A Broadband X-ray Analysis and Optical Counterpart Search of IC5052 ULX
Nabil Brice, Dominic J. Walton, Felix Fürst +10
We present broadband X-ray spectral and timing analysis of the Ultra-luminous X-ray source (ULX) in IC5052 using simultaneous XMM-Newton and NuSTAR observations from 2022, suppleme…
Peering through the dip: IXPE unveils the extended scattering environment of GX 13+1
Alessandro Di Marco, Fabio La Monaca, Luigi Stella +17
Neutron star low-mass X-ray binaries feature complex accretion geometries, often including an accretion disk corona or disk winds. Here, a study of the highly inclined dipping sour…
Correlation between active regions' spectra at high radio frequencies and solar flare occurrences
Sara Mulas, Alberto Pellizzoni, Marco Marongiu +31
High radio frequencies observations with the Italian network of large single-dish radio telescopes resulted in ~450 solar images between 2018 and 2023 in K-band frequency range (18…
The statistical properties of the cross spectrum
Edward J. R. Nathan, Adam Ingram, Daniela Huppenkothen +2
The cross spectrum encodes the correlated variability between two time signals. In recent years, the cross spectrum has been used to study astronomical sources, particularly in the…
Magnetic-field Order in the Southwestern Rim of RCW 86 Constrained Using X-Ray Polarimetry
Stefano Silvestri, Dmitry Prokhorov, Jacco Vink +97
RCW 86 is a supernova remnant whose origin has recently been linked to an off-center explosion within a cavity created by its progenitor star. In the southwestern region, the forwa…
4U 1556-60 as a very faint neutron star X-ray binary at 700 pc with an undetected radio jet
Eliot C. Pattie, Thomas J. Maccarone, Thomas Russell +3
4U 1556-60 is a low-mass X-ray binary that was discovered more than 50 years ago as a persistent X-ray source; however, very little was known about it. Recently, Gaia obtained a pa…
