High-redshift GRB 140304A at z = 5.282 with flaring activity: A multi-wavelength study

Shashi. B. Pandey, Amit. K. Ror, A. J. Castro-Tirado +48

Context. This article presents a detailed multi-wavelength analysis of GRB 140304A at z = 5.282, having uncommon late-time flaring features. The aim is to study GRB 140304A and oth…

An extremely bright slow-rising afterglow from an off-axis jet in GRB 260310A

Yu-Han Yang, Roberto Ricci, Eleonora Troja +31

We present a multi-wavelength study of GRB 260310A, a nearby long-duration gamma-ray burst at associated with a broad-lined Type Ic supernova. Despite its modest pro…

Ellipsoidal modulation and multi-wavelength activity in the pre-cataclysmic binary RX J1553.0+4457

S. -Y. Wu, M. Gritsevich, Q. -H. Lao +39

RX J1553.0+4457 (TMTS J15530469+4457458) is a detached post-common-envelope binary containing a cool white dwarf and an active late-type companion. We present a multi-wavelength st…

Multi-wavelength picture of the misaligned BL Lac object 3C 371

J. Otero-Santos, C. M. Raiteri, A. Tramacere +52

The BL Lac object 3C 371 is one of the targets that are regularly monitored by the Whole Earth Blazar Telescope (WEBT) Collaboration to study blazar variability on both short and l…

A wiggling filamentary jet at the origin of the blazar multi-wavelength behaviour

C. M. Raiteri, M. Villata, M. I. Carnerero +96

Blazars are beamed active galactic nuclei known for their strong multi-wavelength variability on timescales from years down to minutes. We aim to investigate the suitability of the…
