Radio properties of supernova outbursts remain poorly understood despite longstanding campaigns following events discovered at other wavelengths. After ~ 30 years of observations, only ~ 50 supernovae...
We work out an effective theory of accelerated expansion to describe general phenomena of inflation and acceleration (dark energy) in the Universe. Our aim is to determine from theoretical grounds, in...
The effects of X-ray absorption variability in NGC 4395
galaxies: active – galaxies: individual: NGC 4395 – X-rays: galaxies
2011/10/8
We present a new X-ray analysis of the dwarf Seyfert galaxy NGC 4395, based on two archival XMM-Newton and Suzaku observations. This source is well known for a series of remarkable properties: one of ...
We present an analysis of the B-band and V-band rise-time distributions of nearby Type Ia supernovae (SNe Ia). We use a two-stretch template-fitting method to measure the rise and decline of BV light ...
EVLA Nova Project Observations of the Classical Nova V1723 Aquilae
Project Observations Classical Aquilae
2011/10/8
We present radio light curves and spectra of the classical nova V1723 Aql obtained with the Expanded Very Large Array (EVLA). This is the first paper to showcase results from the EVLA Nova Project, wh...
The Optical Gravitational Lensing Experiment. Dwarf Novae in the OGLE Data. I. Three New Dwarf Novae: One in the Period Gap and Two Longer Period Objects
novae, cataclysmic variables – binaries: close – surveys
2011/10/8
We report serendipitous discovery of three new dwarf novae which eruptions in 2010 were observed by the ongoing microlensing survey OGLE-IV. All three objects are located in the Galactic bulge fields ...
Gamma Ray Burst origin and their afterglow: story of a discovery and more
Burst origin afterglow: story discovery more
2011/9/29
In this paper we review the story of the BeppoSAX discovery of the Gamma Ray Burst afterglow and their cosmological distance, starting from their first detection with Vela satellites and from the effo...
There is a wide consensus in the astrophysics community that the mechanism underlying the observed Classical Nova eruptions is a surface thermonuclear runaway. We start this short review with the main...
The remnant of SN1987A revealed at (sub-)mm wavelengths
circumstellar matter – supernovae: individual: SN1987A – ISM: ISM
2011/9/29
Context: Supernova 1987A (SN1987A) exploded in the Large Magellanic Cloud (LMC). Its proximity and rapid evolution makes it a unique case study of the early phases in the development of a supernova re...
Catastrophic quenching in alpha-Omega dynamos revisited
Catastrophic quenching alpha-Omega revisited
2011/9/27
At large magnetic Reynolds numbers, magnetic helicity evolution plays an important role in astrophysical large-scale dynamos. The recognition of this fact led to the development of the dynamical alpha...
LHC撞出迷你版“宇宙大爆炸”
LHC 迷你版 宇宙大爆炸
2010/11/11
据英国《每日邮报》2010年11月9日报道，科学家借助欧洲大型强子对撞机(LHC)，让铅离子以接近光速的速度对撞，成功创造出了迷你版的“宇宙大爆炸”，产生了一个温度为太阳核心温度100万倍的火球，也意味着产生了夸克—胶子等离子体。在宇宙大爆炸初期，正是这种夸克—胶子等离子体填满了整个宇宙。科学家表示，该项科研成果将用于解释137亿年前宇宙诞生之初的物质形成过程。

北京时间2010年9月28日消息，据国外媒体报道，美国布鲁克海文国家实验室资深科学家拉吉-维努帕兰近日透露，欧洲大型强子对撞机可能已经在某种程度上复制出宇宙大爆炸后第一时刻的情形，重新制造出宇宙大爆炸后第一时刻出现的物质。
宇宙大爆炸发生在“绝对”混沌之中--此一现象可由数学工具加以检验
宇宙大爆炸 “绝对” 数学工具
2010/9/16
据美国物理学家组织网2010年9月8日（北京时间）报道，美国西北大学物理学家运用严格的数学参数，论证了宇宙在大爆炸及其后的膨胀时期，就已经是高度混乱无序的状态，而且这种混沌并非相对，而应是绝对的。这项研究报告发表在《数学物理通讯》上。

中国科学家首次观测到完整的超新星爆发过程
首次 超新星爆发
2010/2/24
乌鲁木齐天文站站长王娜日前表示，新疆科学家刘祥完整地捕捉到银河星系外一个极难观测到的超新星爆发天象，这对研究恒星演化具有重要意义。这也是中国科学家首次观测到完整的超新星爆发过程。
