The Diversity of Light Curves of Supernovae Associated with Gamma-Ray Bursts
P. 74–91.
Belkin S., Pozanenko Alexei
More than 10000 gamma-ray bursts (GRBs) have been detected since discovery. Long-term observations of about 850 GRB afterglow in optic since 1998 have shown that a core-collapse supernova (SN) accompanies about 50 nearby GRB sources. We have collected about two dozen SNe’ multicolor light curves associated with GRBs. The sample is based on published data, obtained during observations of GRB-SN cases by ground-based observatories all around the world including our own observations. A description of the procedure for the extraction of the SN’s light curve, its analysis, and phenomenological classification of SNs are presented. We also discuss the current status and problems of investigations of SN associated with GRB.

Gamma-ray bursts (GRBs), particularly those detected by wide-field instruments such as the Fermi/GBM, pose challenges for optical follow-up because of their large initial localization regions, leaving many GRBs without identified afterglows. The Gravitational-wave Optical Transient Observer (GOTO), with its wide field of view, dual-site coverage, and robotic rapid-response capability, bridges this gap by rapidly identifying ...

We present the most complete up-to-date sample of supernovae associated with gamma-ray bursts (GRB-SNe) for which the peak time of the SN light curve and the peak absolute magnitude have been found. The sample contains 44 SNe. We have searched for correlations between the parameters of the GRB-SN $$V$$-band brightness peak (the rest-frame $$V$$-band absolute magnitude $$M_{V}$$) and ...

Magnetorotational processes can significantly affect the dynamics of core-collapse supernovae, resulting to magnetically driven jet-like explosions. The magnetic field topology of progenitor stellar cores is believed to be quite complex and is not known precisely. Such complex structures may differ substantially from usual dipole or quadrupole field, which may cause to additional anisotropy of magnetorotational ...

We present the software aware for automatic scheduling the observations with the ground based network of optical telescopes GRB-IKI-FuN (extendable on other facilities). It was designed to provide the optimal coverage of large uncertainty contours of LIGO/Virgo/KAGRA (LVK) gravitational wave events, and gamma-ray bursts (GRBs), detected by space missions, which is crucial for fast look-up ...

We present the results of our analysis of multiwavelength observations for the long gamma-ray burst GRB 200829A. The burst redshift z≈1.29±0.04 has been determined photometrically at the afterglow phase. In gamma rays the event is one of the brightest (in isotropic equivalent), Eiso≳1054 erg. The multicolor light curve of the GRB 200829A afterglow is characterized ...

We present full photometric coverage and spectroscopic data for soft gamma-ray burst GRB 201015A with a redshift z = 0.426. Our data span a time range of 85 d following the detection of GRB. These observations revealed an underlying supernova SN 201015A with a maximum at 8.54±1.48 d (rest frame) and an optical peak absolute ...

Bolometric light curves play an important role in understanding the underlying physics of various astrophysical phenomena, as they allow for a comprehensive modelling of the event and enable comparison between different objects. However, constructing these curves often requires the approximation and extrapolation from multicolour photometric observations. In this study, we introduce vector Gaussian processes as ...

Long gamma-ray bursts are produced by energy dissipation within ultra-relativistic jets launched by newborn black holes after the collapse of a peculiar class of massive stars. Right after the luminous and highly variable gamma-ray emission, a multi-wavelength afterglow is released by external dissipation of the jet energy in the medium that surrounds the progenitor star. ...

Detection, observation and description of supernovae associated with gamma-ray bursts are currently topical tasks in the field of transient phenomena. From the moment an assumption is made about the relationship of the gamma-ray burst with a supernova to obtaining the parameters of the latter, many steps must be taken, and each of them introduces uncertainty ...

Identification and following study of optical transients (OTs) associated with cosmic gamma-ray bursts (GRBs) and gravitational wave (GWs) events is a relevant research problem of multi-messenger astronomy. Since their first discovery, one of the greatest challenges is the localisation uncertainty. The sources of OTs are initially localised with space gamma and X-ray telescopes or ground-based ...

We obtained well-sampled optical photometry of GRB 110213A, including Swift/UVOT and XRT. Combining our data from those of other ground-based telescopes, we present 15 optical multicolor light curves showing similar shapes with two peaks. In contrast, in the X-ray band, only a single peak is observed between the two optical peaks. Temporal and spectral analysis ...

Gamma-ray bursts (GRBs) are classified into long and short events. Long GRBs (LGRBs) are associated with the end states of very massive stars, while short GRBs (SGRBs) are linked to the merger of compact objects. GRB 200826A was a peculiar event, because by definition it was an SGRB, with a rest-frame duration of 1/40.5 s. ...

The SNAD team reports the discovery of SNAD160 (AT2018lzi) within the Zwicky Transient Facility third data release. The transient has been found using the active anomaly detection algorithm, an adaptive learning strategy aimed at incorporating expert knowledge into machine learning models. Our preliminary analysis shows that SNAD160 could be a superluminous supernova powered by a ...
