid-April 2019, this source underw…

The Northern Cross Fast Radio Burst project -- III. The FRB-magnetar connection in a sample of nearby galaxies

Davide Pelliciari, Gianni Bernardi, Maura Pilia +18

Fast radio bursts (FRBs) are millisecond radio transients observed at cosmological distances. The nature of their progenitors is still a matter of debate, although magnetars are in…
