For the first time, we study the radio afterglow behavior during the trans-relativistic phase of the fireball shock wave. Considering the trans-relativistic shock dynamic and the synchrotron self-absorption effect of the relativistic electrons on the radio emission, we find that the dense medium model can not only explain the fast decline of the X-ray and optical afterglows of GRB980519, but also account for its radio afterglow quite well.

我們首次研究了致密介質(zhì)情形下射電余輝在跨相對論階段的行為亚洲图片无码一区二区最新，發(fā)現(xiàn)考慮到激波的跨相對論動力學(xué)和相對論電子的同步自吸收效應(yīng)對射電輻射的影響亚洲黄色第一页，致密介質(zhì)模型既可以解釋GRB980519的快速衰減的X射線和光學(xué)余輝，也可以很好地解釋其射電余輝的特點按摩深夜A级毛片视频免费。

Chapter 2 to 5 are my works on afterglows.

從第二章到第五章是本人在余輝方面的幾個工作亚洲九九av。

The study in my thesis focuses on the GRB afterglows.

本論文的研究集中在伽瑪暴的余輝方面。

Shortly after the discovery of afterglows, a standard fireball shock model has been established.

實際上黄色丝袜a片，在余輝發(fā)現(xiàn)后不久色色色色精品视频，一個關(guān)于γ暴及其余輝的標準火球激波模型就已建立了起來黑人免费肏大屄视频。

There, they strike gas previously shed by the star and heat it, which generates short-lived afterglows in many wavelengths.

在那里，他們罷工天然氣以前下跌的明星和熱量av在线免费观看不卡一区，這會產(chǎn)生短暫的afterglows在許多波長国产一级优女在线视频。

Afterglows from short GRBs have not been detected yet, which are waiting for the coming up satellites.

短暴的余輝目前還沒有發(fā)現(xiàn)，這有賴于不久將來發(fā)射的下一代衛(wèi)星免费一级a毛片,在线播放视频。

The history and actuality of the observational and theoretical studies on gamma-ray bursts and their afterglows are reviewed, the theoretical models of this field are introduced in detail, and some problems of these models are discussed.

本文概述了gamma射線暴及其余輝觀測和理論研究的歷史及最新進展99国产精品自在自在久久，詳細介紹了gamma射線暴領(lǐng)域的理論模型以及存在的問題，并介紹了本人在碩士研究生期間所做的gamma射線暴分類和光變曲線研究方面的工作国产大学生私拍视频在线。

Due to that the radio afterglows of GRBs show significantly different behavior from the optical and X-ray afterglows, studies on them become very important and should be fruitful.

暴的觀測也發(fā)現(xiàn)了射電余輝黄色网站久久久久，因射電余輝隨時間的演化與光學(xué)和X射線余輝有顯著不同，研究射電余輝的行為便具有特別重要的意義欧美大胆丰满熟妇XXBB。

Based on the standard blast-wave model, we study some aspects of afterglows, including the jet effect, reverse-shock radiation, early afterglows of short bursts, and neutrino emissions in afterglows, etc.

基于標準的沖擊波模型免费-级无码婬片AAAA片，本論文就余輝的各個方面進行了研究，包括噴流效應(yīng)污网站黄色、反向激波輻射一级毛片免费网站看、短暴早期余輝和余輝中的中微子輻射。

The researches include the dense medium effect on the evolution of afterglows, constraints on the physical parameters of GRBs, the origin of the energetic gamma-ray emission from GRBs, the inverse Compton spectra in the very early afterglows, and energy source mechanism of the supernova-GRB connection.
