Early Optical Follow-up of Gamma-Ray Bursts: The Critical Role of Robotic Telescopes
Rahul Gupta, Judith Racusin, Gor Oganesyan +26
Gamma-ray bursts (GRBs) are the most luminous electromagnetic explosions in the Universe, and offer unique laboratories for studying relativistic jets, compact-object formation, pa…
EP251023a: A fast X-ray transient featuring a magnetar-powered optical internal plateau followed by a steep decay
Shuai-Qing Jiang, Dong Xu, Wei-Hua Lei +33
EP251023a is an extragalactic fast X-ray transient (eFXT) detected solely by EP without a gamma-ray counterpart. The prompt emission consists of a main emission with a duration $T_…
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…
Consistency between dynamical modeling and photometrically derived masses of fireballs
Eloy Peña-Asensio, Maria Gritsevich
We present a three-point inverse solution for reconstructing meteoroid deceleration and mass-loss histories from sparse observations constrained only by the entry, peak-brightness,…
Stochastic Optical Variability and an rms-flux Relation in the Intermediate Polar EP240309a
S. -Y. Wu, Y. -D. Hu, I. Perez-Garcia +18
Magnetic cataclysmic variables provide a natural laboratory for studying how accretion interacts with compact-object magnetospheres and generates stochastic variability. We present…
Long-term outburst activity of comet 17P/Holmes and constraints on ejecta size distributions
Maria Gritsevich, Marcin Wesołowski, Josep M. Trigo-Rodríguez +4
A quantitative understanding of cometary outbursts requires robust constraints on the size distribution of ejected particles, which governs outburst dynamics and underpins estimate…
The First Instrumentally Documented Fall of an Iron Meteorite: atmospheric trajectory and ground impact
Jarmo Moilanen, Maria Gritsevich, Jaakko Visuri
Iron meteorite falls are rare compared to stony meteorites, and until recently no iron meteorite had a reliably determined pre-atmospheric orbit. This changed on 2020 November 7, w…
Distance-Independent Atmospheric Refraction Correction for Accurate Retrieval of Fireball Trajectories
Jaakko Visuri, Maria Gritsevich, Janne Sievinen
Accurate determination of fireball direction is essential for retrieving trajectories and velocities. Errors in these measurements have significant implications, affecting the calc…
Minutes-long soft X-ray prompt emission from a compact object merger
An Li, Chen-Wei Wang, Niccolò Passaleva +75
Compact object mergers are multi-messenger sources and known progenitors of some gamma-ray bursts, bright flashes of high-energy radiation powered by a central engine, either an ac…
