The transitional Type Ibn/IIn SN 2022pda, with pre-explosion outbursts and a double-peaked light curve
Y. -Z. Cai, A. Pastorello, R. Chiba +65
We report the results of a photometric and spectroscopic follow-up campaign of the unusual interacting supernova (SN) 2022pda. Precursor variability lasting days is obse…
Probing the interstellar medium toward GRB 221009A through X-ray dust scattering
B. Vaia, Ž. Bošnjak, A. Bracco +5
The observation of 21 X-ray dust-scattering rings around the extraordinarily bright gamma-ray burst (GRB) 221009A provides a unique opportunity to study the interstellar medium (IS…
A search for soft X-ray emission lines in the afterglow spectrum of GRB 221009A
Sergio Campana, Valentina Braito, Davide Lazzati +1
GRB 221009A was the Brightest gamma-ray burst Of All Time (BOAT), surpassing in prompt brightness all GRBs discovered in ~50 yr and in afterglow brightness in ~20 yr. We observed t…
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…
Long-term study of the 2020 magnetar-like outburst of the young pulsar PSRJ1846-0258 in Kes 75
Rajath Sathyaprakash, Nanda Rea, Francesco Coti Zelati +14
Magnetar-like activity has been observed in a large variety of neutron stars. PSR J1846-0258 is a young 327 ms radio-quiet pulsar with a large rotational power ($\sim 8 \times 10^{…
Evidence for a clumpy disc-wind in the star forming Seyfert\,2 galaxy MCG--03--58--007
G. A. Matzeu, V. Braito, J. N. Reeves +9
We report the results of a detailed analysis of a deep simultaneous \textit{XMM-Newton & NuSTAR} observation of the nearby () and bright ($L_{\rm bol}\sim3\…
Swift data hint at a binary Super Massive Black Hole candidate at sub-parsec separation
P. Severgnini, C. Cicone, R. Della Ceca +10
Dual/binary Supermassive Black Hole (SMBH) systems are the inevitable consequence of the current Lambda Cold Dark Matter cosmological paradigm. In this context, we discuss here the…
The chemical enrichment of long-GRB nurseries up to z=2
S. D. Vergani, J. Palmerio, R. Salvaterra +12
We investigate the existence of a metallicity threshold for the production of long gamma-ray bursts (LGRBs). We used the host galaxies of the Swift/BAT6 sample of LGRBs. We conside…
SN 2015bh: NGC 2770's 4th supernova or a luminous blue variable on its way to a Wolf-Rayet star?
C. C. Thöne, A. de Ugarte Postigo, G. Leloudas +13
Very massive stars in the final phases of their lives often show unpredictable outbursts that can mimic supernovae, so-called, "SN impostors", but the distinction is not always str…
Circular polarization in the optical afterglow of GRB 121024A
K. Wiersema, S. Covino, K. Toma +37
Gamma-ray bursts (GRBs) are most probably powered by collimated relativistic outflows (jets) from accreting black holes at cosmological distances. Bright afterglows are produced wh…
GRB 130427A: a Nearby Ordinary Monster
A. Maselli, A. Melandri, L. Nava +63
Long-duration Gamma-Ray Bursts (GRBs) are an extremely rare outcome of the collapse of massive stars, and are typically found in the distant Universe. Because of its intrinsic lumi…
GRB 100219A with X-shooter - abundances in a galaxy at z = 4.7
C. C. Thoene, J. P. U. Fynbo, P. Goldoni +24
Abundances of galaxies at redshifts z > 4 are difficult to obtain from damped Ly α (DLA) systems in the sightlines of quasars (QSOs) due to the Ly α forest blanketing and the low n…
A minor body falling onto a neutron star as an explanation for the unusual gamma-ray burst GRB 101225A
S. Campana, G. Lodato, P. D'Avanzo +17
The tidal disruption of a solar mass star around a supermassive black hole has been extensively studied analytically and numerically. In these events the star develops into an elon…
