Spectroscopic evidence for helicity in explosive events
Sun: UV radiation—Sun: transition region— Sun: chromosphere
font style='font-size:12px;'>
2011/9/30
We report spectroscopic observations in support of a novel view of transition region explosive events, observations that lend empirical evidence that at least in some cases explosive events may be not...
A2163: Merger events in the hottest Abell galaxy cluster II. Subcluster accretion with galaxy-gas separation
Galaxies clusters general – Galaxies intergalactic medium – X-rays galaxies clusters

2010/11/16
Located at z = 0.203, A2163 is a rich galaxy cluster with an intra-cluster medium (ICM) that exhibits extraordinary properties,including an exceptionally high X-ray luminosity, average temperature, an...
Dwarf archaeology: Probing the first enrichment events with low-luminosity galaxies

2010/12/27
We present a novel way to utilize metal-poor stars in the local, ultra-faint dwarf galaxies (UFDs) to learn about the formation process of the first galaxies. Since UFDs have much simpler star formati...

2009/5/27
Using analytical and numerical methods, estimates are given of future predictions in astrophysics that can be gathered from a sequence of observed events, for example for γ-ray bursts. Some general pr...

In view of the renewed interest in the study of energetic particles
in the outer radiation belt of the earth, we feel it will be helpful in
looking for the energy dependence of the electron energy s...
