The parameters of optical transients were calculated in the comoving frame, and then a search for pair correlations between them was conducted. A statistical analysis showed a strong correlation between the peak luminosity and the redshift both for pure afterglows and for events with residual gamma activity, which cannot be explained as an effect of observational selection.This suggests a cosmological evolution of the parameters of the local interstellar medium around the sources of the gamma-ray burst. In the models of forward and reverse shock waves, a relation between the density of the interstellar medium and the redshift was built for gamma-ray burst afterglows, leading to a power-law dependence of the star-formation rate at regions around GRBs on redshift with a slope of about 6.","PeriodicalId":335082,"journal":{"name":"Gamma-ray Bursts: 15 Years of GRB Afterglows","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123297276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The joint Russian-American Konus-Wind experiment, which has already been operating for more than 18 years, provides important and often unique data regarding GRB characteristics in 20 keV – 15 MeV energy range. These investigations were complemented by several Konus and Helicon experiments onboard Russian near-Earth spacecraft.

This is due to the fact, that short GRBs exhibit variability on time scales\u0000 shorter than 1 ms and count rate, measured at such short time scales, is not sufficient\u0000 for reliable spectroscopy even for the brightest events. In this situation, any new possibility to look at spectral evolution of short GRBs on\u0000 sub-millisecond time scales in terms of spectral parameters, may provide more solid\u0000 background for theoretical analysis.

Fast optical observations allowed us to observe line variability and to derive the distance and composition of the absorbing medium. However, given the huge GRB ionizing flux, this medium starts showing up in the optical spectra only at relatively large distances (100 pc). A complementary view comes from the X-ray band, where the overall contribution of all metals bends the power law X-ray afterglow spectrum. We will review and compare optical and X-ray studies of the circumbust medium.","PeriodicalId":335082,"journal":{"name":"Gamma-ray Bursts: 15 Years of GRB Afterglows","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132553192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The observed rate of the MAXI GRBs is about one event per month. This rate is comparable to a past observation with larger effective area and larger field of view. The fact indicates that MAXI has better sensitivity to observe GRBs because of low background. The distribution of the spectral hardness of MAXI GRBs is similar to the results of a past instrument, which is sensitive to similar energy range.","PeriodicalId":335082,"journal":{"name":"Gamma-ray Bursts: 15 Years of GRB Afterglows","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116989057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
