The Prediction,Verification,and Significance of Flank Jets at Mid-Ocean Ridges
Prediction Verification Significance Flank Jets Mid-Ocean Ridges

2015/7/14
One aspect of ocean flow over mid-ocean ridges that has escaped much attention is the capacity of a ridge to convert oscillatory flows into unidirectional flows. Those unidirectional flows take the fo...
The pulsar B2224+65 and its jets: a two epoch X-ray analysis
X-ray B2224+65
font style='font-size:12px;'>
2014/12/22
We present an X-ray morphological and spectroscopic study of the pulsar B2224+65 and its apparent jet-like X-ray features based on two epoch Chandra observations. The main X-ray feature, which shows a...

2011/10/9
The discovery of high-energy (E>100 MeV) gamma rays from Narrow-Line Seyfert 1 Galaxies (gamma-NLS1s) has confirmed the presence of powerful relativistic jets in this class of active galactic nuclei (...
Nonradial and nonpolytropic astrophysical outflows IX. Modeling T Tauri jets with a low mass-accretion rate

font style='font-size:12px;'>
2011/10/8
Context: A large sample of T Tauri stars exhibits optical jets, approximately half of which rotate slowly, only at ten per cent of their breakup velocity. The disk-locking mechanism has been shown to ...
Deep Multiwaveband Observations of the Jets of 0208-512 and 1202-262

2011/10/8
We present deep {\it HST, Chandra, VLA} and {\it ATCA} images of the jets of PKS 0208--512 and PKS 1202--262, which were found in a {\it Chandra} survey of a flux-limited sample of flat-spectrum radio...
Are low luminosity GRBs generated by relativistic jets?
low luminosity generated relativistic jets

2011/9/29
Low luminosity gamma-ray bursts (ll-GRBs) constitute a sub-class of gamma-ray bursts (GRBs) that plays a central role in the GRB-supernova connection. While ll-GRBs differ from typical long GRBs (LGRB...

font style='font-size:12px;'>
2011/9/28
The morphologies of detected jets in X-ray binaries are almost as diverse as their number. This is due to different jet properties and ambient media that these jets encounter. It is important to under...
