Titolo: | A Study of GRBs with Low-luminosity Afterglows | Autori: | Dereli, H. Boër, M. Gendre, B. AMATI, LORENZO Dichiara, S. Orange, N. B. |
Data pubblicazione: | 2017 | Rivista: | THE ASTROPHYSICAL JOURNAL | Numero: | 850 | Fascicolo: | 2 | Da pagina:: | 117 | Abstract: | We present a sample composed of the 41 faintest X-ray afterglows of the population of long gamma-ray bursts (lGRBs) with known redshift. We study their intrinsic properties (spectral index, decay index, distance, luminosity, isotropic radiated energy, and peak energy) and their luminosity distribution functions to assess whether they belong to the same population as the brighter afterglow events. We find that these events belong to a population of nearby ones, different from the general population of lGRBs. In addition, these events are faint during their prompt phase, and include the few possible outliers of the Amati relation. | URI: | http://hdl.handle.net/20.500.12386/26792 | URL: | https://iopscience.iop.org/article/10.3847/1538-4357/aa947d | ISSN: | 0004-637X | DOI: | 10.3847/1538-4357/aa947d | Bibcode ADS: | 2017ApJ...850..117D | Fulltext: | open |
