Unveiling the Multifaceted GRB 200613A: Prompt Emission Dynamics, Afterglow Evolution, and the Host Galaxy's Properties
Shao-Yu Fu, Dong Xu, Wei-Hua Lei +17
We present our optical observations and multi-wavelength analysis of the GRB\,200613A detected by \texttt{Fermi} satellite. Time-resolved spectral analysis of the prompt -ray em…
Rapid Response Mode observations of GRB 160203A: Looking for fine-structure line variability at z=3.52
G. Pugliese, A. Saccardi, V. D Elia +26
Gamma-ray bursts are the most energetic known explosions. Despite fading rapidly, they allow to measure redshift and important properties of their host-galaxies. We report the phot…
HI and CO spectroscopy of the unusual host of GRB 171205A: A grand design spiral galaxy with a distorted HI field
A. de Ugarte Postigo, M. Michalowski, C. C. Thoene +22
GRBs produced by the collapse of massive stars are usually found near the most prominent star-forming regions of star-forming galaxies. GRB 171205A happened in the outskirts of a s…
The host of GRB 171205A in 3D -- A resolved multiwavelength study of a rare grand-design spiral GRB host
C. C. Thöne, A. de Ugarte Postigo, L. Izzo +17
Long GRB hosts at z<1 are usually low-mass, low metallicity star-forming galaxies. Here we present the until now most detailed, spatially resolved study of the host of GRB 171205A,…
The fast X-ray transient EP240315a: a z ~ 5 gamma-ray burst in a Lyman continuum leaking galaxy
Andrew J. Levan, Peter G. Jonker, Andrea Saccardi +73
The nature of the minute-to-hour long Fast X-ray Transients (FXTs) localised by telescopes such as Chandra, Swift, and XMM-Newton remains mysterious, with numerous models suggested…
Varying linear polarisation in the dust-free GRB 210610B
J. F. Agüí Fernández, A. de Ugarte Postigo, C. C. Thöne +19
Long gamma ray bursts (GRBs) are produced by the collapse of some very massive stars, which emit ultra-relativistic jets. When the jets collide with the interstellar medium they de…
Fires in the deep: The luminosity distribution of early-time gamma-ray-burst afterglows in light of the Gamow Explorer sensitivity requirements
D. A. Kann, N. E. White, G. Ghirlanda +58
Gamma-ray bursts (GRBs) are ideal probes of the Universe at high redshift (z > 5), pinpointing the locations of the earliest star-forming galaxies and providing bright backlights t…
