On The Nature of Einstein Probe Transient EP250916a: Insights from X-ray, Optical, and Radio Observations

Gaurava K. Jaisawal, Giulia Illiano, Francesco Carotenuto +7

We report multi-wavelength studies of the transient EP250916a, detected by the Einstein Probe on 2025 September 16. Located at low Galactic latitude, the source exhibited a rapid X…

X-Ray Polarization from the Atoll 4U 1735-44 Suggests a Low Inclination

M. A. Díaz Teodori, A. Bobrikova, A. Gnarini +17

X-ray polarimetry is a new tool capable of probing the geometry of accretion onto weakly magnetized neutron stars. Here we present the first X-ray spectropolarimetric results from…

First detection of VHE gamma-ray signal from the FSRQ TON 0599

MAGIC Collaboration, K. Abe, S. Abe +245

TON\,0599 (z=0.7247) belongs to the few flat spectrum radio quasars (FSRQs) detected in the very high energy (VHE, \,GeV) gamma-ray band. Its redshift makes it currently o…

Multiband optical variability on diverse timescales of the blazar Ton 599 from 2011 to 2023

O. Vince, C. M. Raiteri, M. Villata +72

(Shortened)Context: We analyze the optical variability of the FSRQ Ton 599 using BVRI photometry from the WEBT collaboration (2011-2023), complemented by photometric and spectrosco…
