Abstract

Gama-ışın patlamaları (GIP) evrendeki en enerjik olaylardır. Bu patlamalar, ana ışınım ve ardıl ışınım olarak iki bileşen halinde gözlenirler. Ardıl ışınım fiziksel parametreleri kullanılarak afterglowpy yazılımı aracılığıyla sentetik ışık eğrileri üretilebilir. Bu çalışmada, farklı jet modelleri kullanarak (Silindir şapka jet modeli (Top hat jet model), Gaussyan jet modeli (Gaussian jet model) ve Güç kanunu jet modeli (Power law jet model)) afterglowpy ile Swift - XRT ile gözlenmiş X-ışın ardıl ışınımları modellendi. Afterglowpy jet modellerini veriye doğrudan uygulanabilen ve ekibimizce geliştirilen Ciao-Sherpa versiyonu kullanılarak ardıl ışınım fiziksel paremeterleri belirlendi. Bu çalışmada, örnek olarak bir uzun GIP ve bir kısa GIP ardıl ışınım fiziksel parametreleri elde edildi. Ardıl ışınım fiziksel parametreleri yani, Kinetik enerji, jet yarı açıklık açısı ve çevresel yoğunluk değerleri literatürle uyumlu şekilde bulundu.

Determination of Gamma-ray Burst Afterglow Physical Parameters

Abstract

Gamma-ray bursts (GRBs) are the most energetic events in the Universe. These bursts are observed as two components, prompt emission and afterglow emission. By using afterglow physical parameters synthetic light curves can be produced via afterglowpy software. In this study, Swift - XRT X-ray afterglows were modeled with afterglowpy by using different jet models (Top hat jet model, Gaussian jet model and Power law jet model). Afterglow emission physical parameters were determined by using the Ciao-Sherpa version of the afterglowpy jet models developed by our team, which can be applied directly to the data. In this study, one long GRB and one short GRB afterglow emission physical parameters were obtained as an example. Afterglow physical parameters namely kinetic energy, jet half-opening angle and circumburst density values were found consistently with the literature.
