GRB 180728A and SN 2018fip: the nearest high-energy cosmological gamma-ray burst with an associated supernova
A. Rossi, L. Izzo, K. Maeda +29
The long GRB 180728A, at a redshift of , stands out due to its high isotropic energy of erg, in contrast with most events at redshif…
The puzzling long GRB 191019A: Evidence for Kilonova Light
G. Stratta, A. M. Nicuesa Guelbenzu, S. Klose +11
GRB 191019A was a long Gamma-ray burst (GRB) lasting about 65 s and, as such, originally thought to be linked to a core-collapse supernova. However, even though follow-up observati…
Massive stars exploding in a He-rich circumstellar medium X. Flash spectral features in the Type Ibn SN 2019cj and observations of SN 2018jmt
Z. -Y. Wang, A. Pastorello, K. Maeda +48
We present optical and near-infrared observations of two Type Ibn supernovae (SNe), SN 2018jmt and SN 2019cj. Their light curves have rise times of about 10 days, reaching an absol…
A study in scarlet -- II. Spectroscopic properties of a sample of Intermediate Luminosity Red Transients
G. Valerin, A. Pastorello, E. Mason +65
We investigate the spectroscopic characteristics of Intermediate Luminosity Red Transients (ILRTs), a class of elusive objects with peak luminosity between that of classical novae…
A study in scarlet -- I. Photometric properties of a sample of Intermediate Luminosity Red Transients
G. Valerin, A. Pastorello, A. Reguitti +57
We investigate the photometric characteristics of a sample of Intermediate Luminosity Red Transients (ILRTs), a class of elusive objects with peak luminosity between that of classi…
The Optical/NIR afterglow of GRB 111209A: Complex yet not Unprecedented
D. A. Kann, P. Schady, F. Olivares E. +24
Afterglows of Gamma-Ray Bursts (GRBs) are simple in the most basic model, but can show many complex features. The ultra-long duration GRB 111209A, one of the longest GRBs ever dete…
Prompt emission of GRB 121217A from gamma-rays to the NIR
J. Elliott, H. -F. Yu, S. Schmidl +20
The mechanism that causes the prompt-emission episode of gamma-ray bursts (GRBs) is still widely debated despite there being thousands of prompt detections. The favoured internal s…
Afterglow rebrightenings as a signature of a long-lasting central engine activity? The emblematic case of GRB 100814A
M. Nardini, J. Elliott, R. Filgas +12
In the past few years the number of well-sampled optical to NIR light curves of long Gamma-Ray Bursts (GRBs) has greatly increased particularly due to simultaneous multi-band image…
The low-extinction afterglow in the solar-metallicity host galaxy of gamma-ray burst 110918A
J. Elliott, T. Krühler, J. Greiner +21
Metallicity is theoretically thought to be a fundamental driver in gamma-ray burst (GRB) explosions and energetics, but is still, even after more than a decade of extensive studies…
The unusual afterglow of the Gamma-Ray Burst 100621A
J. Greiner, T. Krühler, M. Nardini +27
In order to constrain the broad-band spectral energy distribution of the afterglow of GRB 100621A, dedicated observations were performed in the optical/near-infrared with the 7-cha…
Clustering of galaxies around GRB sight-lines
Vladimir Sudilovsky, Jochen Greiner, Arne Rau +11
There is evidence of an overdensity of strong intervening MgII absorption line systems distributed along the lines of sight towards GRB afterglows relative to quasar sight-lines. I…
GRB 091029: At the limit of the fireball scenario
R. Filgas, J. Greiner, P. Schady +20
Using high-quality, broad-band afterglow data for GRB 091029, we test the validity of the forward-shock model for gamma-ray burst afterglows. We used multi-wavelength (NIR to X-ray…
The late-time afterglow of the extremely energetic short burst GRB 090510 revisited
A. Nicuesa Guelbenzu, S. Klose, T. Kruehler +16
The discovery of the short GRB 090510 has raised considerable attention mainly because it had a bright optical afterglow and it is among the most energetic events detected so far w…
The SEDs and Host Galaxies of the dustiest GRB afterglows
T. Krühler, J. Greiner, P. Schady +18
(Abridged) Until recently the information inferred from gamma-ray burst follow-up observations was mostly limited to optically bright afterglows, biasing all demographic studies ag…
GRB 090426: Discovery of a jet break in a short burst afterglow
A. Nicuesa Guelbenzu, S. Klose, A. Rossi +14
Context: The link between the duration of GRBs and the nature of their progenitors remains disputed. Short bursts (with durations of less than ~2 s) are less frequently observed, t…
The two-component jet of GRB 080413B
R. Filgas, T. Kruehler, J. Greiner +16
The quick and precise localization of GRBs by the Swift telescope allows the early evolution of the afterglow light curve to be captured by ground-based telescopes. With GROND meas…
Photometric redshifts for GRB afterglows from GROND and Swift/UVOT
T. Krühler, P. Schady, J. Greiner +18
We present a framework to obtain photometric redshifts (photo-zs) for gamma-ray burst afterglows. Using multi-band photometry from GROND and Swift/UVOT, photo-zs are derived for fi…
